Sand Casting Heat Resistant Steel Selection
Among the many heat-resistant steel grades, the following factors must be comprehensively considered when selecting a heat-resistant steel that meets the working conditions of the cement plant:
(1) Use the working temperature of heat-resistant steel castings. Operating temperature refers to maximum temperature, normal and minimum temperature and rate of temperature change.
(2) Mechanical load of heat-resistant steel castings.
(3) Gas and conditions (including wind speed, dust content, chemical composition, etc.) in contact with heat-resistant steel castings.
(4) The price should be low, and those with high chromium and nickel content are not used for casting heat-resistant steels with low chromium and nickel content.
Cement plants should continuously summarize and accumulate experience in using heat-resistant steel castings. If there is a failure problem during use and it has been proved by analysis that the abnormal scrapping of heat-resistant steel castings is indeed caused by improper material selection, you can contact the manufacturer to prevent failure through research and re-selection of materials. The manufacturer should provide the user with a new material selection. information and directions.
Applicable Environment
The earliest material used in boilers and heating furnaces is low carbon steel. The temperature used is generally around 200 °C and the pressure is only 0.8MPa. Until the low carbon steel used for the boiler, such as 20g, the operating temperature does not exceed 450℃, and the working pressure does not exceed 6MPa. With the continuous increase of the operating temperature of various power devices and the rapid increase of working pressure, the operating temperature of modern heat-resistant steel has reached 700 ℃, and the operating environment has become more complex and harsh. The operating temperature range of Sand casting heat resistant steel is 200～1300℃, the working pressure is several MPa to tens of MPa, and the working environment is developed from a simple oxidizing atmosphere to a vulcanizing atmosphere, a mixed atmosphere, molten salt and liquid metal, etc. complex environment.
