Mesh belt tempering furnace

Structure of mesh belt tempering furnace:

The main structure of the mesh belt tempering furnace is composed of shell, lining, Muffle, mesh belt, motor transmission and electric control system.

The shell and cover of the furnace are mainly made of steel plate bending and welded, and have a beautiful appearance.

The lining of the furnace adopts ultra-energy-saving structure: the insulation layer of the bottom lining of the furnace is made of thermal insulation bricks with a bulk weight of 0.8, and the insulation layer on both sides is made of aluminum silicate fiber, and the surface of the furnace shell is covered with a layer of asbestos board (low thermal conductivity); The thermal insulation layer of the furnace cover adopts the whole fiber needled blanket module, which is anchored on the steel plate of the furnace cover by a special method (commonly known as the suspended ceiling structure). This structure has many advantages such as good heat insulation effect, low energy storage, small heat loss, good thermal shock, convenient inspection and so on. Greatly improve the service life of the lining. The power loss of empty furnace, the temperature rise of furnace wall and the average temperature of furnace are better than the scale.

Muffle is made of heat-resistant stainless steel plate bent into a corrugated shape and welded, which has high high temperature strength.

Motor stepless speed regulation operation, variable frequency speed regulation control, through the main drive sprocket drive, and auxiliary sprocket, limit compression wheel fixed, tighten the mesh belt. Equipped with power off protection device, the use of manual power tube rotating mesh belt, to prevent due to power off and stop the operation of the mesh belt, resulting in the furnace workpiece overburning, mesh belt burning and other situations.

The heating temperature control instrument adopts the intelligent temperature control instrument of Japan SHIMA/SHIMA Electric Company. The instrument is equipped with self-adjusting and scaling PID operation module, which can effectively prevent temperature overrush. At the same time, the instrument can perform function selection, configuration and parameter setting, and display the set value and actual value in digital mode. The main heating adopts SCR series combined three-phase thyristor power controller, which adopts continuous non-on-off type, which is not the traditional electrical on-off type during control, but continuously and automatically adjusts the heating power according to the temperature control requirements. High precision for high power temperature control, no noise, no interference to the internal power grid.
