Cold heading tuag yog stamping tuag mounted ntawm ib tug xovxwm rau xuas nrig ntaus, khoov, ncab, thiab lwm yam.
Lub taub hau txias tuag yog raug rau qhov hnyav hnyav hnyav thiab nws qhov concave tuag nto yog raug rau siab compressive kev nyuaj siab.Cov khoom siv tuag yuav tsum muaj lub zog siab, toughness thiab hnav tsis kam.Tom qab kev kho cua sov, qhov chaw ntawm pebtungsten carbide txias taub hau tuagyuav tsum muaj siab hardness thiab lub plawv yuav tsum muaj zoo toughness, yog li ntawd lub nto muaj ib tug tej yam compressive kev nyuaj siab uas yuav offset qhov kev nyuaj siab borne nyob rau hauv lub txias taub hau txheej txheem.Nws tuaj yeem ua rau tuag ntev dua.
Txhawm rau ua kom muaj kev ua tau zoo ntawm tungsten carbide txias taub hau khoom, tag nrho pebcarbide txias taub hau tuagblanks yog quenched thiab tempered tom qab sintering txheej txheem.Cov txheej txheem quenching thiab tempering yog kom sov cov sintered alloy blanks nyob rau hauv ib tug high pressure gas quenching rauv kom dhau 1300 degrees thiab ces sai thiab sharply txias lawv thiab ces sov lawv dua rau tempering.Nyob rau hauv cov txheej txheem no, thaum kub nce, solubility ntawm tungsten carbide nyob rau hauv cobalt nce, thiab qhov kub thiab txias txias sharply kom cov tungsten carbide yaj nyob rau hauv lub cobalt theem tsis precipitate nyob rau hauv lub sij hawm, thiab ib co los yog tag nrho cov ntawm nws yog khaws cia.Tom qab ntawd tempered kom tshem tawm cov quenching internal hardness.Los ntawm kev tswj cov decomposition thiab dispersion ntawm saturated solid tov, cov metallurgical muaj pes tsawg leeg thiab lub koom haum ntawm cov alloy yog hloov, thiab cov kev ua tau zoo yog txhim khu kev qha.
