Qhov laj thawj rau inclining steel leeg ntawm lub kaum sab xis thaum hle lawv mus rau hauv chav da dej zinc rau galvanizing

Thaum cov raj hlau tau dipped rau hauv zinc da dej rau galvanizing, lawv yuav tsum tau inclined ntawm lub kaum sab xis txaus, tshwj xeeb tshaj yog thaum galvanizing me me-inch hlab uas sag thiab khoov hauv nruab nrab. Vim li cas qhov no tsim nyog? Ua ntej, peb paub tias cov raj steel, tsis zoo li lwm cov khoom, yog qhov khoob thiab cov tawv nqaij nrog cov tsis muaj zog (tshwj xeeb tshaj yog rau cov kab me me ntawm 10 mus rau 25 millimeters lossis 3/8 "rau 1"). Yog tsis muaj lub kaum sab xis ntawm inclination thiab ceev ceev immersion nyob rau hauv zinc, cov roj nyob rau hauv cov hlab yuav raug tshem tawm. Thaum ob qho kawg ntawm lub raj ntim nrog cov kua zinc, cov roj hauv nruab nrab nthuav dav vim yog cua sov thiab tso cov kua zinc hauv lub raj, ua rau muaj kev phom sij. Tshwj xeeb tshaj yog thaum cov kuab tshuaj nyob rau hauv lub raj tsis tag nrho qhuav, dej evaporates mus rau hauv chav, nce nyob rau hauv ntim los ntawm ntau pua lub sij hawm, ua rau muaj zog ejection ntawm zinc kua los ntawm sab hauv lub raj. Qhov no yog qhov txaus ntshai heev thiab tuaj yeem ua rau plating plating thiab speckling nyob rau sab hauv phab ntsa ntawm galvanized steel raj. Qhov thib ob, thaum lub kaum sab xis ntawm inclination me dhau, tshwj xeeb tshaj yog thaum galvanizing me-inch hlab, 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. Yog li ntawd, cov phab ntsa ntawm cov yeeb nkab steel nyob rau hauv kev sib cuag nrog cov zinc kua nto sai sai elongates thiab khoov mus rau hauv ib qho arc zoo vim cua sov. Lub siab ces thawb nws downwards, tab sis qhov tsis kam ntawm zinc kua tiv thaiv nws ntawm kev txav mus ntxiv. Yog li ntawd, ob qho kawg ntawm lub raj txav mus sai, ua rau lub raj xa mus rau ntawm cov kua zinc. Raws li cov zinc-plating turntables txuas ntxiv txo qis nws, lub raj steel nkag mus rau zinc kua raws li qhia hauv daim duab 3-156. Vim tias muaj huab cua nyob hauv nruab nrab ntawm lub raj khoov, nws nthuav dav thaum cua sov thiab ejects tawm, tso cai rau cov kua zinc los sau lub puab qhov ntawm lub raj. Yog hais tias cov kuab tshuaj tsis tau qhuav tag, lub ejection siab yuav ntau dua thiab txaus ntshai, ua rau ntau plating plating. Yog li ntawd, nws yog qhov zoo dua kom muaj lub kaum sab xis loj ntawm inclination thaum dipping steel hlab rau hauv zinc. Qhov tsawg kawg nkaus lub kaum sab xis yuav tsum tiv thaiv lub raj los ntawm dov tom qab tawm los ntawm zinc da dej. Qhov zoo tshaj plaws configuration yog raws li qhia nyob rau hauv daim duab 3-15c, uas tiv thaiv lub steel tube los ntawm loj-chaw sib cuag nrog cov kub zinc kua nyob rau hauv ib sab, yog li zam kom tsis txhob muaj thermal expansion thiab minimizing raj dabtsi yog khoov. Raws li lub raj yog nias rau hauv cov kua zinc nrog lub turntable, yuav tsis muaj dov. Nyob rau tib lub sijhawm, cov pa roj hauv lub raj tuaj yeem khiav tau yooj yim thiab ua raws. Cov kua zinc yog nyob rau tib theem kab rov tav hauv lub raj, tiv thaiv plating plating. Qhov no yog qhov ua tau zoo dua ntawm cov kauj ruam dhau los ntawm cov tshuab turntable galvanizing nrog lub kaum sab xis 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 hlab. Rolling ntawm steel hlab yuav ua rau plating plating, uas yuav tsum tau ua tiag tiag, tshwj xeeb tshaj yog thaum galvanizing nyob rau hauv aluminium-muaj zinc kua.
