Blast furnace molten iron using technology

Abstract

The invention discloses a blast furnace molten iron using technology. The technology specifically comprises the following steps that S1, smelting of blast furnace molten iron is performed, specifically, elemental iron is placed into a blast furnace and is smelted in the blast furnace, after the temperature in the blast furnace is increased to 1290 DEG C, a tungsten raw material and zirconium oxide particles are added into the blast furnace, smelting is continued until molten iron is generated by smelting, when the temperature of the molten iron rises to a certain temperature, an iron notch is opened for tapping, the molten iron flows through an iron runner and then enters pouring equipment, and heat preservation is conducted for standby application; and S2, manufacturing of a grinding ball semi-finished product is performed. The invention relates to the technical field of casting technologies. According to the blast furnace molten iron using technology, in the grinding ball casting process, the blast furnace molten iron is used for casting, the intermediate-frequency furnace smelting link is omitted, a large amount of electric charge and electric energy are saved, the economic cost is reduced, meanwhile, the problem that a large amount of slag and impurities are generated in a traditional casting mode is solved, meanwhile, a poured grinding ball has the higher hardness, and the wear resistance is further improved.

Description

Technical field [0001] The present invention relates to the field of casting process, in particular a blast furnace iron water use process. Background technique [0002] The blast furnace iron water is the iron water melted in the blast furnace. The iron water is commonly known as the liquid iron. Its ingredient is a single iron, which is a liquid iron. The melting point of iron is 1534 ° C, and the iron water can be poured in a mold, then solidified, made The mold shape of the mold, the density of iron water = 7138 kg / m3, iron water and a small amount of chlorine gas to form ferricide. [0003] Grinding spheres refers to aluminum aluminum, roll rod powder, industrial alumina powder, high temperature calcination A Bail method of aluminum oxide powder, etc. Drying, burnning is made. [0004] When casting milling ball, the waste iron scrap shavings are placed in the interior of the medium frequency furnace, and the casting is done, not only the large amount of power resources in ...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a process for using molten iron in a blast furnace, which solves the problems that the existing method of casting grinding balls consumes more power resources, the economic cost is large, and the large amount of impurities produced during smelting makes it difficult for personnel to clean up.
