介绍了自行研制的大型分体式反重力铸造设备,该设备有效地解决了生产超大、超重大型复杂薄壁铸件时存在的问题,其控制系统具有较高的控制精度和可靠性。
Meanwhile,complicated and thin-wall castings in which the thinnest wall is under 1mm are produced.
采用Delphi语言开发了VCPC-1真空差压铸造智能控制的可视化界面,界面以视窗形式弹出,实现了下位机的近程控制和上位机的远程控制;并生产了最小壁厚1mm以下的复杂薄壁铸件。
The study indicated effect extent of four main technology parameter on filling ability of thin-walled castings was rising pressure time, crystal pressure, degree of vacuum, filling pressure in turn.
研究结果表明,这些参数对薄壁铸件充型能力影响程度的大小依次为升压时间、结晶压力、真空度、充型压力。
Through technological design and strict process discipline,the 1mm thin-walled castings were produced by investment casting successfully.
通过工艺设计和严格工艺纪律,实现了1mm厚薄壁铸件的熔模铸造生产,既提高了企业的效益,也为熔模铸造生产薄壁铸件提供了工艺参考。
In this paper, the basic conocept and characteristics of thin-walled castings are introduced.
介绍了薄壁铸件的概念和基本特征。
One of main reasons to result in casting hot tears is poor yieldability of the mold(core),particularly when thin wall steel castings are produced by a no bake resin sand,the problem is more serious.
热裂产生的主要原因之一就是型 (芯 )砂容让性差 ,尤其是用自硬树脂砂生产薄壁铸钢件时 ,这个问题显得特别突出。
On the basis of physical and chemical process of interface of Titanium/Zirconia ceramics, mechanics of curdle of Zirconia collosol and desiccation of silica sol binder, Zirconia-containing surface coating materials were optimized through experiment, Zirconia shell manufacturing process was developed to produce high quality thin-wall Titanium castings.
型壳中的锆、氧等元素的热扩散而产生了钛铸件的表面污染层,其厚度一般为20-200μm;采用ZrO_2、ZrO_2(CaO)、和ZrO_2(Y_2O_3)面层材料,铸件的反应层厚度依次为2001μm、100μm、50μm,由于氧化钇的加入,降低了氧化锆分解速度及Zr的活性,相应其面层材料稳定性最好,铸件污染层最薄,只有50μm,适合我公司生产薄壁钛铸件面层材料。
