Why is there a crack in the design of machinery?

Machine tool castings will be broken or broken after rough heating or temperature. This is due to the irrational proportion of liquid metal during the scanning process, especially because of its low carbon and silicon content. In addition, at the time of the temperature process to eliminate internal tension, there will also be a train or a fracture resulting in the temperature of the tracking machine falling due to too rapid release.

Solution

1. In order to increase the violence and strength of machinery detection, many detection products that deliberately reduce the content of metallic elements such as carbon and silicon, this actually makes no sense. In order to ensure the machine hardware detection performance, the content of various metal elements must be proportional during the detection, and illegal production cannot be done just to save several hundred yuan per tonne.

Retract on machine device detection

2. When tempering machine-tools patterns to remove internal pressure, sometimes to improve working efficiency, patterns are released from the tungsten before reaching tungsten temperature, which will significantly affect the performance of the patterns and cause fractures or fractures on the patterns. Therefore, Tempering treatment should be performed in accordance with the tempering operation procedure of machine scanning equipment, and there should be no illegal operation to improve working efficiency. Machine hardware tracking cannot be broken or broken during the temper process.

Machine tracking HT250

Method to avoid trains in the batching process

To prevent trains in machine hardware tracking, a high carbon method can be used. Take an example of hardware detection HT250: the most logical chemical composition is C=3.25%-3.35%, Si=1.85%-2.10%, Mn=0.8%-1.2%, P< 0.12%, S=0.06%-0.10%, this is the experience accumulated by Hebei Huanuo Machinery Casting Co., Ltd. in the long-term production of machinery detection. For some large machine tracking equipment, the ratio of silicon to carbon can be adjusted correctly for the quality of tracking. The use of high and low carbon ratios can prevent congestion. The ratio of silicon to reasonable carbon must be controlled. is about 0.56%-0.61%.
