Heat resistance degree and manufacturing process of heat resistant steel furnace
Heat resistant steel furnace pot is a kind of accessory used in heat treatment electric furnace. Its commonly used materials are CrMnN, ni7n, 2520 and other heat-resistant steels. The heat resistance degree of different materials is different. For example, Cr-Mn-N furnace is suitable for 850 ℃ ~ 900 ℃; zg35cr24ni7n furnace is suitable for 900 ℃ ~ 1050 ℃; zg40cr25ni20si2 furnace is suitable for 1050 ℃ ~ 1150 ℃.
Heat resistant steel furnace can be divided into bell type furnace, nitriding furnace, carburizing furnace, octagonal tank, drum furnace, heat treatment furnace, chromium manganese nitrogen furnace, centrifugal furnace, etc. according to the use and material shape of heat-resistant steel furnace, it can be divided into bell type furnace, nitriding furnace, carburizing furnace, octagonal tank, drum furnace, etc.; it can also produce non-standard furnace according to the customer's needs, which can withstand 1150 ℃ high temperature, is not easy to change, heat and corrosion resistance.
At present, there are two kinds of heat-resistant steel furnaces and tanks. One is casting and the other is welding. The best welding material is Swedish plate 310S, which can last for 2-5 years. Moreover, this kind of heat-resistant steel furnace pot has lighter weight, faster heating, more power saving and better quality.
Of course, the centrifugal casting process can also be used for heat-resistant steel furnace and tank. The process of centrifugal casting seamless pipe is applied to the casting furnace and tank. The tube wall structure has high density, the thickness of pipe wall is uniform up and down, which is more robust and durable. It is not easy to occur the situation of high temperature and easy deformation. The service life of the product is more than 1 year, and the product advantages are more obvious.
In a word, heat-resistant steel furnace and tank products basically have a series of advantages, such as high temperature resistance, high strength, not easy to deform and good oxidation resistance. Therefore, the furnace and tank are widely used in heat treatment, and can also meet the requirements of special castings in metallurgy, mining, petrochemical, shipbuilding, building materials, electric power, light industry, machinery, military industry and other industries.
In fact, in addition to the heat-resistant steel furnace and pot, there are many similar heat-resistant steel workpieces, which are introduced to meet the special requirements of processing. As a kind of material with special properties, heat-resistant steel has many uses and can play an important role in various industries.
