preparation example Construction
[0023] According to the present invention, the preparation method of the rare earth alloy steel plate may include the following steps:
[0024] (1) Metal material smelting: Pretreatment of molten iron is followed by converter smelting and deoxidation alloying. Among them, the composition of outbound molten steel controlled by converter smelting and deoxidation alloying includes: C, Si, Mn, Mo, Cr, P and S , and based on the total weight of the molten steel, P≤0.03% by weight and S≤0.02% by weight; the temperature of the outbound molten steel for converter smelting and deoxidation alloying is 1500-1540°C;
[0025] (2) Microalloying treatment: Refining the outbound molten steel obtained in step (1) in an LF furnace; the temperature of the outbound molten steel in the LF furnace is 1520-1560°C;
[0026] Wherein, through the joint control of step (1) and step (2), the molten steel out of the LF furnace contains: 0.1-1% by weight of C, 0.4-0.7% by weight of Si, 0.4-0.65% by weight ...

[0041] This preparation example is used to illustrate the preparation method of the rare earth alloy steel plate provided by the present invention
[0042] (1) Metal material smelting: the molten iron and steel scrap after desulfurization pretreatment are used for converter smelting, and the sulfur content in the molten iron entering the furnace is controlled to be ≤0.02% by weight. In the early stage of blowing, slag is dissolved early, lime is added in an amount of 50-70kg per ton of steel, and slag-making ore is added in an amount of 12-20kg. After the molten steel is completely melted, ferromanganese, ferrosilicon and ferromolybdenum are added, and after complete deoxidation Tapping: Controlled converter smelting and deoxidation alloying outbound molten steel components include: C, Si, Mn, Mo, Cr, P and S, and based on the total weight of molten steel, P≤0.03% by weight and S≤ 0.02% by weight; the outbound molten steel temperature for converter smelting and deoxidation all...

[0050] (1) Metal material smelting: the molten iron and steel scrap after desulfurization pretreatment are used for converter smelting, and the sulfur content in the molten iron entering the furnace is controlled to be ≤0.02% by weight. In the early stage of blowing, the slag is removed, lime is added in an amount of 70kg per ton of steel, and slag-making ore is added in an amount of 15kg. After the molten steel is completely melted, ferromanganese, ferrosilicon and ferromolybdenum are added, and the steel is tapped after complete deoxidation; control Outbound molten steel components for converter smelting and deoxidation alloying include: C, Si, Mn, Mo, Cr, P and S, and based on the total weight of molten steel, P≤0.03% by weight and S≤0.02% by weight; The outbound molten steel temperature for converter smelting and deoxidation a...
