Definitions

the invention relates to a process for the production of Rolling long products, especially wire, section steel, bar steel, Rails or the like suitable strands using a Continuous caster with casting mold.
the invention relates to a Continuous caster with mold to carry out the process.
the billet continuous casting plants usually pour with an open one Pouring stream between distributor and mold and with oil as a lubricant.
These continuous casting plants are predominantly for continuous sheet caster with vertically arranged mold, which in turn can be divided into vertical, vertical bend and Circular arc systems.
Blocks also become a certain but small one Percentage also cast on horizontal caster.
the ones here cast strands are mainly special steel grades, which can only absorb small bending stresses when cast.
the continuous casting machines described are used depending on the dimensions a maximum operationally realistic casting speed of operated at approx. 1.5 - 3.0 m / min.
the object of the invention is to seek a solution that both Advantages of a round mold as well as the advantages of a square billet with minimal use of additional devices such as e.g. B. has forming frames in the strand guide.
the object according to claim 1 is achieved in that that the strand enters the mold at the beginning of its solidification Has round format or oval format and this round format or Oval format when conveying over the remaining mold length until the mold is released to an essentially equal extent Polygonal or profile strand format is molded.
the continuous caster is structurally characterized according to claim 7 characterized in that the continuous casting mold with a round mold format or also oval mold format in the upper mold half is provided and an indentation area starting at the latest in the middle of the mold has that over the lower half of the mold a polygonal or profile format up to the mold exit at the latest about the same size as the original round mold format Has.
the continuous casting arch system shown in Figure 1 contains the Oscillating mold according to the invention (1) with liquid steel is supplied from a distributor (2).
the steel can either be free falling from the distributor (2) (Fig. 1A) or with the help of a dip tube (3) using mold powder (4) (Fig. 1B) in the Chill mold (1) are passed.
the mold (1) according to the invention shows that in the first half (5) from the top edge (5.1) to max. a round or oval format (6) of z. B. 127 mm and in the second half (7) until the mold exit (7.1) the strand on a polygonal format of the same size (8) or the same profile (8.1).
the 127 mm round format (6) can become a 100 mm Square billet (9), which has the same circumference of 400 mm as the 127 mm round format.
the square stick can easily convex surfaces and / or have rounded corners (9.1).
the round format in the Chill to a polygon (10) such. B. like an octahedron To be circumferentially shaped.
Forming the strand from a round (6) to a polygon (8) or profile (8.1) within the continuous casting mold is easily possible, since the strand with its hot strand shell and the liquid one
the core is very ductile, has a low deformation resistance and hugs the mold well.
the billet format molded in this way then comes on the conventional one Continuous casting plant (11) for solidification (11.1) and is Rolling mill (13) fed upstream furnace (12).
the oven (12) can with a favorable arrangement of the continuous caster and a favorable choice of the strand cross-section to the strand surface be a pure temperature compensation furnace that does not leave the strand Must supply energy.
the continuous caster can be a billet system as well as one Be a pre-block system.
a typical blooming unit pours e.g. B. one Strand with the rectangular format 320 x 250 mm, for example for rail generation is used.
the corresponding round format According to the invention, a diameter would be in the mold of the mold of 363 mm and would have the same size in the mold Pre-block (14) of 320 x 350 mm molded.
the round profile of the same size can be saved in accordance with the Roll stands are getting smaller.
Such a casting profile (8.1) close to the final dimensions would correspond, for. B. the eighth intermediate profile within a classic rail calibration of 18 passes, which means that the lengthening of the rolling stock is reduced Ensuring the rail quality reduced from approx. 10 to 6 can be.
the second part of the mold which is the molding of the Stranges makes consist of mold segments.
the indentation is then carried out with the help of cooled segment plates (7.2), which are position and force controlled.
mold segments (7.2) can preferably made of copper, but also made of cast steel.
Figure 2 shows that the mold according to the invention also at Horizontal continuous casting machines can be used. Either can the strand (15) ( Figure 2A) with the help of the pulling machine (16) Hydraulic jaw drive or electric roller drive from the Mold (1), which is firmly connected to the distributor (17), conveyed out be, or the strand (15) ( Figure 2 B) with the help the pull-out machine (18) with an electric roller drive the oscillating mold (1) with flanged distributor (19) promoted.
the casting speed up to max. 10 m / min and thus the productivity of the continuous caster is strong can be raised.
the invention also leads to a minimal additional investment and unchanged in the first approximation Operating costs compared to a conventional continuous caster Rectangle strand formats.
the invention enables the simple conversion of already existing continuous casting plants with the aim of ensuring the continuous quality to improve both inside and on the surface.
