Kuyini ukumelana nokugqwala kwe-alloy steel round bar?

Uma kukhulunywa ngokumelana nokugqwala kwe-alloy steel bar round, uhlobo oluthile lwensimbi esetshenzisiwe kufanele lucatshangelwe. Imigoqo eyindilinga yensimbi, efana nebha eyindilinga yensimbi engu-4140, ibha eyindilinga yensimbi engama-42crmo4 kanyeaisi 4140 ibha yensimbi eyindilinga, zaziwa ngamandla azo aphakeme nokuqina kwazo. Kodwa-ke, ukumelana nokugqwala kwazo kuzohluka ngokuya ngokwakheka kwe-alloy ethile nokuphathwa kwendawo.
Esinye sezici ezibalulekile ezinomthelela ekuphikiseni ukugqwala kwe-alloy steel bar round bar ubukhona bezakhi ezithile ze-alloying. Isibonelo, i-chromium ivame ukungezwa kuma-alloys ensimbi ukuze kuthuthukiswe ukumelana nokugqwala. Lokhu kubonakala ikakhulukazi kumabha ayindilinga ensimbi angu-4140, aqukethe inani elikhulu le-chromium, okuwanika ukumelana nokugqwala okuhle kakhulu. Ngaphezu kwalokho, kukhona i-molybdenum42crmo4 insimbi eyindilingaithuthukisa futhi ukumelana nokugqwala kwayo, iyenze ifanelekele ukusetshenziswa ezindaweni ezinokhahlo.
Ngaphezu kokwakheka kwe-alloy, ukwelashwa okungaphezulu kwezinsimbi zensimbi eziyindilinga nakho kudlala indima ebalulekile ekumelaneni nokugqwala kwayo. Ibha yensimbi eyindilinga eyakhiwe ingena inqubo ethile yokukhiqiza ukuze iqhubeke nokuthuthukisa ukumelana nokugqwala kwayo. Ngezinqubo ezifana nokwelashwa kokushisa nokumbozwa kwendawo, ukumelana nokugqwala kwale migoqo yensimbi kuthuthukiswa kakhulu, okuyenza ifanelekele uhla olubanzi lwezinhlelo zokusebenza, okuhlanganisa izindawo zasolwandle nezimboni.

Kuyaphawuleka ukuthi nakuba ibha eyindilinga yensimbi eyingxubevange ngokuvamile inokumelana nokugqwala okuhle, ingase ibe lula ezinhlotsheni ezithile zokugqwala, ikakhulukazi ezindaweni ezigqwalile. Ngakho-ke, ukugcinwa okufanele nokuhlolwa okuvamile kubalulekile ukuze kuqinisekiswe ukusebenza kwesikhathi eside kwale migoqo yensimbi.
Kafushane, ukumelana nokugqwala kweingxubevange steel imigoqo roundnjengebha eyindilinga yensimbi engu-4140, ibha eyindilinga yensimbi engu-42CrMo4, ibha eyindilinga ye-AISI 4140, ibha yensimbi eyindilinga eyakhiwe, njll. ithonywa yizici ezifana nokwakheka kwe-alloy nokwelashwa kwendawo. Ngokuqonda lezi zici nokukhetha ibha eyindilinga elungile yohlelo lokusebenza oluthile, izinkampani zingaqinisekisa ukusebenza okuthembekile nokuhlala isikhathi eside ezindaweni ezigqwalile.
