Qhov sib txawv ntawm Cast Steel grit thiab bearing steel grit

1) Cov khoom siv raw sib txawv.

Lubcov hlau cam khwb ciayog ua los ntawm cov hlau seem + hlau smelting;Cov hlau nplaum uas muaj zogyog cov hlau bearing, nrog rau qhov siab thiab sib xws hardness thiab hnav tsis kam.

2) Cov txheej txheem ntau lawm txawv.

Cov hlau cam khwb cia grit yog ua los ntawm smelting thiab casting, thiab muaj qhov tsis zoo; Bearing steel grit yog bearing steel ncaj qha quenching thiab kho cua sov, tsis muaj qhov tsis zoo.

3) Cov khoom siv hlau sib txawv.

Cov hlau tseem ceeb uas muaj nyob rau hauv cov hlau grit yog: C, Mn, Si, S, P; Cov hlau grit muaj cov hlau muaj nqis - Cr, nws tuaj yeem txhim kho lub neej qaug zog thiab hnav tsis kam.

4) Qhov tsos txawv.

Qhov saum npoo ntawm cov hlau cam khwb cia yog tawg los ntawm cov hlau cam khwb cia thiab muaj cov duab arc;

Cov hlau bearing grit yog tawg ncaj qha los ntawm cov hlau bearing tom qab quenching mus rau hauv grit, nws yog qhov ntse heev.

5) Kev siv sib txawv

Cov hlau cam khwb cia feem ntau yog siv raukev xuab zeb, kev tua xuab zeb, Kev ntxuav xuab zeb hlau, Kev npaj nto,Kev txhaj tshuaj peening, Xuab zeb tua

Cov hlau nplaum uas muaj cov kabmob tuaj yeem siv rau kev xuab zeb, tshem tawm xeb, tua peening, tua blasting,

Vim tias nws muaj zog heev, nws tuaj yeem siv tshwj xeeb rau kev txiav granite thiab pob zeb,

6) Tus nqi txawv.

Cov hlau cam khwb cia grit pheej yig dua, cov hlau bearing grit kim dua, tus nqi ntawm cov khoom siv raw tsis zoo ib yam. Cov hlau bearing grit muaj cov hlau muaj nqis - chromium, los ntawm cov txheej txheem tsim khoom tshwj xeeb, cov qauv metallographic zoo heev, cov khoom tiav tag nrho, qhov nyuaj sib xws, lub sijhawm voj voog siab, tuaj yeem txhim kho qhov rov qab tau zoo (kev sib txhuam hauv cov txheej txheem ntawm kev xuab zeb blasting maj mam txo qis), yog li txo qhov kev siv abrasive txog li 30%.
