Rolled steel daim hlau yog rhuab mus rau qhov kub thiab txias rau ib lub sij hawm, ces txias hauv huab cua. Cov txheej txheem no refines lub grain qauv, txhim kho toughness thiab ductility, thiab xyuas kom meej weldability zoo rau tom ntej fabrication.

Txheej txheem kho saum npoo:

Kev txhaj tshuaj blasting lossis cov txheej txheem pickling yog siv los kho cov hlau phaj nto. Cov txheej txheem no zoo tshem tawm oxide nplai, xeb, thiab burrs tsim thaum lub sij hawm dov thiab kho cua sov, ua kom lub ntsej muag huv si thiab du uas pab tswj vuam thiab tiv thaiv qhov tsis xws ntawm cov khoom tiav.

Tsis yog -Txoj kev kuaj kev puas tsuaj:

Ntau yam uas tsis yog{0}} cov txheej txheem kuaj kev puas tsuaj raug coj los tshuaj xyuas cov hlau phaj. Kev kuaj ultrasonic feem ntau yog siv los kuaj xyuas qhov tsis xws luag, thaum kuaj pom thiab kuaj pom qhov tsis pom tseeb kom tsis muaj qhov tsis xws luag. Cov txheej txheem no lav cov qauv kev ncaj ncees ntawm cov hlau tsis muaj kev puas tsuaj rau cov khoom.

Precision txiav thiab tsim cov txheej txheem:

Rau fabrication rau hauv lub siab lub nkoj Cheebtsam, precision txiav txheej txheem xws li nplaim taws txiav los yog plasma txiav yog saws kom tau txais qhov ntau thiab tsawg. Bending, stamping, thiab dov cov txheej txheem kuj tau txais los ua cov hlau phaj rau hauv lub plhaub, lub taub hau, thiab lwm yam uas yuav tsum tau ua, xyuas kom lawv ua tau raws li kev sib dhos thiab kev pabcuam.
