Qhov sib txawv ntawm Tungsten Carbide thiab HSS Cov cuab yeej txiav

Ntxiv nrog rau cov ntaub ntawv tungsten carbide, cov cuab yeej txiav tuaj yeem tsim nrog cov ntaub ntawv siab ceev. Txawm li cas los xij, vim muaj cov tshuaj sib txawv thiab cov txheej txheem tsim khoom ntawm tungsten carbide thiab high-speed steel, qhov zoo ntawm cov cuab yeej npaj txiav kuj txawv.

1. Cov khoom siv tshuaj

High-speed steel, tseem hu ua high-speed tool steel lossis pem hauv ntej steel, feem ntau hu ua HSS, cov khoom siv tshuaj tseem ceeb yog carbon, silicon, manganese, phosphorus, sulfur, chromium, molybdenum, nickel, thiab tungsten. Qhov kom zoo dua ntawm kev ntxiv tungsten thiab chromium rau pem hauv ntej steel yog los txhim kho cov softening kuj ntawm cov khoom thaum rhuab, yog li ua rau nws txiav ceev.

Tungsten carbide, tseem hu ua cemented carbide, yog cov khoom siv alloy raws li cov hlau refractory complex compounds thiab hlau raws li ib tug binder. Cov sib xyaw ua ke nyuaj yog tungsten carbide, cobalt carbide, niobium carbide, titanium carbide, tantalum carbide, thiab lwm yam, thiab cov binders feem ntau yog cobalt, npib tsib xee, hlau, titanium, thiab lwm yam.

2. Lub cev muaj zog

Lub zog flexural ntawm lub hom phiaj siab ceev hlau yog 3.0-3.4 GPa, qhov cuam tshuam toughness yog 0.18-0.32 MJ / m2, thiab hardness yog 62-65 HRC (thaum qhov kub nce mus rau 600 ° C uas hardness yuav yog. 48.5 HRC). Nws tuaj yeem pom tias cov hlau kub ceev muaj cov yam ntxwv ntawm lub zog zoo, hnav tsis kam, nruab nrab kub tsis kam, thiab tsis zoo thermoplasticity. Ntawm chav kawm, cov kev qhia tshwj xeeb ntawm kev kub ceev steel yog ze ze rau nws cov tshuaj muaj pes tsawg leeg thiab cov khoom siv raw.

Lub zog compressive ntawm feem ntau siv tungsten carbide yog 6000 MPa thiab hardness yog 69 ~ 81 HRC. Thaum qhov kub nce mus txog 900 ~ 1000 ℃, qhov hardness tseem tuaj yeem khaws cia li ntawm 60 HRC. Tsis tas li ntawd, nws muaj lub zog zoo, toughness, hnav tsis kam, kub tsis kam, thiab corrosion kuj. Txawm li cas los xij, qhov tshwj xeeb kev ua tau zoo ntawm cemented carbide yog ze ze rau nws cov tshuaj muaj pes tsawg leeg thiab cov khoom siv raw.

3. Cov txheej txheem ntau lawm

Cov txheej txheem ntawm kev kub ceev steel feem ntau yog: zaus rauv smelting, tawm ntawm qhov cub refining, nqus degassing, electro slag remelting, ceev forging tshuab, forging rauj, precision tshuab blanking, kub dov rau hauv cov khoom, phaj caij, thiab kos duab. rau hauv cov khoom.

Cov txheej txheem ntau lawm ntawm tungsten carbide feem ntau yog: sib tov, ntub milling, ziab, nias, thiab sintering.

4. Kev siv

High-speed steel feem ntau yog siv los tsim cov cuab yeej txiav (xws li kev xyaum, kais, thiab cov hniav) thiab cov cuab yeej precision (xws li hobs, iav shapers, thiab broaches).

Tsuas yog cov cuab yeej txiav uas tungsten carbide kuj yog siv los ua cov mining, ntsuas, molding, hnav-resistant, kub-kub, thiab lwm yam cuab yeej zoo li.

Feem ntau nyob rau hauv tib lub sijhawm, kev txiav ceev ntawm cov cuab yeej tungsten carbide yog 4 mus rau 7 npaug siab dua li cov hlau kub ceev, thiab lub neej yog 5 mus rau 80 npaug siab dua.

Yog tias koj txaus siab rau cov khoom lag luam tungsten carbide thiab xav paub ntau ntxiv thiab cov ntsiab lus, koj tuaj yeem tiv tauj peb hauv xov tooj lossis xa ntawv ntawm sab laug, lossis xa US MAIL hauv qab ntawm nplooj ntawv.
