He uaua nga take kapiti o te mate whakakai, a me tino tātarihia.Engari ka taea te whakarapopototia ko nga take e whai ake nei.
1. Ko nga mea e whakamahia ana i roto i te mowhiti mowhiti ko tetahi o nga take nui.I tenei wa, ko te 4Cr13 me te 20CrMnTid te nuinga e whakamahia ana i roto i to tatou whenua, he ahua pumau.Engari he rereke te kaihanga rauemi, mo te mea ano, ka whai waahi nga waahanga tohu, ka pa ki te kounga o te mowhiti mowhiti.
2. Te mahi hangai.He hononga nui tenei i roto i te mahi hanga pokepokea ai.Mo te koranu maitai koranu teitei, ko nga whakaritenga o te tohatoha carbide rauemi me etahi atu hanganga metallographic ka tukuna ki mua.He mea tika ano kia kaha te whakahaere i te awhe o te whakamahana whakawera, te whakatakoto i nga whakaritenga whakamahana tika, te whakamahi i te tikanga whakamaarama tika, me te puhoi te whakamahana i te wa tika ranei i muri i te hanga.Ko te tukanga kore-paerewa he ngawari ki te arahi ki te pakaru o te tinana mate mowhiti.
3. Whakaritea mo te maimoatanga wera.E ai ki nga momo rauemi me nga whakaritenga o te mate, te whakahiato, te whakamaarama me etahi atu tukanga maimoatanga wera hei whakapai ake i te hanganga, te whakakore i nga hapa o te hangahanga me te waatea, ka pai ake te mahi.I muri i te whakarite tika te maimoatanga wera o te waro waro koranu maitai mate, ka taea te whakakore i te carbide whatunga, ka taea te hanga i te carbide spheroidized me te para, a ka taea te whakatairanga i te tauritenga tohatoha o te carbide.He pai tenei ki te whakarite i te tinei, te whakamaarama i te kounga, te whakapai ake i te oranga o te miihini.
mira pellet mate maimoatanga wera
1. Te tineia me te whakama.Koinei te hononga matua mo te maimoatanga wera mate.Mena ka puta te wera nui i te wa e whakamahana ana, ehara i te mea ka nui ake te pakaru o te mea mahi, engari he ngawari hoki ki te paheketanga me te pakaru i te wa e whakamahana ana, ka tino pa ki te oranga o te miihini.Ko te whakaritenga o te maimoatanga wera me tino whakahaere me te tango i te maimoatanga wera korehau.Me mahi i roto i te wa i muri i te tinei, a kia rite ki nga whakaritenga hangarau ki te tango i nga tikanga rereke rereke.
2. Stress-relieving annealing.Ko te mate me tuku ki te whakamaarama whakamaarama i muri i te miihini taratara, kia whakakorea ai te ahotea o roto na te miihini taratara, kia kore ai e nui te rerekee, kapiti ranei na te tineia.Mo te mate me te nui o te hiahia, me uru ano ki te maimoatanga whakamarumaru whakamarumaru i muri i te huri, he pai ki te whakapumau i te tika o te mate me te whakapai ake i te oranga ratonga.
Ko te whakatuwheratanga o te kohao reiti o te mowhiti mate
Mena he tiketike rawa te reiti o te kohao tuwhera o te whakakai, ka piki ake pea te pakaru o te mowhiti.Na te rereke o te taumata maimoatanga wera me te tukanga, ka puta he rereketanga nui i waenga i ia kaihanga mate mowhiti.Ko te tikanga, ka mate to tatou mira pire ka taea te whakapai ake i te reiti o te kohao tuwhera ma te 2-6% i runga i te ahua o te miihini o te karaehe tuatahi o te whare, a ka taea te whakarite i te oranga o te miihini mowhiti.
Te kakahu mate mira pellet
etahi matotoru me te kaha ka heke ki te waahi kaore e taea e ia te kawe i te pehanga o te granulation, ka pakaru.E taunaki ana kia mau te mate whakakai ki te taumata e rite ana ki te riu anga roera whakarara, me whakakapi te mate whakakai i te waa.
Ka mate te mira pire i roto i te tukanga o te granulation, te nui o te rauemi ki roto i te mira pire mate e kore e taea te rere i te 100%.Ahakoa he tiketike te tukunga granulation mate mowhiti, engari he wa roa o te mahi kaha nui, ka hoki. arahi ki te pakaru o te mate whakakai.Ka tūtohu matou ki te whakahaere i te 75-85% o te kawenga ki te whakarite i te oranga ratonga o te mowhiti ka mate.
Mena ka mate te mowhiti, ka pehia rawatia te pukapuka perehi, he ngawari te pakaru.Ko te tikanga, me whakahaere te tawhiti i waenga i te mowhiti me te pukapuka perehi i waenga i te 0.1-0.4mm.
maha
He ngawari te pakaru ina puta nga mea pakeke penei i te rino i roto i te papanga pelleting.
Te whakaurunga o te mowhiti mate me te miihini pelleting
Ko te whakaurunga o te mowhiti mate kaore i te piri, ka puta he waahi i waenga i te mowhiti me te miihini pelleting, a ka puta ano te pakaru o te mowhiti i roto i te tukanga o te pelleting.
I muri i te maimoatanga wera, ka mate te mowhiti ka tino rerekee.Ki te kore e whakatika, ka ngatata te mate whakakai i te wa e whakamahia ana.
Ina he koha te miihini pelleting ake, penei i te rakau matua o te miihini pelleting e wiri ana.
