Tsawg cement castables yog ib hom refractory castable nrog qhov kev pabcuam siab tshaj 1550 ℃, uas siv cov cement aluminate raws li nws cov ntaub ntawv, uas cov nyiaj CaO tsawg dua 2.5%. Refractory tsawg cement castable muaj pes tsawg leeg feem ntau muaj refractory aggregate, refractory hmoov thiab dej. Piv nrog rau cov tsoos refractory castable, tsawg cement refractory castable muaj cov kev ua tau zoo xws li cov cement tsawg, tsis muaj porosity, zoo ntim stability thiab siab txias curing-lub zog. Thiab kuj tsis tshua muaj cement castable ceev yog siab dua li lwm yam refractory castables.
Tsawg cement castable yog castable refractory uas yog ua los ntawm ultrafine hmoov, aluminate cement thiab ib co admixtures. Tsis tas li ntawd, tus nqi ntawm cov khoom sib xyaw no tuaj yeem cuam tshuam nws txoj haujlwm. Raws li rau nws cov dej npaum li cas, muab qhov kev lees paub yooj yim ntawm cov khoom sib xyaw, ntxiv cov dej me me tuaj yeem txo qhov porosity thiab txhim kho lub zog. Tsis tshua muaj MAAs refractory castable muaj qhov zoo ntawm me ntsis nqi ntawm cov dej, kev kub ceev thiab siab zog, uas yog vim li cas hais tias qhov no refractory khoom yog dav siv nyob rau hauv ntau lub teb thiab ntau yam furnaces thiab kilns.
High Refractory Kub thiab muaj zog thiab siab tiv thaiv - Slag Corrosion Resistance.
Tsawg Porosity thiab High Bulk Density. Thaum lub sij hawm tsim kho, tsuas yog 1/3 ~ 1/2 tus nqi ntawm cov dej rau cov tsoos castable yuav muab ntxiv rau hauv nws.
Ua kom muaj zog nrog kev txhim kho qhov kub thiab txias ntawm kev kho cua sov tom qab Casting rau hauv cov duab: Nrog kev kho kom zoo ntawm cov castable loj, nws tuaj yeem muab sib xyaw rau hauv nws tus kheej ntws castable thiab pumped pouring khoom.

Tsawg cement rwb thaiv tsev castable yog dav siv nyob rau hauv ntau industries xws li metallurgical kev lag luam, petrochemical kev lag luam, fais fab nroj tsuag, kev tsim kho teb thiab lwm yam lag luam. Thiab kuj Low cement refractory castable yuav siv tau rau cov furnaces thiab boilers nyob rau hauv ntau qhov chaw raws li ntau yam muaj pes tsawg leeg. Piv txwv li, av nplaum thiab siab alumina tsawg cement refractory castable ob leeg siv tau rau hauv ob sab phlu ntawm cov cua sov rauv, soaking rauv thiab lwm yam cua sov rauv.
RS refractory Hoobkas yog cov kws tshaj lij uas tsis tshua muaj cov cement thaiv castable uas tau tsim nyob rau hauv thaum ntxov 90s ntawm nees nkaum caug xyoo. RS refractory Hoobkas tau tshwj xeeb hauv qis cement castables rau ntau tshaj 20 xyoo. Yog tias koj muaj qee qhov kev thov ntawm refractory low cement castable, lossis muaj qee cov lus nug ntawm refractory low cement castable txog lub cev thiab tshuaj ntsuas ntsuas, thov hu rau peb dawb. thiab Rs refractory Hoobkas raws li cov kws tshaj lij qis cement refractory castable chaw tsim tshuaj paus hauv Suav teb, muaj qee qhov kev sib tw zoo li hauv qab no:
