Proses bilong hat tritmen ol i save yusim planti taim long hai kromium kast ain em long hatim i go long 950~1000 digri , na bihain bihain long 200~260 digri bilong liklik tempereja tempering.
Hae tempereja mas peleting tritmen 1140~1180 digri insulesen blong 16h ea kolkol, i save mekem i kam gud moa impak strong mo wear resistens{{3} Hae tempereja sferik tritmen i save mekem olgeta kabaed globular, i save karemaot o daonem seperesen blong bigfala mas mo kontinu netwok kabaed long matriks, speseli wan spesel kabaed blong wan spesel namba blong wan namba blong wan namba blong wan yunifom matriks long matriks, sperik karbaed blong wan spesel namba blong wan spesel namba blong wan spesel namba blong wan spesel namba blong wan namba blong . austenite. Sapos taim bilong insulation i go daun stret, ol hap hap hap inap kamap gutpela —{5}} Defisiensi bilong dispela proses em olsem proses i yusim moa hat eneji.
Hitim i go long 1050 digri , na bihain mekim 550 digri tempering, olsem wanem dispela bai kamap?
Bilong bosim spit bilong hatim skin, i gutpela sapos yu stap hat inap wanpela taim long 650 aua bilong . Mi bin mekim bipo, long paia i kukim 61- - - -65 HRC.
Bikpela proses em: kasting bihain long softening na annealing, isi long prosesim, prosesim bihain long ea kol i kleim na liklik tempereja long stresim tempering{{0} Yusim bilong hatnes i save nidim long HRC 58-62, we planti bilong ol i yusim long ol slari pam hap na ol narapela wear na ol narapela hap bilong en na werim ol hap{2}}}
We are a high chromium production base, generally providing Cr 24, Cr 26, Cr 28, Cr15Mo3, etc., including the softening annealing in the middle and quenching and tempering. We now use quenching liquid quenching, quenching process parameters are: 650 degrees insulation for 2 hours, heating to 960 degrees insulation bilong 3.5 aua i wok long lus; temperaja we i mekem man i harem nogud 380~400,4~6 aoa insulasen. Grindim bal spesifikasen φ 40- φ φ 80.
Proses em 1050 i daunim + 250~350 i mekim yu bel hevi
