How are wear-resistant steel balls produced? Air hammer forging steel ball.

The traditional forging wear-resistant steel ball is produced by air hammer forging process, and the raw materials are pressed; Huamin steel ball develops a new generation of forging wear-resistant steel ball production technology-rotary cutting and roll forging; 1, raw material preparation; 2, numerical control transmission; 3, steel preheating; 4, rotary cutting roll forging into balls; 5, numerical control isothermal; 6, drum quenching; 7, heat preservation and tempering; 8, packaging and warehousing; Huamin Steel Ball Company strictly controls every technological process in the production process. At present, the total number of enterprises producing steel balls in China shows according to different statistical data: general; These enterprises use various methods to produce steel balls. The traditional forging wear-resistant steel ball is forged by air hammer. The raw materials are cut according to a certain size, preheated, and forged into balls by air hammer. Under this process, the quality of steel balls is greatly influenced by the labor proficiency of workers, and the quality of steel balls is uneven and cannot be guaranteed.

A new generation of forging wear-resistant steel ball production process-rotary cutting and rolling forging process has been developed, and its process flow is as follows:

1, raw material preparation. According to the size of steel balls to be produced, round steel with suitable model is selected as raw material.

2, numerical control transmission. For example, raw materials are placed in a CNC conveyor and transported at a uniform speed at a specific speed.

3, steel preheating. The steel ball is heated to a specific temperature by an intermediate frequency induction furnace, and the numerical control drive ensures that the steel is heated evenly.

4, rotary cutting and rolling forging into balls. Rotary cutting machine automatically cuts round steel into a certain length, and the round steel is forged into balls by roll forging machine.

5, numerical control isothermal. This is an important step to ensure the reasonable hardness of wear-resistant steel balls before quenching.

6, roller quenching. Strictly control the quenching time and temperature.

7. Heat preservation and tempering. Eliminate the internal stress of steel ball and reduce the crushing rate of wear-resistant steel ball in use.

8. Packaging and storage. It is particularly important to note that wear-resistant steel balls should not be stored in the open air for a long time when packed in ton bags.
