Igiciro Cyuruganda Cyiza Cyuma Cyuma Cyuma Gishyushye Cyuma Cyuma

Igikorwa cyo kubyara umusaruro ushusheicyumani ihuriro ryingenzi mu gukora ibyuma. Igizwe ahanini na fagitire yicyuma muburyo bukenewe bwa plaque ikoresheje ubushyuhe bwo hejuru. Ibikurikira nintambwe yibanze:

Gutegura ibikoresho bibisi
Ibikoresho bibisi ni icyapa gikomeza cyangwa kirabya, mubusanzwe mm 150-300.
Ubuso bwibisate bukorerwa isuku (urugero, gutwika flame cyangwa gusya imashini) kugirango bikureho inenge nudusembwa kugirango tumenye neza.
Gushyushya
Igisate kigaburirwa mu itanura rigenda kandi rishyuha kugeza kuri 1100-1300 ° C kugirango ugere kuri austenisation no kongera ihindagurika.
Gushyushya igihe nubushyuhe bigomba kugenzurwa kugirango wirinde gushyuha cyangwa gushyuha.
Roughing
Icyapa kizungurutswe mu tubari hagati ya mm 30-50 z'ubugari mu ruganda rusubira inyuma (urugero, urusyo ruri hagati ya ebyiri cyangwa enye).
Nyuma ya buri cyerekezo kizunguruka, amazi yumuvuduko ukabije urashobora gukorwa kugirango ukureho igice cya oxyde.
Kurangiza
Utubari two hagati twinjira mu ruganda rurangiza (ubusanzwe rugizwe na insyo esheshatu cyangwa zirindwi enye cyangwa esheshatu-ndende), aho zigenda zoroha buhoro buhoro kugeza kuntego (urugero, 1,2-25 mm) binyuze mukuzunguruka. Igenzura ryikora ryikora (AGC) hamwe na sisitemu yo kugenzura ibiringiti bikoreshwa kugirango harebwe ibipimo bifatika.
Mugihe cyo kuzunguruka, imizingo isaba gukonjesha no gusiga kugirango wirinde guhindagurika no kwambara.
Gukonja
Sisitemu yo gukonjesha ya laminari ikonjesha byihuse umurongo wibyuma kuva ubushyuhe bwa nyuma (hafi 800 ° C) kugeza ubushyuhe bwicyumba mugenzura umubare wamazi nigipimo cyo gukonja (urugero, 30-50 ° C / isegonda).
Igikorwa cyo gukonjesha kigira ingaruka kuri microstructure (urugero, ferrite na pearlite ratio) hamwe nubukanishi bwa coil.
Coiling
Icyuma cy'icyuma gikomerekejwe muri coil ukoresheje umuzingo wa pinch. Impagarara zigenzurwa hagati ya 100-500 N / mm² kugirango hamenyekane ifarashi ifatanye kandi nta shitingi irekuye.
Ubushyuhe bwo gukonjesha bugenzurwa hagati ya 550-700 ° C kugirango uhindure ibintu.
Nyuma yo gutunganywa
Kuvura isura: Kuvura hejuru harimo gutoragura kugirango ukureho igipimo cya oxyde cyangwa ibifuniko nka galvanizing cyangwa aluminizing.
Annealing: Itezimbere ihindagurika ryibintu (urugero, rerystallisation annealing mbere yo gukonja). Kuzunguruka: Kugabanuka-kugabanya gukuraho ibyuma bitanga umusaruro kandi bigatera imbere kurangiza.
Kugenzura ubuziranenge no gupakira: Tugenzura ibipimo, imiterere yubukanishi, hamwe nubuziranenge bwubuso mbere yo gutekesha, guhambira, no gushyiramo ibicuruzwa dukurikije ibisobanuro byabakiriya.
