Tsawg cement refractory castables yog tsim los siv CA-70 calcium aluminate cement raws li cov ntaub ntawv, ua ke nrog refractory aggregates, hmoov, thiab additives nyob rau hauv ua tib zoo tswj proportions. Tom qab dej ntxiv, qhov sib tov yog mechanically tov, cam khwb cia, thiab kho kom tsim ib tug ntom monolithic refractory hauv ob sab phlu.
Cov castables no yog tus cwj pwm los ntawm kev ua kom tawv nqaij sai, lub zog siab, tus nqi qis, cov khoom siv tau yooj yim, thiab kev tsim kho yooj yim. Thaum tsim nrog cov ntaub ntawv aluminosilicate, lawv kuj muaj qee qhov kev tiv thaiv rau sulfate nres.
Qhov kev pab cuam kub ntawm hom castable no yog nyob ib ncig ntawm 1400 degree, thiab nws yog feem ntau siv nyob rau hauv industrial furnaces xws li cua sov rauv, boilers, thiab petrochemical processing furnaces. Nws kuj tau ua tiav tiav hauv qhov qis- cov khoom siv thermal thermal hauv cov tshuab metallurgical.
Qhov siab tshaj plaws kev pabcuam kub ntawm cov cement refractory castables tuaj yeem ncav cuag li 1500 degree, ua tau raws li qhov yuav tsum tau muaj ntawm ntau qhov chaw ua haujlwm dav dav. Thaum rhuab saum toj no txog 1200 degree, sintering tshwm sim vim cov kua theem nce, uas ua rau tsim ib daim ntawv cog lus ceramic. Yog li ntawd, lub zog ntawm castable nce nrog nce kub, thaum tuav lub siab load softening kub thiab zoo refractoriness.
