For the second type of heat treatment, the Al-Qaida undergone significant changes can be roughly divided into five categories: (1) softening annealing: The main purpose is to decompose carbide, will reduce its hardness, and improve the processing performance, and for ductile iron , its purpose is to get more ferrite. (2) normalizing: The main objective is to obtain pearlite and sorbite organization to improve the mechanical properties of the casting. (3) quenching: mainly in order to obtain a higher hardness or abrasion strength, while to the very high surface wear properties. (4) surface hardening treatment: mainly to obtain surface-hardened layer, the surface at the same time give very high abrasion resistance. (5) The precipitation hardening process: mainly for high strength and elongation are not thereby causing drastic changes. (6) surface casting defects treatment: sometimes we do not have many flaws, it is not necessary into a larger costs, we can repair some of Putty good, convenient and simple, such as ferrous materials, we can use ( Jin Su to) JS902 repair click on it, could ever again be able to put the future, so you can save the cost of producing anchor for our manufacturers, so that our casting manufacturers to put more money into improving the quality of the product itself , allowing users to create more wealth. From the historic casting technology into today's modern casting techniques or liquid solidification forming technology not only with the deepening and development of crystallization and solidification of metals and alloys theoretical studies, various solidification technologies emerge constantly developing (a) coagulation theory crystallization and solidification process is the formation of the core cast anchor pattern, which determines the formation of casting defects in the organization and also determines the performance and quality of the casting. The past 30 years boat anchor, by means of physical chemistry, metallurgy, non-equilibrium thermodynamics and kinetics, advanced mathematics and computational mathematics, research from the heat transfer, mass transfer and solid-liquid interface aspects, the metal solidification theories a lot of development, which not only makes people solidification process and organizational features many conditions have a thorough understanding of, and prompted a number of proposed solidification technology and liquid solidification forming methods, development and production applications. For example solidification theory has established a number of function casting cooling rate and product size and grain size and mechanical properties of casting between, so as to control the casting process parameters and mechanical properties of casting provided. Development control solidification process (b) solidification technology is an important way to develop new materials and improve the casting quality. Solidification, rapid solidification technology, access to composite materials, semi-solid metal casting forming technology, and so is the focus of the representative. And improve the application of computer technology, but also on the chemical industry, machinery manufacturing, manufacturing methods and technology development is closely related to the mechanical anchors accessories _ Chen Hua (Online) _ Anchor Qingdao Chen Hua Machinery Co., Ltd. provided.
