Ramming khoom manufacturers piav qhia lub luag haujlwm ntawm refractory ramming cov ntaub ntawv hauv kev nthuav dav

Cov khoom tseem ceeb: phab ntsa hauv nruab nrab ntawm lub qhov cub hluav taws xob, lub qhov cub tshwj xeeb phab ntsa rau coreless induction rauv (intermediate zaus furnace), insulating mortar, npog tus neeg sawv cev, slag tshem tawm, castable, ramming khoom thiab lwm yam khoom. Cia peb tsom mus rau cov khoom siv hluav taws kub-resistant ramming:

Cov khoom siv refractory ramming yog tsim los ntawm kev faib ua feem ntau ntawm cov ntaub ntawv granular thiab feem tsawg ntawm cov binders thiab lwm yam khoom. Nws tseem yog tsim los ntawm granules thiab hmoov cov ntaub ntawv. Nws yuav tsum tau tsim los ntawm kev muaj zog ramming. khoom.

Vim tias cov khoom siv ramming feem ntau yog siv rau kev sib cuag ncaj qha nrog cov yaj, nws yuav tsum tau hais tias cov ntaub ntawv granular thiab hmoov yuav tsum muaj qhov ntim siab, compactness thiab corrosion kuj. Rau induction furnaces, lawv yuav tsum muaj rwb thaiv tsev.

Cov khoom sib txuas ntawm cov khoom sib tsoo yuav tsum raug xaiv kom tsim nyog, qee qhov tsis siv tus neeg sawv cev sib txuas, thiab qee qhov tsuas yog ntxiv me me ntawm flux. Cov ntaub ntawv acidic ramming feem ntau yog siv los ua cov ntaub ntawv xws li sodium silicate, ethyl silicate, thiab silica gel. Ntawm lawv, cov ntaub ntawv qhuav ramming feem ntau yog borate; alkaline ramming cov ntaub ntawv feem ntau yog siv magnesium chloride thiab sulfate; Cov pa roj carbon ntau tuaj yeem tsim cov pa roj carbon-bonded organics thiab cov ntaub ntawv ib ntus ntawm qhov kub thiab txias. Ntawm lawv, cov khoom siv qhuav ramming yog ntxiv nrog rau qhov tsim nyog ntawm cov hlau muaj flux. Chromium ramming cov ntaub ntawv feem ntau yog siv los ua manspins.

Piv nrog rau lwm cov ntaub ntawv tsis zoo li refractory ntawm tib cov khoom, cov khoom siv ramming yog qhuav los yog ib nrab qhuav thiab xoob. Lub compact qauv yog tau los ntawm muaj zog ramming. Tsuas yog thaum rhuab mus rau sintering kub, lub cev ua ke yuav muaj zog. Tom qab cov khoom siv ramming tau tsim, cov txheej txheem cua sov sib txawv tuaj yeem siv los txhawb kev sib zog los yog sintering raws li cov yam ntxwv ntawm cov khoom sib tov.
