[0002] In the metallurgical industry, blast furnace iron-making iron-hole mud sleeves are an important channel for blast furnace iron tapping. Traditional iron-hole mud sleeves are made of brown corundum, silicon carbide, and coke powder as the main raw materials, and soft clay and sericite are used as binders. It has a high content of silica, which affects the strength and corrosion resistance of the product, and directly affects whether the blast furnace is smooth.
At present, domestic blast furnaces are all cast or rammed with refractory materials, which are difficult to manufacture and have a low service life. The time of the mud cover is as long as several hours, causing a iron hole to be exposed twice or even three times in a row, which increases the labor intensity of the workers and buryes safety hazards
