重型锻件的质量特性是由材料性能和材质均匀性来决定的,而生产优质锻造钢锭的先决条件是采用相应的冶炼和铸造工艺。例如,将钢中的含磷量和含硫量降低到最低限度就能够显著地改善材料性能。在金属液凝固期间,由于物理和冶金现象,在惯常生产的钢锭中就产生不均匀性或偏析。这些偏析的避免或减小也只能通过干预钢锭凝固过程才能达到。Bhler电渣补注方法是一个强烈影响钢锭凝固过程的方法。B.E.S.T.(Bhler电渣补注)法的特点就是在钢锭浇注以后,将热能输入液态的锭体之中。输入钢锭冒口
The quality characteristics of heavy forgings are dictated by material properties and material homogeneity, and the prerequisite for the production of high quality forged ingots is the use of appropriate smelting and casting processes. For example, minimizing the amount of phosphorus and sulfur in the steel can significantly improve material properties. During the solidification of molten metal, due to physical and metallurgical phenomena, inhomogeneities or segregations occur in the customary production of ingots. Avoidance or reduction of these segregations can only be achieved by interfering with the ingot solidification process. The Bhler Electroslag Replenishment method is a method that strongly affects the ingot solidification process. B.E.S.T. (Bhler electroslag replenishment) method is characterized by pouring the ingot, the heat into the liquid into the ingot. Enter the steel riser
