Abstract

The invention relates to the technical field of chemical engineering materials, in particular to a coke for protecting a blast furnace. The coke for protecting the blast furnace comprises the following components in percentage by weight: 80-90% of fixed carbons, 0.75-3% of volatile matters, 10-15% of ash, 3-9% of TiO2, and 0.9-2% of S. The invention aims to provide the coke for protecting the blast furnace; and the coke is stable in use level of TiO2 and lower in cost.

Description

technical field [0001] The invention relates to the technical field of chemical materials, in particular to coke for protecting blast furnaces. Background technique [0002] In recent years, the rapid economic development has also promoted the development of heavy industry. Most of today's heavy industrial enterprises have expanded their production to allow blast furnaces to operate at high intensity. Although this can increase production, if such high-intensity production is carried out for a long time without maintenance of the blast furnace, accidents of the blast furnace burning through the bottom of the furnace will easily occur. Now, some companies will choose to add TiO2-containing materials to maintain the hearth, that is, most of them will add vanadium-titanium magnetite lump ore. However, the price of vanadium-titanium magnetite lump ore is more expensive, and the TiO2 contained in the lump ore is also unstable, so it is difficult to determine the amount of addit...
