Waea waikura: ngā momo taketake, tohu me te whakamahi o

ti'a ia tatou ia kaipūkaha Harry Brearli taeraa mai o kowiri tira. Tāpiri i te huānga whakarewa matū i huaina chromium, tamata ia ki te whakatutuki i hua o te pāmahana rewa. hiahiatia ana tēnei te ki te whakapai ake i te mahi o oko, pū. I roto i enei ngā i kitea ai e he rerekētanga rite whakaritea ki ētahi atu te koranu hua. ngā ratou i roto i te resistance matū. puta tenei e tika ana ki te hanganga i runga i te mata o te kiriata o chromium waikura.

timata rangahau he kowiri tira i roto i te tau 1871, ka rēhita te ārai tuatahi i anake i roto i te 1913. Ko te ōrite hou o kowiri tira e tutuki nga whakaritenga katoa mō ngā āhuatanga kaha me te matū, i whiwhi i te tau 1924, pūtaiao i whānau Hartfield.

Ko te whakaaro matua o te tira

Ko te tohutoro tuhinga ranei te tahi atu maitai waikura-ātete kua te momotuhi whai ake: "kōeke maitai 08H18N10". tikanga o tēnei i te roto ihirangi o te huānga e whai ake nei:

• carbon - e kore neke atu i 0.8%;
• chromium - 18%;
• nika - 10%.

Tenei huānga matū taketake, engari ano hoki i roto i te koranu me era atu poke, e kore te mea neke atu i te 1% ratou ihirangi ōrau.

Ko te hua kowiri tira matua

Hanga o kowiri tira hua-te kounga teitei pērā i:

• waea rino waikura kore;
• whārangi maitai ;
• putorino o thicknesses taiepa rerekē, me te diameter roto;
• tuhinga ahuahu.

Hoki e hanga maha maripi whare me pūtukatuka kai kōpuku i tenei rauemi ngā.

Stainless Steel Waea

Ka rite ki tetahi atu waea hua maitai hua rite ki te paerewa Russian nāianei.

regulates te reira i te hanga o taua mea rite waea kowiri, GOST 18143-72. E ai ki tenei tuhinga, kua reira he matotoru o i 0.3 ki te 6 mitamano.

Ka taea te whakamahi i te waea te hunga i te hua whakamutunga, me te taea te tukatuka anō i te niao. Na i roto i o reira, whakapā atu koa:

• hononga mekameka ki te rahi rerekē,
• tukutuku ki te taahiraa rerekē o te pūtau,
• puna.

Cross-wāhanga o te waea, te tikanga a tawhio, engari ka taea e hoki te whakatau e koe whakaaro porotītaha tapawha ranei. Ko te tino whai hua wāhanga porotakaroa ka whakamahi i te rauemi i roto i te tukanga o te fehokotaki'anga o te taua rino waikura kore.

He te painga matua e whai ake nei waea kowiri:

• taumata teitei o te waikura ātete ki te houku, taiao ahumahi pukuriri me te tōhau;
• waea ki te ihirangi tiketike o molybdenum, chromium, nika, parahi, silicon, vanadium he ātete wera tiketike, tika me te mauroa.

Ko te whakamahi o te waea rino waikura kore

Nā ki te ora roa, ātete ki waikawa me te kawakore pāpāho, kua whakamahia whānuitia waea o kowiri tira i roto i te ara e rua:

• pūāhuru i te taura;
• fehokotaki'anga;
• tātari mata whenu.

Waea waikura, te utu o e rerekē i 120 ki te 350 moni ia kirokaramu, i runga i te matotoru me ngā āhuatanga rānei, kua riro te whakamahi whānui i roto i ngā ahumahi pēnei i:

• engineering;
• hiko;
• hinu;
• matū;
• kai.

waea fehokotaki'anga

hiahiatia whanaketanga ahumahi matū Whānui te hanganga o te whakarewa metallurgical e taea o te pupuri āhuatanga aunoa tiketike i roto i ngā taiao ha'iriiri. I tua atu ki te ātete ki ngā āhuatanga matū e hiahiatia ana i roto i te tahi mau ahumahi, me te ara āhuatanga i roto i nei e taea te whakarewa te tu pāmahana tino tiketike. solves kowiri tira tokomaha o nga mahi. Ano, e kore e taea e te whakamahi i roto i te ahumahi kai hei te rauemi rerekē.

Ko te taumata hou o te tukatuka o ngā hua whakarewa āhei ki te whakaputa i ngā hua matatini, engari e kore e taea te mahi i tenei katoa, kahore hononga paiherea. Kei te whakamahia waea he kowiri tira mō ngā hua fehokotaki'anga i roto i nga whakaminenga matatini e E whai wāhi ana ki taiao pukuriri.

Ko te painga matua nohoia e te waea fehokotaki'anga kowiri, he e i roto i te whakamahi i te tui paiherea parakore nui, ki kore slags kino me inclusions parasitics. Na roto i te te whakamahi i kowiri tira rauemi iho he tui o kore e kitea ki te hāora. Utu mo enei painga, ko e te tukanga fehokotaki'anga i roto i tenei take, ko te āhua uaua, me kai - ara.

whakamahia waea he kowiri tira te anake i roto i te fehokotaki'anga aunoa. mahi ia he pūwhāngai aunoa, hoki te whakahaere i te reira.

Ko te rohe pewa tomo te hau paruru e whakakingitia ia nga oxidizers roto i tenei reira ko te prosekanie tui oti, me te hononga o ngā wāhanga katoa.

Ko te waea kakano ia i tukitukia e te roto i te pahū maitai ki te roa tonu o te 50 mita. Ko te diameter toharite o te pahū ko 50 mitamano. Kai ki te hurihanga muka puta waea biasing te coils rua. I roto i te waenganui-tapahia awaawa matahao, ki i reira he he ringa pono he waea, me te whangai i te reira ki te pū fehokotaki'anga. I mua i tona patunga waea kowiri tino horoia o paru me te mea ke.

Māka o te waea fehokotaki'anga

hangaia Waea e awhiowhio matao, me te mahi wera. E rua ngā momo o te pū - noa, me te tiketike. I roto i te take whakamutunga, i muri i tapa i roto i taiapa, te reta P.

E rua tohu matua waea waikura - kāinga me te ke.

te tapa Russian he tirohanga ārepa - 10X17H13M2T. Ko te tikanga i muri o te pukapuka, me tau te tikanga ona ā-hanganga, me te matū hanganga. Whika whakaritea ōrau o te tetahi huānga, me te pukapuka - te huānga ake. tikanga te whakarāpopototanga i runga te rite e whai ake nei:

• 0.1% waro;
• chromium - 17%;
• nika - 13%
• konupora - 2%
• tohu reta T i whakaputaina te waea e te maimoatanga wera.

Ko te tino matatini te paerewa Pākehā, me te e kore tapanga ōrite o paerewa. Ia kaihanga o te maitai arai tona hanganga.
