Refractory Furnace Cement Manufacturer

Refractory cement is also called high-temperature cement. The refractory degree of refractory cement is not less than 1580℃. Refractory cement is a clinker made by calcining bauxite and limestone as the main component, with calcium sulfate as the main component and an alumina content of 50%, and then ground into fine powder to make a fire-resistant hydraulic cementitious material. It can be used as a lining for cement rotary and other industrial kilns.

Types of refractory fire cement

Reforse tsementini alyuminate orqali ajratish mumkin, Kaltsiyning pastligi oshishga chidamli tsement, kaltsiy magniy alyuminatin tsement, and dolomite refractory cement according to different compositions.

Application of high-temperature cement

The main application areas of refractory cement are continuous high-temperature industries, such as steel smelting, glass production, cement production, furnace bodies, va boshqalar. Refractory cement is widely used in these fields because it can withstand harsh working environment conditions such as sustained high temperatures, high pressures, chemical corrosion, va boshqalar.

Things to note when baking refractory cement furnace lining

(1) At the normal temperature of 350°C, local bursting is most likely to occur, Shunday qilib, sekin pishirish uchun alohida e'tibor berilishi kerak. If a large amount of steam still emerges after insulation at 350°C, Isitish darajasi hali sekinlashishi kerak.
(2) Under conditions where ventilation is poor and water vapor cannot be easily discharged, the heat preservation time should be appropriately extended.
(3) Og'ir moy bilan pishirilganda, be careful not to spray heavy oil on the surface of the furnace lining to prevent local bursting.
(4) O't o'chirilganda, direct contact with the flame often causes excessive local temperature rise and should be protected.
(5) The newly poured refractory cement must wait at least 3 days before baking.
(6) The cooling of the refractory cement furnace lining should also be slow and forced ventilation should be avoided.

Furnace cement packaging and shipping

Refractory cement is packaged in 25kg bags, which can also be customized, and then packaged in ton bags to facilitate transportation and transshipment.
