Cr12MoV intsimbi eshushu eqengqelekayo imivalo engqukuva

Intsimbi ye-Cr12MoV inokuqina okuphezulu, kwaye abo banecandelo elinqamlezayo le-300 ukuya kwi-400 mm okanye ngaphantsi banokucinywa ngokupheleleyo.
Iyakwazi ukugcina ubunzima obuhle kunye nokumelana nokunxiba kwi-300 ～ 400℃, ukuqina kwayo kuphezulu kunentsimbi ye-Cr12, kwaye ukuguqulwa kwevolumu kuncinci ngexesha lokucima. Ingasetyenziselwa ukwenza iimold ezahlukeneyo kunye nezixhobo ezinamacandelo amakhulu anqamlezayo, iimilo ezintsonkothileyo, kunye nokumelana nomthwalo omkhulu wempembelelo. Umzekelo, ukubetha kufa ngeemilo ezintsonkothileyo, ukufakwa kwi-complex dies, umzobo onzulu wentsimbi uyafa, umzobo wocingo uyafa, ipleyiti yocingo enentambo, i-extrusion ebandayo iyafa, izikere zokusika ezibandayo, isarha setyhula, izixhobo eziqhelekileyo, izixhobo zokulinganisa, njl.
Intsimbi ye-Cr12MoV yintsimbi ephezulu yekhabhoni, i-molybdenum lysic. Umxholo wayo wekhabhoni ungaphantsi kakhulu kuneyentsimbi ye-Crl2, kwaye yongezwa kunye ne-molybdenum kunye ne-vanadium element, ephucula kakhulu iipropathi zensimbi zokucutshungulwa kwe-thermal, ukuqina kwempembelelo kunye nokusabalalisa i-carbide. Intsimbi inokumelana nokunxiba okuphezulu, ukuqina, ukuqina, ukuqina, ukuzinza kwe-thermal, amandla acinezelayo, kunye ne-micro deformation, ukusebenza kakuhle okubanzi kunye nokuguquguquka okukhulu. Ubushushu obuthambisayo bungama-520℃. Ubungakanani bokusika bungaphantsi kwe-4mm kwaye bunokuqina ngokupheleleyo. Ukuxhatshazwa kokugqoka le ntsimbi yi-3 ~ 4 amaxesha aphakamileyo ngaphezu kweso sisixhobo esincinci, kwaye umthamo wokucima uncinci. Ukuqina kobunzulu: ukucima ioli 200 ~ 300mm.
Ngethuba lenkqubo ye-crystallization, inani elikhulu le-eutectic white carbides lenziwe (i-carbonized substance fraction imalunga ne-20%, kwaye ukushisa kwe-eutectic malunga ne-1150 ° C). Ezi carbides zinzima kakhulu kwaye zine-brittle. Nangona i-carbides iphukile kwiqondo elithile emva kokuqengqeleka kwe-billet, i-carbides ihanjiswa kwiibhendi, ii-slabs, iibhloko, kunye neemfumba ecaleni kwendlela yokujikeleza, kwaye iqondo lokuhlukana liyanda kunye nobubanzi bensimbi.
