example 1
[0015] Example 1: Using a 1 ton medium frequency induction furnace for smelting, the chemical composition weighed according to the design scheme of the present invention is: C 0.80kg, Si 6.00kg, Mn 8.00kg, P 0.05kg, S 0.05kg, Cr190.00kg, Ni 310.00kg, Nb 10.00kg, Ti 0.30kg, Zr 0.30kg, the rest is Fe and trace impurities. After all the above ingredients are put into the furnace and melted, samples can be taken to analyze the content of the ingredients, and the slag is deoxidized. If there is any deviation in the ingredients, it should be adjusted until it is qualified. After the composition is qualified, the molten steel is well deoxidized, and the temperature meets the process requirements, steel preparations can be made.
[0016] According to the needs of users, the alloy of the present invention can be used for centrifugal casting pouring pipes, static casting pipe fittings, etc., and can also be used as steel for forgings. According to different products, different producti...
