Ama-Rolling Mills Okunciphisa Angakuletha Kanjani Ukubekezelelana Okuqinile Ngaphandle Kokubulala Umsebenzi?

I-athikhili Abstract

Lapho amakhasimende ethengaUkunciphisa Rolling Mills, abavamile ukujaha “umshini” ku-abstract. Bazama ukumisa amakhanda okukhiqiza angempela: ububanzi obungaguquki, i-ovality eyenqaba ukuziphatha, ukuphela kwendawo okubangela izinhlansi. ukusebenza kabusha komfula, kanye nama-changeovers adla i-shift ephila. Lo mhlahlandlela uchaza lokho okwenziwa umshini wokunciphisa umshini, lapho okwenzayo ifanelana nomdwebo noma ukufoja, futhi—okubaluleke kakhulu—ukulinganisa umugqa ukuze uxazulule amaphuzu obuhlungu bekhwalithi nokukhiqiza ngesikhathi esisodwa. Uzothola nohlu lokuhlola olusebenzayo lokukhetha, ithebula lokuqhathanisa, kanye nemibuzo evame ukubuzwa ukukusiza wenze izinqumo ngezinto ezimbalwa ezingalindelekile.

Okuqukethwe

Hlanganyela Ngokubheka

• Thola amaphuzu obuhlungu:i-tolerance drift, ovality, finish, scrap, kanye namabhodlela.
• Qonda indlela:i-multi-pass rolling kunciphisa i-OD futhi ithuthukise i-geometry ngokuguqulwa okulawulwayo.
• Linganisa idizayini yesistimu:ukuqondisa, ukuzinza kwe-roll-gap, ukupholisa, nokulinganisa kubaluleke “njengamandla amahhashi.”
• Khetha ngokuzethemba:sebenzisa uhlu lokuhlola ukuze uqondanise ingxube yomkhiqizo, ukuziphatha okubonakalayo, nezinhlelo zokukhula.
