Converter steel making device utilizing substance oxidization heat generating

Abstract

The invention relates to the technical field of steel making and discloses a converter steel making device utilizing substance oxidization heat generating. A furnace body is included, and the two sides of the furnace body are each fixedly connected with a feeding pipe; the top of the furnace body is fixedly connected with a gas inflow pipe, and the lower portion of the gas inflow pipe is movably connected with a push rod; the end, away from the gas inflow pipe, of the push rod is fixedly connected with a slide rail; the surface of the slide rail is in sliding connection with an oxidizing mechanism; a containing groove is fixedly connected to the portion, located on the lower portion of the oxidizing mechanism, in the furnace body; the two sides of the containing groove are fixedly connected with flowing openings, and solid substances can be formed and float on the upper portion molten iron; at the moment, the oxidizing mechanism is close to the surface of furnace slag, and a rotating mechanism is rotated, so that an adsorbing plate generates adsorbing face to adsorb the furnace slag; then the molten iron flows out of the flowing openings, and therefore the effect that after the furnace slag is used, the furnace slag can be cleared out without waiting that steelmaking ends is achieved; and due to the fact that the molten iron is in the containing groove, the temperature of the molten iron can be isolated and the oxidizing mechanism cannot be affected.

Description

technical field [0001] The invention relates to the technical field of steelmaking, in particular to a converter steelmaking equipment that utilizes material oxidation to generate heat. Background technique [0002] Steelmaking refers to controlling carbon content, 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; steelmaking technology There are many kinds of equipment, among which converter steelmaking is the most used; [0003] Converter steelmaking uses molten iron, scrap steel, and ferroalloy as the main raw materials, and completes the steelmaking process in the converter by relying on the physical heat of the molten iron itself and the chemical reaction between the components of the molten iron to generate heat without resorting to external energy sources; this steelmaking method Although energy-saving and high-efficiency...

Problems solved by technology

[0003] Converter steelmaking uses molten iron, scrap steel, and ferroalloy as the main raw materials, and completes the steelmaking process in the converter by relying on the physical heat of the molten iron itself and the chemical reaction between the components of the molten iron to generate heat without resorting to external energy sources; this steelmaking method Although energy-saving and high-efficiency, there is no corresponding treatment method for the used slag, because the converter steelmaking is an integrated equipment, and it works by self-heating in the steelmaking process, so the furnace body cannot be opened, which leads to internal The slag can only be cleaned out after the steelmaking is over. It is well known that when the temperature in the furnace is lowered, the slag will condense on the inner wall of the furnace and it is difficult to clean up; in addition, the converter steelmaking technology cannot fully control the temperature. Independently, in most cases, it is necessary to wait for the heat dissipation of the reactants to complete the cooling work, which will lead to prolonging the steelmaking time, so a converter steelmaking equipment that uses material oxidation to generate heat came into being
