Muaj qhov sib txawv ntawmqis cement castablesthiab CA-50 castables, tsis tsuas yog nyob rau hauv cov nqe lus ntawm cov txheej txheem, siv kub, siv dej npaum li cas, tab sis kuj muaj ntau yam qhia.
1. Qhov sib txawv ntawm kev tsim kho
Qhov sib txawv ntawm kev tsim kho ntawm qis cement castables thiab CA-50 castables yog cov dej ntxiv. Cov dej ntxiv rau cov cement castables tsawg yog 5-7%, hos cov dej ntxiv rau CA-50 cov ntaub ntawv yog li 15%. Vim muaj cov dej ntau ntxiv rau CA-50 cov ntaub ntawv, kuj tseem muaj ntau qhov pores. Cov ntaub ntawv qis-cement ntxiv dej tsawg dua, muaj qhov ntim ntau dua, thiab muaj cov txheej txheem denser.
Qhov nruab nrab kub lub zog yog qhov txaj muag tshaj plaws ntawm cov castable, vim hais tias ntawm qhov kub thiab txias, lub zog castable, ob lub castables kuj muaj qhov sib txawv loj ntawm qhov kub thiab txias. Qhov qis cement castable yog vim qhov sib ntxiv ntawm silica fume thiab qib siab refractory cement. Qhov no tsis tsuas yog offsets lub ntim shrinkage ntawm lub castable, tab sis kuj nce lub nruab nrab-kub lub zog es tsis txhob yuav txo. Lub zog nruab nrab ntawm qhov kub thiab txias ntawm cov khoom siv CA50 yog qhov tsis muaj zog txaus, thiab lub zog yuav poob qis heev ntawm 800 degree.
2. Qhov sib txawv ntawm qhov kub thiab txias
Lub castable yog lub cev molded, thiab qhov loj ntawm qhov pores ncaj qha cuam tshuam rau kev ua haujlwm ntawm castable. Qhov qis cement castable muaj tsawg dua qhov pores, kev faib tawm ntawm me me capillary pores, thiab zoo corrosion kuj. Tus nqi ntawm qhov pores hauv CA-50 castable ntawm qhov kub ntawm 800 degree Qhov corrosion kuj yog 25% qis dua li cov khoom siv cement tsawg. Tshwj xeeb tshaj yog nyob rau ntawm qhov kub ntawm 1400 degree, cov slag thiab hnav tsis kam ntawm cov ntaub ntawv qis-cement yog siab dua cov ntaub ntawv CA-80. Vim tias cov cement tsawg dua ntxiv rau cov cement castables tsawg, cov ntsiab lus calcium txo. Cov ntsiab lus calcium tsawg ua rau cov khoom siv qis qis, thiab kev siv tom qab siv kuj tseem siab, uas yuav ua rau nws lub neej ua haujlwm zoo.
3. Qhov sib txawv ntawm corrosion kuj
Tom qab ob lub castables no tau qhuav ntawm qhov kub ntawm 1400 degree, qhov flexural tsis kam ntawm cov cement castable yog ob zaug siab dua li ntawm CA-50 castable, thiab cov refractoriness yuav yog 20-100 degree siab dua. uas ntawm CA-50 castable. Yog li, kev siv kub qis dua Cov khoom siv cement yog 100 degree siab dua CA-50 cov khoom. Lub thermal shock tsis kam ntawm ob cov ntaub ntawv no, tom qab lub voj voog dej txias ntawm 1100 degree, cov khoom siv cement qis tau zoo dua thermal shock dua li CA-50 cov khoom, thiab kev yaig kuj txawv li ntawm 25%.
Muaj qhov sib txawv loj ntawm ob lub castables no. Hauv kev tsim khoom tiag tiag, qhov ntim ntau lawm ntawm CA-50 castables yog qhov sib txawv ntau dua li cov cement castables tsawg. Qee cov castable manufacturers tsim txhuas silicate series castables. cov ntaub ntawv, yuav luag tsuas yog tsim cov cement castables tsawg.
