Description

Technical Field

[0001] The utility model belongs to the technical field of metal smelting, and specifically relates to a slag ditch which can be used for smelting iron from vanadium-titanium ore. Background Art

[0002] The main method for smelting vanadium-titanium magnetite in blast furnace is to sinter vanadium-titanium iron concentrate and ordinary powder ore to produce sintered ore, use vanadium-titanium iron concentrate and ordinary iron concentrate to make balls to produce oxidized pellets, and then add sintered ore, pellets and a small amount of lump ore into the blast furnace in a certain proportion with coke, and burn coke in the lower blast furnace to produce reducing gas. The rising reducing gas and the falling charge reduce the ore, which then melts and drips into the furnace to complete the ironmaking and smelting process, and realize the separation of slag and iron. In the blast furnace smelting process, the blast furnace slag ditch is an important component structure in the blast furnace iron-out platform. The original design of the slag ditch is U-shaped, and the slope is too small, which cannot effectively meet the requirements of vanadium-titanium smelting slag ditch flow, resulting in a series of phenomena such as slow slag flow rate, overflowing ditch, blockage, and difficulty in cleaning. There are certain safety risks, which affect the on-time iron-out in front of the furnace and even cause furnace condition fluctuations.

[0003] The utility model with publication number CN111850203A discloses a phase change cooling device for a blast furnace slag ditch and a blast furnace slag ditch. The material selected for the high temperature heat conductive layer of the slag ditch is a high silicon carbide carbonaceous material or graphite. The high temperature heat conductive layer can effectively protect the slag ditch, and can prevent the slag ditch from being seriously damaged due to long-term erosion and mechanical scouring of high temperature slag during blast furnace slag discharge, but the smoke generated during the slag discharge process is not treated.
