Dealing with the defect of high waste rate in casting of large box of shearer,the author discusses the new methods to improve the traditional ways and the development in VRH mould_making new techniques which can be more effective in promoting the casting quality by analysis.

针对采煤机大型箱体铸造废品率较高的缺陷，探讨了改进传统工艺方法，开发采用VRH造型新技术的问题。

This paper researches on 4100QB Cylinder-block of the KW moulding line, particularly introduces the forming mechanism of blowholes on 4100QB Cylinder-block. This paper also analyzed the producing reason of blowholes from ...

本论文还从造型砂处理、制芯、熔炼、模具等方面全面分析了侵入性气孔产生的原因，并制定了相关的改进措施，使4100QB机体气孔废品率从1.5％下降到了0.5％左右，从而获得了满意的经济效果。

Impeller is the core part of slurry pump, in this thesis, the filling and solidfication process of a real hyperchrome white iron impeller were simulated by foundry CAE. It was found that there are some defects by traditional design approach.

叶轮是水泵的核心零件，本论文选取一渣浆泵叶轮，材质为高铬铸铁，该叶轮由于存在铸造缺陷，废品率较高，使用寿命短，使用过程中曾发生严重事故，造成了非常大的负面影响，严重影响了正常的生产秩序。

Small text and line color that you want to avoid in order not to never show the overprint or wrong colors, largening overprinter difficulties, an increase in the rate of waste products.

洪不小笔不朱和线条给制止套色叠印，以免露底或错色，增不小套印艰难，补充废品率。

Compared with ordinary paint, the process would take at this early stage of the construction process to correct mistakes, powder coating the reject rate is extremely low.

这与普通的油漆相比，此工艺可在施工早期纠正施工过程中的缺陷，因此，粉末涂料涂装的废品率是极低的。

In 2005 a factory producing the valve casting more than 2000 t, an integrated waste nearly 170t, reject rate more than 8%.

某厂2005年生产阀门铸件2000多t，综合废品近170t，废品率8％以上。

But because the Motorized Valve Actuators producer prices of raw materials, so that a substantial increase in the cost of production; production efficiency is relatively low compared to other castings, and a high rejection rate and other factors have seriously affected the output of the valve casting.

但由于生产原料涨价，使生产成本大幅提高；生产效率相对其他铸件来说较低及废品率较高等因素，严重影响了阀门铸件的产出。

With the continuous development of the high compacted molding methods and technique, the quality of casting especially their surface quality and size accuracy have been increased significantly, and the rate of waste product was reduced greatly. The degree of ramming of sand mold was improved highly, but the sizes of cavity were changed by the springback of sand mold at the same time, and then it causes the variety of the sizes of casting.

随着高紧实度造型技术和方法的不断发展，铸件的质量尤其是表面质量和尺寸有了很大的提高，大大降低了废品率，但是在砂型紧实度提高的同时，由此产生的型砂回弹改变了行腔尺寸，引起铸件尺寸的变化，成了制约铸件精度和质量的重要因素。

The new circumstances that the discrete manufacturing enterprise is confronted with are analyzed; the function and configuration of production system is expounded; the research actuality and contents about production system capacity in the discrete manufacturing enterprise are summarized; the main research contents in this paper are developed.2. The calculating and analytical methods about production system capacity are studied systemically, a model to calculate rough-cut capacity instantly in "excel" table style is designed, the means to analyze production capacity in different production mode are brought forth, and the balance tactics of production capacity versus load are put forward.3. The application characteristics used in production system about the methods of Computer simulation and CRP in the MRPII/ERP are analyzed and compared; the advantages of Computer simulation method are pointed out; and the simulation researches aiming at production system capacity are implemented by Ithink simulation software.4. A simulation model is founded under the analysis of production system capacity in the production system background of a firm; the change instances of yield, output rate and WIP in the production system are simulated by the action of procurement cycle, machining time, setup time and so on. 5. The change instances of production capacity in the assembly stage are simulated , and rational employees are obtained.
