Description

High-temperature smelting equipment for RKEF method

Technical Field

The invention relates to the technical field of smelting, in particular to high-temperature smelting equipment for an RKEF method.

Background

In the production of a blast furnace, iron ore, coke, and a flux (limestone) for slag formation are charged from the top of the furnace, and preheated air is blown through tuyeres located along the periphery of the furnace at the lower part of the furnace. Carbon in coke (some blast furnaces also blow auxiliary fuel such as coal dust, heavy oil, natural gas and the like) at high temperature is combusted with oxygen blown into air to generate carbon monoxide and hydrogen, and oxygen in iron ore is removed in the ascending process in the furnaces, so that iron is obtained by reduction. The smelted molten iron is discharged from the iron notch. Unreduced impurities in the iron ore are combined with fluxes such as limestone to generate slag, and the slag is discharged from a slag hole. The generated gas is discharged from the top of the furnace, and is used as fuel for hot blast stoves, heating furnaces, coke ovens, boilers and the like after dust removal. The main products of blast furnace smelting are pig iron, and blast furnace slag and blast furnace gas are also by-products.

The existing high-temperature smelting equipment for the RKEF method has the defect in the using process, and the smelting material cannot be crushed in a grading way, so that the yield is not high during smelting.
