Abstract

The invention relates to an ironmaking device, in particular to a gas-switching ironmaking device. The technical problem of the invention is to provide the gas-switching ironmaking device which can automatically switch gas to complete ironmaking, fully utilize discharged heat and autonomously control and maintain the opening of a closing door and a material blocking plate. The gas-switching ironmaking device comprises a base, a furnace body, a thermal insulation plate, a filter plate, a feeding mechanism and a combustion mechanism, and a feeding box is connected to the middle of one side of the upper portion of the base. The middle of one side of the upper part of the base is connected with the furnace body. The thermal insulation plate is connected in the furnace body. The filter plate is connected to the lower side in the furnace body and located on the lower side of the thermal insulation plate. The feeding mechanism is arranged in the feeding box. The combustion mechanism is arranged in the thermal insulation plate. A second motor is started to drive fan blades to rotate, hot gas in the furnace body is sucked in through a gas suction cover and conveyed to the raw material position of the feeding box through a conveying pipe, the effect of preheating raw materials is achieved, heat is more sufficiently utilized, and environment protection and energy conservation are achieved.

Description

technical field [0001] The invention relates to an ironmaking device, in particular to an ironmaking device for converting gas. Background technique [0002] my country's ironmaking began in the Spring and Autumn Period. It is a refining process with a long history. In a nutshell, it is the production process of reducing iron ore with a reducing agent to obtain pig iron at high temperature, and using natural gas to melt raw materials at high temperature. Ironmaking method , is also one of the means of ironmaking. [0003] The existing ironmaking technology of converting gas is to transfer the raw materials to the furnace body, inject natural gas and air, and under the action of the furnace head, melt the raw materials, discharge the molten iron and impurities, and firstly melt the raw materials at high temperature in the furnace body. The heat is completely wasted, the impurity discharge opening is always open, and the impurities keep falling out, which is uncontrollable. If...
