Definitions

  • the present invention deals with the vacuum coating of steel.
  • Metallic coating of steel sheets is currently performed by hot dipping in a metallic bath. Immediately above the bath, liquid metal is wiped by gas knives to adjust coating thickness. In the case of a galvanizing line, the steel sheet must be heated from 500 to 550°C to pass in the metal bath while avoiding zinc solidification before the gas knives.
  • the coating thickness range of conventional hot dip coating technology is limited by the process. Bare spots may appear at the lower limit if the wiping pressure is excessive, or liquid metal dripping if the wiping pressure is insufficient at the upper limit of the coating thickness range. Furthermore, it is impossible to hot dip again a coating layer because the metal coating would melt.
  • Vacuum coating is the deposition of a source material, for example, from the crucible of a vacuum evaporator, on a substrate to form germs (nucleation), which gradually develop (growth) and result in an ordered coating layer.
  • Vacuum coating process is not limited regarding the thickness of the coating deposited. Vacuum deposition can be performed by several successive steps to increase the coating thickness.
  • Hot rolled steels offers applications where a high corrosion resistance is needed, for examples chassis parts of automobile or in agricultural environment. It also offers application where a minimal corrosion resistance is needed. In other words, the thickness of the corrosion protection needed for hot rolled steels is wide.
  • the surface is covered by a mill scale resulting from the contact of hot steel with air at the hot rolling mill.
  • Said scale is composed of iron oxides which are layered.
  • the thickness of the scale is from 0.5 to 8 mm. It is porous and brittle and must be removed prior to coating, else the coating wouldn’t adhere to the hot rolled steel.
  • the patent CN 113846291 discloses a cleaning and coating-plating combined unit for a galvanized steel sheet and a production method of the cleaning and coating-plating combined unit.
  • the plasma cleaning can not only realize the descaling of a hot rolled sheet, but also realize the surface cleaning of a cold rolled sheet.
  • a first object of the present invention is to provide a manufacturing method to produce a coated steel sheet by vacuum deposition. This object is achieved by the method of claims 1 to 8.
  • a second object of the present invention is to provide an equipment able to produce a coated steel sheet by vacuum deposition. This object is achieved by the equipment of claims 9 to 13.
  • a third object of the present invention is to provide a coated hot rolled steel sheet. This object is achieved by the steel sheet of claims 14 to 18.
  • a first object of the invention is achieved by a method for manufacturing a steel sheet comprising the following steps: a. Providing a steel sheet 10, b. Descaling said steel sheet by acid pickling, c. Feeding said descaled steel sheet into a pressurized chamber 3 above the atmospheric pressure, said pressurized chamber comprising an inlet 2, and being connected via at least one sealing lock 20 to at least one vacuum deposition chamber 4, d. Depositing a metallic coating layer by vapor deposition at sonic speed, wherein a gas is blown into the pressurized chamber 3 to keep it at a pressure above atmospheric pressure, said gas being released through the inlet 2.
  • the steel sheet used in the present invention is a hot rolled steel sheet.
  • the steel sheet of steps a. and b. has been hot rolled but has not been cold rolled.
  • the steel sheet of steps a. and b. has a thickness from 1.5 to 30.0 mm, preferably from 1.5 to 20 mm, advantageously from 1.5 to 10.0 mm.
  • hot rolled steel sheets have a thickness from 1.5 to 5.0 mm.
  • Specific hot rolled steel sheets have a thickness from 2.0 to 4.0 mm.
  • the descaling at step b) occurs by acid pickling, preferably at a temperature from 60 to 90°C.
  • Acid pickling produces emissions of corrosive acidic vapor and droplets. Such vapor or droplets are highly corrosive. If they penetrate the vacuum chamber, they will deteriorate the equipment in chamber.
  • the acid pickling step can include a rinsing and a drying sub-step. However, this may not be sufficient to prevent acidic vapor or even droplets to be sucked by the low pressure of the vacuum chamber 5. The inventors have found that the pressurized chamber solves this issue. After descaling by acid pickling, the steel sheet may be shortly exposed to air when transported to the vacuum deposition chamber.
  • the pickled surface When the pickled surface is exposed to air, it becomes immediately oxidized by the oxygen of the atmosphere. A resulting oxide is formed on the surface. It is composed of the elements comprised in the steel sheet. It comprises more than 50 wt% of iron oxides. For example, it can also include aluminum oxides as well as magnesium oxides, depending on the chemical composition of the steel.
  • the thickness of this layer of metal oxides is from 3 to 60 nanometers, more usually from 3 to 20 nm. The thickness of said oxide layer is usually measured by mean of Auger electron spectroscopy.
  • the steel sheet enters the pressurized chamber through the inlet 2, which acts as a neck having closer walls than the chamber itself and forms a narrow passage.
  • the steel sheet leaves the pressurized chamber through the sealing lock 20.
  • a gas is blown into the pressurized chamber 3 to keep it at a pressure above atmospheric pressure, said gas being released through the inlet 2.
  • the gas can be blown by any mean.
  • the volume of the pressurized chamber can be continuously filled by a fan blowing gas into the pressurized chamber.
  • the pressure in the pressurized chamber is continuously monitored by adjusting the gas flow rate blown in said chamber according to said monitored pressure.
  • the flow rate filling the pressurized chamber is from 500 to 15 000 Nm 3 /h.
  • said flow rate is of more than 2 000 Nm 3 /h, advantageously more than 5 000 or even 10 000 Nm 3 /h.
  • Nm 3 means normal cubic meter.
  • 1 Nm 3 is the amount of gas which when dry, occupies 1 m3 at a temperature of 0°C and at an absolute pressure of 101 ,3 kPa.
  • Nm 3 /h is a unit for volumetric flow rate of gas at a temperature of 0 °C and pressure of 101 ,3 kPa, expressed in m 3 /h.
  • the pressurized chamber of step c) has a pressure from 10 to 20 000 Pa above the atmospheric pressure or even better a pressure from 1 000 to 15 000 Pa or from 5 000 to 15 000 Pa above the atmospheric pressure.
  • the pressure in the pressurized chamber is less than 10 Pa above the atmospheric pressure, air containing acidic droplets will flow in the vacuum chamber.
  • the sealing lock 20 may not be tight enough and the vacuum may be broken in the vacuum chamber.
  • the pressure in the pressurized chamber is of more than 2 000 Pa over the atmospheric pressure, advantageously more than 4 000 Pa, or even more than 6 000 Pa.
  • the pressurized chamber is filled with inert gas, for example argon.
  • the pressurized chamber is filled with filtered and dried air sucked outside a building that houses said pressurized chamber. Outside air is filtered to remove impurities and dried to remove moisture.
  • the steel sheet After leaving the pressurized chamber, the steel sheet is transported towards the vacuum chamber. This may occur for example by multistage differential sealing locks which introduce the steel sheet progressively into lower pressure.
  • a primer layer having a thickness from 2 to 15 nm is applied under vacuum on the steel sheet to improve adhesion of the coating.
  • This primer layer is made of metal. It can be applied on the steel sheet by any mean. For example, it is applied by magnetron sputtering.
  • the primer layer consists of stainless steel containing from 10 to 13% by weight nickel, from 16 to 18% by weight chromium, the remainder being iron and potential impurities resulting from the fabrication process.
  • the primer layer contains at least 8% by weight nickel and at least 10% by weight chromium, the rest being iron and impurities resulting from the fabrication process.
  • the steel sheet is heated in the vacuum chamber at a temperature from 80 to 200°C, preferably of more than 100°C and less than 150°C, and advantageously from 120 to 140°C. This ensures a better compacity of the deposited layer.
  • Optional heating can be carried out by any mean, for example by induction.
  • the inductor to heat the steel sheet can be placed outside the vacuum chamber.
  • the metallic coating is applied on the steel sheet by JVD (Jet Vapor Deposition).
  • the JVD method is a vacuum deposition method in which metal vapor is generated by inductively heating a crucible.
  • Said crucible contains a bath of the coating metal in a vacuum enclosure.
  • the steam escapes from the crucible via a conduct that transports it to an ejector comprising an exit orifice.
  • Said orifice is calibrated, to form a jet at the speed of sound directed at the surface of the substrate to be coated.
  • the coating layer is applied by jet vapor deposition at sonic speed.
  • the installation is equipped with several ejectors. Several layers of coating are formed on top of each other.
  • the coating is multi-layered. It comprises 2 or more layers, preferably from 2 to 5 layers.
  • the line speed is limited by the targeted thickness. Indeed, the faster the line speed, the thinner the coating layer.
  • One of the benefits of the multilayer coating application by several ejectors is the possibility to increase the line speed while keeping the same coating thickness. This allows to increase the productivity.
  • a monolayer coating has a thickness from 2.0 to 10.0 pm, preferably from 2.0 to 7.5 pm.
  • a multilayer coating has a thickness from 10.0 to 75.0 pm, preferably from 10.0 to 55 pm. This way, the coating can be produced at higher line speed than a monolayer coating.
  • the metallic coating consists of zinc and residual impurities coming from the manufacturing process up to 0.1 weight %.
  • the metallic coating comprises from 0.5 to 40 weight % magnesium, residual impurities coming from the manufacturing process up to 0.1 weight %, the balance being zinc.
  • the metallic coating comprises from 0.5 to 20 weight % magnesium, and from 0.5 to 20 weight % aluminium, residual impurities coming from the manufacturing process up to 0.1 weight %, the balance being zinc.
