The quality of the silicon ramming material sintering layer in the intermediate frequency furnace directly affects the service life of the furnace. The purpose of drying the furnace is to obtain the sintering layer process, which is an important link. Intermediate frequency furnace knotting material

After the intermediate frequency furnace silicon ramming material is built in the furnace cavity, it should be immediately dried. Before baking, check whether the electrical equipment and cooling water system are normal; When baking, it is necessary to strictly follow the baking process, which is a key factor in the baking process

During the baking process of medium frequency furnace silicon ramming materials, the heating speed should be controlled well, especially in the early stages of baking. If the heating speed is too fast, the moisture in the furnace lining will be discharged too quickly, which can easily form cracks and greatly shorten the life of the furnace

The melting temperature, degassing time, one-time degassing amount, chemical composition of slag, steel (iron) type produced, as well as chemical erosion of slag, structural peeling of refractory materials, and thermal erosion of intermediate frequency furnace knotting materials can all affect the damage to the lining of intermediate frequency furnace knotting materials. As the capacity of the furnace increases, the proportion of heat lost on the surface of the molten steel decreases, and the temperature of the slag is higher than that of small capacity furnaces. The fluidity of the slag is also better than that of small capacity furnaces, thus intensifying the erosion of the furnace lining. Large induction furnaces often use a method of mixing steel and slag for steelmaking, requiring slag to have good fluidity in order to adapt to the steelmaking conditions. Therefore, the erosion of the slag line is severe, which is another reason for the decrease in the service life of the furnace lining

What is the difference between ramming material and pouring material? It has high fluidity and a wide range of applications. For areas with less ramming material or less important use, manual knotting can also be used. The ramming materials are classified according to their materials, including high alumina, clay, magnesium, dolomite, zirconium, and silicon carbide carbon refractory ramming materials. There are two types of castables classified by material: 1. dense refractory castables and insulating refractory materials with a porosity of not less than 45% according to their porosity distribution; 2. According to the binder, there are hydraulic bonding, chemical bonding, coagulation bonding, and refractory casting

Castable material is currently a widely used amorphous refractory material in production and use. Mainly used to construct various heating furnace linings and other integral structures for heavy pipe rice in metallurgy, petroleum, chemical, building materials, power, mechanical industry kilns and heating equipment. High quality products can also be used for smelting

The ramming material is made of raw materials such as silicon carbide, graphite, and electrically calcined smokeless coal, mixed with various ultrafine powder additives, and bonded with electric melting cement or composite resin to form a loose material. Used to fill the gap between the cooling equipment of the furnace body and the masonry or as filling material for the leveling layer of the masonry. The ramming material has good chemical stability, erosion resistance, wear resistance, peeling resistance, and heat shock resistance. It is widely used in metallurgy, building materials, non-ferrous metal smelting, chemical industry, machinery and other manufacturing industries.
