Magnesium ramming refractory huab hwm coj yog ib qho kev faib ua feem ntau ntawm cov ntaub ntawv granular thiab ib qho kev faib ua feem tsawg heev ntawm cov binder thiab lwm pab pawg ntawm kev faib khoom, thiab txawm tias tag nrho cov nplej, hmoov muaj pes tsawg leeg, yuav tsum raug ntaus los ntawm txoj kev tsim kho kom muaj zog. Magnesia ramming loj yog tov los ntawm corundum, zoo bauxite clinker, silicon carbide raws li aggregate, txhua yam hmoov, ultra nplua hmoov, micropowder, alumina hmoov thiab admixture nrog sib tov rations raws li txawv ntau yam.
Magnesia ramming loj yog ib hom alkali amorphous refractory khoom, uas yog tsim los ntawm electromagnet los yog sintered magnesia refractory cov ntaub ntawv, superfine hmoov additive thiab tshuaj daim ntawv cog lus. Ua ntej, siab purity magnesia xuab zeb thiab magnesia hmoov yog calcined rau peb zaug kom cia tag nrho expansion thiab contraction ntawm magnesia xuab zeb thiab magnesia hmoov. Tom qab ntawd qhov kev faib ua feem ntawm cov nplej magnesia yog ua raws li kev cai tsim.
1.Spread cov khoom nyob rau hauv qab nrog thichness ntawm 100mm mus rau 150mm thiab rammedhard,
2.Ntawm qhov chaw, rov ua haujlwm ramming ib zaug ntxiv
3. Muab ib daim ntawv hlau rau ntawm qhov chaw kom tsis txhob muaj kev puas tsuaj ntawm qhov chaw thaum muab cov khoom seem thiab cov hlau kub.
