小方坯连铸保护渣

Slag for Continuous Casting Square Billet Steel Slab

（预熔型中空颗粒系列连铸结晶器保护渣）

(Pre-melting hollow grain series)

1、 产品特点：为了实现保护浇注，改进原结晶器用菜油润滑工艺，实现较好的铸坯表面质量。我公司配置了粉状、实心颗粒、中空颗粒各种渣型，供用各种用户需求。由于熔融特性好、产品质量稳定，适宜连铸条件较宽（拉速可达3米以上）。具有铸坯表面光洁平整、振痕较浅、无结壳、无渣条等优点。

Product Description: To protect the teeming so as to improve the surface quality of slab, we better the technique of rapeseed oil-lubricating mould. We provide powdery, solid-grain, hollow-grain slag to meet customers’ different needs. It has good melting characteristics and stable quality, and suits for various continuous casting conditions (casting speed can be up to over 3m), with merits of smooth and bright surface, light crease, skull-free and slag-free.
