Is made more economical methods of rough shape, the shape of complex parts can show its economy. Such as automotive engine blocks and heads boat anchor, ship propellers and exquisite works of art. Somewhat difficult to cut parts, such as gas turbine parts nickel-based alloy can not be formed without casting method. For casting engineers and mechanical design engineers, heat treatment is a very meaningful, but a very high value for ways to improve the material quality, by the heat treatment can alter or affect the organization and the nature of cast iron, and can get higher strength, hardness, and to improve the wear resistance and the like. Since the purpose of the different anchor pattern is very much the type of heat treatment, it can be mainly divided into two basic categories, the first category is the organizational structure will not change and does not change through the heat treatment or should happen, the second is the basic organizational structure those changes. The first heat treatment procedures, mainly used to eliminate stress anchor, and this is due to the different stress conditions and conditions caused by cooling in the casting process. Organization, strength and other mechanical properties, which does not change significantly due to the heat treatment. 3. The composite material further develop solidification technology for preparing a composite material called composite mouth, is in the non-metallic or metallic matrix reinforced with the introduction of special ingredients anchors or maintenance, by controlling the solidification phase by reinforcing the distribution arranged in a desired manner or a material with special properties. Since the matrix composite material having a high fracture resistance, plus enhanced phase of existence, it can exhibit different ordinary single-phase structure material properties such as high strength, high temperature performance and good fatigue resistance, it has developed a multi- seed preparation process for composite materials, such as the combination solidification situ composites were prepared. Prospects in this field will become increasingly widespread. Production of anchors, anchor, Chen Hua Chen machinery provided by the China Machinery Equipment Co., Ltd. Qingdao.
