There are many methods for surface hardening treatment, and common processes include induction hardening, flame hardening, carburizing and quenching, nitriding, etc. Each process has its own unique characteristics and scope of application. Choosing the appropriate process according to the specific requirements of the column lift parts can maximize its surface performance.
Induction hardening
Induction hardening is a surface hardening method that heats the metal surface by electromagnetic induction and then cools it rapidly. The advantages of this process are fast heating speed, strong controllability, and only heating the surface of the component without affecting its internal structure, so it can maintain the overall toughness and strength of the component. Induction hardening is suitable for parts that require high surface hardness and wear resistance, such as transmission gears and bearing seats. These parts are subjected to high-frequency friction during the operation of the column lift. If the surface hardness is insufficient, they are very easy to wear, resulting in reduced transmission efficiency or equipment failure.
Flame hardening
Flame hardening is similar to induction hardening, but uses a high-temperature flame to heat the metal surface and then cools it rapidly. Flame quenching has the characteristics of simple equipment and flexible operation, and is suitable for processing large or complex-shaped parts. Flame quenching is widely used for surface hardening of large support columns or lifting platforms. These parts are usually complex in shape or large in size. Flame quenching can enhance the surface hardness and wear resistance without changing its overall structure.
Carburizing quenching
Carburizing quenching is to contact low-carbon steel or alloy steel parts with carbon-containing media at high temperature, so that carbon atoms penetrate into the metal surface, and then quench, so as to form a high-carbon hardened layer on the surface. This process can significantly improve the surface hardness and wear resistance of the parts while maintaining the toughness inside. Carburizing quenching is particularly suitable for parts that require high wear resistance and fatigue resistance, such as transmission shafts and gears. These parts are subjected to huge stress and frequent friction during operation. After carburizing quenching, their surfaces can maintain high hardness for a long time and extend their service life.
