Cive Castings sunt proni ad producendum defectus

I. De stomata

Hoc parva cavum formatae per Gas quod metallum solidificationem processus non effugere intra metallum. Et intus pariete est lenis et continet Gas, quod habet alta reflectivity ad ultrasonic fluctus, sed quod est basically sphaericam vel ellipsoideam, id est a punctum defectus, quod afficit reflexio amplitudine. Aeris foraminis in inebriat in an area defectum post clangoris vel volvens, quod est utile inveniri per ultrasonic deprehendatur.

II. Clip Slag

Slag in Smelting processus vel refractaria in fornace corpus peels in liquorem metallum, et involved in mittentem aut ferro ingot cum infundendo, formatam inffertum fibula. Slag plerumque non est solum, saepe in densa re publica vel dispersi diversis profundis, est similis volumus defectus sed saepe habet aliquam linealis.

III. Clama casting

The crack in the casting is mainly caused by the shrinkage stress of the metal cooling solidification exceeds the ultimate strength of the material, it is related to the shape of the casting design and casting process, and also related to the cracking sensitivity of some impurities in the metal materials (such as high sulfur content, cold brittleness, high phosphorus content, etc.). In fusum, ibi quoque rimas in hastile crystal et in subsequent Billet cudere, manebit in campum quod internum crack in coelum.

IV. Turn super cute

Hoc est steelmaking a elit in ingot ingot, quia infundens intermissione, pausa, infudit in liquidum metallum superficiem in aere celeri refrigerationem formam et confringet in ingot et formare in hierarchica metallum et confringet in tinea et in tibus in tinea tecta et non clangore.

V. Anisotropy

When the casting or ingot is cooled and solidified, the cooling speed from the surface to the center is different, so different crystallization tissue will be formed, which shows the anisotropy of mechanical properties, and also leads to the anisotropy of acoustic properties, that is, there is different sound velocity and sound attenuation from the center to the surface. In praesentia huius anisotropy potest habere adversa effectus in magnitudine et positus de taxatis defectibus durante ultrasonic deprehendatur.
