Kev Xeem Xeem
Flattening xeem
Cov raj hlau nrog ib txoj kab uas hla sab nraud ntau dua 22 hli thiab txog 400 hli, thiab phab ntsa thickness ntau dua 10 hli yuav tsum tau ua qhov kev ntsuam xyuas flattening. Tom qab cov qauv yog flattened
Khoov xeem
Cov raj hlau uas muaj lub taub sab nraud tsis pub ntau tshaj 22 hli yuav tsum tau txais kev sim khoov. Lub kaum sab xis yog 90o. Lub vojvoog dabtsi yog khoov yog 6 npaug ntawm txoj kab uas hla ntawm lub raj steel.Tom qab khoov cov qauv, tsis muaj fissures lossis kab nrib pleb raug tso cai los tshwm ntawm cov qauv.
Kev ntsuam xyuas macroscopic
Rau cov raj steel ncaj qha los ntawm kev nruam nruam los yog steel ingots, cov neeg muab khoom yuav tsum tau lees tias tsis muaj cov pob dawb, impurities, sub-dog cua npuas, pob txha taub hau thaj ua rau thaj los yog txheej txheej ntawm cov ntoo khaub lig-sectional acid pickled macroscopic cov ntaub so ntswg ntawm billet los yog cev steel.
Kev tshuaj xyuas tsis muaj kev puas tsuaj
Raws li cov neeg xav tau kev thov, uas yog tom qab ntawd sib tham ntawm cov neeg muab khoom thiab xav tau ob tog thiab qhia nyob rau hauv daim ntawv cog lus, ultrasonic flaw detection tej zaum yuav ua ib tug neeg ua rau steel hlab. Lub longitudinal phau ntawv tsis zoo ntawm cov qauv coj mus kuaj yuav tsum ua tau raws li qhov yuav tsum tau ua rau kev soj ntsuam tom qab lees paub qib C8 teev hauv GB / T 5777-1996.
