• khaws cov khoom nyob rau hauv qhuav warehouses;
• koom tes nrog cov tuam ntxhab uas muaj kev paub dhau los hauv kev xa khoom xa tawm.

Ib qho kev sib koom ua ke tso cai tsis tsuas yog txhim kho cov khoom zoo ntawm cov hlau, tab sis kuj txo qis kev siv cov khoom siv alloying, ua kom zoo dua cov nqi tsim khoom thiab xyuas kom muaj kev ruaj ntseg ntawm cov txheej txheem thev naus laus zis.

International zoo qauv rau ferrovanadium

Dab tsi yog cov qauv thoob ntiaj teb siv rau ferrovanadium?

Rau kev lag luam thoob ntiaj tebferrovanadiumNws tsis txaus los tsom tsuas yog cov ntsiab lus ntawm vanadium. Rau feem ntau metallurgical lag luam, kev ruaj ntseg ntawm cov tshuaj muaj pes tsawg leeg, impurity cov ntsiab lus, particle loj tis, kev soj ntsuam txoj kev thiab ua raws li thoob ntiaj teb los yog lub teb chaws cov qauv tseem ceeb sib npaug.

Lub xub ntiag ntawm cov txheej txheem kev cai tso cai rau peb kom paub meej kev nkag siab ntawm cov chaw tsim khoom thiab cov neeg yuav khoom, txo qhov kev pheej hmoo ntawm kev tsis pom zoo thaum lub sijhawm xa khoom thiab lav qhov ruaj khov ntawm cov khoom zoo thaum lub sijhawm kev koom tes ntev.

Nyob ntawm lub teb chaws ntawm lo lus uas peb thiab kev lag luam ntawm daim ntawv thov, ferrovanadium tej zaum yuav muab rau thoob ntiaj teb, lub teb chaws los yog koom haum technical specifications.

ISO - txoj hauv kev thoob ntiaj teb rau kev tswj hwm qhov zoo

Txawm hais tias tsis muaj cov txheej txheem ISO cais uas tswj tag nrho cov tshuaj lom neeg muaj pes tsawg leeg ntawm ferrovanadium, feem ntau cov tuam txhab xa tawm-taw qhia kom siv cov kev tswj xyuas zoo.ISO 9001 Cov.

Rau cov neeg yuav khoom qhov no txhais tau tias:

• traceability ntawm cov txheej txheem ntau lawm;
• kev tswj zoo ntawm cov khoom siv raw;
• cov ntaub ntawv xeem system;
• cov txheej txheem tswj tsis tu ncua rau txhua pawg;
• txuas ntxiv txhim kho cov txheej txheem ntau lawm.

Thaum xaiv ib tus neeg muag khoom, muaj cov ntawv pov thawj kev tswj hwm zoo qhia tau hais tias muaj qib siab ntawm cov koom haum tsim khoom, tab sis tus neeg yuav khoom tseem yuav tsum tau kuaj xyuas qhov ua tau zoo ntawm txhua pawg tiv thaiv daim ntawv pov thawj ntawm kev tshuaj ntsuam (COA), thiab tsis txhob cia siab rau qhov muaj daim ntawv pov thawj ISO.

GOST thiab cov qauv hauv tebchaws

Hauv kev lag luam ntawm Russia thiab CIS lub teb chaws, ferrovanadium tuaj yeem muab tau raws li tsoomfwv cov qauv tam sim no lossis cov chaw tsim khoom tshwj xeeb.

Cov ntaub ntawv no feem ntau tsim cov cai rau:

• yam tsawg kawg nkaus ntawm vanadium;
• siab tshaj qhov tso cai carbon cov ntsiab lus;
• silicon cov ntsiab lus;
• cov ntsiab lus ntawm aluminium;
• sulfur thiab phosphorus cov ntsiab lus;
• feem loj;
• cov cai coj mus kuaj;
• txoj kev kuaj sim.

Thaum nkag mus rau hauv daim ntawv cog lus, nws raug nquahu kom pom zoo ua ntej uas tus qauv lossis kev qhia tshwj xeeb yuav raug siv los ua lub hauv paus rau kev txais khoom.

Chaw tsim tshuaj paus Specifications

Ntau lub tuam txhab thoob ntiaj teb tsim lawv tus kheej Cov Lus Qhia Tshwj Xeeb, uas coj mus rau hauv tus account cov yam ntxwv ntawm cov khoom siv raw, khoom siv thiab tshuab smelting siv.

Xws li specifications yuav muaj xws li:

• nqaim vanadium cov ntsiab lus ntau yam;
