Kub dov square steel txheej txheem: billet → cua sov → tho → peb yob cross dov, nruam dov los yog extrusion → de rolling → sizing → txias → straightening → hydrostatic test → marking → warehousing.
Cov khoom siv raw rau dov square steel yog square billet.Lub square steel embryo yog txiav los ntawm lub tshuab txiav los ua cov billet nrog qhov ntev li ntawm 1 meter, thiab raug xa mus rau qhov cub kom cua sov los ntawm txoj siv conveyor.Lub billet raug xa mus rau hauv lub qhov cub kom cua sov ntawm qhov kub ntawm txog 1200 ℃.Cov roj yog hydrogen lossis acetylene.Kev tswj qhov kub thiab txias hauv qhov cub yog qhov teeb meem tseem ceeb.
Hauv pob khoom, tsis muaj lwm pob lossis qhwv nrog cov dej tsis muaj dej, lossis raws li cov neeg siv khoom xav tau
Kev thauj mus los:Kev nthuav qhia (Sample Delivery), Cua, Rail, Av, Hiav Txwv shipping (FCL lossis LCL lossis Tej)
