The invention relates to the technical field of steel ingot casting, and discloses a 3.2 t steel ingot mold capable of preventing central porosity and segregation. The steel ingot mold capable of preventing the central porosity and the segregation comprises a casting groove, a first cooling groove is fixedly connected to the center of the bottom of the casting groove, a first water inlet is formedin one side of the top of the first cooling groove, a first water outlet is formed in one side of the bottom of the first cooling groove, one side of the top of the first water inlet is provided withan electromagnetic valve I, and one side of the top of a first water outlet is provided with an electromagnetic valve II. According to the 3.2 t steel ingot mold capable of preventing the center porosity and the segregation, through the casting groove, the first cooling groove, the first water inlet, the electromagnetic valve I, the electromagnetic valve II, a temperature sensor I, a cooling groove II, a water inlet II, a water outlet II, a electromagnetic valve III, a electromagnetic valve IV and a temperature sensor II, the two cooling grooves are used, the cooling speed of center of moltensteel and the cooling speed of the periphery of the molten steel are adjusted, and the cooling speed imbalance between the center and the peripheral of the molten steel is prevented to cause the central porosity and the segregation .
Description
technical field [0001] The invention relates to the technical field of steel ingot casting, in particular to a 3.2-ton steel ingot mold that prevents center loosening and segregation. Background technique [0002] Center porosity is the product of the final crystallization shrinkage of the steel ingot, and it shows that voids and dark spots are concentrated in the center of the transverse acid leaching sample. Since the gas, low melting point impurities and segregated components are all solidified in the central part, this part is easy to be corroded, and some voids and darker spots appear after acid leaching. Slight central porosity has little effect on the mechanical properties of steel. However, severe central porosity affects the transverse plasticity and toughness of steel, and sometimes internal cracks appear during processing, so severe central porosity is not allowed to exist. The main difference between it and general porosity is that voids and dark spots coexist ...
