Our casting production has won nine years ranked first in the world, I am worthy of the world's national plan of casting a big country. But such a casting producing countries, still has to import from overseas casting products. This is not due to the lack of the total cast, but the amount of high-end casting products no way satisfied the requirements of the domestic production. In fact there are more than the number of low-end casting nobody cares. Low-end casting foundry overcapacity, poor product sales line, affecting the casting company's capital returns, the implementation of re-production, continue to move the company's impact on the progress of the casting. To promote the progress of the casting industry, the excess should be low-end can often be converted into high-capacity bucket wheel guard wharf facilities, paying particular attention to the progress of a certain stage of the domestic shortage of high-end features of the device, to the satisfaction of the market, thus enhancing the casting industry progress. Casting quality has a great impact on the performance of mechanical products. For example, wear resistance and dimensional stability of the casting machine, a direct impact on the accuracy of the machine to maintain life; all kinds of pump impeller, housing and hydraulic cavity size, the accuracy of the profile and the surface roughness of the bucket wheel guard pier prices directly affect the efficiency of the pump and the hydraulic system, the development of energy consumption and cavitation, and so on; the strength of the internal combustion engine block, cylinder head, cylinder, piston rings, exhaust pipes and other castings and resistance to spalling resistance, direct impact the working life of the engine. Casting metal forming theory often called liquid molding casting, casting forming technology has a long history. As early as 5,000 years ago Hom supply dock wheel guard, our ancestors could cast copper and bronze. Casting is the most widely used metal liquid molding processes. It is the liquid metal is poured into the mold cavity, wait until the cooling and solidification, to obtain a certain shape or parts of the method blank.
