Cr12MoV inopisa yakakungurutswa simbi yakatenderedzwa mbariro

Cr12MoV simbi ine yakanyanya kuoma, uye avo vane muchinjiko-chikamu che300 kusvika 400 mm kana zvishoma vanogona kudzimwa zvachose.
Inogona kuchengetedza kuoma kwakanaka uye kupfeka kuramba pa300 ～ 400 ℃, kuoma kwayo kwakakwira kupfuura Cr12 simbi, uye shanduko yevhoriyamu ishoma panguva yekudzima. Inogona kushandiswa kugadzira akasiyana mold uye maturusi ane mahombe emuchinjiko, maumbirwo akaomarara, uye anomira mikuru yekukanganisa. Semuyenzaniso, kubaya kunofa nemhando dzakaomarara, kuisirwa pane yakaoma kufa, simbi yakadzika kudhirowa inofa, waya yekudhirowa inofa, yakarukwa waya ndiro, inotonhora extrusion inofa, inotonhora yekucheka zvigero, denderedzwa masaha, maturusi ekuyeresa, nezvimwe.
Cr12MoV simbi ndeyepamusoro-kabhoni, yakakwira-molybdenum lysic simbi. Iyo kabhoni yemukati yakadzikira kupfuura iyo yeCrl2 simbi, uye inowedzerwa ne molybdenum uye vanadium zvinhu, izvo zvinonyanya kunatsiridza simbi yekupisa yekupisa zvivakwa, kukanganisa kuoma uye kugovera carbide. Iyo simbi ine yakakwira kupfeka kuramba, kuoma, kuomarara, kusimba, kugadzikana kwemafuta, kusimba kwesimba, pamwe neiyo micro deformation, yakanakisa dhizaini kuita uye kuchinjika kwakawanda. Kupisa kunopfavisa tembiricha i520 ℃. Saizi yakachekwa iri pazasi 4mm uye inogona kuomeswa zvachose. Kushongedzwa kwekupfeka kwesimbi iyi 3 ~ 4 nguva yakakwirira kupfuura iyo yesimbi-yakadzika-simba simbi, uye vhoriyamu yekudzima idiki. Kuomesa kudzika: mafuta ekudzima 200 ~ 300mm.
Munguva yekristalllization process, nhamba huru ye eutectic white carbides inoumbwa (iyo carbonized substance participating inenge 20%, uye eutectic tembiricha inenge 1150 ° C). Aya carbides akaoma zvikuru uye ane brittle. Kunyangwe ma carbides akatyoka kune imwe dhigirii mushure mekukunguruka kwebillet, iyo carbides inogoverwa mumabhandi, slabs, zvidhinha, uye mirwi munzira yekutenderera, uye dhigirii rekuparadzanisa rinowedzera nehupamhi hwesimbi.

Application

Cold work inofa simbi, kuoma kwesimbi, kudzima, uye kuomesa kuoma, kupfeka kuramba, simba rakakwira kupfuura Cr12. Inoshandiswa mukugadzirwa kweakasiyana-siyana anotonhora stamping anofa uye maturusi ane mahombe-zvikamu, zvimiro zvakaoma uye zvinorema zvekushanda mamiriro, senge punching kufa, kucheka kufa, pombi inofa, kudhirowa kwakadzika kunofa, denderedzwa saw, maturusi akajairwa, uye geji Thread rolling die. , nezvimwewo.
