White brick are adopting superior material, with process by special arc furnace forming it. nearly no suffer from electrode
refractory manufacturer Refractory burner block white brick Fused cast AZS 1711 for glass industry
1.AZS block has passed ISO 2.erosion-resistance to glass metal 3.low pollution
1.Strong glass corrosion resistance and high thermal shack stability.
2.Good RUL,wear-resistance,dregs-resistance and alkali corrosion resistance.
3.The products are adopting superior material, with process by special arc furnace forming it. This fuse cast technology got nearly no suffer from electrode pollution.
According to above,they can be used at parts where chemical erosion is serious and temperature changes frequently, can be widely used in the lining of glass furnace,the chemical industrials,metallurgical furnace
Our company can produce serious specification fused cast 33#,36#,41#AZS refractory block for glass furnace ,and its output is over 5000tons per year. In the enormous working premises—more than 6600square meters, there are one 5tons outside cooling electric arc furnace, high-power transformer, thaw craft with computer control system and internal advanced fused cast refractory umeral caontrol grinding equipments according to its body producing ability.
erosion-resistance to glass metal
Fused Cast AZS refractory are the most widely used materials both in glass contact and superstructure of glass melting furnaces.
