Definitions

• the invention relates to a device for the continuous casting of metals, in particular steel, with a base frame supporting the continuous casting mold and an oscillation device arranged on the base frame and a castor frame arranged at the foot end of the continuous casting mold.
• hydrofluoric acid is generated through the use of casting powder that mixes with spray cooling water.
• every machine part is exposed to this aggressive medium.
• Particularly sensitive assemblies such as Resonance molds, in which leaf springs are used to vibrate the continuous casting mold, suffer from such acids.
• the invention has for its object to provide better protection for the mold area and subsequently arranged assemblies of a continuous casting machine.
• the continuous casting mold is arranged together with a vibrating frame and an oscillating drive acting on the vibrating frame in a housing which closes off at the top and on the side, and in that it is attached to the continuous casting mold Castor frame penetrates a laterally shielding lower housing.
• This type of housing is particularly advantageous in the case of continuous casting molds which are oscillated in the resonance method for casting blooms, because they have a fixed base frame.
• a housing cover plate with a recess for the continuous casting mold upper part and a respective lateral housing wall are fastened to the fixed base frame of the continuous casting device. This results in a seal at the entrance of the continuous casting mold without hindering the oscillation movement.
• a co-oscillating cover is placed on the mold insert and / or a water tank through the recess.
• the cover can be kept very low and flat.
• An improvement of the invention represents that the base frame with the housing cover plate and the side housing walls forms a transportable unit that can be supported on the foundation or a steel frame. This is easy to handle using a hoist and can be largely installed fully equipped.
• the lower housing is fixedly arranged on base plates of the base frame.
• a seal can be designed between the continuous casting mold and the lower housing, which allows the continuous casting mold to move during oscillation.
• such a seal is designed such that the lower housing, which surrounds the mold foot end with play, forms a labyrinth seal.
• the arrangement, maintenance and assembly of the castor frame is also favored by the fact that the lower housing is approximately bell-shaped with step sections that enlarge downwards. The smaller diameter for the continuous casting mold can be used for the labyrinth seal.
• the oscillation device is provided with a hydraulic or electric drive motor, which is arranged on the base plate of the base frame.
• the drive motor therefore also enjoys the protection of the housing and is shielded from breakthroughs below the continuous casting mold.
• the oscillation device is provided with a hydraulic or electric drive motor which is located below the base plate of the base frame and is surrounded by a protective housing.
• the protective housing for the hydraulic or electric drive motor is provided with water cooling.
• Fig. 1 shows a vertical section through the entire assembly
• Fig. 3 is a perspective view of the upright housing
• Fig. 4 is a perspective view of the housing with an externally arranged drive motor for the oscillation device.
• the device for continuous casting of metals has a base frame 2 carrying the continuous casting mold 1 and an oscillation device 3 arranged on the base frame, a castor frame 4 being fastened to the foot end 1a of the continuous casting mold 1 (FIG. 1).
• the continuous casting mold 1 is arranged together with an oscillating frame 3b and an oscillating drive 3a engaging the oscillating frame 3b in a housing 5 which is closed off at the top and on the side.
• the castor frame 4 arranged on the continuous casting mold 1 penetrates a laterally shielding lower housing 6.
• the housing 5 is closed by means of a housing cover plate 5a, which has a recess 7 for the continuous casting mold upper part 1b, and by means of Completed one side housing wall 5b each on the fixed base frame 2 of the continuous casting device.
• a co-oscillating cover 8 is placed through the recess 7 on the mold insert 1c and / or a water tank 1d and forms a protection on the pouring side.
• the base frame 2 with the housing cover plate 5a and the two side and front and rear housing walls 5b forms a transportable unit 9 that can be supported on the foundation or a steel frame (FIGS. 2 and 3).
• the lower housing 6 is fixedly attached to the base plate 2a of the base frame 2.
• the lower housing 6 is approximately bell-shaped and has one or more step sections 11 that increase downwards.
• the oscillation device 3 is equipped with a hydraulic (or electrical) drive motor 3c and is mounted on the base plate 2a of the base frame 2.
• the oscillation device 3 has an electric (or hydraulic) drive motor 3c which is located below the base plate 2a of the base frame 2 and which is surrounded by a protective housing 12.
• the protective housing 12 is used to shield against the high heat radiation of the casting strand with water cooling, e.g. provided in the protective housing walls.
• an electromagnetic stirring coil 14 is arranged, which is thus also inside the housing 5.
• the space 13 is dimensioned such that the height of the electromagnetic stirring coil 14 can be adjusted by a selected amount, which results from the metallurgical effects.
