Tirohanga mo te Cold Rolled Steel Coil

Ko te porowhita makariri he mea hanga mai i te porowhita wera wera. I roto i te tukanga matao hurihia, ka hurihia te porowhita wera i raro i te pāmahana recrystallization, a ka hurihia te maitai o te tikanga hurihia i te pāmahana rūma. He iti te pakaru me te kirihou iti o te pepa rino me te ihirangi silicon teitei, me whakamahana ki te 200 °C i mua i te hurihanga makariri. Mai i te mea kaore i te wera te porowhita makariri i te wa o te mahi whakaputa, kaore he hapa penei i te pitting me te waikura rino e kitea ana i roto i te wera wera, a he pai te kounga o te mata me te whakaoti.

Te Whakamahinga o te Coil Steel Cold Rolled

He pai te mahi o te porotaka makariri, ara, na roto i te hurihuri makariri, te takai makariri me te pepa rino me te matotoru angiangi me te tino tika ka taea te whiwhi, me te tika teitei, te teitei o te maene o te mata, te ma me te kanapa o te mata o te pepa makariri. , me te paninga ngawari. Ko te tukatuka whakakikorua, te momo, te whakamahi whanui, me nga ahuatanga o te mahi tohu tohu teitei me te kore-tawhito, te iti o te hua, na reira he maha nga whakamahinga o te pepa matao makariri, te nuinga o te whakamahi i roto i nga motuka, i nga papa rino kua taia, i te hanga, i nga mea hanga, paihikara, me etahi atu. Ko te ahumahi hoki te mea pai rawa atu mo te hanga i nga pepa rino whakakikoruatia.
