Indlela yokwahlula umqulu oshushu kunye obandayo?

I-Hot rolling kunye ne-cold rolling ziinkqubo ezimbini ezibalulekileyo ekusebenzeni kwentsimbi. Basebenzisa amaqondo okushisa ahlukeneyo ngexesha lenkqubo yokuvelisa, okubangela ukungafani kwezinto ezibonakalayo kunye nokubonakala kwemveliso yokugqibela. Oku kulandelayo yintshayelelo eneenkcukacha zezi nkqubo zimbini kunye nomahluko wazo.

Okokuqala, inkqubo eshushu yokuqengqeleka iqhutywa kumaqondo obushushu aphezulu. I-billet yensimbi ifudunyezwa ngaphezu kweqondo lobushushu le-recrystallization ukuya malunga ne-1100 degrees Celsius, kwaye emva koko ixinzelelwe amaxesha amaninzi ngokusebenzisa i-rolling Mill. Ngenxa yeplastiki elungileyo kunye ne-ductility yentsimbi kumaqondo obushushu aphezulu, ukuqengqeleka okushushu kunokutshintsha kakhulu imilo kunye nobukhulu bentsimbi, kwaye inokusebenza okuphezulu kwemveliso. Intsimbi eshushu ephothiweyo idla ngokuba nomphezulu orhabaxa kunye nokunyamezelwa kobukhulu obukhulu, kodwa ngenxa yobukho benkqubo yokuhlaziya kwakhona, ubume bayo obuziinkozo bangaphakathi bulungile kwaye iimpawu zayo zoomatshini ziyafana.

Inkqubo ebandayo yokuqengqeleka iqhutyelwa kwiqondo lokushisa. Intsimbi eshushu eqengqelekayo iyacolwa ukuze isuse isikali se-oxide, ize icinezelwe amaxesha amaninzi kwiqondo lobushushu begumbi kusetyenziswa ilitye lokusila elibandayo. Inkqubo yokuqengqeleka ebandayo inokuphucula ngakumbi ukuguda komphezulu kunye nokuchaneka komgangatho wentsimbi, kwaye iyenze ibe namandla aphezulu kunye nokuqina. Intsimbi epholileyo eqengqelekayo ihlala inomphezulu ogudileyo, ukunyamezelana okuncinci, kunye neempawu ezigqwesileyo zoomatshini, kodwa ngenxa yokuqina komsebenzi, iplastiki kunye nokuqina kwayo kunokuncitshiswa.

Kwizicelo ezisebenzayo, insimbi eshushu kunye ne-cold-rolled-rolled inenzuzo kunye nokungona kwayo, kwaye ukukhethwa kweenkqubo ezifanelekileyo kuxhomekeke kwiimfuno ezithile. Intsimbi eshushu ephothiweyo isetyenziswa ngokubanzi kwimimandla efana nezakhiwo zokwakha, ukuveliswa koomatshini, kunye nokwakhiwa kweenqanawa ngenxa yeendleko eziphantsi kunye nokuqhubekeka kakuhle. Intsimbi eqengqelekayo ebandayo, ngenxa yomgangatho wayo ogqwesileyo womphezulu kunye namandla ayo aphezulu, iqhele ukusetyenziswa xa kusenziwa iinxalenye ezichanekileyo, iipaneli zemoto, kunye neecasings zesixhobo sasekhaya.

Umahluko phakathi kwentsimbi eshushu kunye nebandayo inokushwankathelwa kule miba ilandelayo:

1. Inkqubo yokuvelisa: I-Hot rolling iqhutyelwa kumaqondo aphezulu aphezulu, kwaye ukugqithisa okubandayo kuqhutyelwa kwiqondo lokushisa.
2. Umgangatho womphezulu: Umphezulu wentsimbi eshushu eqengqelekayo rhabaxa, ngelixa umphezulu wentsimbi eqengqelekayo ugudileyo.
3. Ukuchaneka komgangatho: Intsimbi eshushu eqengqelekayo inonyamezelo olukhulu, ngelixa intsimbi eqengqelekayo inokunyamezelana okuncinci.
4. Iipropati zoomatshini: Intsimbi eshushu eqengqelekayo ineplastiki elungileyo kunye nokuqina, ngelixa intsimbi eqengqelekayo inamandla aphezulu kunye nokuqina.
5. Indawo yesicelo: Insimbi eshushu eshushu isetyenziselwa ukwakhiwa kunye nokuveliswa komatshini, ngelixa insimbi epholileyo isetyenziselwa ukuchaneka okuphezulu kunye neemfuno eziphezulu.

Ngolu hlalutyo lungentla, sinokuqonda ngokucacileyo umahluko kunye neenzuzo ezifanelekileyo phakathi kwentsimbi eshushu kunye nebandayo. Xa ukhetha insimbi, kubalulekile ukukhetha uhlobo olufanelekileyo lwentsimbi esekelwe kwiimfuno ezithile zesicelo kunye neempawu zenkqubo, ukuze kufezekiswe umphumo wokusetyenziswa kakuhle.
