Automobile Castings The Continuous Development Of The Process

Over the past decade, Automobile Castings in the proportion of the casting is growing, 2011 growth is expected to remain at 10 to 15%. The booming Chinese auto industry has brought more hope to China's entire foundry industry, especially the automotive casting industry. Automobile castings are more complex than traditional industries, with high quality requirements and large batch quantities. Therefore, it is necessary to adopt cast equipment and facilities with high level of production efficiency and high capital investment. With the continuous development of the automotive industry, as well as energy saving, environmental protection requirements, the quality of automotive castings also put forward higher and higher requirements.

Slagging defects are a very important type of casting casting defects, accounting for more than half of the total amount of defects. The criteria for the control of slag defects are mainly based on the performance of the castings, the more precise, the more stringent the working conditions are. How to reduce the proportion of slag has become an important problem in the production of automobile castings. With the continuous development of casting process, filtration technology has become an indispensable means to reduce the slagging of automobile castings.

In the 1950s, there was a report on the use of filters in China, but because of the overall casting level, the quality of the filter, the cost and other factors, the amount is relatively small. With the rapid development of China's automobile production enterprises, the output of automobile castings increased year by year, the quality of castings towards the high quality, high efficiency, high performance, fine and other direction, the filter technology is also increasingly attention. From the initial simple use of lumps to the use of simple and coarse prototype porous filter, and then slowly transition to the filter effect of better fiber filter, and then to the two-dimensional pore structure of the straight hole ceramic filter, and ultimately to the present Three-dimensional structure of the ceramic foam filter, with its high precision filtration, high porosity and other advantages in the automotive casting filter technology occupies a pivotal position. At present, there are three kinds of filter used in casting production:

① glass fiber filter: made of high temperature glass fiber and resin, can be larger than the mesh of the filter out, the effect of general, cheap, simple production process.

② straight hole ceramic filter: the ceramic material to suppress or extrusion molding, filtration effect between the fiber filter and foam ceramic filter between.

③ foam ceramic filter: came out in 1978, was used for non-ferrous alloys, in 1985 began for cast iron, cast steel, the production process to organic precursors for the skeleton, coated with high temperature material slurry, the high temperature firing Into, have a good filter effect. Moderate strength, the best filter. At present in the casting industry, especially in automotive casting applications are increasingly widespread.
