Cr12MoV ishyushye izengurutswe ibyuma

Ibyuma bya Cr12MoV bifite ubukana bwinshi, kandi abafite igice cyambukiranya mm 300 kugeza 400 mm cyangwa munsi yacyo barashobora kuzimya burundu.
Irashobora gukomeza gukomera no kwambara kuri 300 ～ 400 ℃, ubukana bwayo burenze ibyuma bya Cr12, kandi ihinduka ryayo ni rito mugihe cyo kuzimya. Irashobora gukoreshwa mugukora ibishushanyo bitandukanye nibikoresho bifite ibice binini byambukiranya ibice, imiterere igoye, kandi ikihanganira imitwaro minini. Kurugero, gukubita bipfa bifite imiterere igoye, gushyiramo ibyuma bipfa gupfa, gushushanya ibyuma byimbitse bipfa, gushushanya insinga bipfa, icyuma cyometseho insinga, gukuramo ubukonje bipfa, imikasi yo gukonjesha imbeho, ibiti bizenguruka, ibikoresho bisanzwe, ibikoresho byo gupima, nibindi.
Ibyuma bya Cr12MoV nicyuma kinini cya karubone, icyuma kinini cya molybdenum. Ibirimo bya karubone biri hasi cyane ugereranije nibyuma bya Crl2, kandi byongewemo na molybdenum na vanadium, ibyo bikaba bitezimbere cyane ibyuma bitunganya ubushyuhe bwumuriro, gukomera no gukwirakwiza karbide. Icyuma gifite imyambarire myinshi yo kwihanganira, gukomera, gukomera, gukomera, guhagarara neza, ubushyuhe bwo gukomera, hamwe no guhindura mikorobe, imikorere myiza kandi ihindagurika cyane. Ubushyuhe bworoshya ubushyuhe ni 520 ℃. Ingano yaciwe iri munsi ya 4mm kandi irashobora gukomera rwose. Kurwanya kwambara kwicyuma bikubye inshuro 3 ~ 4 kurenza icyuma gikoresho gike gike, kandi ingano yo kuzimya ni nto. Gukomera kwimbitse: kuzimya amavuta 200 ~ 300mm.
Mugihe cyo korohereza ibintu, hashyirwaho umubare munini wa karubide yera ya eutectic (agace ka karubone kangana na 20%, naho ubushyuhe bwa eutectic bugera kuri 1150 ° C). Iyi karbide irakomeye cyane kandi yoroshye. Nubwo karbide yamenetse kurwego runaka nyuma yo kuzunguruka fagitire, karbide ikwirakwizwa mumigozi, ibisate, guhagarika, hamwe nibirundo byerekeranye no kuzunguruka, kandi urwego rwo gutandukanya rwiyongera hamwe na diameter yicyuma.
