Steel fiber reinforced castables greatly enhance the thermal shock stability of wear-resistant castables by introducing heat-resistant steel fibers. Cov khoom muaj siab hnav tsis kam tiv, thermal poob siab thiab ntim ruaj khov.
Siv cov fiber ntau siv fiber cuam tshuam tau siv rau ntau qhov chaw xws li txhuas melting ruraces thiab muaj cov lus pob. Ntawm lawv, Corundum Hlau Fiber hnav-resistant caslesables yog ua los ntawm bauxite clinker zoo li cov khoom siv sib xyaw ua ke, cov khoom sib xyaw ua ke thiab cov hlau stainless-resistant fibers. Corundum Hlau Fiber ntau Kastable Nqe Corundum Cibrundles Ntxiv cov hlau stainless fibers kom nce lub zog
Cov khoom siv ua kom muaj hlau ua hluav taws xob yog cov khoom siv hluav taws xob tsim nyog los ntawm kev ntxiv cov roj cua sov uas tsim nyog los ntawm clinker colundum ua aggregate thiab hmoov. Lawv muaj cov yam ntxwv ntawm kev tiv thaiv sai sai, cua sov sai, muaj zog, kub kev poob siab, thiab coj tsis kam.
Ntxiv nrog rau cov pa hluav taws kub ua rau muaj cov khoom sib txawv ntawm cov khoom siv kub, thiab nres, uas ua rau muaj kev puas tsuaj ntawm cov cua sov phab ntsa. Nyob rau tib lub sijhawm, vim qhov sib ntxiv ntawm cov fiber steel, lub zog tag nrho ntawm cov cua sov phab ntsa yog txhim kho tom qab cov khoom cam.
Cov khoom lag luam
Cov tshav kub-resistant steel fiber siv nyob rau hauv cov fiber ntau fiber cuam tshuam txog cov khoom siv sib txawv ntawm lub nkoj, nrog ib qho ntev ntawm 20 hli, 25mm thiab 35mm; Cov qib ntawm tshav kub-resistant steel fibers tau muab faib ua 330, 346 thiab 4cr15ni2, 1cr15si2 thiab 1cr18si2. Qhov kev sib ntxiv ntawm 1% rau 5% kub-resistant steel fiber ntau tuaj yeem ua tiav cov nyhuv ntawm kev ntxiv dag zog thiab ua kom tawv.
Cov tshav kub-resistant steel fiber siv nyob rau hauv cov khoom siv fiber ntau ntxiv uas tau raug xaiv los ua cov khoom siv thermal thiab nws cov khoom siv tau tsim nyog yuav tsum txiav txim siab. Nws cov txheej txheem npaj: thawj hnyav hnyav lub refractory, hmoov, binder thiab admixture, sib tov qhuav rau 1 feeb; Tom qab ntawd ntxiv dej rau ntub tov sib xyaw, thiab tusyees txau cov hlau fiber ntau rau hauv cov khoom tsis muaj agglomeration; Thaum kawg sib tov rau 1 feeb ua ntej tso tawm. Lub sijhawm sib xyaw tag nrho yuav tsum tsis pub tsawg tshaj 5 feeb. Thaum siv tus pas nrig Vibrating rau molding, qhov kev co yuav tsum yog staggered los ua kom cov hlau fiber ntau cov lus qhia tsim nyog, uas tuaj yeem txhim kho kev ua tau zoo.
Cov kev ua tau zoo ntawm cov fiber ntau siv fiber ntau ntxiv cov kev sim ntawm nruab nrab thiab qis dua tshuab hluav taws xob, yog kev txhim kho hluav taws xob nrog cov uas tsis muaj cov hlau fiber ntau. Txawm li cas los xij, hais txog 1400 degree kev kub siab flexural muaj zog thiab sleag tiv taus, cov hlau refractory castables tsis zoo li refractory castability tsis muaj steel fiber ntau.
