Annealing Furnaces for Binding wires (Suit for annealing steel wires in seal condition) 

Model: RJ-90-9   Ф950 x 1200mm

Specification

Structure Introduction:

The Annealing Furnace consists of furnace shell, furnace lining, heating element, furnace cover and lifting parts etc.
For the lining of the fiber structure, namely the side wall for fiber block structure. The high aluminum brick heavy and light brick in the bottom part of the pressure, and the insulating brick masonry.

Heating elements:
The furnace body (side wall) part of all the use of resistance band (material 0Cr21Al6Nb), the heating element of the structure of the use of the current unique advanced technology.

The original fiber lining heating element for hanging with positioning pieces of metal from the furnace shell steel structure into the furnace inner metal element and method of porcelain sleeve rod, so that in the condition of high temperature in the furnace, the metal positioning piece there are a large part of heat into the furnace shell steel structure, thermal short-circuit phenomenon is serious the heat loss. At present, our company adopted the way directly to the whole fiber fiber blanket into furnace wall (fiber compression 35~40%), using a special ceramic ceramic and ceramic screw tapping screw gasket, can quickly and easily the resistance belt is fixed on the furnace wall, this method does not produce heat loss, convenient construction, the use effect is the best. The maintenance is also very convenient. This method is widely used in all over the world.
The standard of refractory fiber lining material of low density, fire resistance of less than 1200 DEG C, the heat shrinkage will not expand, and a small coefficient of thermal conductivity (0.13Kcal/mh DEG C, and 0.6 fiber lightweight brick for 0.3Kcal/mh C), less heat (full fiber furnace wall for 17261KJ/m -, and 453633KJ/m - furnace refractory brick wall) of the superior performance. Compared with the same size of the brick wall of the furnace lining structure, fast heating speed, the installed power can be reduced by more than 20%, the energy saving effect of 20~30%.
Furnace tank with stainless steel (1Cr18Ni9Ti, 8mm thick) welded in furnace.
The lifting the lid to complete, by mechanical lifting mechanism to translate sound, open and close the lid lifting accurately. Just press the corresponding button on the control cabinet, lifting.
Overall design of control system:
The electric appliance control system of the well type furnace is composed of a power supply system, a temperature control system, a motion control system, and a temperature control system.
Power supply system:
The power supply of the device is controlled by a high power circuit breaker, which has the functions of short circuit and overvoltage protection to ensure the safe operation of the power supply line.
Temperature control system:
The 2 section of the furnace automatic temperature control, temperature control using PID regulator, the main control instrument using the Shanghai national dragon temperature control table (TCW-32B), and by heating the partition requirements for matching. The temperature recording meter is required to record the temperature curve automatically.
Control of motion control:
The equipment can improve the function of transmission control, interlock and system protection, and can be used as backup support for temperature control system. With interlocking function, when the furnace cover is closed in the normal state, the main circuit can be heated, and the temperature control system can be closed loop operation.

Warranty

One Year & Lifelong service

Within one year, if it is damaged itself, except for man-made damage, we will be responsible. Excluding electrical appliances and vulnerable parts.
One year after, our service will continue, with accessories provided by us and technical support by us, but the cost of accessories including the shipping cost by customers.
