Kudzima nzira uye chinangwa
Iyo workpiece inopisa kune austenitizing tembiricha kweimwe nguva yenguva uye yobva yatonhodzwa pamwero wakakura kupfuura yakakosha kutonhora mwero kuti uwane kupisa kwekupisa kwechimiro chemartensite.
Kuvandudza kuoma kwepamusoro uye kupfeka kushorwa kweiyo workpiece
Kudzika-kupisa kudziya nzira uye chinangwa
Mushonga wekupisa wekupisa umo simbi yakadzimwa inopisa pa 250 ° C. uye yozotonhora pasi.
Kuti uchengetedze kuomarara kwepamusoro uye kupfeka kusagadzikana kweiyo yakadzima workpiece, kuderedza kusara kunetseka uye brittleness panguva yekudzima.
Nzira yekusiyanisa sei quenched uye isina kuvharwa crankshaft?
Iron inopindirana nekemikari pamwe neokisijeni mumhepo pakupisa kwakanyanya kuburitsa iron trioxide nhema. Izvi zvakasiyana nezvatinowanzoti ngura. Chatinowanzo taura nezve ngura ndechekuti iron inopindirana neokisijeni, mvura, uye zvimwe zvinhu zviri mumhepo patembiricha yekamuri kuti iumbe (chikamu chikuru che ngura) iron oxide, tsvuku.
Iron inodziiswa muokisijeni:
3Fe + 2O2 === Kupisa ==== Fe3O4
Simbi inoita ngura mumhepo:
crankshaft isina kudzimwa
quenched crankshaft
