Khoom piav qhia
Raws li hom cementing tus neeg sawv cev, cov pa castable refractory tuaj yeem muab faib ua alumina cement refractory castables, aluminium -60 cement refractory castables, tsawg calcium aluminate cement castables thiab ntshiab calcium aluminate cement refractory castables. Aluminium ntsev cement refractory castables muaj cov yam ntxwv ntawm kev tawv tawv sai, siab zog, zoo thermal shock stability, thiab siab refractoriness. Yog li ntawd, lawv tau siv dav hauv kev lag luam kilns thiab cov khoom siv thermal hauv metallurgy, petrochemicals, hydropower, tsev cov ntaub ntawv, machinery thiab lwm yam kev lag luam sectors. Hauv kev ua lag luam, nws qhov siab tshaj plaws ua haujlwm kub yog 1400-100 degree, thiab qee qhov tuaj yeem ncav cuag 1800 degree .
Daim ntawv thov ntawm cov pa castable refractory:
◆ Cement kiln
◆ Lub qhov cub cua sov
◆ Recirculating fluidized txaj boiler
◆ Kev lag luam tshuaj thiab kev tsim kho kev lag luam
◆ Tundish hauv ob sab phlu
