Te kawe i te kirikiri rino mo te tapahi kohatu me te ora roa
Whakaahuatanga Hua
He mea hanga te kirikiri rino ki te koranu chrome he mea tere te ngota i muri i te rewa. I muri i te maimoatanga wera, ka whakaatuhia me nga ahuatanga miihini tino pai, te kaha pai, te kaha o te ngenge, te roa o te mahi, te iti o te kai me era atu. 30% ka tiakina. Te nuinga whakamahia i roto i te tapahi granite, sandblasting me te pere peening.
He mea hanga te kirikiri rino ki te rino waro koranu rino, ka whakamahia ki te hanga poroporo, roera me nga mowhiti kawe. He teitei me te rite te pakeke o te kawe rino me nga wa huringa teitei, me te elasticity teitei. Ko te riterite o te hanganga matū, te ihirangi me te tohatoha o nga whakauru kore-metallic me te tohatoha o nga carbide o te rino e mau ana he tino kaha, koinei tetahi o nga whakaritenga nui i roto i nga mahi maitai katoa.
Kei roto i te kirikiri rino he whakarewa utu nui - chromium, na roto i te mahinga hanga ahurei, te hanganga metallographic tino pai, nga matūriki hua katoa, te pakeke o te ahua, te wa huringa teitei, ka taea te whakapai ake i te tere whakaora (he kaha te mahi o te kirikiri ka whakaheke haere), na te mea ki te whakaiti i te auau kohi o te abrasive ki runga ki te 30%.
Apure Tono
Te kawe i te kirikiri rino mo te kirikiri kirikiri
Ko te kawe i te kounga kirikiri rino e whakamahia ana mo te wahanga kirikiri kirikiri e pa ana ki te kounga me te utu matawhānui mo te pai o te pupuhi kirikiri, te whakakikorua o te kirikiri, te peita, te kaha o te hiko me te kai abrasive. Na te tukunga o te paerewa whakamarumaru whakamarumaru hou (PSPC), he nui ake te tono mo te kounga o te kirikiri kirikiri. Na reira, he mea nui te kounga kirikiri maitai i roto i te pupuhi kirikiri.
Kohanga koki mo te Ipu kirikiri
Ko te kirikiri kirikiri koki e pupuhi ana ki runga i te tinana pouaka ipu i muri i te wea. Whakapaihia te hononga paiherea me te wa ano ki te hanga i te mata o te pouaka tinana ki etahi taratara me te whakanui i te pānga peita anti-corrosion, kia taea ki te mahi mo te wa roa i waenganui i nga kaipuke, te tahuhu, te waka utanga me nga waka tereina.
kirikiri maitai koki mo Te parae hiko taputapu kirikiri kirikiri.
Ko te hua hiko mara te tono motuhake mo te taratara me te ma o te maimoatanga mata. Whai muri i te maimoatanga o te mata kirikiri rino koki, me pa ki nga momo huringa huarere ki waho mo te wa roa. Na, ko te pupuhi kirikiri koki mo te mata he mea tino nui.
Te tapahi kirikiri kirikiri maitai me te kirikiri tapahi kohatu
Ki te tapahi kohatu ma te whakamahi i te kirikiri kirikiri kirikiri me te kirikiri tapahi kohatu mai i te rere rere wai. I roto i te tukanga o te tapahi, karekau he huringa matū, karekau he painga o te kore aroha ki te matū me te mahi a tinana o nga taonga kohatu, kaore he wera o te wera, he whaiti, he tino tika, he maeneene te mata tapahi, he ma me te kore poke, etc.
Kiriata koki maitai mo nga Locomotives te pupuhi kirikiri
I muri i te whakaoti i te hangahanga, i te whakahou ranei, me peita te mata o te locomotives (tae atu ki te koti o raro, te paninga waenganui, te paninga whakaoti me etahi atu), hei whakapai ake i te ahua o waho me te oranga mahi. Ko te kowhiringa o te Grit angular angular he mea tino nui ki te maimoatanga o te mata, e pa ana ki te mahi o te paninga o te anti-kapiti, te aukati urunga me te inoxidizability.
kirikiri maitai koki mo Te hanganga maitai
Ki te hanganga maitai, ko te tere o te waikura te nuinga e pa ana ki te haumanu o te hau me te hanganga me te nui o te parahanga i roto i te hau. Kia roa ake ai te ora o te ratonga, me hiahia te anga maitai angular koki kirikiri kirikiri maimoatanga mata, katahi ma te rehu ki te hanga i te kiriata whakamarumaru i runga i te mata whakarewa hei aukati me te whakaiti i te waikura whakarewa.
Kaihanga Kiriata Tiro mo te Miihini Tauranga onepu
Ko te hanga wapu whanga he whakamahi nui i te hanga maitai. Na reira, he tiketike rawa te tono anti-corrosion hanganga maitai. He maha nga wa e pa ana nga miihini whanga ki etahi taiao motuhake. Hei tauira, ko te taiao hau moana makuku, na te mea ka pakaru te hanga o nga hanganga rino. I tera keehi, ka hiahiatia te pupuhi kirikiri me te paninga hei tiaki i nga miihini whanga. Na he mea tino nui te hanga o te kirikiri maitai.
