Carbon steel elbows isimbi pombi fittings inoshandura mafambiro epombi pane kabhoni simbi pombi. Zvigadzirwa zvemagokora simbi yakakandwa, simbi isina tsvina, alloy simbi, inogadzika simbi yakakandwa, kabhoni simbi, isina-iron simbi nemapurasitiki, nezvimwewo; 45 ° gokora, 90 ° gokora uye 180 ° gokora Matatu marudzi emagokora anonyanya kuwanda, uye mamwe abnormal angle elbow akadai 60 ° anosanganisirwawo zvinoenderana nezvinodiwa zvepurojekiti. Maererano nekugadzirwa kwemaitiro, inogona kukamurwa kuva: welding golbow, stamping golbow, kusunda gokora, kukanda gokora, etc. Isu tose tinoziva kuti pakugadzira uye kugadzira carbon simbi elbows, iyo mechanical properties ye carbon steel elbows inoda kufungwa. Saka, nzira yekuvandudza kuoma kwekabhoni simbi elbows? Tataura izvozvo, tinofanira kutaura pamusoro pekugadzirisa kupisa. Ngatidzidzei nezve kurapwa kwekupisa kwekabhoni simbi magokora.
Chekutanga, nei kabhoni simbi magokora achida kupisa kurapwa? Kana zvasvika pakuvandudza ma mechanical properties, isu tose tinoziva: sechikamu chepombi system, kuoma kwegokora hakufaniri kunge kwakanyanyisa, kuoma kwakanyanya hakubatsiri kuchengetedza deformation simba, uye zviri nyore kuputsa; iyo plasticity haina kunyanya kunaka, nekushandiswa kwenguva. Nekuwedzera kwe, deformation yegokora ichawedzera zvishoma nezvishoma, kuderedza kugadzikana kwepombi system. Kurapa kwekupisa inzira iripo yekuwana simba rakakwana, kuoma uye kuoma kwepurasitiki.

Uye normalizing inogona kugadzirisa dambudziko iri zvakanaka. Normalizing inzira yekupisa yekupisa iyo iyo inopisa-yakadzvanywa gokora inodziya pamusoro peiyo yakakosha tembiricha uye yozotonhodzwa mumhepo. Munguva iyi, iyo isina kuenzana martensite chimiro chinoshanduka zvishoma nezvishoma kuita yunifomu austenite chimiro. Muchiitiko ichi, Mutadzi we brittleness uye kuoma - reticulated cementite inonyangarika muhuwandu hukuru, zviyo zvakakora zvinonatswa, kuoma uye mapurasitiki akanyatsogadzikana, uye yakazara mechanical properties inovandudzwa. Naizvozvo, zvakanyanya hupfumi kushandisa normalizing pane kudzima magokora ane zvakaderera zvinodiwa.
Zvakanaka, zviri pamusoro apa ishumo pfupi kune ruzivo rwakakodzera rwekabhoni simbi elbow kupisa kurapwa, ndinokutendai nekuverenga.
