Qhov zoo, qhov tsis zoo, thiab qhov sib txawv ntawm high-speed steel thiab cemented carbide

1. High-speed steel:

High-speed steel yog high-carbon thiab high-alloy steel. Raws li cov tshuaj muaj pes tsawg leeg, nws tuaj yeem muab faib ua tungsten series thiab molybdenum series steel, thiab raws li kev ua tau zoo, nws tuaj yeem muab faib ua cov hlau zoo tib yam high-speed steel thiab high-speed steel. High-speed steel yuav tsum muaj zog los ntawm kev kho cua sov. Nyob rau hauv lub xeev quenched, cov hlau, chromium, ib feem ntawm tungsten, thiab carbon nyob rau hauv high-ceev steel daim ntawv tsis tshua muaj zog carbides, uas yuav txhim khu lub hnav tsis kam ntawm cov hlau (hardness yuav ncav cuag HRC64-68).

Lwm qhov ntawm tungsten yog yaj nyob rau hauv lub matrix thiab ua rau kom cov liab hardness ntawm cov hlau. Lub hardness liab ntawm high-speed steel tuaj yeem ncav cuag 650 degrees. High-speed steel muaj lub zog zoo thiab toughness. Tom qab sharpening, txiav ntug yog ntse thiab qhov zoo yog ruaj khov. Nws feem ntau yog siv los tsim cov cuab yeej me me, ua haujlwm zoo li qub.

2. Cemented carbide:

Cemented carbide yog micron-order refractory high-hardness hlau carbide hmoov, uas yog tsim los ntawm firing ntawm kub thiab siab siab nrog cobalt, molybdenum, npib tsib xee, thiab lwm yam raws li ib tug binder. Cov ntsiab lus ntawm high-temperature carbides nyob rau hauv cemented carbide tshaj li ntawm high-ceev steel, nrog siab hardness (HRC75-94) thiab zoo hnav tsis kam.

Hard alloy liab hardness tuaj yeem ncav cuag 800-1000 degrees. Kev txiav ceev ntawm cemented carbide yog 4-7 zaug siab dua li cov hlau ceev. High txiav efficiency.

Cemented carbide muaj siab hardness, lub zog, hnav-tiv taus, thiab corrosion kuj, thiab yog hu ua "industrial hniav". Nws yog siv los tsim cov cuab yeej txiav, riam, cov cuab yeej cobalt, thiab cov khoom hnav-tiv taus, thiab yog dav siv hauv kev ua tub rog, aerospace thiab aviation, Mechanical processing, metallurgy, roj drilling, mining cov cuab yeej, kev sib txuas lus hluav taws xob, kev tsim kho, thiab lwm yam. Nrog rau txoj kev loj hlob ntawm downstream industries, kev lag luam thov rau cemented carbide tseem nce ntxiv. Thiab nyob rau hauv lub neej yav tom ntej, kev tsim riam phom thiab khoom siv high-tech, kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, thiab kev loj hlob sai ntawm nuclear zog yuav ua rau kom qhov kev thov rau high-tech high-zoo, thiab ruaj khov cemented carbide khoom. .
