What is the basic information of agricultural machinery castings?


Agricultural machinery casting products are large castings, and in fact, they need to be heat-treated to improve the self-use performance and internal quality of cast iron parts. Metal heat treatment is an important process in machinery manufacturing. The following is some basic information about agricultural machinery castings.

The heat treatment of agricultural machinery castings generally does not change the shape and overall chemical composition of the workpiece, but changes the microstructure inside the workpiece or changes the chemical composition of the workpiece surface, thereby giving the workpiece performance. The characteristic of agricultural machinery castings is the internal quality of the workpiece. Here, everyone needs to know that in order to provide the mechanical, physical, and chemical properties required for metal workpieces, in addition to the rational selection of materials and various forming processes, the heat treatment process is often the same. Steel is widely used in the mechanical industry. The microstructure of steel is complex and can be controlled by heat treatment. Therefore, you will find that the heat treatment of steel is the main content of metal heat treatment. In addition, aluminum, copper, magnesium, titanium, and their alloys can change mechanical, physical, and chemical properties through heat treatment to obtain various properties. Moreover, overall heat treatment is a metal heat treatment process in which the workpiece is heated as a whole and then cooled at an appropriate rate to change the overall mechanical properties. The overall heat treatment of steel includes four basic processes: annealing and purification. Agricultural machinery castings are made of excellent gray cast iron, and 45% steel is smelted to improve the rigidity of mechanical castings.


Of course, it is now very common for customers to make ductile iron. The rigidity of ductile iron is better than that of gray cast iron, but its shock absorption effect is very different from that of gray cast iron, and the casting cost is much higher than that of gray cast iron. Therefore, ductile iron is not suitable for the main parts of machine tools, but is more suitable for casting machine tool tables. In general, the casting cost of agricultural machinery castings is actually very low, and gray cast iron parts have good performance and are easy to cast into various complex structures. It has good shock absorption performance, which helps prevent machine vibration and reduce operating noise. The tensile strength is lower than that of steel, but the compressive strength is similar to that of steel. The tensile strength of most machine tools is not high enough to meet performance requirements. In addition, agricultural machinery castings also have good lubrication performance. This is because the micropores of gray iron atoms can hold more lubricating oil, and the carbon they contain is self-lubricating. Also, because cast iron is easier to rust than steel, it is easier to maintain the accuracy of machine tool guideways. Machine tool castings have good dimensional stability and will not deform the machine tool body, which helps maintain the accuracy of machine tool castings for a long time.
