Izinkinga ezijwayelekile kanye nezindlela zokwelapha ze imishini yokuqeda imvamisa ephezulu ama-ingots nemigoqo

1. I-Decarbonization

I-Decarburization ibangelwa ikakhulukazi ukuchithwa kwempahla eluhlaza ngokwayo kudlula izidingo zokucubungula. Ngakho-ke, kufanele siqinise ukuhlolwa kwekhwalithi yezinto ezingavuthiwe ngaphambi kokwelashwa kokushisa.

Okwesibili, i-microstructure ayifaneleki (inaliti ecishiwe ye-martensite iwugqinsi) Lesi sici sibangelwa ikakhulukazi ukushisa okuphezulu kokushisa. Ngakho-ke, ohlelweni lokwelapha ukushisa kusetshenziswa isithando somlilo sokucisha imvamisa ephezulu, kufanele sinciphise ngokufanelekile izinga lokushisa lokushisa ukuze siqinisekise ukuthi izinga lokushisa lokushisa lihlangabezana nezidingo.

3. Ukuguquguquka ngenxa yokubekezelelana Izimbangela nezinyathelo zokuvimbela zimi kanje:

1. Ukunciphisa ingcindezi akwanele. Ngakho-ke, kufanele sisebenzise isithando somlilo se-high-frequency quenching ukuze uthole ukwelashwa okwanele kokuthungatha. Kuyanyakazisa ngesikhathi sokushisisa noma ukupholisa, ngakho-ke, kufanele siqinisekise ukuthi isiqeshana sokusebenza singena endaweni yokupholisa sibheke phezulu uma sisebenza ukuze sinqande ukungqubuzana kwe-spindle nezinye izinto.

2. Uma izinga lokushisa langaphambi kokushisa lingalingani noma isikhathi sifushane, kufanele sikhethe ngokunengqondo isithando sokushisa esinokushisa okuhle okufanayo, futhi isikhathi sokushisa kufanele sanele.

4. Ubulukhuni obuphansi noma ubulukhuni obungalingani

Izizathu zalesi sici kanye nezinyathelo zayo zokuvimbela zimi kanje: Ukushisa kokucisha kuphansi noma isikhathi sokushisa sifushane, kufanele sisebenzise ngokuqinile izidingo zemingcele yenqubo yokushisa ukushisa. Isivinini sokupholisa siyanensa noma indawo yokupholisa ayifaneleki. Ngakho-ke, ngesikhathi sokwelashwa kokushisa okucishayo, kufanele sikhethelwe ngokushesha Izingxenye ukuze zicinywe ngokwezinga ukuze kugwenywe isikhathi sokupholisa komoya esiningi, futhi kukhethwe indawo yokupholisa efanele.

5. Ukwephuka

Izizathu zokukhubazeka kokuphuka kanye nezinyathelo zabo zokuvimbela zimi kanje: Izinga lokushisa lokucisha alivamile, ngakho-ke lapho sisebenzisa isithando somlilo sokucisha imvamisa yokucisha ukwelashwa kokushisa, kufanele sisebenzise ngokuqinile izidingo zenqubo yokwelapha ukushisa. Ukuhlelwa kwempahla eluhlaza akufanelekile, ngakho-ke, kufanele sihlole ukuhlelwa kwezinto ezingavuthiwe ukuze siqinisekise ukuthi ziyahlangabezana nezidingo ngaphambi kokuthi zifakwe ekukhiqizeni.
