Ekwelapheni ukushisa kokubumba, ngenxa yamandla amakhulu esithandweni sokushisa kanye nesikhathi eside sokufakelwa amandla, ukusetshenziswa kwamandla kukhulu kuyo yonke inqubo, esikhathini eside, indlela yokulondoloza amandla ekwelapheni ukushisa kokubumba kube yinkinga enzima.

Okubizwa ngokuthi "i-insulation zero" quenching, iwukukhomba ukushisa okukhangayo, indawo yayo kanye nomgogodla ukuze kufinyelele izinga lokushisa lokushisa elicishayo, akukho ukwahlukanisa, ukucisha ngokushesha inqubo yokupholisa. Ngokusho kwenkolelo yendabuko ye-austenitic, ukukhwabanisa kufanele kube nesikhathi eside sokufakelwa kwenqubo yokushisa, ukuze kuqedele ukuxutshwa nokukhula kwezinhlamvu ze-austenisoal restiation, i-austenisoal reg, of austenitic.Ubuchwepheshe obukhona bokucisha nokushisa kwama-forgings bukhiqizwa ngaphansi kokuqondiswa kwale mbono.Uma kuqhathaniswa nenqubo yamanje yokucisha, "ukugcinwa kokushisa kwe-zero" ukucisha kusindisa isikhathi sokugcinwa kokushisa okudingwa yi-homogenization yesakhiwo se-austenitic, hhayi nje kuphela kungasindisa u-20% -30% wamandla, kuqede futhi ukukhiqizwa kwe-30% kunganciphisa noma kunciphise ukukhiqizwa kwe-302%. i-oxidation, i-decarbonization, i-deformation nokunye, okuhambisana nokuthuthukiswa kwekhwalithi yomkhiqizo.

Uma insimbi ye-carbon steel nensimbi ephansi ye-alloy ishiselwa ku-Ac1 noma i-Ac2, inqubo ye-homogenization ye-austenite kanye nokuqedwa kwe-carbides ku-pearlite kuyashesha.Lapho usayizi wensimbi uyingxenye yobubanzi bengxenye encane, ukubalwa kwesikhathi sokushisa akudingi ukucabangela ukufakwa kwe-thermal, okungukuthi, ukufeza i-zero thermal insulation kuno-4 ubukhulu bensimbi uma umsebenzi ucisha. I-100mm, ukushisa esithandweni somoya, izinga lokushisa elingaphezulu kanye nomgogodla cishe lifinyelelwe ngesikhathi esifanayo, ngakho-ke isikhathi salo somfaniswano singanakwa, uma kuqhathaniswa nenqubo yokukhiqiza yendabuko (r = aD) ene-coefficient yokushisa enkulu, ingancishiswa cishe ngo-20% -25% ukucima isikhathi sokushisa.

Ukuhlaziywa kwethiyori kanye nemiphumela yokuhlola kubonisa ukuthi kungenzeka ukusebenzisa "ukufakwa kwe-zero" ekucimeni nasekushiseni okujwayelekile kwensimbi yesakhiwo.Ikakhulukazi, i-45, 45 mn2 carbon structural steel noma i-single element alloy structural steel, ukusetshenziswa kwenqubo ye-"zero insulation" kungaqinisekisa izakhiwo zemishini yezidingo; Ukushisa kwe-"zero insulation" kunokushisa kwendabuko kungasindisa isikhathi sokushisa esingaba ngu-50%, ukonga amandla okuphelele kwe-10% -15%, ukuthuthukisa ukusebenza kahle kwe-20% -30%, ngesikhathi esifanayo "i-insulation ye-zero" yokucisha isiza ukucwenga okusanhlamvu, ukuthuthukisa amandla.
