Affect of Continuous Casting Process on Cold Rolling and Galvanized Sheet Surface Defect 连铸工艺对冷轧镀锌板表面缺陷的影响
A general problem in protecting the casting ingots by using expanded complex mould casting mold powder is the surface defect that slag deposition can be evolved easily in ingots head. 使用膨胀型复合模铸保护渣保护浇注钢锭,普遍存在的一个问题是容易使钢锭产生头部积渣这一表面缺陷。
The electric-magnetic horizontal continuous casting process is a method of continuous casting by substituting the electric-magnetic force instead of the mould. It can completely solve problems such as the slab surface defect, etc. 水平电磁连铸法是以电磁力代替结晶器进行连铸的方法,它可彻底解决铸坯表面缺陷等问题。
Slab casting with thin wall 、 large area and unprocessed surface is easy to produce warping deformations and surface quality defect, etc. 壁薄、大面积、表面不加工的平板铸件易出现弯曲变形、表面质量不好等问题。
The metal penetrated sand adhering defect often companies in the application of furan resin sand on large size iron casting. The surface quality of castings is affected by this defect and even result in casting rejection. 呋喃树脂砂在大型铸铁件上的应用过程中,经常产生金属渗透性粘砂缺陷,影响铸件表面质量,严重时能导致铸件报废。
The effect of molten steel purity, casting temperature, performance of protecting slag, oscillation and liquid level control of mold in continuous casting on surface defect was studied importantly. 重点阐述了钢水洁净度、浇铸温度、保护渣性能、结晶器振动以及液面控制等连铸工艺对表面质量的影响。
