Iyintoni ukumelana nokugqwala kwebha ejikelezileyo yentsimbi ye-alloy?

Xa kufikwa kumba wokuxhathisa ukugqwala kwebha ejikelezileyo yentsimbi ye-alloy, uhlobo oluthile lwentsimbi esetyenzisiweyo kufuneka luqwalaselwe. Iibha ezijikelezileyo zentsimbi, ezifana nebha ejikelezileyo yentsimbi ye-4140, ibha ejikelezileyo yentsimbi ye-42crmo4 kunyeIntsimbi yebha ejikelezileyo ye-aisi 4140, zaziwa ngamandla azo aphezulu kunye nokuqina kwazo. Nangona kunjalo, ukumelana kwazo nokugqwala kuya kwahluka ngokuxhomekeke kulwakhiwo oluthile lwe-alloy kunye nonyango lomphezulu.
Enye yezinto eziphambili ezinegalelo ekuchaseni ukugqwala kwe-alloy steel round bar kukubakho kwezinto ezithile ezidibanisa i-alloy. Umzekelo, i-chromium idla ngokudityaniswa kwi-alloys zentsimbi ukuze yomeleze ukuxhathisa ukugqwala. Oku kubonakala ngakumbi kwi-4140 steel round bars, eziqulethe inani elikhulu le-chromium, ezinika ukuchasana okugqwesileyo kokugqwala. Ukongeza, ubukho be-molybdenum kwiIntsimbi engqukuva eyi-42crmo4iphucula ngakumbi ukumelana kwayo nokugqwala, nto leyo eyenza ukuba ifaneleke ukusetyenziswa kwiindawo ezirhabaxa.
Ukongeza kwi-alloy composition, unyango lomphezulu weentsimbi zentsimbi ezijikelezileyo ludlala indima ebalulekileyo ekumelaneni nokugqwala. Iintsimbi zentsimbi ezijikelezileyo ezenziweyo zidlula kwinkqubo ethile yokuvelisa ukuphucula ngakumbi ukuxhathisa kwayo ukugqwala. Ngeenkqubo ezifana nonyango lobushushu kunye nokwambathiswa komphezulu, ukuxhathisa ukugqwala kwezi ntsimbi kuphucuka kakhulu, nto leyo eyenza ukuba zifaneleke kwiintlobo ngeentlobo zezicelo, kuquka iindawo zaselwandle nezemizi-mveliso.

Kubalulekile ukuqaphela ukuba nangona i-alloy steel round bar idla ngokuba nokumelana okuhle nokugqwala, isenokuba semngciphekweni weentlobo ezithile zokugqwala, ingakumbi kwiindawo ezigqwala. Ke ngoko, ukugcinwa ngokufanelekileyo kunye nokuhlolwa rhoqo kubalulekile ukuqinisekisa ukusebenza kwexesha elide kwezi ntsimbi.
Ngamafutshane, ukumelana nokugqwalaimivalo ejikelezileyo yentsimbi ye-alloyEzifana ne-4140 steel round bar, 42CrMo4 steel round bar, AISI 4140 round bar, forged steel round bar, njl. zichaphazeleka zizinto ezifana nokwakheka kwe-alloy kunye nonyango lomphezulu. Ngokuqonda ezi zinto kunye nokukhetha i-round bar efanelekileyo yesicelo esithile, iinkampani zinokuqinisekisa ukusebenza okuthembekileyo nokuhlala ixesha elide kwiindawo ezirhabaxa.
