The atmosphere box furnace is divided into the following parts,

1. Furnace　　

The hearth is built with mullite poly light bricks, and the upper and lower sides of the hearth are made of silicon carbide panels. The temperature in the furnace is conducted by the heating elements through the silicon carbide panels during the heating process (dark fire heating), and the temperature is more uniform. The furnace shell is sealed. In order to improve the service life of the gasket, a circulating water cooling jacket is installed at the door of the furnace to reduce the temperature of the seal. The air inlet is set at the bottom of the furnace, which is preheated by the heating cavity and enters the furnace in multiple places, and the exhaust is discharged through the back of the furnace top. Ensure the atmosphere in the furnace is uniform and reduce the temperature difference in the furnace. A gas flow meter is installed on the gas path to control the flow of the atmosphere in normal use.　　

2. Cooling　　

The furnace door adopts circulating water cooling. Equipped with water inlet and outlet connections.　　

3. Electric 　　

The electrical part adopts an integrated structure with the furnace body, and the entire electrical components are installed on the side of the bottom of the furnace body, which is compact in structure and small in space. The temperature controller is installed on the side panel of the furnace body for intuitive observation and convenient adjustment. The temperature controller has PID adjustment function, which can automatically track and set the best PID value, and can set the measurement indexing password at will. At the same time, it has a compensation function. The furnace temperature is consistent with the displayed value. The temperature control method: adopts German Siemens technology, with soft start, soft shut-off, SCR phase-shift voltage regulation control, 0~98% output adjustable, various instrument switches on the panel, etc. Chinese signage.
