The ladle working layer comes into direct contact with molten steel, requiring it to minimize inclusions in the steel melt, enhance steel purity, and exhibit excellent resistance to erosion by molten steel and slag. This enables extended continuous casting times for thin slab ingots while facilitating easy dismantling after use to reduce labor intensity. Recent […]

A wide variety of refractory materials are used in the steelmaking process. They are primarily used to line the vessels holding molten iron and steel, as well as provide necessary furnace protection and insulation. These materials include ladle linings, converter linings, ladle linings, and tundish linings, along with a range of supporting shaped refractory materials

Factors affecting the life of the tundish in a continuous casting machine primarily include the quality of the tundish refractory and functional refractory materials. The refractory’s physical and chemical properties, such as chemical composition, bulk density, and flexural strength, must meet agreed requirements. This is fundamental to improving tundish life, and therefore requires strengthened management.

1.High-aluminum slide gate plate Disadvantages:(1) poor erosion resistance, sliding surface and casting mouth erosion is serious.(2) Poor thermal shock stability, easy to produce cracks in use. 2.Aluminum carbon slide gate plate Aluminum carbon sliding plate and experienced a non-burning aluminum carbon and sintered aluminum carbon. Unburned aluminum carbon slide gate plate in order to improve

More details about neutral ramming mass What is neutral ramming mass? Neutral ramming mass is a type of refractory material used in various high-temperature applications, particularly in the lining of furnaces and other industrial equipment that operate at extreme temperatures. What is ramming in foundry refractory mass? Ramming mass is an unshaped refractory material that

AOD furnace mainly smelts stainless steel. 75% of the world’s stainless steel is smelted by AOD furnaces. At the beginning of the AOD furnace, oxygen is blown to oxidize and decarburize. During the oxidation period, the oxidizing property of the slag is enhanced and the temperature rises to above 1700; At this time, the alkalinity

clay brick Advantages : ① clay brick at high temperatures is weakly acidic, alkaline slag erosion resistance to a bit weak, but with Al2O3 content increased and enhanced. Thermal stability than the refractory brick, magnesia brick as well.②After the blast of acceptable quality clay dried vacuum impregnation process phosphoric acid, phosphoric acid impregnated low-temperature firing

In order to meet the needs of the iron and steel industry for multi-furnace continuous casting and energy saving, and to adapt to the more and more severe conditions of use of the furnace refining, domestic and foreign researchers have been committed to the research and development of high-quality, new type, high-efficiency refractory materials, in

The trolley-type forging heating furnace is used for heating steel ingots before forging. Its furnace temperature changes with time, and the maximum furnace temperature can reach 1350℃. The working conditions of the trolley-type forging heating furnace are very harsh due to the need for working methods. The workpiece is loaded outside the furnace, and a
