Some Notices In Casting Crusher Parts
Casting the final shape is mainly through the liquid metal cooling and solidification, in the casting production process, if you do not have a good casting process, casting quality will lead to the problem, affecting the performance of castings and casting service life. Therefore, in the casting manufacturing process need to pay attention to two aspects of control.
Casting Dimensional Accuracy And Surface Roughness Control
In the field of modern manufacturing, the precision and quality of the castings are getting higher and higher. The near-net shape casting technology changes the traditional idea that the casting can only provide the blank. The purpose is to reduce the material consumption, energy consumption and labor consumption. Both inside and outside the quality, for the market and high efficiency. However, casting dimensional accuracy and surface roughness due to many factors and constraints, control is very difficult. Casting is liquid forming, to achieve near-net-shape has a unique advantage in the structure of the casting cavity and shape of the casting method once formed to close to the final shape of the parts, so that processing and assembly processes to a minimum; Dimensional precision and surface quality, so that the casting can be close to the final requirements of the product, so that the balance of dollars or small margin; the other hand, retained the original casting surface is conducive to maintaining the casting corrosion resistance and fatigue resistance superior performance, Thereby improving product life.
Crystallization And Solidification Of The Formation And Control
The structure of liquid metal, the formation and growth of crystal nuclei, the size, orientation and morphology of crystal grains are closely related to the solidified structure of castings, which have great influence on the physical properties and mechanical properties of castings. The purpose of controlling the solidified structure of castings is to obtain the desired structure. To control the solidified structure, it is necessary to have a comprehensive understanding of its forming mechanism, forming process and influencing factors. At present, the effective control of the organization has established methods of deterioration, gestation, dynamic products, the order of solidification, rapid solidification.
In the casting crusher parts production, the control of the above two aspects of the problem, you can guarantee the shape of the casting and dimensional accuracy, to a certain extent, can reduce the cost of spending for market interests.
