In recent years, Phosphate bonded high alumina brick with the strict requirements of refractory materials in kiln engineering, this series of high alumina bricks have been continuously upgraded. Phosphate bonded high alumina brick advantage outstanding, good quality, reasonable price, welcome to consult.
In the continuous research and upgrading, we phosphate bonded high alumina brick by adding bluestone to increase the softening temperature under load, and also add active silica raw materials. The softening temperature under load was further increased by the reaction of activated silica and alumina at high temperature.
Phosphate bonded high alumina brick advantage is remarkable, adding aluminum dihydrogen phosphate, this method of sintering, not only high strength, in the white ash kiln burning belt use effect is particularly good.
After adding silicon carbide or silicon metal, the softening temperature of the load can be raised by the one-time expansion and secondary expansion of the raw material after heating. The performance of refractory brick is improved effectively and the economic benefit is remarkable.
In recent years, phosphate brick is made again have the compound brick of light weight layer. This not only improves the heat insulation performance, but also reduces the heat dissipation and heat consumption of the kiln.
With the continuous progress of refractory production technology, the properties of phosphate bonded high alumina brick not only extend the life of kiln lining. Especially the phosphate bonded brick used in white ash kiln, not only good performance, but also the lime activity is good.
This series of refractory high alumina brick is made of phosphate as the binder through high pressure molding and medium temperature treatment. Phosphate bonded high alumina brick advantage has obvious, such as high strength, good wear-resistance, good anti-spalling, and strong resistance to alkaline slag erosion. It is widely used in preheating zone and decomposition zone of cement kiln.
