(Summary description)When the foundry manufactures bed casting products, as a large-scale casting, it must undergo heat treatment to improve its performance and improve the inherent quality of cast iron castings. Metal heat treatment is one of the important processes in mechanical manufacturing. Compared with other processing processes, heat treatment generally does not change the shape and overall chemical composition of the workpiece, but by changing the internal microstructure of the workpiece or changing the chemical composition of the surface of the workpiece. , To give or improve the performance of the workpiece.

When the foundry manufactures bed casting products, as a large-scale casting, it must undergo heat treatment to improve its performance and improve the inherent quality of cast iron castings. Metal heat treatment is one of the important processes in mechanical manufacturing. Compared with other processing processes, heat treatment generally does not change the shape and overall chemical composition of the workpiece, but by changing the internal microstructure of the workpiece or changing the chemical composition of the surface of the workpiece. , To give or improve the performance of the workpiece.

 

Foundry manufacturers should pay attention to the following techniques and methods in the production process:

1. The particle size of the alumina should not be too fine, preferably sandy alumina, the anode sealing material should be reduced when cutting, and the windows should be closed during processing.

2. When replacing the anode, the material on the old electrode should be cleaned, and the aluminum oxide on the residual electrode should be cleaned up.

3. Control the precipitation to prevent excessive precipitation and hardening of the precipitation.

 

The high production efficiency of foundries is mainly manifested in the following four aspects:

1. It involves a wide range of knowledge, such as the inspection of alloys, casting technology, molding materials, casting equipment and production process.

2. There are many reasons for casting defects. One type of defect can be caused by multiple reasons, and one cause can cause several types of defects.

3. The restriction of technical measures, such as adopting a measure to prevent a certain type of defect, but it may lead to another type of defect.
