Usage

This series mesh belt anneal furnace is continuous operating furnace. It is used for annealing, tempering and drying etc of the mass produced small and medium-sized bearing ring, roller, tapping screw in protection atmosphere.

Feature

Temperature Uniformity

Using both sides to heat, the stainless steel air deflector design and refractory steel multiblade fan type blower greatly improve the uniformity of the furnace temperature. There is no dead point when heating the workpiece. Temperature uniformity ± 5,temperature control accuracy ±1. The product has attained national Grade I standards.

Low energy consumption

The fiber acupuncture blanket module has good insulation effect, low energy storage, low heat loss.

High degree of automation

Full automatic temperature and action control, perfect alarm device and lock protective device.

Structure

The main structure composes of the furnace shell, the furnace lining, muffle, net belt, transmission system and electrical controlled system.

The furnace shell and the furnace cover are mainly made by bending and forming of the steel plate and then welding with the shaped steel, whose surface is fine artistic.

The furnace lining uses a ultra energy conservation structure, including the insulating layer of the hearth bottom lining uses a special insulating brick, the furnace covers insulating layer is made from the entire textile fiber acupuncture blanket module, which has many advantages, such as good heat insulation effect, low energy storage, small heat losses, good thermal shock resistance, convenienced overhaul and so on, which improves the furnace lining life-span greatly. And the parameters of the electric furnaces power loss when its empty, the rised temperature of the fire walls and furnace temperature uniformity all surpass the national standards.

The muffle is welded by the heat-resisting stainless steel plate which bends to the ripple shape. It still performs good under high temperatures.

The electric motor running under the stepless speed regulation and the frequency control, setting and frapping the belt through the main transmissions chain wheel transmission, together with assisting chain wheel, the pin spacing pinch roller. It also equipped with power-down protector. It can roll the net belt manually when the power is out, incase of the halt of the net belts running lead to the burnout of net belt and woekpiece inside.

The heating temperature control unit table uses Japan (SHIMA) Corporations intelligence temperature control unit. This instrument has arranged self-adjust and the standard PID operation module which could effectively prevent the overshoot of the temperature, at the same time, this instrument is equipped with functions choice, functions disposition and parameter set, and the set value and the actual value can be shown by figure. The major heating instrument uses the SCR series assembled three-phase thyristor power controller, adopting continuously the non-make-and-break type, which is not the traditional electrical make-and-break type, but continually adjust the heating power automatically according to the request of the warm controllers. It is in high precision when it faced high-power temperature controller. And it produced no noise and has nil interference to the inner power network.
