Cov ntsiab lus tseem ceeb ntawm kev kho cua sov ntawm aluminium extrusion tuag

1. Qhov zoo ntawm kev kho cua sov ntawm aluminium extrusion tuag ncaj qha cuam tshuam rau kev pab cuam lub neej ntawm extrusion tuag. Cov tuag yog quenched thiab tempered "ntxiv" ntau zaus kom tau raws li qhov yuav tsum tau hardness.

   quenching yog los txhim kho lub hardness ntawm pwm, thiab ntau tempering yog los txhim kho lub toughness ntawm pwm thiab stabilize lub internal qauv. Tus nqi hardness ntawm txhua lub ntsiab lus pom ntawm tib lub dav hlau ntawm cov pwm pwm yuav tsum nyob rau hauv qhov kev teev tseg kom pom tau tias tsim nyog.

   
   

2. Kev saib xyuas tshwj xeeb yuav tsum tau them rau cov ntsiab lus hauv qab no thaum kho cua sov ntawm extrusion tuag:

ib. Cov cua kub nyob rau hauv qhov kub thiab txias yuav tsum ceev ceev, thiab lub sij hawm tuav yuav tsum tsis txhob ntev dhau los tiv thaiv extrusion tuag los ntawm overburned los yog overheated, lub overheated nplej yog ntxhib, thiab lub over burned lowmelting point ntsiab thiab inclusions yuav yaj;

b. Aluminium extrusion tuag yuav tsum tau tempered nyob rau hauv lub sij hawm tom qab quenching los tiv thaiv kab nrib pleb;

c. Thaum lub hardness ntawm extrusion tuag pom tias tsis txaus los yog tsis sib npaug tom qab kev kho cua sov, annealing yuav tsum tau nqa tawm, thiab kev kho cua sov yuav tsum tau nqa tawm dua raws li tus txheej txheem .thaum tus nqi hardness tsawg dua HRC35, nws yuav tsis yuav tsum tau annealed, thiab kev kho cua sov yuav tsum tau nqa tawm ncaj qha;

d. Cov txheej txheem kev ntxhov siab tempering yuav tsum tau ntxiv rau qhov loj aluminium extrusion tuag los yog cov pwm tiav nrog cov kab noj hniav nyuaj . tshem tawm cov tshuab hluav taws xob thiab machining kev ntxhov siab, uas yog, tshem tawm cov thermal stress thiab cov ntaub so ntswg stress;

e. Qhov kub ntawm cov pwm quenching roj yuav tsum yog 100 degree kom paub meej cov nyhuv quenching
