Large shaft forgings refers to the large forging equipment forged on the body size and weight of a single piece of heavy forgings, which is mainly large free forgings. In the heavy machinery manufacturing industry, usually forged in more than l0000KN forging press or 5t forging hammer on the forging of heavy forgings, known as large forgings. At present, the single weight of large shaft forgings has reached 250t, and the weight of large forging ingots reached 600t.

Most of the large shaft forgings are key parts of various large machinery and equipment, for example, thermal power generation equipment in the hydraulic turbine spindle forgings, metallurgical industry in the rolling mill roll forgings, the shipbuilding industry in the crankshaft forgings, rudder forgings, heavy machinery manufacturing industry in a variety of large shaft forgings. Therefore, the production progress of large shaft forgings is of great significance to the development of the national economy, and its scientific and technological level, production capacity, economic and technical indicators, often become an important symbol to measure the level of industrial development of a country.

The main characteristics of the production of large shaft forgings are.

(1) Strict quality requirements: Since most of the large shaft forgings are key parts in machines, generally with special working conditions and complex stress conditions, their quality must be reliable and their performance must be excellent in order to ensure safe operation. With the development of industrial machines to high performance, high parameters and large size, the technical conditions and quality level of forgings are increasing. However, the improvement of the metallurgical quality of raw materials, the optimization and control of forging and heat treatment technology, and the progress of quality analysis and testing technology are not yet compatible with it, so the problem of how to improve the quality of large shaft forgings has become the main contradiction in the production of large shaft forgings.

(2) Complex process: The production process of large shaft forgings includes: smelting, ingot casting, heating, forging, rough machining, heat treatment, etc.. There are many process links, long cycle, continuity, collective labor and complex production technology.

(3) High production cost: Large shaft forgings consume a lot of raw materials, energy, labor and tools, have a long production cycle, and occupy a lot of large equipment, so the production cost is high. Therefore, it is technically and economically important to improve material utilization rate, reduce consumption and scrap rate.

Forged steel shafts are created through a manufacturing process that involves the shaping of the shaft Forgings using localized compressive forces. The forging process is initiated when a piece of steel is struck repeatedly with a hammer or squeezed with a press.

How are steel shafts manufactured?

The most common process used to manufacture shafts is via CNC turning. Using this technique, workers or automated processes affix or clamp bars of materials to chucks and rotate them. While rotating, specialized tools use cutting and other subtractive processes to create and shape the end product.

What type of steel is used for shafts?
The material used for ordinary shafts is mild steel. When high strength is required, an alloy steel such as nickel, nickel-chromium or chromium-vanadium steel is used. Shafts are generally formed by hot rolling and finished to size by cold drawing or turning and grinding.

How many types of shafts are there?
Types of shafts? Mechanical shafts are broadly categorized into the following four types. Axle shaft – An axle is a non-rotating version of a shaft that supports elements such as rotating pulleys and wheels but carries no torque. An axle is a static beam and can be analyzed as one simply supported beam.
