Slag removing rake capable of easily and rapidly removing molten iron slag

Abstract

The invention discloses a slag removing rake capable of easily and rapidly removing molten iron slag. The rake is mainly characterized in that the upper end of a handle is provided with a high-temperature resistant silicon carbide ceramic rake body capable of easily and rapidly removing the molten iron slag; the silicon carbide ceramic rake body is composed of a circular rake head at the upper end and a cylindrical rake rod at the center of the lower end, and the upper end of the rake rod is provided with 3-4 stiffeners evenly distributed; the circular rake head, the stiffeners and the rake rod are integrally formed by hot pressing sintering; an external thread at the lower end of the rake rod of the silicon carbide ceramic rake body is in threaded connection with a threaded hole in the upper end of a connection sleeve; the upper end of the handle is inserted into a circular shrinkage pool in the lower end of the connection sleeve, and the annular end face at the lower end of the connection sleeve and the upper end of the handle are firmly welded together. When an intermediate frequency furnace melts iron, the high-temperature resistant silicon carbide ceramic rake body at the upper end of the handle can be used for easily and rapidly removing the slag out of the furnace, when the silicon carbide ceramic rake body is stuck into high-temperature molten iron in the furnace to rake off the slag, the rake body is not melted by the high-temperature molten iron, and the slag removing rake capable of easily and rapidly removing the molten iron slag is durable, so that the production and economic benefits are dramatically improved.

Description

technical field [0001] The invention relates to the technical field of smelting equipment, in particular to a slag removal rake capable of easily and quickly removing molten iron slag. The invention is suitable for rapid removal of molten slag when the intermediate frequency furnace smelts molten iron. Background technique [0002] When the intermediate frequency furnace smelts molten iron, slag appears continuously on the surface of the molten iron in the furnace. In order to purify the molten iron and improve product quality, the slag on the surface of the molten iron in the furnace must be removed. The slag agent is used to make the slag bond into a block, and then use a hexagonal steel rod to insert into the molten iron to pick out the slag on the surface of the molten iron one by one until the slag on the surface of the molten iron is removed. The existing method of removing slag It is cumbersome and slow, which affects the production progress. [0003] The existing i...
