Internal quality cast steel slabs to the radial continuous casting significantly affects the setting of support rollers. The steel passes through support rolls cools from 1400 C to a temperature of 600 C, therefore, leads to shrinkage of the material, which must respect the reduction setting profile. Figure 1 is a comparison of the density of steel at temperature for four typical carbon steel. In the temperature range 500 to1400 C shows different courses density. When setting reduction profile by means of rollers fixed to be a compromise for all the cast steel. During operation of the continuous casting rolls wear occurs, so this effect must respect reduction setting profile by means of rollers. For optimal setting of support rollers respects these compromises is used the 3D thermal model2. This reduction setting can not be optimized to ensure the production of slabs without internal defects. New the machine for continuous casting (caster) of steel are fitted with so-called soft reduction ie the managing system operated rollers position control, which allows you to set reduction profile for each particular steel, including respect for wear in cylinders. The control system is bound on on-line 3D thermal model3.
