deoxidizer i ka honi

Nā Deoxidizers i ka welding: He alakaʻi piha ʻO Deoxidizers i ka wiliwili he mea koʻikoʻi no ka hōʻoia ʻana i nā welds kiʻekiʻe ma o ka wehe ʻana i ka oxygen dissolved a me nā haumia ʻē aʻe mai ka metala i hoʻoheheʻe ʻia. Huli kēia alakaʻi i nā ʻano like ʻole deoxidizers i ka wiliwili, kā lākou mau noi, a me nā hana maikaʻi loa no kā lākou hoʻohana ʻana.

Ka hoʻomaopopo ʻana i ke kuleana o nā Deoxidizer i ka welding

Hiki ke hoʻoheheʻe ʻia ka oxygen i loko o ka metala weld i hoʻoheheʻe ʻia ke kumu o ka porosity, ka haki ʻana, a me ka hōʻemi ʻana i nā waiwai mechanical. Deoxidizers i ka wiliwili e hana me kēia mau mea haumia i hoʻoheheʻe ʻia, e hana ana i nā oxide paʻa e lana ana i ka ʻili o ka loko wai weld, e waiho ana ma hope o ka metala ʻoi aku ka maʻemaʻe. ʻO ke koho o deoxidizer pili i ka metala kumu, kaʻina hana kuʻi, a me nā waiwai weld i makemake ʻia.

Nā ʻano Deoxidizer

Hoʻohana maikaʻi kekahi mau mea waiwai deoxidizers i ka wiliwili. Eia nā laʻana maʻamau: Silicon (Si): He mea hoʻohana nui ʻia deoxidizer, ʻoi aku ka maikaʻi ma nā kila. Hoʻokumu ia i ka silica paʻa (SiO2), e hoʻokaʻawale maʻalahi mai ka metala hoʻoheheʻe. ʻO ka nui o ka silika i hoʻohui ʻia e pili ana i ka ʻike o ka oxygen a me ka maikaʻi weld i makemake ʻia. Manganese (Mn): ʻO kekahi mea maʻamau deoxidizer, hoʻohana pinepine ʻia me ka silika. Paʻa nō hoʻi nā ʻokikene manganese a hiki ke hoʻokaʻawale ʻia mai ka wai weld. Aluminum (Al): He mea ikaika ka Aluminum deoxidizer, hana alumina (Al2O3). He mea maikaʻi loa ia i ka wehe ʻana i ka oxygen mai nā alumini alumini a me kekahi mau kila kūikawā. Titanium (Ti): He ikaika ka Titanium deoxidizer ʻoi aku ka maikaʻi ma nā haʻahaʻa haʻahaʻa. Hoʻohana pinepine ʻia i nā noi welding kiʻekiʻe e koi ana i ka kūpaʻa weld. ʻO Ferroalloys: ʻO kēia nā mea hoʻohui i loaʻa ka nui o nā mea deoxidizing e like me ke silika, manganese, aluminika, a me ka titanium. Hāʻawi lākou i kahi ala kūpono e hoʻolauna i nā deoxidizers i ka manawa like.

Ke koho ʻana i ka Deoxidizer kūpono

ʻO ke koho o ka mea maikaʻi loa deoxidizer mea koʻikoʻi no ka loaʻa ʻana o ka maikaʻi weld i makemake ʻia. ʻO nā kumu e noʻonoʻo ai: ʻO ka Metala Kumu: Loaʻa i nā metala kumu ʻokoʻa nā pilina like ʻole no ka oxygen, e koi ana i nā deoxidizers a me nā ʻokoʻa. Ke Kaʻina Hana Hana: ʻO ke kaʻina hana kuʻi (e like me Gas Metal Arc Welding (GMAW), Gas Tungsten Arc Welding (GTAW), Shielded Metal Arc Welding (SMAW)) e hoʻopili i ke kiʻekiʻe o ka hoʻoheheʻe ʻana o ka oxygen a, no laila, nā koi deoxidizer. Nā Waiwai Weld i makemake ʻia: ʻO nā waiwai mechanical e pono ai, e like me ka ikaika tensile a me ka ductility, e kuhikuhi i ka mea kūpono. deoxidizer a me kona noonoo.

ʻO nā hana maikaʻi loa no ka hoʻohana ʻana i nā Deoxidizer

Ka lawelawe pono a me ka hoohana ana o deoxidizers i ka wiliwili he mea nui no ka hopena maikaʻi. ʻO nā hiʻohiʻona koʻikoʻi: ʻO ke ana pololei a me ka hoʻohui: Ka mana pololei i ka nui o deoxidizer Hoʻohui koʻikoʻi e pale i ka deoxidation nui, hiki ke alakaʻi i nā hopena makemake ʻole. Huipui Pono: Huipuia pono o ka deoxidizer i loko o ka wai hoʻoheheʻe weld e hōʻoia i ka deoxidation like. Koho Flux: Hiki i ka flux kūpono ke hoʻonui i ka pono o ka deoxidizer ma ka hoʻomaʻamaʻa ʻana i ka wehe ʻana o nā oxides. Ka nānā ʻana ma hope o ka weld: Pono ka nānā ʻana i nā hiʻohiʻona a me ka hoʻāʻo ʻole luku (NDT) e hōʻoia i ka maikaʻi o ka weld a hōʻoia i ka lawa ʻana o ka deoxidation.

Nānā Hiʻohiʻona a me nā Laʻana

[E loaʻa i kēia ʻāpana nā hiʻohiʻona maoli o nā noi deoxidizer like ʻole i nā hiʻohiʻona wili like ʻole. Hoʻopili ʻia nā kikoʻī kikoʻī e pili ana i nā ʻano weld, nā metala kumu, nā deoxidizer i koho ʻia, a me nā hopena. Pono kēia i ka noiʻi nui a hiki i ka loaʻa ʻana o ka ʻikepili proprietary.]

Ka hopena

ʻO ka hoʻohana kūpono o deoxidizers i ka wiliwili mea nui no ka loaʻa ʻana o nā welds kiʻekiʻe. ʻO ka hoʻomaopopo ʻana i nā ʻano deoxidizer, ke koho ʻana i ka mea kūpono no ka noi kikoʻī, a me ka hahai ʻana i nā hana maikaʻi loa he mea koʻikoʻi ia no ka hōʻoia ʻana i ka pono weld a me ka holomua o ka papahana holoʻokoʻa. No nā mea pili kiʻekiʻe kiʻekiʻe e pili ana i nā noi wili, e noʻonoʻo e ʻimi i nā makana mai Inner Mongolia Xinxin Silicon Industry Co., Ltd.

Deoxidizer	Pono	Nā pōʻino
Silika	Kūʻai-pono, loaʻa ākea	Pono paha i nā manaʻo kiʻekiʻe
Manganese	Pono i ka hui pū ʻana me ke silika	Hiki ke kōkua i ka hoʻokomo ʻana i ka sulfide
Aluminum	Hana maikaʻi loa, ʻoiai ma nā haʻahaʻa haʻahaʻa	Hiki ke hana i ka porosity inā ʻaʻole i mālama pono ʻia
