Machine tool castings gray iron casting standards: Features:
Machine tool castings have good wear resistance and shock absorption. Since the graphite in cast iron is beneficial to lubrication and oil storage, it has good wear resistance. Likewise, gray cast iron is better at absorbing shock than steel due to the presence of graphite.
As a large-scale casting, machine tool castings must undergo heat treatment to improve their performance and improve the inherent quality of the 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 changes the microstructure inside the workpiece or changes the chemical composition of the surface of the workpiece. , endow or improve the performance of the workpiece. Its characteristic is to improve the intrinsic quality of the workpiece. In order to make metal workpieces have the required mechanical properties, physical properties and chemical properties, in addition to the reasonable selection of materials and various forming processes, heat treatment processes are often indispensable. Steel is the most widely used material in the mechanical industry. The microstructure of steel is complex and can be controlled through heat treatment. Therefore, the heat treatment of steel is the main content of metal heat treatment. In addition, aluminum, copper, magnesium, titanium, etc. and their alloys can also change their mechanical, physical and chemical properties through heat treatment to obtain different performance properties.
Integral heat treatment is a metal heat treatment process that heats the workpiece as a whole and then cools it at an appropriate speed to change its overall mechanical properties. The overall heat treatment of steel generally includes four basic processes: annealing, normalizing, quenching and tempering.
Machine tool castings
Annealing:
Types of annealing for heat treatment: Common annealing processes include: recrystallization annealing, stress relief annealing, spheroidizing annealing, complete annealing, etc. The purpose of annealing: mainly to reduce the hardness of metal materials, improve plasticity, to facilitate cutting or pressure processing, reduce residual stress, improve the uniformity of the structure and composition, or prepare the structure for subsequent heat treatment, etc.
Complete annealing and isothermal annealing:
Complete annealing is also called recrystallization annealing, generally referred to as annealing. This annealing is mainly used for castings, forgings and various carbon steels and alloy steels with hypoeutectoid compositions. Hot-rolled profiles are sometimes used in welded structures. It is generally used as the final heat treatment of some light workpieces, or as the preheat treatment of some workpieces.

Spheroidizing annealing:
Spheroidizing annealing is mainly used for hypereutectoid carbon steel and alloy tool steel (such as steel types used in manufacturing cutting tools, measuring tools, and molds). Its main purpose is to reduce hardness, improve machinability, and prepare for subsequent quenching.
Stress relief annealing:
Stress relief annealing is also called low-temperature annealing (or high-temperature tempering). This kind of annealing is mainly used to eliminate the residues of castings, forgings, welding parts, hot-rolled parts, cold-drawn parts, etc. stress. If these stresses are not eliminated, it will cause the steel parts to deform or crack after a certain period of time or during subsequent cutting processes.
