Product Description

Sillimanite Fire Brick

Description
       Sillimanite and mullite refractories are characterized by their high refractoriness,good thermal stability and resistance to corrosion and erosion of glass liquid and hence have less pollution to glass liquid.So they are the  most common refractories used for the feeder machine and tube drawing machine in domestic and foreign glass industries to promote productivity obviously.On the list of products there are feeder channel brick, pot spout, mandrel,spout,orifice ring,stirrer,needle,feeder sleeve, skimmer block,damper brick,spout cover,burner block, lintel,cover plate brick,muffle furnace brick etc. altogether about one hundred varieties with different sizes. Resintered fused mullite bricks and corundum bricks are superior in resistance creep and applied to the superstructure of the borosilicate glass , fiber glass furnace etc.
