Abstract

The invention belongs to the technical field of improving the internal quality of high-carbon steel, and particularly relates to a method for improving the internal quality of high-carbon steel in the continuous casting process. The method comprises the following steps that 1, the parameter of an electromagnetic stirring crystallizer is set; 2, the coil parameter of the electromagnetic stirring crystallizer is set; 3, the water volume parameter of the crystallizer is set; 4, tundish black slag operation is carried out; 5, the temperature of tundish molten steel is controlled; and 6, a pouring mode is selected. The method has the beneficial effects that the set electromagnetic stirring parameter, a pull speed system, a cooling system and a temperature system are combined, and the internal quality of the high-carbon steel is improved.

Description

technical field [0001] The invention belongs to the technical field of improving the internal quality of high-carbon steel, and in particular relates to a method for improving the quality of high-carbon steel in continuous casting. Background technique [0002] High-carbon steel is mainly used to produce various types of high-strength wire rods and high-end steel strands, steel cords, etc., and has high requirements on the quality of cast slabs. For high carbon steel, some inherent physical parameters (such as solid thermal conductivity, etc.) make its central part prone to defects such as porosity, shrinkage cavity, and central segregation. Therefore, in the actual production process, reasonable technology and Effectively control process parameters to mitigate these defects. Macro-defects such as center segregation and center porosity can be avoided or improved by increasing the equiaxed crystal ratio on the cross-section of the slab. A large number of studies have shown ...
