Refractory for non-ferrous alloy is one of the main products of Sino-Foundry Refractory(Jiangsu) Co.,Ltd.with good Wholesale Price and quality, Factory direct sales are the cheape.Our company is a professional supplier and manufacturers,with various products For sale. SIL-RAM 220Cu is silicon oxide based dry ramming refractory material for coreless induction furnaces to melt copper alloys. It can be used in continuous or discontinuous smelting production conditions. SIL-RAM 220Cu uses high quality and high purity quartz sand as the main raw material, and adds a higher proportion of fused quartz sand to make it have excellent volume stability. By strictly controlling the particle size distribution and the amount of binder, it can effectively resist the molten copper erosion, flush and penetration, meanwhile the backing maintains a good loose layer of the backing to improve the safety performance of the overall lining.
