Valve castings yog tsim los ua qhov tsis xws luag

1. Lub stomata

Qhov no yog cov kab noj me me uas tsim los ntawm cov roj uas cov txheej txheem hlau solidification tsis khiav hauv cov hlau. Nws cov phab ntsa sab hauv yog du thiab muaj roj, uas muaj kev cuam tshuam siab rau ultrasonic nthwv dej, tab sis vim tias nws yog qhov yooj yim kheej kheej lossis ellipsoid, nws yog qhov tsis xws luag, uas cuam tshuam rau nws qhov kev xav ntawm amplitude. Cov huab cua qhov nyob rau hauv lub ingot yog flattened rau hauv ib cheeb tsam tsis xws luag tom qab forging los yog dov, uas yog ib qho txiaj ntsig kom pom los ntawm kev tshawb pom ultrasonic.

2. Clip slag

Lub slag nyob rau hauv cov txheej txheem smelting los yog lub refractory ntawm lub cub tawg lub cev peels rau hauv cov kua hlau, thiab yog koom nyob rau hauv lub casting los yog steel ingot thaum pouring, tsim lub slag clamp defect. Slag feem ntau tsis muaj nyob ib leeg, feem ntau nyob rau hauv ib lub xeev tuab los yog tawg ntawm qhov sib txawv qhov tob, nws zoo ib yam li ntim tsis xws luag tab sis feem ntau muaj qee yam linearity.

3. Casting tawg

Cov kab nrib pleb nyob rau hauv lub casting yog tsuas yog tshwm sim los ntawm lub shrinkage kev nyuaj siab ntawm cov hlau txias solidification tshaj qhov kawg lub zog ntawm cov khoom, nws muaj feem xyuam rau cov duab ntawm lub casting tsim thiab casting txheej txheem, thiab kuj muaj feem xyuam rau lub cracking rhiab heev ntawm ib co impurities nyob rau hauv cov khoom. cov ntaub ntawv hlau (xws li cov ntsiab lus sulfur siab, txias brittleness, siab phosphorus cov ntsiab lus, thiab lwm yam). Nyob rau hauv lub spindle, kuj yuav muaj kab nrib pleb nyob rau hauv lub ncej siv lead ua, thiab nyob rau hauv lub tom ntej no billet forging, nws yuav nyob twj ywm nyob rau hauv lub forging raws li lub internal tawg ntawm forging.

 

4. Tig daim tawv nqaij

Qhov no yog steelmaking los ntawm lub ladle mus rau lub ingot casting ingot, vim hais tias ntawm pouring cuam tshuam, ncua, poured rau hauv cov kua hlau nto nyob rau hauv cov huab cua ceev ceev txias daim ntawv oxide zaj duab xis, tshiab pouring rau hauv cov kua hlau yuav tawg mus rau hauv lub ingot lub cev thiab tsim ib tug hierarchical. (cheeb tsam) defects, nws nyob rau hauv lub tom ntej ingot billet forging yog tsis forging.

5. Anisotropy

Thaum lub casting los yog ingot txias thiab solidified, qhov txias ceev los ntawm qhov chaw mus rau qhov chaw yog txawv, yog li sib txawv crystallization ntaub so ntswg yuav tsim, uas qhia tau hais tias lub anisotropy ntawm txhua yam khoom, thiab kuj ua rau lub anisotropy ntawm acoustic zog, uas yog. , muaj lub suab sib txawv thiab suab attenuation ntawm qhov chaw mus rau saum npoo. Lub xub ntiag ntawm no anisotropy tuaj yeem muaj qhov cuam tshuam tsis zoo rau qhov loj thiab txoj hauj lwm ntawm qhov kev soj ntsuam tsis xws luag thaum kuaj ultrasonic.
