Refractory material can be divided into acid refractory, neutral refractory and alkaline refractory according to chemical properties. Silicon brick is an acid refractory, mainly composed of scale quartz, square quartz and a small amount of residual quartz and glass phase. Silicon brick sales have a good ability to resist acid slag erosion, softening temperature up to 1640 ~ 1670℃, under high temperature for a long time use volume more stable.
RS group can provide suitable refractory materials according to the functional requirements of kilns, so that they can play a full role and build stable and durable kilns. Silicon brick is a kind of high quality refractory products, high quality, safe and reliable use, mainly used in coke oven, iron furnace and glass kiln furnace.
Generally speaking, the silicon bricks sales is made up of quartz, square quartz and a small amount of residual quartz and glass phase. It has good resistance to acid slag erosion. Softening temperature under load is up to 1640-1670℃, The volume is stable under high temperature and the product is of high quality.
Silicon brick sales silica content in more than 94%, true density of 2.35g/cm3, with excellent acid slag erosion resistance, with high temperature strength, long-term use at high temperature without deformation. The series of refractory bricks are slowly fired at 1350~1430℃ under reductive atmosphere. When heated to 1450℃, there is a total volume expansion of 1.5~2.2%. This residual expansion will make the cut joints close together, so as to ensure good air tightness and structural strength of the masonry body.
The silicon bricks sales is mainly used for the partition wall of coking oven’s carbonization chamber and combustion chamber, the regenerator of steelmaking open hearth furnace and slag chamber, the soaking furnace, the refractories of glass melting kiln and the firing kiln of ceramics and other kiln furnaces and other bearing parts. Also used for high temperature bearing parts of hot air furnace and acid open hearth furnace top.
RS group are committed to the production of high quality, the use of safe, stable and reliable refractory products, for the majority of customers to provide quality, comprehensive service, sincerely welcome customers to come to consult, procurement refractory material, we will serve you wholeheartedly.
