Chromium hlau pob|Technical Specifications & Procurement Guide
Chromium Hlau Lump yog ib qho siab -purity metallurgical raw khoom siv feem ntau hauv kev tsim cov nickel- thiab cobalt-base superalloys, siab- qib stainless hlau, thiab tshwj xeeb vuam consumables. Ua los ntawm aluminothermic txo los yog electrolytic refining, peb cov chromium lumps muaj tswj tsis tshua muaj roj cov ntsiab lus (Nitrogen, Oxygen, Carbon) los tiv thaiv inclusion defects nyob rau hauv tseem ceeb aerospace, tiv thaiv, thiab industrial turbine Cheebtsam. Muab VIM-qib hlau rau hlau alloy foundries thoob plaws North America thiab Europe txij thaum 2008.
Ntsiab nta
High Purity Matrix: Consistently maintained at >= 99.2% rau 99.8% Cr cov ntsiab lus.
Tswj Gas Impurities:Tsawg carbon, nitrogen, thiab sulfur qib tailored rau lub tshuab nqus tsev induction melting (VIM).
Optimized Loj:Uniform pob geometry (10-50mm) nrog customized sizing xaiv muaj raws li qhov kev thov kom tau raws li cov kev cai ntawm lub cub tawg.
Traceable Batch Integrity:Txhua qhov kev tsim hluav taws xob tau raug coj mus kuaj, ntsuas los ntawm ICP-OES thiab inert gas fusion, thiab muab nrog daim ntawv pov thawj Mill Test Certificate (MTC).

Daim ntawv thov
Alloying element rau npib tsib xee-base thiab cobalt-base superalloys siv nyob rau hauv aerospace turbine blades thiab av-raws li roj turbines.
Kev tsim cov corrosion-resistant, siab-kub stainless hlau thiab cov cuab yeej hlau.
Cov khoom xyaw nyoos hauv flux-cov xov hlau cored thiab coated electrodes rau nyuaj-fab thiab siab-kev ntxhov siab corrosion- cov pob qij txha tiv taus.
Grain refinement thiab hardening tus neeg saib xyuas nyob rau hauv tshwj xeeb tooj liab thiab aluminium master alloys.
Manufacturing & Quality Control
Kev tsim khoom cia siab rau lub tshuab nqus tsev refining thiab nruj feedstock xaiv kom cov kab mob kis mus rau qhov tsawg kawg nkaus.
Cov cuab yeej kuaj:Direct - nyeem optical emission spectrometers (ICP-OES) thiab automated gas determinators for oxygen, nitrogen, and hydrogen.
Kev soj ntsuam raws tu qauv:Txhua tus tib neeg cov cua sov ua tiav tag nrho spectrum tsom xam thiab inert gas fusion ua ntej crushing, sizing, thiab ntim. Cov qauv siv khaws cia los ntawm txhua qhov ntau yog khaws cia rau 24 lub hlis.

FAQ
Q: Koj puas tuaj yeem ua raws li thib peb - tog ua ntej - kev tshuaj xyuas cov khoom xa tuaj (xws li SGS, Bureau Veritas)?
A: Yog lawm, kev ywj pheej thib peb - kev tshuaj xyuas ob tog tau txais kev txhawb siab thiab tuaj yeem npaj ua ntej xa.
Q: Koj ua li cas tiv thaiv oxidation thiab ya raws thaum lub sij hawm hla dej hiav txwv?
A: Cov pob zeb tau ntim rau hauv cov thawv ntim cov hlau uas muaj cov khoom siv hauv tsev, los yog ruaj khov rau hauv cov khoom hnyav -cov ntaub ntawv polyethylene liner hauv cov hnab ntim khoom.
Q: Dab tsi yog qhov tseeb particle loj faib kam rau ua rau qib 10-50mm?
A: Tswj nruj me ntsis kom tswj tau tsawg dua 5% undersize (<10mm) and less than 5% oversize (>50mm) rau ib qho khoom xa tuaj.
