Definitions
- the technology of continuous casting in which, by cooling a molten metal on the walls of a mold cavity of a continuous casting mold, forms a continuous shell with a continuously increasing thickness and continuously extrudes a strand from an outlet opening of the continuous casting mold, is known to apply to peritectic steels, for example steels with a Carbon content of 0.1-0.14%, to problems that are particularly evident in the poor surface quality of the strands produced. Such quality defects are undesirable, especially since further processing of the strands often leads to unacceptable quality defects in the subsequent products.
- the heat-insulating layer in the area of the first longitudinal section increases the temperature on the inside of the mold tube. Because the distance of the heat-insulating layer from the inner surface of the mold tube is at least 25% of the wall thickness of the mold tube, the wear of the mold tube during casting operation is due to the thermal and mechanical
