The technical requirements of the surface forged surface, including the surface roughness and surface defects. During the forging process, due to the effects of surface metals oxidized, foreign objects embedded, uneven metal flow, uneven surface surfaces, and improper sub -silver auxiliary processes

Aluminum alloys can be heated before forging with various heating equipment, such as resistance furnaces, gas furnaces, fuel furnaces, inductive heating devices, and dance particles.

Forging heating requirements1. Under the temperature and internal stress allowed by metal materials, it is quickly heated to the predetermined temperature to improve efficiency and save energy.2. Try to reduce the absorption of harmful gases such as oxygen, hydrogen, and nitrogen in heating metals,

An important part of ensuring the quality of thermal treatment is the uniformity of the forging temperature temperature. For most low -alloy steel quenching. The temperature accuracy of the Antidization can be controlled within the range of ± 15 ° C. For thermal treatment of high -intensity aluminum

Compared with ordinary mode forging, the main advantages of precision die forging are: less than mechanical processing, even zero; raw material savings; high labor productivity: low production cost; high dimensional precision mold forging, dimensional tolerance The size tolerance of ordinary die for

The preparation of aluminum alloy forgings before forging includes the selection of raw materials, calculation, blanking, heating, deformation, design of equipment and molds. Before forging, the lubrication method and lubricant should also be selected.Forging materials have a wide range of surfaces,

First, the characteristics of fine forging1. Greatly reduce the cost of product parts. The machining allowance of forgings is small, the public service is small, and the surface roughness value is small. Machining can partially or completely replace parts, save data and machining time, and improve l

Penetration Testing After the surface of the test piece is coated with a penetrant containing fluorescent dyes or coloring dyes, under the action of capillary tubes, after a certain period of penetration, the penetrant can penetrate into the surface opening defects; after removing the excess penetra

​Ultra-high-strength aluminum alloys generally refer to aluminum alloys with a yield strength of more than 500 MPa, and the common ones are 7XXX series super-hard aluminum.

Processing characteristics of 7075 aluminum pipe 7075 aluminum is called ultra-high strength aluminum alloy. The yield strength of the alloy is close to the tensile strength, the yield ratio is high, and the specific strength is also high, but the plasticity and high temperature strength are relativ

High-strength duralumin 2A12 aluminum forgings2A12 aluminum alloy is a kind of high-strength hard aluminum, which can be strengthened by heat treatment. It has medium plasticity under annealing, just quenching and hot state. 2A12 aluminum alloy has good spot welding weldability. Tendency; 2A12 alumi

According to preliminary statistics, in 1985, aluminum forgings accounted for 0.5% (18,000 tons) of the world's total forging production, and in 2008 it rose to about 18%. At present, the world's consumption of forgings is about 4.5 million tons/year, of which aluminum forgings are about 800,000 ton
