High-quality silica bricks for glass kilns have the characteristics of high silicon oxide content and low melting index. High-quality silica bricks for glass kilns are mainly used for the crown top, breast wall hanging wall, small furnace, and other upper structures of glass kilns and the crown of the regenerator. Rongsheng refractory material manufacturer can provide customized silica bricks for glass kilns according to the actual working conditions of the glass kiln. This can extend the service life of the glass kiln lining and save production costs for enterprises. Contact Rongsheng for free samples and quotes.
Physical and chemical indicators of high-quality silica bricks for glass kilns
High-quality silica bricks for glass kilns refer to the standard JC/T615-1996 and are divided into three grades according to the unit weight of the bricks: XBG-96, ZBG-96, and DBG-96. Physical and chemical indicators of high-quality silica bricks for glass kilns in Rongsheng.
