Kungani ukwelashwa ukushisa kuyadingeka ukuze machining?

I. KunganiinsimbiUkwelashwa kokushisa Uma sikhuluma ngokwelashwa kokushisa kwensimbi, awukwazi ukuzungeza insimbi, okuyinsimbi eningi kakhulu emhlabeni wethu kanye nensimbi esetshenziswa kakhulu.Insimbi ehlanzekile ibhekisela kokuqukethwe kwekhabhoni engaphansi kuka-0.02% yensimbi yensimbi, iyinsimbi eguquguqukayo ne-ductile esiliva-emhlophe, ine-conductivity enhle kazibuthe, esetshenziswa ikakhulukazi ohlelweni lwamajeneretha kanye ne-motor iron core.Insimbi igama elijwayelekile le-iron-carbon alloy, iphesenti le-carbon mass liphakathi kuka-0.02% no-2.11%, ngokuvamile sisebenzisa ucezu lwensimbi yensimbi, cishe zonke ziyinsimbi.Okuqukethwe kwekhabhoni kungaphezulu

I-2.11% ibizwa ngokuthi i-pig iron, i-brittle futhi iqinile, ukusebenza kahle kokucubungula, ukukala isisindo esinesisindo esiningi senziwe ngensimbi yengulube.Ngaphandle kokwelashwa kokushisa kwensimbi, amandla ensimbi nensimbi yengulube, ukuqina kanye nokuqina kwendawo, ukumelana nokugqwala nezinye izakhiwo, kunzima ukuhlangabezana nezidingo ezahlukene zokuphila kwethu kwangempela.Ngakho-ke, abantu bahlukumeza ubuchopho babo futhi baqhubeka behlola, futhi ngaphezu kokukhethwa okunengqondo kwezinto kanye nezinqubo ezihlukahlukene zokwakha, kwakukhona ukwelashwa kokushisa.Ngakho-ke, ukwelashwa ukushisa iwukuba ukwenza workpiece metal ne edingekayo izakhiwo mechanical, izakhiwo ngokomzimba kanye izakhiwo amakhemikhali, kuyindlela ephumelelayo ukuthuthukisa ukusebenza metal workpiece.

II.Yini insimbiukwelashwa ukushisa

Futhi kuyini ukwelashwa ukushisa?

Ukwelashwa kokushisa kwensimbi kuyinqubo yokushisisa insimbi noma i-alloy workpiece endaweni ethile iye ezingeni lokushisa elifanele futhi igcinwe kuleli zinga lokushisa isikhathi esithile, bese ipholiswa ngendlela ehlukile ngesivinini esihlukile, ukuze uguqule isakhiwo se-microstructure. ebusweni noma ngaphakathi kwensimbi ukuze ulawule izakhiwo zayo.
