基于深脱硫磷预处理的球墨铸铁水冶炼方法
The converter process, which combines oxidation slag formation with deep purification using composite solvents, has solved the problems of high raw material costs and difficulty in controlling composition in the production of ductile iron. This has enabled the efficient production of high-purity ductile iron, improving product performance and process economy.

AI Technical Summary
Existing methods for producing ductile iron rely on scarce and expensive ore resources or high-cost scrap steel, resulting in high raw material costs, unstable supply, long process flow, and difficulty in controlling composition. They also cannot effectively remove sulfur, phosphorus, and anti-graphitizing elements, thus affecting product performance.
By employing an oxidation slag-making and composite solvent deep purification method, sulfur, phosphorus, and anti-graphitizing elements are deeply removed through high-alkalinity oxidation and specific composite solvents in a single converter process, resulting in high-purity ductile iron raw materials.
It has enabled efficient and stable production of high-purity ductile iron, simplified the process, reduced energy consumption and emissions, improved product performance and production flexibility, and reduced overall costs.
