Ua rau hnav thiab poob ntawm cov khoom siv refractory

Cov hom tsis ua haujlwm ntawm cov khoom siv refractory hauv kev siv tuaj yeem muab sau ua peb hom qauv.

1. Vim muaj kev ntxhov siab ntawm cov khoom siv thiab cov thermal stress ntawm cov qauv, lub refractory hauv ob sab phlu ua rau cov kab nrib pleb tsis zoo (thermal zog, mechanical tev lossis ntog), uas ua rau kev puas tsuaj.

(2) Cov qauv ntawm cov khoom siv refractory hloov vim qhov infiltration ntawm slag thiab qhov kub thiab txias ntawm qhov kub thiab txias (qhov chaw ua haujlwm), yog li tsim cov txheej txheem metamorphic tshwj xeeb, thiab cov kab nrib pleb sib npaug rau cov cua sov saum npoo yog tsim los ntawm kev sib tshuam ntawm thawj thiab metamorphic txheej (Cov qauv yog tev tawm) thiab puas.

(3) Melting flow thiab abrasion vim yog cov tshuaj tiv thaiv nrog cov hlau molten, slag thiab soot feem ntau yog vim lub cim ntawm cov kua theem thiab txheej yaig (melting poob) ntawm qhov chaw ua haujlwm.
