为改善低磷钢和普钢熔炼的经济性,日本住友金属鹿岛厂研究了一种新的铁水脱磷工艺。 1 简单精炼法(SRP) 新的SRP法有如下内容: (1)用2座容量为250t的顶底复吹转炉作反应器,其中1座作脱磷,另1座作脱碳,完成一个两段式逆流罐操作过程。 (2)从脱碳炉获得的低P_2O_5的块渣,用作脱磷炉的脱磷剂,这可使石灰的总消耗
In order to improve the economy of low-phosphorus steel and general steel smelting, Japan’s Sumitomo Metal Kashima plant to study a new hot metal dephosphorization process. A simple refining method (SRP) The new SRP method has the following contents: (1) with 2 capacity of 250t top and bottom blowing converter as a reactor, one for dephosphorization, and the other for decarburization to complete a Two-stage countercurrent tank operation. (2) Slag of low P 2 O 5 obtained from the decarburizing furnace is used as a dephosphorizing agent for the dephosphorizing furnace, which makes the total consumption of lime
