Is the production cycle of forgings long?

Is the production cycle of forgings long? A lot of purchasers have this question? So xiaobian will tell you in detail.

Forgings single or small batch production of large forgings, production preparation complex, long production cycle.

1. The preparation of metallurgical fittings is complicated. For example, the rotor of a 600MW generator, from the steel ingot mold of smelting and casting, lifting sprig, transportation auxiliary, to the large auxiliary for forging, heat treatment and rough processing, its total weight, production time, production cycle and production cost greatly exceed the production of basic parts.

2, large forging before the production of a variety of subject research and process planning and implementation, the cycle is also long.

3. Due to the large weight and shape of the large forgings, the production cycle is long. Including charge preparation, smelting, ingot, forging, first heat treatment, second heat treatment, rough processing and various testing.

4. Forgings generally require high quality and harsh technical conditions. This is especially true for power station forgings. It has very strict standards and requirements for the chemical composition (including gas content), mechanical properties (tensile and impact properties), non-destructive testing (ultrasonic and magnetic particle testing), metallographic testing (grain size, inclusion) and size and surface roughness of steel.

The production of large forgings from smelting, ingot, forging, forging heat treatment to performance heat treatment, to go through a lot of processes, each process affects the quality of forgings, a little deviation may cause defects, so it is difficult to produce.
