Heat-resistant Steel Material Selection Factor

Material selection should pay attention to the main factors in many heat resistant steel grades, the selection of heat resistant steel in line with the working conditions of cement plant, the following factors must be considered: (1) the working temperature of heat resistant steel casting. Operating temperature means the highest temperature, normal temperature and minimum temperature and temperature rate of change.(2) Mechanical load borne by heat-resistant steel castings.(3) Heat-resistant steel casting and its contact gas, conditions (including wind speed, dust content, containing chemical composition, etc.).(4) the price is low, where can use chromium, nickel content of low casting heat-resistant steel is not high chromium, nickel content. The cement plant should continuously summarize and accumulate the experience in using heat-resistant steel castings. If there is a failure problem in use and the analysis proves that the abnormal scrap of heat-resistant steel casting is caused by improper material selection, we can contact the manufacturer to prevent the failure, and the manufacturer shall provide the re-selection data to the user factory and indicate the direction
