Chromium Carbide Hmoov High Purity Supplier
Product Description
Chromium carbide hlau chromium (chromium trioxide) thiab carbon yog carbonized hauv lub tshuab nqus tsev.Nws cov mis molecular yog Cr3C2 (theoretical hnyav feem pua ntawm cov pa roj carbon yog 13%), qhov ceev yog 6.2g / cm3 thiab hardness yog siab dua HV2200.Cov tsos ntawm chromium carbide hmoov yog silver grey.Chromium carbide hmoov yog lub siab melting point inorganic khoom nrog zoo hnav tsis kam, corrosion kuj thiab oxidation kuj nyob rau hauv kub kub (1000-1100 degrees).

Daim ntawv thov tseem ceeb
Lub lattice ntawm chromium carbide yog qhov zoo thiab qhov tsis zoo, nrog lub melting point ntawm 1895 ° C. Vim nws cov yam ntxwv zoo heev ntawm hnav tsis kam, corrosion kuj thiab kub tsis kam, nws yog tsuas yog siv nyob rau hauv:
● Tsim cov khoom siv vuam tshwj xeeb, surfacing series electrodes, flux-cored xov hlau.
●Cemented carbide, ntxiv Cr3C2 hauv kev tsim cov cemented carbide tuaj yeem tsis tsuas yog kho cov WC nplej, tab sis kuj txhim kho lub zog thiab hardness ntawm cov hlau, thiab tuaj yeem txhim kho corrosion kuj ntawm cov alloy.
●Thermal spraying hmoov cov ntaub ntawv, raws li Cr3C2 thiab ntxiv Nicr superalloy rau cov txheej txheem alloy hmoov, siv plasma spraying, tuaj yeem ua rau hnav-resistant, corrosion-resistant, high-temperature resistant coatings, dav siv nyob rau hauv kiv cua, seals yog tawg, Boiler "plaub raj", thiab lwm yam.
●Arc txau xaim thiab submerged arc welded tubular xaim, arc txau xaim ntxiv nrog Cr3C2 cov khoom, uas txhim kho qhov kub thiab txias tsis kam.Nws yog siv rau hauv kev kho thiab kev tiv thaiv kev saib xyuas ntawm "plaub kav" ntawm boiler, thiab hnav-tiv taus ntawm cov hlau ua cov ntaub zawj hauv kev lag luam metallurgical.Hauv ob sab phlu, fais fab nroj tsuag thee sib tsoo nyiaj, vim yog siv Cr3C2 ntxiv tubular vuam hlau surfacing tiv thaiv, zoo heev txhim kho lub neej kev pab cuam.
