The important role of magnesium-calcium refractory raw materials and additives on product performance
Magnesium-calcium-based refractories have a series of excellent properties, especially the function of purifying molten steel. At present, magnesia-calcium refractories are mainly used for continuous casting tundish lining, out-of-furnace refining ladle AOD, VOD furnace, electric furnace, conver...Read more -
Wear analysis and refractory material selection of castables at each position of circulating fluidized bed boiler
Circulating fluidized bed (CFB) boiler technology is a relatively mature clean combustion technology. CFB boilers have excellent fuel adaptability and can burn almost any fossil fuel. Limestone can be directly put into the furnace to remove 90% of SO2, and the emission concentration of NOx is lo...Read more -
What are the types of corundum bricks
Corundum brick is a general term for refractory bricks. Corundum bricks are actually divided into various grades and different corundum materials. In general, refractory bricks with aluminum content greater than 85% are called corundum bricks, and corundum can be divided into brown corundum, whit...Read more -
How to choose refractory materials for each part of blast furnace
The blast furnace is the most common steel-making equipment. In simple terms, iron ore, coke, etc. are fed proportionally from the top of the furnace to the lower tuyere, and then enter the high-temperature blast of 1,000 to 1,200 degrees Celsius, and are oxidized in the blast furnace. The reduc...Read more -
