Abstract

The invention provides a cooling mold and a method for cooling a steel ingot. The cooling mold includes a casting chassis and a condensation wall, and the condensation wall includes at least two cooling layers arranged in sequence along the vertical direction; the cooling mold also includes at least two pairs arranged outside the condensation wall. Electromagnetic induction components, each pair of electromagnetic induction components are symmetrically arranged on both sides of the casting cavity, and at least one pair of electromagnetic induction components are respectively set on each cooling layer; each electromagnetic induction component includes at least two pairs of slidably connected to the condensation wall Coils, two coils in each pair of coils are parallel and oppositely arranged; in each electromagnetic induction component, at least one pair of coils is arranged vertically, and at least one pair of coils is arranged horizontally, and each of the horizontally arranged coils is located at the edge of each of the vertically arranged coils. Between the center lines; the two ends of each coil are opposite or connected in turn, forming a semi-closed or closed rectangle respectively. The invention can stir the molten steel from the horizontal and vertical directions respectively, thereby improving the quality of the steel ingot.

Description

technical field [0001] The invention relates to the technical field of metallurgical casting, in particular to a method for cooling a mold and a cooling ingot. Background technique [0002] Extra-thick plates are often used in the shell of atomic power stations, high-rise building bases, offshore oil platforms, high-pressure vessels, aircraft carrier armor plates, heavy chemical reaction towers, hydropower, thermal power, wind turbine bases, etc., which belong to high performance, high purity, high added value Products, most of which require ultrasonic flaw detection, and some also require Z-direction performance. At present, there are mainly the following sources for extra-thick plate blanks: [0003] 1. In traditional cast iron ingot molds, when producing steel ingots, molten steel is injected into the cast iron ingot molds, and the ingots are cooled under natural conditions, the cooling intensity is low, the solidification speed is slow, the ingot solidification and the ...
