Calcined bauxiteyog ib qho ntawm feem ntau siv alumina qhov chaw hauv refractory ntau lawm. Yog tias koj tab tom yuav cov khoom siv raw rau refractory castables thiab cib, koj yuav pom sai sai tias kev thov rau "calcined bauxite price" tsis txaus kom tau txais cov lus muaj txiaj ntsig lossis kev ua tau zoo ib yam. Qhov kev sib tw tiag tiag yog specification: particle loj, Al2O3lub hom phiaj, impurity txwv, thiab yuav ua li cas tus neeg muag khoom ua pov thawj qhov sib xws los ntawm cov ntaub ntawv.
Lub zog refractory rau cov neeg yuav khoom txawv teb chaws thiab pab pawg neeg yuav khoom uas xav rov qab tsawg dua - thiab - xa email, xa ntawv sai dua, thiab kev pheej hmoo qis dua. Koj tuaj yeem siv RFQ daim ntawv txheeb xyuas qhov kawg los thov qhov kev tsocai nrog cov ntsiab lus raug cai txij hnub ib.
1) Dab tsi "Calcined Bauxite" txhais tau tias hauv Refractory Purchasing
Hauv kev siv refractory, "calcined bauxite" feem ntau yog hais txog bauxite uas tau raug cua sov-kho (calcined) los txhim kho nws cov khoom refractory thiab ruaj khov ntawm qhov kub thiab txias. Cov neeg yuav khoom siv nws ua ib qho kev sib sau los yog alumina -cov kabmob hauv:
- Refractory castables(dense castables, siab -alumina castables, qis- cement systems nyob ntawm daim ntawv qhia)
- Zoo li refractory bricksqhov twg alumina cov ntsiab lus thiab kub lub zog yog qhov tseem ceeb
- Hnav cov ntaubqhov twg abrasion kuj thiab ntom teeb meem
Txawm li cas los xij, tsis yog txhua tus calcined bauxite coj zoo ib yam. Ntau qhov chaw ore, calcination tej yam kev mob, thiab kev muab qhab nia tuaj yeem ua rau muaj qhov sib txawv loj. Yog vim li cas qhov tseeb specification yog qhov tseem ceeb.
2) 5 Cov Khoom Qhia Tshwj Xeeb tseem ceeb uas cov neeg yuav khoom yuav tsum muab
2.1 Particle loj thiab loj faib (bauxite aggregate)
Rau refractory castables thiab cib, lub sij hawm bauxite aggregate teeb meem ntau npaum li chemistry. Yog tias koj lub RFQ tsis txhais qhov loj me me, koj tuaj yeem tau txais cov khoom uas tsis haum koj tus cwj pwm sib xyaw, ntim ntim, lossis ua tiav cov khoom tiav.
Yam tsawg kawg, muab:
- Lub hom phiaj loj npaum li cas (piv txwv li: 0-1mm, 1-3mm, 3-5mm, los yog koj cov seem sab hauv)
- Txawm hais tias koj xav tau ib feem lossis ntau feem rau kev sib xyaw
- Koj qhov kev kam rau siab rau oversize / undersize (yog tias tsim nyog)
2.2 Ib2O3Lub hom phiaj (Al2O3 bauxite)
Ntau tus neeg yuav khoom tshawb nrhiav Al2O3 bauxite vim tias qib alumina feem ntau siv los faib cov bauxite zoo. Muab cov Al2O3lub hom phiaj uas haum rau koj cov khoom thiab tus nqi - lub hom phiaj kev ua tau zoo. Yog tias koj tus qauv sab hauv tso cai rau ntau yam, xa qhov tsawg kawg nkaus thiab lub hom phiaj uas koj xav kom tus neeg muag khoom ntsib.
2.3 impurity txwv raws li koj daim ntawv thov
Cov impurities tuaj yeem cuam tshuam kev ua tau zoo nyob ntawm koj qhov chaw sov thiab daim ntawv qhia. Tsis yog siv cov lus qhia dav dav, txhais qhov tseem ceeb rau koj cov txheej txheem. Yog tias koj twb muaj qhov kev lees paub spec, qhia qhov pib. Yog tias koj tsis ua, qhia rau tus neeg muag khoom koj daim ntawv thov thiab kev ua haujlwm kom lawv thiaj li pom zoo rau qib ua tau zoo.
2.4 Cov ntaub ntawv siv: castables vs bricks, thiab cov kev pabcuam
"Calcined bauxite rau refractory" tuaj yeem ua haujlwm sib txawv. Cov bauxite tib yam yuav coj txawv txawv nyob ntawm seb koj puas tsim cov castables lossis cib, thiab seb koj cov ntaub ntawv puas raug puas, corrosion, lossis thermal cycling. suav nrog:
- Yam khoom: castable los yog cib
- Cov kev pabcuam kub thiab thermal voj voog profile
- Lub luag haujlwm tseem ceeb ntawm kev coj ua (kev puas tsuaj, corrosion, spalling, thiab lwm yam)
2.5 Packing thiab logistics yuav tsum tau
Rau kev yuav khoom txawv teb chaws, ntim khoom cuam tshuam rau ob qho tib si kev tiv thaiv cov khoom siv thiab kev ua haujlwm ntawm kev thauj khoom. Qhia:
- Hnab hom (piv txwv li, 25kg hnab) lossis jumbo hnab yuav tsum tau
- Palletization thiab kev tiv thaiv noo noo nyiam nyiam
- Qhov chaw nres nkoj qhov chaw thiab xa khoom ncua sij hawm cia siab
3) COA Daim Ntawv Teev Npe: Yuav Nug Dab Tsi Los Ntawm Koj Tus Neeg Muag Khoom
Daim ntawv teev npe COA muaj zog txo qis kev pheej hmoo zoo thiab pab koj sib piv cov neeg xa khoom ncaj ncees. Rau calcined bauxite, thov COA uas suav nrog:
- Chemistry: Al2O3thiab lwm yam tseem ceeb chemistry yam xav tau los ntawm koj tus qauv sab hauv
- Particle loj pom zoo: teev ntau yam thiab kev tshuaj ntsuam xyuas
- Batch traceability: batch naj npawb, hnub tsim khoom, thiab packing list alignment
- Sampling sib xws: nug seb cov qauv coj li cas (ib pawg, ib qho, lossis ib qho khoom xa tuaj)
Ib yam li qhov tseem ceeb: paub meej tias tus neeg xa khoom tuaj yeem muab COA formatting zoo sib xws thoob plaws kev xa khoom. Cov neeg muag khoom zoo tshaj plaws khaws cov ntaub ntawv ruaj khov uas yuav khoom thiab QC pab pawg tuaj yeem taug qab lub sijhawm.
4) Cov neeg yuav khoom yuam kev (thiab yuav ua li cas zam lawv)
- yuam kev 1: Tsuas yog thov rau "siab Al2O3". Yog tsis muaj qhov loj me me, cov khoom siv yuav tsis haum koj daim ntawv qhia txawm tias chemistry zoo.
- Qhov yuam kev 2: Tsis qhia meej seb koj puas xav tau tag nrho lossis nplua. Ntau qhov project xav tau ntau qhov feem; "ib qho loj nkaus xwb" RFQs feem ntau ua rau cov khoom tsis sib xws.
- Qhov yuam kev 3: Tsis quav ntsej cov ntaub ntawv. Yog tsis muaj COA thiab traceability, koj tsis tuaj yeem kuaj xyuas qhov ua tau zoo ntawm kev xa khoom.
- yuam kev 4: Tsis txuas spec rau daim ntawv thov. Ib tus neeg muag khoom tuaj yeem pom zoo kom qib zoo dua thaum lawv paub koj thaj tsam hauv ob sab phlu thiab hnav mechanism.
5) Cov Lus Ceeb Toom Kawg rau Kev Yuav Khoom sai dua, nyab xeeb dua
Rau cov neeg yuav khoom thoob ntiaj teb, qhov zoo tshaj plaws calcined bauxite mov tsis yog hais txog nqe xwb. Nws yog hais txog kev rov ua dua: qhov loj me me, cov ntaub ntawv meej meej, thiab kev sib raug zoo ntawm tus neeg muag khoom COA thiab koj tus qauv lees paub. Thaum koj RFQ suav nrog particle loj faib, Al2O3Lub hom phiaj, daim ntawv thov cov ntsiab lus, thiab daim ntawv teev npe COA, cov neeg muag khoom tuaj yeem teb sai dua thiab muaj kev xav tsawg dua -txo ob qho tib si kev pheej hmoo thiab lub sijhawm yuav khoom.
Yog tias koj xav tau cov lus qhia ceev ceev, xa cov qauv RFQ saum toj no nrog koj lub hom phiaj loj feem thiab qhov chaw nres nkoj. Tus neeg xa khoom tuaj yeem lees paub qib, ntim khoom, sijhawm ua haujlwm, thiab cov ntaub ntawv xaiv hauv ib qho lus teb.
