1.Material: Feem ntau yog siv high-strength alloy steel los yog carbon steel
2.Steel billet preheating: Thaum tshav kub kub ntawm steel billet mus rau qhov tsim nyog kub kom ntseeg tau zoo plasticity ntawm cov khoom.
3.Mould tsim: Tsim thiab tsim cov pwm forging haum rau tsheb bolts
4.Forging kev ua haujlwm: Muab lub preheated steel billet rau hauv forging pwm thiab siv siab los tsim cov duab uas xav tau.
5.Kev kho cua sov: Tom qab forging, tsheb bolts feem ntau xav tau kev kho cua sov los txhim kho lawv lub zog thiab hardness.Cov kev kho cua sov uas muaj xws li quenching thiab tempering.
6.Surface kho: Yuav kom txhim kho corrosion kuj thiab hnav tsis kam ntawm bolts, kev kho deg feem ntau yog ua tiav.Cov txheej txheem kho saum npoo muaj xws li galvanizing, npib tsib xee plating, phosphating, thiab lwm yam.
