Problems solved by technology

During production, temperature is an important criterion for smelting, but today's smelting furnaces cannot realize automatic temperature control. Therefore, when the smelting temperature is not suitable, it will inevitably cause waste of resources; Activated carbon is used for adsorption. There are two problems in this adsorption method. One is that it causes a waste of CO, and the other is that once the activated carbon is not replaced in time, it will cause CO leakage and pollute the environment.

Abstract

The invention relates to a smelting furnace, in particular to a smelting furnace capable of automatically adjusting temperature. A furnace body communicates with a hot air pipe and a smoke pipe; a temperature sensor is fixedly arranged inside the furnace body; an output end of the temperature sensor is in transmission connection with an input end of a temperature control system; an output end of the temperature control system is in transmission connection with an input end of an automatic flow valve; the automatic flow valve is arranged on the hot air pipe; a dust absorption mechanism is arranged on the smoke pipe; an air outlet end of the smoke pipe communicates with an air inlet end of a CO separation device; and an air outlet end of the CO separation device communicates with an air inlet end of a CO storage device. According to the smelting furnace capable of automatically adjusting temperature, the automatic regulation and control of the temperature are achieved, the waste of resources is avoided, the leakage of CO is avoided as well, and the environment friendliness is achieved.

Description

technical field [0001] The invention relates to a smelting furnace, in particular to a smelting furnace with automatic temperature regulation. Background technique [0002] Steel smelting is a general term for steel and iron metallurgical processes. Industrially produced iron is divided into pig iron (with a carbon content of more than 2%) and steel (with a carbon content of less than 2%) according to the carbon content. The vast majority of modern ironmaking uses blast furnace ironmaking, and individual direct reduction ironmaking methods and electric furnace ironmaking methods are used. Steelmaking is mainly based on pig iron smelted by blast furnace, sponge iron smelted by direct reduction ironmaking and scrap steel as raw materials, and steel is smelted by different methods. The basic production process is to smelt iron ore into pig iron in an iron-making furnace, and then use pig iron as raw material to smelt steel by different methods, and then cast it into steel ing...
