Heat treatment is a kind of metal hot processing technology, which is changing the material surface or internal chemical composition and organization for the metal by means of heating, heat preservation and cooling. The combustion fan, high temperature circulating fan and cooling fan are the often used types in the heat treatment process.
The fan is using to provide combustion air to the heat treatment furnace to increase the furnace temperature and improve the furnace efficiency. Centrifugal fans with large air volume and high temperature resistance are often used.
When the temperature is at a certain point, the hot processing material should remain at that temperature for a certain amount of time. High temperature circulating fan is mainly used in the process of heat preservation to keep the temperature constant in the furnace. High temperature resistance is vital.
According to the cooling rate, the cooling process is divided into annealing, normalizing and quenching. Cooling fans are used for the material cooling.
London Fan has participated in many heat treatment projects in iron & steel industry and non-ferrous metal industry, including Yingkou Zhongwang project, Canada Zhongwang project, FABIO project, Hangzhou Zhongjie Industrial Furnace project, New Jiangnan furnace industry project, Keda machinery project, etc. The fans performed well in each project and are widely praised by customers.
