Annealing furnace
aboutWhat is an annealing furnace?
An annealing furnace is a furnace that evenly heats metal products to a specific temperature and then holds that temperature, before slowly cooling the products to remove residual stress caused by the machining process. This results in a uniform metal organization. Glass can also be treated in an annealing furnace to restore its tissue arrangement and make it suitable for use as optical glass. Sun Furnace Co., Ltd., a manufacturer of gas-tight Annealing Furnaces, can provide custom-made furnaces to meet customer requirements.
featureFeatures
Precise temperature control.
The furnace temperature can be accurately controlled for desired product performance and characteristics through simulations of heat calculation and heater capacity calculations during the design stage.
Various atmosphere gases can be used.
The furnace is designed with a unique sealing structure to prevent air infiltration and gas extrusion, allowing for the use of special atmosphere gases.
