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 […]

UncategorizedIn 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
