Dry lining refractory cement gradation

The principle of maximum packing density gradation and sphere like particles of dry lining refractory cement, lining is obtained as dense, rational particle grade is very necessary. Large particles lining in quartz sand plays a role in skeleton, an important contribution to the strength and density, but its size should be appropriate, because the change is too large the crystal type caused by volume expansion, the lining body is easy to crack.The critical particle size is determined by the size of the dry lining refractory cement is decided by the thickness of the lining, the lining thickness is the critical size can be larger. Practice shows that the general large particles with 3~4mm is appropriate.
Fine powder of lining material in sintering to promote, because the increase in new surface in the crushing process, the specific surface area increased, the activity increased under high temperature, easy to transfer, and the formation of impurities in liquid phase and promote sintering. Domestic induction furnace of quartz sand particle size distribution is not uniform, which also makes the lining life are large.

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.
