Advanced Composite Silica Ramming Material refractory cement  

Induction furnace for melting copper "advanced composite silica ramming material. Jinniu Refractory Factory is the production of copper processing copper melting furnace lining refractory materials professional manufacturers. The second generation of GYDL, the third generation of GGD series silicon lining material factory, the majority of users of the support and love, has sold hundreds of domestic and foreign.
Second, the third generation silicon lining material is composed of silica sand and binder, boric acid, the main ingredients and mineral composition is relatively simple. By practice, the simple use of the siliceous material found in any case, changing the proportion, lining life is still not ideal. Because the melting of copper and copper alloy has reached 1180 - 1250 C or higher temperature, and the temperature of the molten metal melt ditch sometimes than metal melt inside the furnace more than 200 degrees, namely the actual lining bearing temperature has reached 1500 to 1550 degrees Celsius, while the sand load softening temperature only 1620 - 1640 degrees. So it is close to the actual bearing temperature and lining. While the main component of its SiO Two It is a multi crystalline mineral material at high temperature, the main crystal of its ingredients with low melting point material, thus contributing to premature glass phase. The refractoriness under load was greatly reduced, and the alpha quartz into alpha tridymite volume expansion of +16%, the internal structure of the lining and loose lining is an important reason for body damage. Only the alpha tridymite temperature controlled at 1470 DEG C, can remain stable; while the temperature is close to or equal to the working lining load softening temperature, the volume from expansion to contraction of -0.9%. Alpha tridymite is very unstable, in the transformation of alpha quartz crystal and crystal glass, the heat generated a lot of stress in the furnace lining and finally cracks and cracking, spalling, copper water seeping into the lining in a short period of time will burn, stone hearth furnace leakage, resulting in scrap lining.
In addition, the melting point of 588 DEG C boric acid, is a kind of low melting point compounds used as silica sand binder, but easy to reduce the sand resistance and easy to lose high adhesive performance, easy to produce crack over sintering sintering layer.

Taurus Refractory ramming mass Factory mainly engaged in professional manufacturer of development, production and sales of the refractory mixture such as melting copper, aluminum and zinc furnace lining. And supply castable refractory for copper smelting, ramming mass for molten copper,fire clay,refractory mortar, refractory cement ,refractory mixture, refractory concrete and silica sand for copper smelting.
