3 hli tungsten carbide rauj
Lub rauj hniav yog qhov tseem ceeb tshaj plaws thiab yooj yim tshaj plaws ua haujlwm ntawm lub rauj zeb, yog li txhim kho cov rauj zeb, yog li kev txhim kho cov kev ua haujlwm rauj tau yog ib qho ntawm cov rauj zeb. Overlaying tungsten carbide nyob rau saum npoo ntawm rauj hniav yog ib qho ntawm cov txheej txheem tseem ceeb rau cov rauj hniav. Lub hardness ntawm nws txheej overlay ntau tshaj 60 HRC thiab muaj peev xwm rau kev ua kom muaj kev puas tsuaj. Txawm hais tias nws cov neeg tsim khoom raug nqi yog ob zaug ntau npaum li tag nrho quencing rauj, nws cov kev pabcuam lub neej tseem muaj ntau tshaj li ob zaug ntawm cov tom kawg. Yog li ntawd, lub rauj hniav kho los ntawm tus txheej txheem no muaj qhov kev ua tau zoo ntawm kev ua tau zoo.
1. Lub cev: ib lub taub hau ib lub qhov, ob chav taub hau ob chav
2. Qhov loj: Ntau qhov ntau thiab tsawg, customized
3. Khoom: zoo alloy steel, hnav-resistant steel
4. Kev nyuaj: HRC90-95 (carbides); Tungsten carbide tawv ntsej muag - HRC 58-68 (materiax); C1045 Tshav Kub Kho Lub Cev - HRC 38-45 & Kev ntxhov siab tau ntseeg; Nyob ib ncig ntawm lub qhov: HRC30-40.
Lub thickness ntawm tungsten carbide txheej yog tib yam li ntawm rab rauj hniav lub cev. Nws tsis yog tsuas yog tswj cov rauj ntawm rauj hniav txiav tab sis kuj txhim kho qhov ua tsis kam ntawm rab rauj hniav.
Ib Leeg-Txheej: Cov tuab tuab ntawm tungsten carbide txheej mus txog 5 hli; Tag nrho cov hnav-resistant thickness ncav cuag 8 hli. Nws cov kev pabcuam lub neej yog n lub sij hawm uas cov khoom zoo sib xws. Nws tuaj yeem txo tus nqi crushing thiab txuag lub sijhawm hloov.
Muab Ob Chav Txheej: Cov tuab tuab ntawm tungsten carbide txheej mus txog 8 hli; Tag nrho cov hnav-tiv taus tuab tuab mus txog 12 hli. Nws tau tsis muaj kev sib txawv.
