Embodiment 1
[0064] This example provides a method for producing nickel-based steel with high-phosphorus molten iron, P in the molten iron: 0.136%, and the chemical composition and mass percentage of the smelted product are as follows: C: 0.042%, Si: 0.3%, Mn: 0.68%, Ni: 8.92%, Alt: 0.035%, S≤0.001%, P≤0.003%, N≤0.0035%, the balance Fe and non-removable impurities.
[0065] Specifically include the following steps:
[0066] S1. The loading capacity of molten iron is 153 tons. After pouring the tank, pre-treat the molten iron and perform desulfurization operation. After desulfurization, ensure that the slag is cleaned. S: 0.0020% of the molten iron;
[0067] S2. The nickel plate is put into the furnace together with the steel scrap, and the charging amount is 22 tons, of which the nickel plate adding amount is 14 tons;
[0068] S3. Carry out slag dumping operation after converter slag splashing, slag dumping and slag remaining, the amount of slag remaining is 3 tons, after the slag dumping...
Embodiment 2
[0080] This example provides a method for producing nickel-based steel with high-phosphorus molten iron, P in the molten iron: 0.142%, and the chemical composition and mass percentage of the smelted product are as follows: C: 0.039%, Si: 0.16%, Mn: 0.72%, Ni: 9.01%, Alt: 0.029%, S≤0.001%, P≤0.004%, N≤0.0039%, the balance Fe and non-removable impurities.
[0081] Specifically include the following steps:
[0082] S1. The loading capacity of molten iron is 149 tons. After the tank is poured, the molten iron is pretreated and desulfurized. After desulfurization, the slag is cleaned. S: 0.0020%;
[0083] S2. The nickel plate is put into the furnace together with the steel scrap, and the charging amount is 19 tons, of which the nickel plate adding amount is 14 tons;
[0084] S3. Perform slag dumping operation after converter slag splashing, slag dumping and slag remaining, 2 tons of slag remaining, after slag dumping, scrap steel with regular shape, no impurities and no oxidation ...
