Brass busbars yog tus cwj pwm los ntawm lub zog siab thiab zoo plasticity, ua rau lawv haum rau ob qho tib si txias thiab kub ua haujlwm. Lawv kuj muaj zoo weldability thiab corrosion kuj. Qhov kub ua hauj lwm kub rau H90 siab- cov khoom siv tooj dag yog 850-950℃; annealing kub yog 650-720 degree; thiab qhov qis -kub annealing kub rau kev ntxhov siab yog 200℃.
Piv txwv li, ib txoj kev tsim khoom tshwj xeeb rau - zoo li tooj dag busbars siv hauv kev sib txuas lus yog raws li hauv qab no: siv qhov sib piv ntawm 65% electrolytic tooj liab thiab 35% zinc, cov txheej txheem cuam tshuam nrog qis-frequency furnace smelting (smelting kub 1100-} 1160℃(5), ib nrab-casting nruam 2. rpm, kev vibration zaus 400 rpm, amplitude 3-4 mm), sawing, cua sov nyob rau hauv ib lub qhov cub cua sov (ingot cua sov kub 760-780 degree), extrusion (extrusion ceev 0.5-1 m / s, peeling thickness 1-1.5 hli), txiav, thawj rolling drawings thiab vacuum milling kub 580-600 degree, tuav rau 3 teev, txias hauv lub cub tawg, nqus tsev kawm ntawv qib 10 Pa), qhov thib ob dov zeb dov, kos duab, straightening (xyuas flatness ∠0.2, sab dabtsi yog khoov ∠1 mm / m), sawing, tshuaj xyuas (nto tsis muaj khawb, pits, oxidized thiab honing). lub tsev khaws khoom.
