Sib piv cov khoom siv ramming thiab cov khoom pov tseg

Cov khoom siv ramming thiab cov khoom pov tseg yog ob qho khoom siv hluav taws xob, tab sis kuj muaj qhov sib txawv ntawm ob:

1. Qhov sib txawv ntawm cov khoom siv raw khoom: Cov khoom siv ramming feem ntau yog cov khoom siv ua haujlwm tsis zoo uas ua los ntawm qee qhov sib xyaw ua ke cov hmoov sib xyaw thiab hmoov ntxiv rau phau ntawv thiab cov tshuaj ntxiv, uas feem ntau yog tsim los ntawm phau ntawv lossis tshuab ramming. Ramming cov ntaub ntawv suav nrog cov ntaub ntawv corundum ramming, cov khoom siv aluminium ramming siab, cov khoom siv silicon carbide ramming, cov ntaub ntawv carbon ramming, cov ntaub ntawv silicon ramming, cov ntaub ntawv magnesia ramming, thiab lwm yam. cov ntaub ntawv, sib xyaw nrog ntau yam ntawm cov hmoov zoo tshaj plaws, fused cement los yog cov tshuaj sib xyaw ua cov ntawv ua los ntawm cov khoom siv ntau. Nws tau siv los ua kom sib txawv nruab nrab ntawm cov khoom siv cua sov ua kom sov thiab cov masonry lossis cov muab tub lim rau txheej txheej masonry.

castable yog ib hom khoom siv ua hmoov thiab hmoov ua los ntawm kev ntxiv qee yam ntawm cov ntawv nplaum rau cov khoom siv hluav taws xob. Nrog cov kua dej ntau, nws yog qhov tsim nyog rau cov khoom siv hluav taws xob tsis zoo uas tsim los ntawm casting. Peb qhov tseem ceeb ntawm cov castable yog cov khoom siv tseem ceeb, cov khoom siv ntxiv thiab kev tsis huv, uas tau muab faib ua: sib sau ua ke, hmoov thiab cov ntawv nplaum. Cov khoom siv raw suav nrog silica, diabase, andesite thiab waxstone.

2. Qhov sib txawv ntawm kev tsim kho: Cov khoom siv ramming cov neeg tsim khoom tawm tswv yim tias cov khoom siv ramming yuav tsum tau siv tusyees thiab ua haujlwm tau zoo thaum lub ramming tsim kho. Ramming cov ntaub ntawv feem ntau siv rau ib feem ntawm lub qhov cub qhov twg cov cib ua hluav taws xob tsis tuaj yeem tsim lossis qhov chaw ua masonry nyuaj. Kev tsim cov khoom siv ramming yog qhov yooj yim. Nws yog siv los ua kom cov khoom siv cua sov ua kom sov thiab cov voos voos voos lossis cov khoom ntim rau txheej txheej masonry.

Castables feem ntau yog siv los tsim ntau yam cua sov ua kom sov cov hlua thiab lwm yam kev sib xyaw ua ke. Qee hom zoo kuj tuaj yeem siv rau hauv qhov cub tawg. Piv txwv li, aluminate cement refractory castables tuaj yeem siv dav hauv ntau yam cua sov cua sov thiab lwm yam khoom siv cua sov yam tsis muaj slag, kua qaub thiab alkali xeb. Hauv cov ntu uas tau xeb los ntawm cov hlau yaj, cov hlau yaj thiab cov yaj yaj thiab muaj qhov kub ua haujlwm siab, xws li tapping troughs, tus ntaiv, lub tshuab ua kom tawg rauv taws, tapping raws, thiab lwm yam, ua ke ntawm cov calcium tsawg thiab ntshiab alumina cement tuaj yeem ua tau siv. Cov khoom siv hluav taws kub hnyiab tau ua los ntawm cov khoom lag luam zoo thiab hmoov nrog cov ntsiab lus alumina siab thiab ua kom zoo zoo.

Piv txwv li, phosphate refractory castables tuaj yeem siv dav hauv cov cua sov ua kom sov thiab ua kom sov ua kom sov cov hlau, thiab tseem tuaj yeem siv rau hauv cov coke ncu thiab cov cement ua kom sov qhov twg lawv ncaj qha nrog cov khoom siv. Hauv qee qhov chaw ntawm lub qhov cub tawg hlau thiab lwm lub nkoj uas muaj kev sib cuag ncaj qha nrog cov slag thiab cov hlau yaj, kev siv cov khoom zoo phosphate refractory castables rau kev kho dua kuj muaj qhov ua tau zoo. Hauv cov ntsiab lus, cov castable tuaj yeem siv rau qhov casting ntawm qhov tseem ceeb ntawm lub cev rauv, xws li lub qhov rooj rauv rauv thiab qhov chaw nyob ntawm qhov chaw pub mis; cov molten hlau pouring runner yog feem ntau nrum nrog castables. Tom qab lub sijhawm siv, cov castables yuav poob. Qhov chaw ua ntu zus.
