Vacuum steelmaking boiler

Abstract

The invention relates to a vacuum steelmaking boiler. The vacuum steelmaking boiler comprises a main smelting mechanism and a dumping mechanism, wherein the lower end of the main smelting mechanism ismounted on the existing working ground; the dumping mechanism is arranged at the left end of the main smelting mechanism; and the lower end of the dumping mechanism is connected with the existing working ground. The steelmaking boiler is used based on the design concept of a structure capable of being in a reciprocating motion state; the arranged main smelting mechanism can enable a vertical boiler to rotate within a certain range in the steelmaking process, so that molten steel and slag in the vertical boiler are in a shaking motion state, and the power condition of metallurgical reaction isimproved; and the arranged dumping mechanism is matched with a support rod to keep the balance degree of the vertical boiler in the molten steel overturning and dumping process, so that the motion stability of the vertical boiler is improved.

Description

technical field [0001] The invention relates to the technical field of steelmaking boilers, in particular to a vacuum steelmaking boiler. Background technique [0002] Steelmaking refers to controlling the carbon content (generally less than 2%), eliminating harmful elements such as P, S, O, and N, retaining or increasing beneficial elements such as Si, Mn, Ni, and Cr, and adjusting the ratio between elements to obtain the best performance, the use of steelmaking pig iron Put it in a steelmaking furnace and melt it according to a certain process to obtain steel. The steel products include steel ingots, continuous casting slabs and direct casting into various steel castings. The steelmaking process includes feeding, slagging, slagging, molten pool stirring, Dephosphorization and other basic processes, steelmaking methods can generally be divided into three methods: converter steelmaking, open hearth furnace steelmaking and electric furnace steelmaking. Steel (steel products...

AI Technical Summary

Problems solved by technology

[0003] 1. Common steelmaking boilers have no additional rotational movement during the steelmaking process, and the probability of molten steel and slag being in a moving state is small, which can affect the quality of the final molding of molten steel. When turning over the steelmaking boiler to dump molten steel, relying on workers Without specific auxiliary tools such as experience, it is difficult to control the pouring amount of molten steel;

[0004] 2. The molten steel pouring outlet installed on the boiler has no structure that can divert flow, so that the molten steel is prone to large-scale splashing at the moment of pouring out, and the directly open pouring outlet is not conducive to the quantitative discharge of molten steel and control the flow rate of molten steel, while there is a slag adhesion layer at the outlet end of the pouring
