Magnesia-chrome ramming loj yog ib qho alkaline monolithic (tsis zoo li) refractory. Nws yog batched los ntawm sintered magnesia, fused magnesia thiab chromite / pre-reacted magnesia-chrome spinel raws li aggregate thiab nplua, ua ke nrog ib tug composite binder thiab sintering pab.

 

Qhov sib tov yog muab qhuav los yog ze-qhuav. Tsis muaj dab tsi ntxiv rau ntawm qhov chaw ua haujlwm: cov khoom yog compacted ncaj qha nrog cov cuab yeej tes los yog pneumatic rammers kom txog thaum txheej tuab, ces rhuab thiab sintered hauv kev pabcuam.

 

Tom qab thawj lub tshav kub-up txheej compacted tsim ib tug periclase - magnesia-chrome spinel qauv. Cov qauv ntawd yog tag nrho cov ntsiab lus ntawm cov khoom: nws yog dab tsi nqa kev sib cuag nrog cov yooj yim slag ua ke nrog txhua yam hnav.

 

Qib chemistry, kev ntsuas qhov loj me thiab daim ntawv qhia yog hloov kho rau lub qhov cub, thaj tsam hauv ob sab phlu thiab lub hom phiaj phiaj xwm lub neej tom qab kev tshuaj xyuas nrog peb cov engineers.

 

 

1. ntom tom qab ramming - ntiav slag nkag

Ramming compacts txheej rau qis porosity dua li tib chemistry mus txog thaum nws raug nrum. Lub periclase - spinel matrix kuj tsis zoo wetted los ntawm yooj yim slag. Tawm tsam magnesia-chrome castable ntawm kev sib piv chemistry, rammed txheej cia slag nkag mus tob, yog li lub ntsej muag ua haujlwm erodes es tsis txhob raug puas tsuaj los ntawm qab.

 

2. Volume stability nyob rau hauv load

Refractoriness-under-load pib ntawm 1450℃(0.2 MPa) thoob plaws qib. Nyob rau hauv lub sij hawm ntev load lub hauv ob sab phlu tsis o los yog nkag mus rau hauv lub chaw ua hauj lwm, yog li lub cub tawg geometry thiab clearance yog khaws cia.

 

3. Tiv thaiv kev ntxuav thiab cuam tshuam

Lub compacted, interlocked grain qauv resists abrasive txiav txim ntawm txav molten hlau, slag thiab nqi - hom hnav uas tshem tawm cov hlua hauv launders thiab converter bottoms.

 

4. Tolerates thermal cycling

Pib-nres kev ua haujlwm, tapping thiab them rov qab nthuav dav thiab cog lus rau hauv ob sab phlu. Cov qauv rammed absorbs qhov kev txav no es tsis txhob tsim cov kab nrib pleb los ntawm kev sib tsoo ntawm lub cib hauv ib cheeb tsam.

 

5. Yuav luag tsis muaj dej dawb - muaj kev nyab xeeb dua qhuav-tawm

Vim tias qhov sib xyaw yog muab qhuav los yog ze-qhuav, muaj me ntsis dej dawb los nyem thaum tshav kub kub. Cov ntu tuab tuaj yeem qhuav yam tsis muaj qhov ua rau muaj kev pheej hmoo tias lub castable ntawm tib lub thickness nqa, thiab lub sij hawm qhuav tawm yog luv dua.

 

 

Non-ferrous metallurgy - thawj daim ntawv thov

Copper, npib tsib xee thiab txhuas smelting: flash smelting furnace settler thiab slag kab, converter hauv qab thiab phab ntsa, slag fuming rauv, ncej rauv hearth hauv ob sab phlu, slag notch thiab matte / slag launders.

 

Hlau thiab hlau

AOD thiab VOD converter bottoms, ladle slag kab, hluav taws xob arc rauv hearth hauv qab thiab hnyav eroded ntug dej, tapping spouts thiab runners.

 

Rauv hauv qab - AOD / VOD, tooj liab converters, submerged-arc rauv

Lub hauv qab pom zoo li qub yaj thiab slag rau tag nrho cov phiaj xwm ntxiv rau hlau txav ntawm txhua tus kais. A dense, low-porosity rammed layer resists slag penetration and creep, which keeps melt away from the shell (the breakout scenario) and stretches bottom campaign life.

 

Slag kab - ladles thiab non-ferrous smelting furnaces

Lub slag kab yog tib cheeb tsam nyob rau hauv tas li slag nres. Qhov qis-porosity, spinel-bearing qauv slows tus nqi corrosion, uas yog qhov txiav txim siab seb tus so ntawm lub hauv ob sab phlu outlives cov slag kab los yog tsis.

 

Slag notches thiab yaj launders

Ntawm no hom tsis ua hauj lwm yog ntxuav tawm thiab cuam tshuam, tsis yog tshuaj tua kab mob. Lub rammed monolithic hauv ob sab phlu tsis muaj cov pob qij txha los qhib, thiab kev puas tsuaj hauv cheeb tsam tuaj yeem raug txiav rov qab thiab rov rammed hauv cov khaubncaws sab nraud povtseg yam tsis muaj kev rov tsim dua tshiab - kho tsis tau.

Yuav ua li cas nyeem cov ntawv qib

 

Tsis pub dhau qhov no, nce Cr₂O₃ nce qhov ceev thiab refractoriness-hauv-load, thiab txhim kho kev tiv thaiv rau cov slag yooj yim - ntawm tus nqi raw khoom ntau dua. Hauv kev xyaum: MC-55 / MC-60 mus rau slag-kab thiab da dej zones qhov twg corrosion txiav txim siab qhov kev sib tw; MC-65 mus rau hauv qab thiab thaub qab thaj chaw uas lub load yog txhua yam thiab tus nqi ib tonne tseem ceeb dua.

 

Cov txiaj ntsig saum toj no yog cov txiaj ntsig zoo rau qhov raug rho tawm haujlwm thiab qhuav hauv ob sab phlu, tsis lav qhov tsawg kawg nkaus. Kev lees paub qhov tseem ceeb, qauv qauv thiab cov qauv kev xeem raug kho nyob rau hauv daim ntawv cog lus technical rau txhua qhov kev txiav txim.

 

 

Muab daim ntawv

Muab qhuav, npaj rau ram. Qhov siab tshaj plaws ntawm cov nplej loj thiab kev ntsuas qhov nkhaus yog teem rau ib cheeb tsam thiab ib ntu tuab thiab paub tseeb tias nyob rau theem kev txiav txim.

 

Ntim

Standard xaiv: 25kg woven hnab, ces loaded rau hauv 1000kg FIBC (jumbo hnab) rau hiav txwv freight. Lwm txoj kev ntim khoom tuaj yeem sib tham.

 

Qauv thiab MOQ

Qauv kom muaj nuj nqis thiab qhov tsawg kawg nkaus txiav txim kom muaj nuj nqis raug lees paub los ntawm rooj plaub nrog peb pab neeg muag khoom, nyob ntawm qib thiab qhov chaw.

 

Cov qib kev cai
