Vim li cas cov yeeb nkab steel yuav tsum inclined ntawm lub kaum sab xis thaum nkag mus rau zinc da dej rau dipping thiab galvanizing?

Thaum cov yeeb nkab steel nkag mus rau hauv zinc da dej rau dipping thiab galvanizing, nws yuav tsum tau inclined ntawm lub kaum sab xis txaus, tshwj xeeb tshaj yog thaum galvanizing me-inch steel kav, uas sag thiab khoov heev nyob rau hauv nruab nrab, yuav tsum tau ib tug loj inclination lub kaum sab xis. Qhov no yog vim li cas? Ua ntej, peb paub tias cov yeeb nkab steel, tsis zoo li lwm yam khoom, yog hollow thiab elongated nrog tsis zoo rigidity (tshwj xeeb tshaj yog rau me me diameters li ntawm 10 mus rau 25 millimeters, los yog 3/8 "mus rau 1"). Yog tias tsis muaj lub kaum sab xis thiab cov zinc dipping sai, cov roj hauv cov yeeb nkab steel tsis tuaj yeem raug tshem tawm. Yog li ntawd, tom qab ob qhov kawg tau ntim nrog cov kua zinc, cov roj hauv nruab nrab nthuav dav vim yog cua sov thiab ejects cov zinc kua hauv cov yeeb nkab steel, ua rau muaj kev puas tsuaj. Tshwj xeeb tshaj yog thaum cov kuab tshuaj nyob rau hauv cov yeeb nkab steel tsis qhuav tag, dej evaporates mus rau hauv chav, nce nyob rau hauv ntim los ntawm ntau pua lub sij hawm, uas ua rau ib tug muaj zog ejection ntawm zinc kua los ntawm lub steel yeeb nkab. Qhov no yog qhov txaus ntshai heev thiab tuaj yeem ua rau tsis muaj galvanizing thiab cov pob zeb nyob rau sab hauv phab ntsa ntawm cov yeeb nkab steel galvanized. Qhov thib ob, thaum lub kaum sab xis me dhau, tshwj xeeb tshaj yog thaum galvanizing me-inch steel kav, qhov nruab nrab sagging tuaj yeem nkag mus rau hauv kev sib cuag nrog zinc kua nto yuav luag ib txhij nrog lub taub hau kawg. Nyob rau hauv cov ntaub ntawv no, cov phab ntsa ntawm cov yeeb nkab steel nyob rau hauv kev sib cuag nrog zinc kua nto sai sai elongates thiab khoov rau hauv ib tug arc vim tshav kub. Raws li lub siab thawb nws downwards, qhov tsis kam ntawm zinc kua tiv thaiv nws los ntawm kev nkag mus rau hauv cov kua zinc hauv qab no, ua rau ob qhov xaus sai sai thiab cov yeeb nkab steel dov ntawm zinc kua nto. Thaum lub galvanizing turntable tseem txo qis nws, cov yeeb nkab steel nkag mus rau zinc kua raws li qhia hauv daim duab 3-156. Vim tias muaj huab cua nyob hauv nruab nrab ntawm cov yeeb nkab steel, nws nthuav thiab ejects thaum cua sov, tso cai rau cov kua zinc los sau lub puab qhov ntawm cov yeeb nkab steel. Yog hais tias cov kuab tshuaj tsis qhuav, qhov ejection siab yuav ntau dua thiab txaus ntshai, ua rau muaj kev ploj tuag ntau dua. Yog li ntawd, nws yog qhov zoo dua kom muaj lub kaum sab xis loj dua thaum dipping cov yeeb nkab steel rau hauv zinc. Qhov tsawg kawg nkaus lub kaum sab xis yuav tsum tiv thaiv cov yeeb nkab steel los ntawm dov tom qab tawm hauv cov zinc da dej. Qhov zoo tshaj plaws configuration, raws li qhia nyob rau hauv daim duab 3-15c, tiv thaiv cov yeeb nkab steel los rau hauv loj-thaj chaw sib cuag nrog kub zinc kua nyob rau hauv ib sab, tsis txhob loj thermal expansion thiab txo steel yeeb nkab dabtsi yog khoov. Raws li cov yeeb nkab steel yog nias rau hauv cov kua zinc nrog lub turntable, yuav tsis muaj dov. Nyob rau tib lub sijhawm, cov pa roj hauv cov yeeb nkab steel tuaj yeem yooj yim khiav tawm ntawm cov yeeb nkab nyob rau hauv ib ntus. Cov kua zinc yog nyob rau tib theem kab rov tav hauv cov yeeb nkab steel, tiv thaiv tsis tau galvanizing. Qhov no tuaj yeem ua tiav zoo dua ntawm cov kauj ruam dhau ntawm turntable galvanizing tshuab nrog lub kaum ntse ntse zinc loj. Txawm li cas los xij, ntawm cov tshuab galvanizing tsis tu ncua, dov tau hais ntau dua, tshwj xeeb tshaj yog thaum galvanizing me-inch steel kav. Rolling ntawm cov yeeb nkab steel tuaj yeem ua rau tsis muaj galvanizing, uas yuav tsum tau ua tiag tiag, tshwj xeeb tshaj yog thaum galvanizing hauv zinc kua uas muaj txhuas.
