 Heat-resistant steel production process 
 General heat-resistant steel smelting electric arc furnace or induction furnace in smelting. Often require high quality vacuum refining and refining process. Some high-alloy heat-resistant steel casting process is difficult to deformation, the casting is not only cost-effective than the roll, but there is a higher rupture strength castings. So in the heat-resistant cast steel accounts for a sizeable proportion. In addition to casting using sand casting methods, but also with the casting process to obtain a smooth surface, the exact size of the product. Of ammonia and ethylene cracking furnace tubes are often used in centrifugal casting method. Heat treatment is usually refractory steel pearlite or tempered by normalizing use; martensitic heat-resistant steel with quenching to stabilize the organization, get good mechanical properties and high temperature strength. Annealing heat-resistant steel can production line 
 Ferritic steel can not be enhanced by heat treatment. To eliminate cold processing and welding of plastic deformation caused by stress, in the 650 ~ 830 ℃ annealing, rapid cooling after annealing, so quickly through the brittle temperature range of 475 ℃. Most of austenitic steel with high temperature anti-oxidation solution heat treatment, in order to get a good cold deformability. Austenitic refractory steel with high temperature solution treatment is first, and then above the temperature 60 ~ 100 ℃ under the conditions of aging, enabling organizations of stabilization, simultaneous deposition of the second phase, in order to strengthen the matrix. More heat-resistant steel used in cast, but also heat-resistant steel according to the type with the corresponding heat treatment.
