Semi -solid -state mold forging process

During the metal solidification process, the early crystal grows in the form of a branch crystal. When the solid phase rate reaches about 20%, the lending crystal forms a continuous network skeleton.
Macro liquidity loss. If a stirred stirred during the metal coagulation process, the ribbon crystal network skeleton that is easy to dry during the conventional solidification process will be broken and it becomes a scattered particles suspended in the remaining liquid phase. This alloy prepared by mixing is generally called a non -Zhi crystal semi -solid billet. This semi -i -type semi -solid billet still has good liquidity when it is 50%to 60%. Metal forming can be implemented with conventional forming processes such as die casting, mold forging, and extrusion, which is 2.It has developed a new metal processing technology -half -cycle metal forming technology. The so -called semi -solid mold forging is a new process between solid formation and liquid formation. It is a semi -solid -state that heats the semi -solid bad material to about 50%of the volume liquid phase, and then the mold forging The required finished parts. There are many unique advantages of semi -ancient mold forging: the contraction of the parts in the mold is small, it is easy to settle near, and the processing capacity is reduced; the surface of the semi -solid mold forging parts is smooth, the internal tissue is dense, and the grains are small; Performance is not easy to clamp the air, macroholes and micro -pores are much less than conventional castings; the molding temperature is low and the mold life is long.
very long. In the past 10 years, semi -solid forming technology has been widely used abroad. (2) Gradually become a new field of development of advanced industrial countries, and is called by experts and scholars as the new generation of emerging metal forming technology in the 21st century. It is predicted that for a long time, the main market of semi -solid formation will be the automotive industry, and automotive aluminum alloy parts are the most successful and widely used. The United States has built several aluminum alloy semi -solid -state mold T factories. Among them, the American AEMP (aluminum engineering metal process) company cooperated with Superior T. Industry. Car wheel factory. The use of semi -solid -state molds instead of low -Casting production of ZL101 aluminum alloy wheels can not only reduce processing volume, improve productivity, but also improve mechanical properties and reduce quality. The domestic research on this technology started late. Although there were some research results reports, there were very few actual applications. The half -antique font mold forging aluminum alloy hub is a high -tech with a series of advantages. It is expected that a newly -built aluminum wheel factory will have a semi -solid -state molding factory to improve the competitiveness of domestic cars in the international market.
