Guangdong alloy steel castingAlthough processing is an old pressure processing method, it has characteristics that other pressure processing methods do not have, so it still plays a proper main effect. Due to the development of modern machinery manufacturing and other industries, casting methods are constantly innovating and advancing.

In the joint metallurgical industry, especially the excellent steel metallurgical plants, a steel casting workshop is often built at the same time as the steel rolling workshop. This is because many excellent alloy steel ingots with low plasticity are mostly required to be rolled after casting and billeting.

In machinery manufacturing and other industries, with regard to key components with heavy load, severe operating conditions, and high strength requirements, machining can only be carried out after the blanks can be manufactured by casting methods. Such as the rolls and herringbone gears of large rolling mills, the rotors, impellers, and guard rings of steam turbine generator sets, endless hydraulic cylinders and columns, locomotive shafts, crankshafts and connecting rods of cars and tractors, etc., are all precision castings. Into. As for parts weighing more than 150-200t in heavy machinery manufacturing, other pressure processing methods are beyond the reach.

At present, the development of cars and tractors, shipbuilding, power station equipment, as well as the new aerospace and nuclearGuangdong carbon steel castingIncreasingly high demands have been placed on machining, such as huge special castings, fine castings with little or no cutting processing, castings with messy shapes and extremely high mechanical properties, etc.

Compared with other processing methods, casting has the following characteristics: precision casting processing

The quality of castings is higher than that of castings and can accept large impact effects, and the plasticity, toughness and other mechanical properties are also higher than castings and even higher than rolled parts. Therefore, castings should be used for all major machine parts.

To save raw materials, such as the 17kg gross weight crankshaft used in cars, the chips account for 89% of the axle weight when the rolled billet is used for cutting; and when the die casting billet is used for cutting, the chip only accounts for 30% of the axle weight, which also shortens the processing. One-sixth of the working hours.

High production efficiency. For example, using two hot die casting presses to mold radial thrust bearings can replace 30 active cutting machine tools; when using a top casting active machine to produce m24 nuts, the production rate is 17.5 times that of a six-axis active lathe.

comfortableGuangdong Stainless Steel CastingIt is suitable for single-piece and small-batch production, with great flexibility, and free casting is indispensable in normal machine repair factories.

It is necessary to point out that casting is an initial production method, the production rate is low compared with rolling, and the level of mechanization and automation needs to be further improved.
