2, Characteristics:
1) The product has high purity and high quartz content
2) Good resistance to hot metal erosion
3) It has good resistance to quenching and heating
4) Stable performance at high temperature
5) Low consumption rate
3, Application: it is mainly used for melting gray iron, ductile iron and alloy steel in foundry
4,Product storage: the product is packed in waterproof 25kg bags. If the product cannot be used in time, it must be stored in a dry, ventilated and moisture-proof warehouse at - 40 ℃ ~ 40 ℃ to prevent the product from being wet by rain and snow. Otherwise, the product is easy to agglomerate and cannot be used.
5,Construction method: Ramming construction
6,Product maintenance: after the construction, in order to prevent the product from drying and cracking, spray water mist twice a day, and bake after 2 days of natural drying and maintenance
7,Refer to baking temperature rise curve
