Qhov sib txawv ntawm Cast Steel Balls thiab Forged Steel Balls

Hauv peb lub siab nyiam, cov pob hlau tuaj yeem muab faib ua peb pawg: cam khwb cia steel pob, forged steel pob, thiab cov khoom siv cam khwb cia hlau sib tsoo. Tab sis tam sim no, nodular cam khwb cia hlau sib tsoo cov khoom siv tsis tshua muaj, thiab cov khoom siv casting thiab forging yog siv ntau dua. Txawm li cas los xij, nyob rau hauv Suav teb, 90% ntawm cov tuam txhab siv cam khwb cia sib tsoo pob raws li kev sib tsoo xov xwm, thaum lub pob forged yog siv nyob rau hauv txawv teb chaws. Cia's saib cov yam ntxwv ntawm cov pob cam khwb cia thiab cov pob forged:

Cov pob hlau uas tsim los ntawm kev nrum thiab smelting yog hu ua cam khwb cia hlau pob; cov pob hlau uas tsis tas yuav smelting thiab casting, tab sis tsuas yog tsim los ntawm forging yog hu ua forged steel pob. Txawm hais tias tsuas muaj ib lo lus sib txawv ntawm ob, qhov sib txawv loj heev.

Lub forged steel pob yog ncaj qha rhuab ntawm qhov kub thiab txias thiab tom qab ntawd forged thiab tsim los ntawm cua rauj thiab lwm yam khoom siv. Tom qab kev kho cua sov yooj yim, nws cov ntsiab lus chromium yog 0.1% txog 0.5%, thiab nws cov ntsiab lus carbon tsawg dua 1.0%. Tom qab qhov kub thiab txias forging, qhov hardness ntawm qhov saum npoo (HRC) tuaj yeem ncav cuag ≥56, tab sis vim tsis zoo hardenability ntawm cov khoom, txheej hardenable tsuas yog li 15 hli, yog li cov tub ntxhais hardness feem ntau tsuas yog ntau tshaj 30 degrees, thiab qhov loj ntawm txoj kab uas hla. ntawm lub pob steel, qhov phem tshaj qhov hardenability. Yog li ntawd, nyob rau hauv ib txwm muaj xwm txheej, forged steel npas yog kho nrog dej quenching.

Nyob rau hauv cov nqe lus ntawm hnav tsis kam, lub hardened thiab tempered siab chromium npas (HRC≥60) muaj siab hardness, uas yog ntau tshaj 2.5 npaug tshaj qhov hnav tsis kam ntawm forged steel pob. Los ntawm kev sib piv, peb tuaj yeem pom cov txiaj ntsig pom tseeb ntawm cov khoom pov tseg hla cov pob forged. Raws li kev tshawb fawb thwmsim, lub pob noj ib tuj ntawm raw ore rau forged npas yog ntau tshaj ob zaug ntawm cam khwb cia khoom.
