Steel 20: GOST, hiʻona, ka waiwai a me ka noi

Pure hao wehewehe aku ma ke kaupalena papa inoa o ka waiwai, e like me ka makua metala a me ka ole o ka mea hoihoi. Akā, ka mea, ua nānā 'oka a i alahula mau Loaʻaʻia, ia mea e pono ai wale nō e hoʻoholo i ka Nine Inch haku mele' ana, a e i ka pololei wela lapaau.

Ka loa, he pono ole mall steels

A pau kila nānā 'ana i ka hao i hao a me ke kila , a he poe lehulehu Mea Maluna. Ua ua hua mai la ia e likeʻole kiko'î: ka Nine Inch haku mele 'ana, manao, maʻiʻo o nā palapala hehee wale, ka ikaika a me ka toughness, kohoʻia, a he nui na mea e ae. ? Ieoaeunoai - ua ka loa, he pono ole i ka hana. Kekahi o ia mau mea i paʻa 'ano a me ka mea interchangeable.

Mall kila 20 pili ana i ka papa o ka meakino-kalapona i ka ferrite-pearlite 'ole. .. Steel quality, 'o ia hoʻi, i ka ho'ēmi i kā ka maʻiʻo o nā palapala hehee wale, ka luaipele a me ka phosphorus. No kapu ma luna o ka weldability. ʻO kaʻoi loa me ka hui pu ana o ka ikaika a me ka ductilityʻo ia ia i versatile mea no ka? Iecaianoaaiiie o ke omo ua olokaaiaʻe māhele malalo i mahope thermomechanical a thermochemical aaioee (cementation kiniki plating a me ka chromium plating).

He iwakalua loaʻa kona hoʻohana

Steel 20, nona ka waiwai hiki ke pēlā nō i loko o ka laula Oeao ma ke kumu o ka Nine Inch-thermal, thermomechanical lapaʻau mea loa I mau hea hana ma ka paipu? Iecaianoaaiiuo e paka māhele me ka paakiki ili, a me ka pahee waena. Kēia hiki ia mau pua, sprockets, hoolilo, hoʻopaʻa, manu'ū, lou, kilo a lahilahi no ka hahiʻana (piliʻike), ai hua pisetakia, a hoʻopaʻa i no ka hoʻopili 'ole-pilikia. Pipe ua hanaʻia, mai ke kila papa ua hoʻohana 'ia no ka EYI o kinoea, mahu, nonaggressive wai a lako ma lalo o ka puʻuwai. Kēia superheater paipu, pipelines, kiʻekiʻe-puʻe ieoaeunoai a me ka Waihona Noʻeau.

Ka kūkuluʻana thermochemical aaioee

Na ia mau momoku ahi ke hoʻololi i ko lakou ano ma ka wela lapaau. Steel papa 20 i maikai ea waiwai, no laila, 'atikala hoomakaukau mea ma kekahi mau ano: ninini, anu, a wela ua hiolo a unuhi. Ma hope o ka loaʻa 'ana o ka' ikamu ma ka hoolei ana ia Nine Inch-thermal lapaʻau hiki ke hoopili. Ke kumu o keia ina hana - e loaa i ka paa Wear, ahu iho i susceptible i ka popopo, ea a me ka pahee waena.

A hiki i keia pau hapa ua waiho ia ma ka kūpono 'ia (obkladyvaetsya maloo carbonaceous waiwai ua waiho ia ma ka gaseous ole kinowai meakino), a laila mālama mai i kekahi mau hola no ma kahi o 1.5 lā ma kiʻekiʻe ana wela. Machining au mamuli i keia wahi e e pau, no ka mea, ma hope o ka mea thermochemical lapaau o ka huina hoonui e, ua i ka 'ole hope loa. Hehee ai saturates ka luna, ahu iho o ka huina hoonui (0.3 e 3.0 mm), niioaaonoaaiii, ma ka hoʻomaikaʻi kona 'ole a me ka waiwai.

Ke kaumaha ma muli o ka hana iapaau ana konohiki ua kapaia: cyanidation (kiniki-plating), carburization (kalapona), chrome (chrome). Kalapona haawi ana i ka ikaika, kiniki - ka popopo ia'ku, chromium, ma ka hou ana i nā mea a pau i heluʻia,ʻo ia ka ili o ke aniani.

ka kūkuluʻana machining

Like ka mua iaoiaeii o aaioee a ua lawe mai wale nō no ka haawi ana i ka paakiki o na luna, ahu iho o ka mea hiki ke hooheheeia, a me ka pahale kohoʻia, thermomechanical aaioee - o kekahi o ka shaping ki ina hana like. kila 20 Ua hiki ke ino me ka wela a me ke anu kaʻina. Aia nā pono a me nā keakea i loko o kēlā me kēia palapala. Akā, ka mea i hoʻohana 'ia ma ke kumu o ka loa makemakeia waiwai.

Hot deformation noi i ka 'atikala me ka pā mānoanoa i oi mamua o 5 mm o. No ka mea i hana'okesaside ka unahiʻole, a me ka decarburization microlayer (undesired 'ole) i ka wa a ka mea hiki ke hooheheeia Ua pii kai iki ana, alaila, e pili ana i kēia' ano o ka ape lahilahi-paʻa māhele mea impractical. Naʻe, ka mea, ua hoʻokahi nui ia Morohiha maluna o anu deformation.

Hou anuanu hana ua noi ia māhele me ka mānoanoa emi o 5 mm o. No ka huʻihuʻi unuhi wale kupono "pahee" ke ano o ke kila. Ma ape metala undergoes nui deformation a me ke kanana nei a. Ua hiki aku i ka mahuahua i loko o kona ikaika, a me ka alo o ka nui stress i loko o ka 'ole. Oia metala no ka mea, o kona lahilahi pā hiki ole e enaena (pana aku au i aiiia, 'ole. E. E hoʻihoʻi aku i ka ia' ole). He oi prone i ka hopena poino a me nā hōʻeuʻeu wahie. Mall kila paipu (kila 20) kekahi mau ano o ka hana, a loaa oaoieei-hiʻona ka heluna o ka palapala noi. Ka mea, i kā lākou mau noho mau hae no ka? Iecaianoaaiiie o kēlā me kēia 'ano o ka paipu, rula, lako a pan.
