Dab tsi yog qhov txawv ntawm cov cement castables thiab cov tsoos castables?
Muaj qhov sib txawv loj ntawm cov cement castables qis thiab cov tsoos castables, feem ntau yog qhov sib txawv ntawm nruab nrab lub zog thiab lub zog lig. Cov tsoos castables muaj lub zog nruab nrab lub sij hawm tsis zoo, thaum cov cement castables qis dua zoo dua li cov tsoos.refractory castables. Tsis tsuas yog cov cement ntau npaum li cas qis, cov ntsiab lus calcium tsawg, thiab tseem siv ultra-nplua hmoov tshuab los faib cov castable particles nyob rau hauv ib tug tsim nyog proportions, thiab lub lig-theem zog thiab nruab nrab lub sij hawm lub zog ntawm lub castable yog ntxiv txhim kho.
1. Txheej txheem cej luam ntawm high-strength castables
Piv nrog cov tsoos refractator casterables, cov txiv qaub ua kom muaj kev kub ntxhov ntau, porosity tsawg, thiab siab dua chav ntsuas kub kho lub zog; lawv kuj muaj qhov ntim zoo ruaj khov thiab muaj qhov ntim me me tom qab ziab thiab calcining. Cov khoom siv muaj zog qis-cement hauv cov cement castables yog tsim nrog cov calcium aluminate cov cement ua tus neeg sawv cev khi. Qhov kev pabcuam kub ntawm high-strength castables ncav cuag 1600 degree thiab muaj kev hnav zoo thaum kub kub. High-strength, low-cement castables yog haum rau siv nyob rau hauv ntau yam kiln linings nrog kub kub thiab muaj zog corrosiveness.
2. Kev piav qhia ntawm cov cement castables qis
Cov khoom siv qis-cement siv fused dawb corundum ua aggregate hu ua low-cement corundum castable. Cov khoom siv corundum-raws li qis-cement muaj lub zog txhua yam, tiv taus yaig thiab puas, thiab qhov kev pabcuam kub ncav cuag 1700 degree. , Tsawg cement corundum castable yog tsim rau siv nyob rau hauv loj cement kiln qhov ncauj, ntau lub tog raj kheej txias lub luj tshib thiab lwm yam hauv ob sab phlu qhov chaw qhov kub siab tshaj 1400 degree thiab qhov twg cuam tshuam yaig hnyav. Thiab nws yog tsim rau siv nyob rau hauv txhua qhov chaw ntawm lub qhov cub hauv ob sab phlu tshaj 1400 degree.
3. Kev ua tau zoo ib txwm tsis zoo li cov cement castables tsawg
Cov tsoos refractory castables yog ua los ntawm refractory hais thiab hmoov, nrog rau siab alumina cement. Cov particle gradation ntawm qhov sib sau ua ke tsis zoo li cov khoom siv cement tsawg. Cov cement hais kuj coarser, thiab qhov feem ntawm cov cement ntxiv yog loj, thiab cov dej ntxiv thaum lub sij hawm tsim kho kuj loj. Tsis tas li ntawd, cov cement ntau ntau thiab cov khoom tsis raug cais tawm, yog li cov khoom siv cement tsis tuaj yeem ua kom muaj dej txaus, tshwj xeeb tshaj yog nyob rau ntawm qhov kub ntawm 800 degree, nws yeej tsis muaj zog, yog li kev ua haujlwm ntawm cov tsoos castables tsis zoo li. low-cement castables.
