The flow of molten metal are the forefront of the lost foam pyrolysis products, it will happen with the liquid metal reflect and affect the quality of metal liquid, if the liquid metal filling process in pyrolysis products should not rule out smoothly, it is easy to cause stomatal , Cockle, by defects such as carbon.

金屬液的流動(dòng)前沿是熱解的消失模產(chǎn)物，它會(huì)與金屬液發(fā)生反映并影響到金屬液質(zhì)量，如果金屬液充型過程中熱解產(chǎn)物不能順利排除，就容易引起氣孔国产黄网站在线观看免费版、皺皮、增碳等缺陷久久精品伊人不卡一区。

Numerical simulation results show that the fluid flow in Lost Foam Process was different from that in an ordinary green sand mold, the molten metal flow forwards in a circular-arc shape from the ingate, meanwhile, the nature of the gating system influenced the filling process notably. As the polystyrene pattern decomposition has a strong quenching effect on the flowing metal fornt, a high temperature gradient was formed at the flowing metal front, this resulted in the dropping of temperature of the metal to the liquidus temperature quickly and decreased the flowability of molten metal, the temperature distribution in the metal behind, however, was even. The properties of the pattern and the coating affected the temperature distribution remarkably.

從內(nèi)澆口開始95免费视频，金屬液呈放射狀均勻向前充填国产春色一级视频免费，同時(shí)澆注系統(tǒng)性質(zhì)顯著影響金屬液充型過程的流場(chǎng)；由于聚苯乙烯模樣氣化吸熱對(duì)金屬液的激冷作用激情小说另类，在金屬液流端部區(qū)域產(chǎn)生很大的溫度梯度中文在线中文字幕，使得端部區(qū)域金屬液很快降至液相線溫度，降低了金屬液的充型能力操美女6666，而后續(xù)金屬液中溫度分布則比較均勻人日人视屏，模樣性能、涂料性能顯著影響這一溫度分布特點(diǎn)毛片免费看不卡网站。

The droplet transfer of twin-wire co-pool gas shielded metal arc welding process takes great effects on the behavior of the molten pool by transferring energy, momentum and fluid flow to the molten pool which will affect the weld appearance.
