On prolonging the service life of heat-resistant steel furnace floor
1、 Introduction of Heat resistant Steel Furnace Floor
Heat resistant steel furnace bottom plate refers to the heat resistant steel casting with high temperature resistance and oxidation resistance, which is an electric furnace accessory used to carry workpieces in industrial electric furnaces.
2、 Methods of prolonging the service life of heat-resistant steel furnace floor
First of all, users need to know their own operating temperature and environment, which directly determines what kind of heat-resistant steel furnace floor should be selected. The common materials of heat-resistant steel furnace bottom plate are chrome manganese nitrogen, nickel heptane nitrogen, 2520 and other materials. The service temperature of chromium manganese nitrogen is 850 ℃~950 ℃, that of nickel seven nitrogen is 950 ℃~1000 ℃, and that of 2520 is 1000 ℃~1100 ℃. Secondly, users should design the furnace floor in combination with their own bearing capacity. Determine whether the furnace plate is assembled or single according to the bearing weight; Whether reinforcing rib is required, and how to design it. These will affect the use of heat-resistant steel furnace floor. In the later use, it is necessary to clean the oxide skin on the surface of the heat-resistant steel furnace floor frequently, usually once a week. The above are some methods for prolonging the service life of heat-resistant steel furnace floor.

Why to produce heat-resistant steel castings?
Compared with iron castings, steel castings have higher strength, plasticity and toughness. Some heat resistant steel castings also have good weldability. Adding some alloy elements to steel castings can also obtain some special properties.
Therefore, heat resistant steel castings play an irreplaceable role in large stress and impact and special occasions, especially in mechanical manufacturing, metallurgy and chemical industry, transportation, aerospace, aviation and other sectors.
