The core manufacturing method and core drying method for producing gray iron casting with deep holes was introduced, and the points should be paid attentions during cores setting were described. 介绍了铸造深孔灰铁铸件时泥芯的制作方法和烘烤方法,并指出了合箱下泥芯需要注意的事项。
Analysis is made on gas evolution changing pattern of furane bonded sand core material after vacuum hardening, on affection to compressive strength arid the microstructure after infrared drying. 分析研究真空硬化后的呋喃树脂砂芯材料发气性变化规律、红外烘干后对抗压强度的影响及其微观结构特点。
The Design and Reform of a Core-drying Furnace 燃煤型芯烘干炉的设计与改造
Compared with the existing process, it is characterized by smooth core extracting, high accuracy, even core wall and light in weight, with less porosity and low waste core, but without binding and drying. 与原工艺相比,有抽芯顺畅,坭芯无需粘合,无需烘干,尺寸精度高,气孔缺陷少,废芯率低的特点,且坭芯壁厚均匀,重量减轻。
The results shows that the release of core material is caused by breakup of W/ O in process of rapid dispersion in drying liquid and W/ O/ W during the drying process. 结果表明芯材损失是由W/O乳状液在干燥浴中快速分散时破裂和干燥过程中的破裂所引起的。
The lime white spray nozzle is the core part of drying haze desulphurization installment, which has the significant influence to the haze desulphurization. 石灰浆雾化喷嘴是喷雾干燥烟气脱硫装置的核心部件,对烟气脱硫有着重要的影响。
We studied the technological process conditions, such as emulsifying conditions, fixing conditions, wall-material concentration, wall-material ratio, the ratio of core to wall, drying temperature, and determined the optimum process parameters. 研究成囊乳化过程、固化过程、壁材浓度、壁材比例、芯壁比、胶囊干燥温度等工艺条件,找出最佳制备超细胶囊方案。
The micro-porous surface not only provided a lot of vaporized core but also improved the wettability of water in the channel surface, which can avoid drying out on smooth surface. 微多孔表面不仅提供了大量汽化核心,而且改善了水在其表面的润湿性,避免了饱和流动沸腾干度较大时,光滑表面出现的蒸干现象。
