Performance-improved novel steel pouring equipment

Abstract

The invention discloses performance-improved novel steel pouring equipment. The novel steel pouring equipment comprises a base; a mould shell is placed at the top side of the base; the two sides of the mould shell are each provided with a squeezing board; a holding cavity is formed in the base; the inner walls of the top side and the bottom side of the holding cavity are rotatably provided with asame rotating shaft; the rotating shaft is fixedly connected with a turnplate in a sleeved manner; the top side of the turnplate is fixedly provided with two circular columns; the two circular columnsare each rotatably connected with a connecting rod in a sleeved manner; and two movable holes are formed in the inner wall of the top side of the holding cavity. The novel steel pouring equipment disclosed by the invention is reasonable in structure; secondary oxidation of a material during pouring is greatly reduced, surface quality of a Monel material steel casting is increased, production costis reduced, and production can go smoothly; a pull rod is moved to drive a rack to move, and the rack moves to drive each rotating rod to rotate to squeeze the corresponding squeezing board, so thatthe mould shell can be squeezed more simply by the squeezing boards, and meanwhile, is stressed more uniformly; meanwhile, the squeezing board can be conveniently replaced to coordinate with differentmoulds; and use is convenient.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a new type of cast steel equipment with improved performance. Background technique [0002] The existing nickel-copper Monel material sand castings are directly poured into the mold after the molten steel is refined. Since the steel contains 26-33% copper, the molten steel is easily oxidized in the cavity when it contacts the atmosphere. A large number of oxidized inclusions are produced, and after PT casting, the surface defects are many and difficult to remove, which seriously affects the production cost and product delivery time, and even causes the product to be scrapped. In view of the reasons for the defects in the production process of existing materials, before the original materials are poured, Fill the cavity with liquid argon to replace the air in the cavity, reduce the secondary oxidation of the material, so as to achieve the purpose of improving the surface qua...

Problems solved by technology

There is a mold inside the mold shell, and the mold is embedded in the mold shell and it is detachable. However, in this patent, there are multiple fixing plate fixers to fix the fixing plate. This fixing needs to be fixed multiple times and needs to be replaced at the same time. When the fixed plate is used to match the mold shell, it is cumbersome to replace, so there is room for improvement
