Heat treatment equipment is the best choice for energy saving industrial furnace

Induction heat treatment equipment has many advantages such as fast heating speed, energy saving, non-oxidative decarbonization, non-polluting environment and high production efficiency. These advantages are widely recognized by heat treatment workers, so they have developed rapidly in the past decade. Of course, this actual demand has also greatly promoted the development and technological improvement of domestic induction heat treatment equipment. Taking Changchun's China FAW as an example, the company has more than 100 induction heat treatment equipment, including 50 new or updated equipment in the past ten years, almost all of which are thyristor intermediate frequency equipment and IGBT ultra-audio equipment. At present, the weight of induction heat-treated parts of FAW's medium-sized trucks reaches 291.3kg, accounting for 52% of all heat-treated parts. Induction heat treatment has really lifted the half of the heat treatment.

These heat sources can be used for direct heating, or can be indirectly heated by molten salts or metals, or even floating particles. The heating temperature is one of the important process parameters of the heat treatment process. Selecting and controlling the heating temperature is the main problem to ensure the quality of the heat treatment. The heating temperature varies with the metal material being processed and the purpose of the heat treatment, but it is generally heated above the phase transition temperature to obtain a high-temperature structure. Normalizing is also called normalization or normalization, and its purpose is to improve the abnormal structure generated in the previous process by recrystallization and homogenization, thereby improving its mechanical properties and process performance. Normalizing can be used as a preliminary heat treatment equipment or as a final heat treatment equipment. For structural steels with machined parts, normalizing is mostly used as preparatory heat treatment equipment for subsequent cutting and final heat treatment equipment; for low carbon and low alloy steel plates, normalizing is used as the final heat treatment equipment to make The steel plate has the required structure, so that it has the required mechanical properties and technological properties.

Due to the technological transformation of large state-owned enterprises and a large number of heat treatment processing enterprises, the large demand for light industry and electrical product molds in coastal cities in East and South China, and the external cooperation of parts processing in emerging manufacturing industries, such as aviation, have emerged to purchase vacuum heat treatment equipment and seals. Furnace production line-based equipment update wave. The heat treatment of gasoline engines, diesel engines, gearbox parts, and basic parts in the automotive, railway, shipbuilding, wind power, weapons, drilling, mining and other industries has also basically achieved the push rod furnace, roller rod furnace, chain plate furnace, mesh belt furnace, The heat treatment equipment mainly including sealed multi-purpose furnace, transistor induction power supply and automatic quenching machine tool is updated. The upsurge of technological transformation and upgrading of equipment in enterprises has created a very prosperous scene in the heat treatment equipment market. The equipment renewal rate of key enterprises has reached over 70%.
