Silicon carbide castable

Kev sib xyaw yog muab faib ua kev sib xyaw ua ke thiab kev sib xyaw ua ke.Tam sim no, cov khoom siv dag zog los yog mortar mixers yog siv rau hauv kev lag luam los sib xyaw cov ntaub ntawv, thiab kev sib xyaw ntawm phau ntawv tsis siv Cov Khoom Siv thiab cov cuab yeej: cov khoom siv dag zog los yog cov khib nyiab, cov thoob, nplai, vibrators, cuab yeej shovels, trolleys, thiab lwm yam.

Kev siv dej hauv kev tsim kho yog ua raws li cov dej siv tau teev tseg hauv daim ntawv tshuaj ntsuam xyuas zoo ntawm cov khoom lag luam, thiab nruj me ntsis ua raws li cov qauv kom ua tiav qhov ntsuas qhov tseeb.

Mixing: Sib tov qhuav ua ntej thiab ces ntub.Muab cov khoom ntim rau hauv lub tov khoom thiab qhuav rau 1-3 feeb nyob rau hauv qhov kev txiav txim ntawm lub hnab loj ua ntej thiab ces lub hnab me me kom nws sib npaug.Qhov hnyav ntawm txhua qhov sib xyaw yog txiav txim siab raws li cov tshuab thiab kev tsim kho ntim;Raws li qhov hnyav ntawm cov khoom siv, cov dej xav tau rau txhua qhov sib xyaw yog ntsuas kom raug raws li cov dej tau teev tseg, ntxiv rau cov khoom sib xyaw ua ke qhuav, thiab tag nrho stirred.Lub sij hawm tsis pub tsawg tshaj 3min, kom nws muaj qhov haum fluidity, thiab tom qab ntawd cov khoom tuaj yeem tso tawm rau kev nchuav.

Ua ntej cov khoom siv pouring yog tsim, nws yog tsim nyog los xyuas seb lub anchors yog ruaj khov welded, thiab kub-resistant rau tes yuav tsum tau siv rau qhov chaw siab tshaj 500C.Qhov saum npoo ntawm lub thauj tog rau nkoj yuav tsum tau pleev xim nrog 0. 5-1mm tuab xim los yog qhwv nrog yas daim kab xev kom tsis txhob muaj zog expansion tom qab cua sov thiab tshem tawm cov khib nyiab hauv pwm.

Qhov sib xyaw castable tshiab yuav tsum tau nchuav sai, feem ntau hauv 20 feeb.Muab cov sib xyaw castable rau hauv pwm, thiab ntxig lub vibrator rau hauv vibrator hauv lub sijhawm, thiab lub vibrator yuav tsum zoo ib yam.Thaum lub npoo ntawm lub castable yog slurried, npuas yog tawm.Thaum lub npoo yog slurried, lub vibrating pas nrig yog txav, thiab txav ceev yog 1-2m / min.Thaum lub vibrating pas nrig yog rub tawm, qhov ceev yog qeeb.

Ua ntej solidification tiav tom qab pouring, qhov chaw kub yuav tsum tau khaws cia siab tshaj 10C (10-30.C).Yog tias qhov chaw kub qis dua 0'C, cov cua kub sib xws thiab kev txuag hluav taws xob yuav tsum tau ua, txwv tsis pub nws yuav ua rau retardation thiab ua rau cov khoom lag luam degradation.

Cov cuab yeej tseem ceeb siv yog polyethylene yas zaj duab xis, straw hnab, thiab lwm yam. Ambient kub yuav tsum tau thiab tswj: qhov kub ntawm lub casting lub cev yog zoo dua li ntawm 15-35C Yog hais tias qhov kub tshaj qhov kub ntawm no ntau yam, coj mus rau cua sov los yog txias ntsuas, txwv tsis pub. kev ua haujlwm ntawm cov khoom yuav raug txo.

Tom qab cov castable yog hardened, nws yog ib qhov tsim nyog yuav tsum tam sim ntawd npog lub nto ntawm lub tsev siv lub cev nrog polyethylene yas zaj duab xis, thiab thercover nws nrog ib tug ntub straw hnab los tiv thaiv dej evaporation thiab txhawb cov cement ua kom tom qab hardening, nws yog txwv tsis pub mus tuav thiab vibrate nyob rau hauv ib tug. hnub.Raws li qhov teeb meem hardening, nws tuaj yeem demolded tom qab 24-30 teev ntawm hardening.

Tom qab demoulding, nws yuav tsum tau khaws cia rau ob hnub raws li xav tau, thiab polyethylene yas zaj duab xis thiab lub hnab ntim quav ntub yuav tsum tau ntxiv thaum lub sijhawm tu.Tom qab peb hnub ntawm kev kho, tshem cov yas zaj duab xis thiab straw hnab.Cia lub cev tawv kom qhuav ib txwm nyob hauv huab cua rau ib hnub ua ntej ci.

Ci yog qhov tseem ceeb kawg txuas hauv kev siv cov castables.Txij li thaum lub cev casting yog qhov ntom ntom, nws yog qhov txwv tsis pub kom sov sai heev thaum lub sij hawm ci, txwv tsis pub nws yuav ua rau muaj kev sib tsoo.
