Steel smelting furnace convenient for adding auxiliary materials

Abstract

The invention discloses a steel smelting furnace convenient for adding auxiliary materials. The steel smelting furnace comprises a supporting frame, a fixing plate and a furnace body, wherein the supporting frame is of a U-shaped structure, a crawling ladder is arranged on one side of the supporting frame, the fixing plate is arranged on the inner wall of the supporting frame, the furnace body is arranged in the middle of the fixing plate, the furnace body penetrates through the fixing plate and extends to the position below the fixing plate, supporting legs are arranged on the two sides of the bottom of the furnace body, a first motor is arranged on one side of the top end of the supporting frame, a shaft part of the first motor is connected with a screw rod, and one end of the screw rod is connected with a baffle plate. During use, molten iron is injected into a barrel body, and the first motor is started to enable the screw rod to rotate, so that the barrel body is moved right above a feeding port of the furnace body, a third motor is started, a gear drives a rack to rotate, so that the barrel body is inclined, molten iron in the barrel body falls into the furnace body along a water guide groove, the molten iron is prevented from being poured manually, and the situation that when the molten iron is poured manually, the molten iron splashes and hurts the human body is effectively prevented.

Description

technical field [0001] The invention relates to the technical field of iron and steel smelting, in particular to an iron and steel smelting furnace which is convenient for adding auxiliary materials. Background technique [0002] Most modern ironmaking uses blast furnace ironmaking, and some use direct reduction ironmaking method and electric furnace ironmaking method. Steelmaking mainly uses pig iron smelted in blast furnaces, sponge iron smelted by direct reduction ironmaking, and scrap steel as raw materials, which are smelted into steel by different methods. The basic production process is to smelt iron ore into pig iron in an iron-smelting furnace, then use pig iron as raw material to smelt steel by different methods, and then cast it into ingots or continuous casting slabs. [0003] In iron and steel smelting, it is often necessary to add auxiliary materials such as additives to assist in the smelting of steel. In actual production operations, the addition of auxiliar...

AI Technical Summary

Problems solved by technology

[0003] In iron and steel smelting, it is often necessary to add auxiliary materials such as additives to assist in the smelting of steel. In actual production operations, the addition of auxiliary materials usually requires manual operations. The addition of auxiliary materials into the casting furnace greatly increases the labor intensity of the workers and reduces the work efficiency. In addition, the artificial addition of auxiliary materials cannot guarantee the accuracy of the input amount of auxiliary materials. Therefore, those skilled in the art provide a convenient method for adding auxiliary materials. iron and steel smelting furnace, to solve the problems raised in the above-mentioned background technology
