Hot-rolled forged forged Steel bar ndi chinthu chachitsulo chomwe chimapangidwa ndi njira yowotchera, yomwe nthawi zambiri imakhala ndi zida zamakina apamwamba komanso magawo ambiri ogwiritsira ntchito. Zotsatirazi ndikuwunika kwatsatanetsatane kwa ndodo zopindika zotentha:

Njira yopukutira yotentha: Kugudubuza kotentha kumapangidwa ndikukonza pang'onopang'ono billet yachitsulo pansi pa kutentha kwakukulu kudzera m'njira zingapo zogudubuza (monga kuponyedwa kosalekeza kosalekeza → kugudubuza movutikira → kugubuduza kwapakatikati → kumaliza kugubuduza, etc.).

Pochita izi, billet yachitsulo imatenthedwa kutentha kwambiri ndipo kenako imakulungidwa kangapo kupyolera mu mphero kuti potsirizira pake apange mawonekedwe a bar ndi kukula kwake. Njira imeneyi akhoza kwambiri kusintha mkati kapangidwe ndi katundu wa zinthu, kupereka bwino mawotchi katundu ndi katundu processing.

Zipangizo zamakina: zomwe zimagwiritsidwa ntchito popanga zida ndi zida zamakina osiyanasiyana, monga ma bearing, magiya, shafts, ndi zina.
Makampani opanga magalimoto: amagwiritsidwa ntchito popanga makina otumizira, makina oyimitsidwa, magawo a injini, ndi zina zambiri zamagalimoto.
Zomangamanga: zomwe zimagwiritsidwa ntchito popanga zitsulo zomangira, monga mizati yachitsulo, zitsulo zachitsulo, zitsulo zachitsulo, etc.
