Isihlalo esithwala ukukhishwa sishiswa ukushisa nge umshini wokuqina wokufakelwa. Uyini umphumela?

Okuqukethwe kwesihlalo sokukhishwa kuvame ukuba kube yinsimbi engu-45, okumele imelane nokungqubuzana okukhulu ngesikhathi somsebenzi. Ngakho-ke, izidingo zalo ekukhiqizeni nasempilweni ziphakeme ngokwedlulele, ezidinga ukuthi zibe nobulukhuni obuphakeme, ukumelana nokugqoka okuphezulu nempilo ende yokusebenza. Ngalesi sizathu, abakhiqizi abaningi basebenzisa imishini yokuqinisa imvamisa ephezulu ukwelapha ukushisa. Namuhla, ngizokutshela ukuthi injani imiphumela yokwelashwa kokushisa.

(1) Ukushisa okusheshayo kwemvamisa ephezulu yokushintsha kwezinga lokushisa kuzoshintsha izinga lokushisa elibucayi ensimbi, elizokhulisa umugqa we-Ac3. Ngaphansi kwezimo ezijwayelekile, izinga lokushisa lokucisha imvamisa ephezulu likaNombolo 45 ngu-890-930 ℃, futhi kusetshenziswa ukucima amanzi nokupholisa uwoyela. Lapho amanzi ajikelezayo esetshenziswa njengendawo yokupholisa, ukuvikela imifantu, izinga lokushisa elicimayo kumele lehliswe. Inani elinconyiwe lingu-820-860 ℃.

(2) Ushintsho lwesikhathi sokushisa Lapho kusetshenziswa umshini wokuqinisa ngamandla kakhulu ukwelapha ukushisa, ukwandisa amandla okukhipha, ukunciphisa isikhathi sokushisa nosayizi wegebe le-inductor, nokujula kwesendlalelo esiqinile esihlangabezana nezidingo zobuchwepheshe itholakale futhi.

(3) Isakhiwo sokuqala sidinga ukushisa okuphezulu okuvama imvamisa ukwenza ukwakheka kwe-austenite kungalingani, futhi isakhiwo sokuqala sinethonya elikhulu ekwakhiweni kwe-homogenization kwe-austenite. Ngakho-ke, isihlalo esithwala ngokwahlukana kufanele sijwayele ukwenziwa ngaphambi kokucishwa kwemvamisa ephezulu ukwenza Ukwabiwa okufanayo nokuhle kwama-carbide kuzosiza ukuhlanganisa i-austenite ngesikhathi sokushisa okusheshayo, ngaleyo ndlela kugweme imifantu.

(4) Ama-Multi-turn inductor Ukusebenza kahle kokushisa kungathuthukiswa ngokusebenzisa i-inductor yamajika amaningi.
