3.2 t steel ingot mold capable of preventing secondary shrinkage cavity

Abstract

The invention discloses a 3.2 t steel ingot mold capable of preventing secondary shrinkage cavity. The 3.2 t steel ingot mold comprises a base, wherein a sealing block is arranged in the middle of thetop of the base in a penetrating manner, the bottom of the sealing block penetrates through the base and extends to an inner cavity of the base, ear plates are both fixedly connected to the front side and the back side of the two sides of the base, the front surfaces of the ear plates are connected with clamping strips in a penetrating mode, the outer sides of the clamping strips are connected with a bottom plate in a sleeve mode, and one side, away from the base, of the top of the bottom plate is fixedly connected with a side plate, one side, close to the base, of the side plate is providedwith a sliding groove, a heating groove is formed in the top of the base, and heating wires are arranged at equal intervals in an inner cavity of the heating groove. According to the mold, through thecooperation of the ear plates, the bottom plate, the side plate, the sliding groove, lifting ears and clamping grooves for using, the problem that a traditional steel ingot production mold is inconvenient to fix and place is solved; and through cooperation of a sealing block, a heat preservation cap, the heating wires, a heating groove and through holes for using, the problem that the secondary shrinkage cavity is easily caused by the traditional steel ingot production is solved.

Description

technical field [0001] The invention relates to the technical field of steel ingot production equipment, in particular to a 3.2-ton steel ingot mold for preventing secondary shrinkage cavities. Background technique [0002] The molten steel is poured into the casting mold through the ladle and solidified to form a steel ingot. The one that appears at the center of the top of the ingot is called the primary shrinkage cavity, and the one that appears at the middle and lower part of the steel ingot is called the secondary shrinkage cavity. The primary shrinkage cavity in contact with air, the surface is oxidized, and it is difficult to weld during plastic processing. [0003] At present, in the process of steel ingot production, due to the production process and shaping molds, shrinkage cavities are easy to occur when the steel ingots are poured. Although the secondary shrinkage cavities are not exposed to air, thermal processing under high temperature and large compression rat...
