Dab tsi yog cov nyhuv ntawm steel fiber ntxiv rau refractory castables:
1. Txhim kho qhov toughness ntawm refractory castables.
2. Txhim kho qhov hnav tsis kam ntawm refractory castables.
3. Txhim kho cov neeg kho tshuab kev cuam tshuam tsis kam ntawm refractory castables.
4. Txhim kho thermal shock stability ntawm refractory castables, uas kuj yog lub luag haujlwm tseem ceeb.
Qhov ntsuas kub tseem ceeb rau kev ntxiv steel fibers rau refractory castables yog 1350 degree. Yog tias cov castable siv rau cov cheeb tsam uas muaj kev pabcuam kub tshaj 1350 degree, nws yuav tsis tuaj yeem ua nws lub luag haujlwm, yog li xav tau cov hlau fiber ntau ntxiv. Zoo li qee qhov castables siv rau qhov chaw siab tshaj 1400 degree, tsis tas yuav ntxiv cov hlau fibers. Tsis tsuas yog nws tsis muaj txiaj ntsig zoo, tab sis nws nce tus nqi ntawm cov castable. Refractory castable nrog steel fiber reinforced yuav siv tau rau qhov chaw xws li pem hauv ntej thiab nram qab kiln lub qhov ncauj ntawm cement rotary kiln, txiv qaub rotary kiln, thiab pellet teb kiln thiab lwm yam.. yuav siv tau rau masonry. Steel fiber reinforced refractory castable yog tsim nyog. Cov khoom siv tsis yog tsuas yog tensile thiab compressive, tab sis kuj qaug zog-resistant thiab hnav-resistant.
Hlau fiber ntau tsis yog tsuas yog haum rau refractory castables, tab sis kuj haum rau refractory plastics thiab kub ramming cov ntaub ntawv. Ntxiv qhov tsim nyog ntawm cov hlau fiber ntau rau cov yas thiab cov khoom siv ramming tuaj yeem txhim kho qhov kev tiv thaiv kom tawg thiab tev. Ntxiv mus, thaum lub sij hawm tu txheej txheem, ntxiv steel fibers yuav txo tau cov linear shrinkage ntawm castables, yas thiab lwm yam unshaped refractory ntaub ntawv. Kev sib ntxiv ntawm cov hlau fiber ntau yuav tsum tsim nyog, kev hloov pauv sab hauv ntawm cov khoom siv refractory castable yuav tshwm sim yog tias cov hlau fiber ntau ntxiv. Thaum lub refractory castable yog sintered ntawm qhov kub thiab txias, yog hais tias muaj fiber ntau ntxiv, cov expansion coefficient yuav nce thiab thermal conductivity kuj yuav nce. Tshwj xeeb tshaj yog thaum kev tsim kho, ntau cov hlau fiber ntau yuav ua rau muaj teeb meem tsis tsim nyog rau kev tsim kho.
Muaj ntau hom refractory castables nrog steel fibers, xws li siab alumina steel fiber ntau castables, corundum steel fiber castables, mullite steel fiber refractory castables, thiab silicon carbide steel fiber ntau refractory castables. Cov no yog Composite Hom ntawm refractory castable. Qhov feem ntawm steel fiber ntau ntxiv tuaj yeem hloov kho raws li kev siv.
