摘要:

为降低中间包涂抹料的原料成本,以镁橄榄石颗粒为骨料,研究了以1~3 mm镁橄榄石颗粒料部分替代镁砂颗粒对中间包涂抹料性能的影响。结果表明:相对镁质中间包涂抹料而言,以10%镁橄榄石颗粒(1~3 mm)部分替代镁砂颗粒研制的涂抹料产品更适合作为中间包镁质涂抹料的替代品。添加5%废镁铬砖颗粒的试样其强度变化不明显,高温性能有所下降。

Abstract:

In order to reduce the raw material cost of tundish coating, the effect of 1~3 mm forsterite particles partly replacing magnesia particles on the properties of tundish coating was studied by using forsterite particles as aggregate.The results showd that the coating prepared with 10% forsterite particles (1 ~3 mm) instead of magnesia particles is more suitable as a substitute for magnesia coating in tundish.The strength of the samples with 5% waste magnesia-chrome brick particles changed little, and the high-temperature properties decreased.
