Disgregatio et defectus in centrifuga casting
Centrifugal casting bimetal compositum pipe defectus et imperium usura centrifuga casting, potest obtinere multo magis quam gravitas mittens frumenti structuram, potest animadverto duplex auro, ad metallurgicum, ut intellegi potest, ut non efficaciter ad alium, lateque, ita ne composite Pipe sub conditione alterna æstus accentus stratification . et schematic diagram de centrifuga mittens, ostensum est in Figura {I}}

The cracks extend from the base level along the base level to the end of the transition area between the base and lining layer, while there is no crack in the lining layer.

The uneven tube billet thickness and the crack defect of the tube billet base are caused by the rotation speed, while other factors have little influence. Usus formula centrifuga casting:

Another reason may be to choose the pouring temperature is not reasonable, if the molten metal liquid into the casting temperature is too high, Viscositas reducitur, quia auro liquore usura excelsum satis celeritate vincere effectum gravitatis erit valde difficile, potest, in mitigatione, ut in hac causa pluvia, ut in hoc casu, ut sit difficile est in hoc casu, ut sit difficile in hoc casu, quod est in hoc tempore, ut sit difficile in hoc casu, quod est in hoc tempore, ut sit difficile in hoc casu, ut sit difficile est in hoc quod est in hoc tempore, ut in hoc est, ut in hoc est, ut sit difficile in hoc casu, quod est in hoc tempore, quod est in hoc tempore, ut est in hoc tempore, ut sit difficile in hoc casu, quod est difficile in casu, quod est in hoc tempore, ut est in hoc tempore, ut in hoc est, ut in hoc est, ut sit difficile in casu, ut in hoc est, ut a gyrationis celeritas in hoc casus {{{XXIII}} Hoc phaenomenon potest crescere gyrationis celeritas mittentes, ita augendae frictio inter metallum liquidum et proiectio.

Cold separation is also called lap, is caused by the use of inappropriate pouring process, such as unstable pouring, injection speed, so the pouring speed should fully ensure that the metal liquid continuously into the whole casting surface and then reach the end of the casting. If the pouring speed is too slow, it will produce the phenomenon of flow off, the Phaenomenon de frigore separationem et apparebit.

2.5 Needle orifice stoma (stoma, eye) in centrifugal casting, stomatal defects are also relatively common, when the liquid metal liquid contains a large amount of gas, there is moisture in the body or cast, or the paint selection is not appropriate, needle orifice or eye defects will occur. In the casting, because the metal casting has no pores for the gas to escape, and the centrifugal casting of the metal liquid Est ipsum ieiunium, ita et pinhole produci in tenuis-muratam} {{IV}} stoma stoma defectus potest vitari a sequentibus, utere ferro projicere ferrum, typus; Preheating ante casting; Nolite uti coating materiae continet crystallina aquam; Non utor nimis altus effundere temperatus {{V}} cum usura pingunt, si ad Bentonite non permanere cum aqua, et crystallina aquae, et in arida erit facilis ad fructum et in muro et in muro flatem et muro et muro be excluded, which is conducive to the elimination of stomatal defects. In bronze and iron castings, pinhole-like pores appear outside the cast like clear and bright spots, like hemp pits inside the cast, and the diameter of the pores is very small. In the metal liquid melting, will also cause the dissolution of gas, dissolved gas has hydrogen, oxygen and nitrogen, etc., Per preheating et siccatio rudis materiae, potest efficaciter reducere Gas infiltration, potest etiam uti ferventis liquescens modum ad removendum Gas.

For sand casting, the cooling speed from the outer surface is very low, cooling both from the inner surface and from the outer surface, so the shrinkage occurs in the surface of the solidification front, to avoid these defects, the inner surface temperature should be kept high enough to control the directional solidification, if the internal drying is not evenly, molten metal liquid may erode some impurities Per infundens, producendum slag.
