Refractories (Refractory material) selection and matching proposal (four) large kiln kiln door cover and cooler formula throat and high temperature high parts of the region (1250 ℃ above), the general anti-stripping or chemically bonded alumina bricks (Special) alumina bricks as a working layer material. But the vault at these sites should normally be calcined alumina bricks, high alumina bricks should not be used in chemical combination. The formula then high pressure coolant temperature zone silicon carbide composite sidewalls should adopt a low brick or cement high-strength refractory castable. Such as where corrosion is not serious, you can use the combination of high aluminum phosphate wear-resistant tiles. Jane coolers lining should be made of high quality wear-resistant materials, including steel fiber reinforced toughened aluminum phosphate binding high wear-resistant tiles. Refractory ramming tamping method using semi-wet state construction refractory mix called refractory ramming. And how much different refractory plastic refractories, refractory mix is ??such a low plastic or no plastic tamping material, is forced to rely on the formation of a dense body tamping refractories manufacturers, and then hardened by heating occurs while baking or roasting obtain certain structural strength. Now tamping method of construction materials, in addition to plastic (wet ramming) and ramming (semi-wet ramming) refractories, is a completely non-plastic ramming. Past refractory ramming materials and varieties, use a wider scope, but because of the construction labor intensity long ramming large refractory wholesale, construction work time, it is difficult to obtain uniform lining of the body as a whole, has gradually been no other construction methods shaped refractories (Refractory material) replaced. Now use this semi-wet state ramming few places. Currently ramming the main varieties are: aluminum - Magnesia ramming mixes, high-alumina (or corundum) - silicon carbide - carbonaceous ramming, basic refractory ramming and zirconium mullite ramming materials.
