What is the essence of the metal heat treatment process?

What is metal heat treatment?

Metal heat treatment is a process to control the properties of metal workpiece by changing the microstructure of metal material surface or interior by heating, holding and cooling the metal workpiece in a certain medium.

metal heat treatment furnace is one of the important processes in mechanical manufacturing. Compared with other machining processes, heat treatment generally does not change the shape of the workpiece and the chemical composition of the whole, but by changing the microstructure of the workpiece. Or change the chemical composition of the surface of the workpiece to give or improve the performance of the workpiece. Its characteristic is to improve the internal quality of the workpiece, which is generally not visible to the naked eye. Metal heat treatment technology can be divided into three categories: integral heat treatment, surface heat treatment and chemical heat treatment. According to the different heating medium, heating temperature and cooling method, each class can be divided into several different heat treatment processes. Different microstructure and properties of the same metal can be obtained by different heat treatment processes. Iron and steel is the most widely used metal in industry, and the microstructure of iron and steel is the most complex, so there are many kinds of heat treatment process of iron and steel. Heat treatment usually consists of three processes: heating, heat preservation and cooling, sometimes only heating and cooling. These processes are intertwined and uninterrupted.

The main purpose of tempering is to eliminate the quenching stress and obtain the required microstructure. Tempering is divided into low temperature, medium temperature and high temperature tempering according to the different tempering temperature. Tempered martensite, tritrite and sorbite were obtained respectively. The heat treatment combined with high temperature tempering after quenching is called quenching and tempering, which aims to obtain comprehensive mechanical properties with good strength, hardness, plasticity and toughness.

The heat treatment equipment technology of Hebei Yuantuo mechanical and electrical factory has matured after nearly 10 years experience precipitation. The main electronic components of our factory are all imported brand products. The induction heat treatment equipment of Yuantuo mechanical and electrical factory is stable and reliable in quality and complete in style. It is sold at home and abroad.
