Raina kowiri tira me te ripinga (CAPL)

I whakataka-matao ahau he kowiri tira kowiri tira me te raina pickling

Ka taea te wehea te piro makariri me te mahi annealing o te kowiri tira ki te pickling annealing takawaenga me te pickling annealing kua oti. Ko te kaupapa matua ko te rerystallize te kowiri tira makariri-hurihia i muri i te annealing ki te whakakore i te whakapakeke mahi, kia rite ki te whakatutuki i te kaupapa o te whakangohe me te whakapai ake i nga taonga miihini. Ka whakamahia te Piki ki te whakakore i nga poke penei i te tauine waikura rino i mahia i roto i te mahi whakaene me te whakapai ake i te kounga o te mata o te riu.

Ko nga ahuatanga matua o te waahanga:

Nga momo rauemi mata: Korekore te tira CrAISI200/300/400 kua whakataka makariri

Nga whakaritenga rauemi mata: 0.2-2.0mmX800-1600mm

Wae tukanga tere: 80-130mpm

Te kounga o te hua: 2B, i roto i te raina me te JISG4304 me GB4237-2007

Wāhanga oumu Annealing: Tautuhia te waahanga whakamahana me te wahanga whakawera o te hau maaori ki te whakakotahi, me te whakanoho i te whakawhiti wera o te hau ki te whakamahana i te hau wera, he pai te whakamahana me te whakamahi wera.

Te tukanga īkara: Mo te kowiri tira austenitic kua hurihia makariri: te tote electrolysis (Na2SO4) + te waikawa whakauru (HNO3+HF) pickling

Mo te rino kowiri tira ferritic me te martensitic: Te tote electrolysis (Na2SO4) + waikawa nitric (HNO3) pickling electrolytic

Pūnaha whakahaere hiko: Whakatauhia te SIEMENS AC auau huringa tere mana whakahaere mana whakahaere, me te atanga tangata-miihini pai me te tiaki taputapu ngawari.

Aunoa Ahumahi: whakamahia te punaha SIEMENS mo te whakahaere aunoatanga.

Ko te rere o te tukanga matua ko:

Te wetewete, te welding, te annealing, te whakamatao, te tiki, te horoi, te whakakoi-iti, te kowiri

II kowiri tira wera-whakatakahia te raina whakahiato me te raina pickling

Ko te waeine kowiri tira wera-whakatakahia me te taputapu pikau he mahi whakaene, pakaru me te tiki. Ko te nuinga o te waa ki te whakahou i te kowiri tira wera i muri i te whakakii ki te whakakore i te whakapakeke o te mahi, kia tutuki ai te kaupapa o te whakangawari me te whakapai ake i nga taonga miihini. Ka whakakorehia e te Pika nga poke penei i te tauine waikura rino i mahia i roto i te mahi whakaene, ka whakapai ake i te kounga o te mata o te rino takai, he pai hoki ki te mahi hurihuri makariri.

Ko te kaha o te hanga i hangaia he 150,000-300,000 tons / tau, ko te momo rauemi mata ko te 200/300/400 raupapa kowiri tira (i runga i te paerewa GB / T709), ko te 1000-1350mmX2-3mm te tohu, me te tere hoahoa o te Ko te waahanga tukanga o te waahanga ko Max.50m / min. I roto i te wahanga tukanga o te waeine, ka oti te nuinga o nga mahi whakahiato, pakaru ūkuikui me te tiki. Ko te kounga o te hua ka rite ki nga paerewa JISG4304 me GB4237-92.

Ko nga ahuatanga matua o te waahanga:

Whakapaia te hangarau whakangao matatau ki te whakakotahi i te annealing, te pakaru o te ūkuikui me te pikau hei whakarite i te kounga o te hua.

Te waahanga o te oumu: Ko te waahanga whakamahana me te waahanga whakawera tika o te hau ka whakauruhia, ka tukuna he kaitahuri wera hau ki te whakamahana i te hau wera, ka pai ake te pai o te whakamahana me te tere o te whakamahi wera.

Po Lin pupuhi pupuhi: I muri annealing, te tikanga whakakotahi o te toia me te whakatika i te ūkuikui me te pupuhi pupuhi ka tangohia, e taea te tango me te whakangaro i te hanganga tauine waikura rino, me te whakahaere i te maimoatanga pickling.

Te tukanga īkara: Ko te wāhanga pīkara ka tango i mua i te horoi, te waikawa sulfuric acid electrolytic pickling, te waikawa whakauru (HNO3+HF) te pikau me nga tukanga horoi cascade ki te whakarite i te painga o te pickling.

Pūnaha whakahaere hiko: Whakatauhia te SIEMENS AC auau huringa tere mana whakahaere mana whakahaere, me te atanga tangata-miihini pai me te tiaki taputapu ngawari.

Aunoa Ahumahi: whakamahia te punaha SIEMENS mo te whakahaere aunoatanga.

Whakahaerehia te huringa:
