Abstract

The invention discloses a vanadium titano-magnetite smelting blast furnace yield improving technology, and belongs to the technical field of vanadium titano-magnetite smelting. Through loading programmodification, a manner of rawore bottoming and rawore and waste steel material joint loading is adopted in development, a waste steel material is prevented from making contact with a weighing hopperand a loading main belt, the aim of protecting the weighing hopper and the main belt is achieved, the waste steel material is mounted on the rear segment to enter a blast furnace, the arranging position is close to the center of the blast furnace, the phenomenon that in the descending process of furnace burdens, waste steel directly makes contact with a furnace wall, and the furnace wall is damaged can be avoided, the blast furnace long service is facilitated, the vanadium titano-magnetite smelting comprehensive furnace entry grade can be improved, and the technology is a brand new technologyof vanadium titano-magnetite intensified smelting.

Description

technical field

[0001] The present invention relates to a kind of vanadium-titanium magnetite smelting, particularly relate to a kind of vanadium-titanium magnetite smelting blast furnace production raising technology, belong to vanadium-titanium magnetite smelting technical field. Background technique

[0002] 1. The status quo of intensified smelting of ordinary ore

[0003] Most of the blast furnaces in China are smelted with ordinary ore. At present, the methods of increasing the smelting intensity of all enterprises are basically the same. The production of molten iron is increased by increasing the blast volume and enriching oxygen. Enterprises, the effect of increasing production is obvious.

[0004] 2. Status quo of enhanced smelting of vanadium-titanium magnetite

[0005] At present, the domestic vanadium-titanium magnetite smelting enterprises include Panzhihua Iron and Steel, Chenggang, Jianlong, Chuanwei, Desheng, and Dagang. To increase the output of molten i...
