Third, the structure brief
The furnace structure is mainly composed of furnace body, heating element, lifting mechanism, rapid cooling device, and temperature control system.
Furnace shell made of steel and steel plate welded together, with refractory brick into the furnace to improve the furnace insulation performance.
The heating element is placed on the furnace wall with OCr25Al5 resistance wire.
The furnace has a heat-resistant plate welded into a furnace. The upper part of the furnace tank is equipped with a drainage water inlet device, an air intake device, which can be cooled down according to the requirements of the user, and the water cooling device is installed.
In order to make the workpiece evenly in contact with the gas, the furnace shell is equipped with a fan (anti-corrosion all-sealed fan), used to force the air circulation, so that the furnace temperature and gas uniform. There is a leak-proof seal on the fan hub and cooled with cooling water.
The lift of the lid is provided with hydraulic lifting mechanism, the power provided by the 10/25 hydraulic device.
When the lid is to rise, as long as the start of the hydraulic device, the lid that is slowly rising; for the furnace lid down, as long as the loose hydraulic device in the internal thread valve, the lid is slowly decreased. In the lifting shaft, there are two limit switch, when the lift shaft rise, the following a limit switch automatically cut off the electric fan power, so as to avoid the risk of operation; when the lid up, the above a limit automatically cut off the hydraulic device power , To prevent the lift shaft out of the cylinder accident
2, described separately
A, the furnace is divided into furnace shell, refractory materials, heating elements, panels, thermocouple and lead seat.
1), the furnace shell from a variety of steel and steel plate made of drum.
2), the furnace by the refractory materials, insulation materials, etc., the bottom of the refractory material using ultra-lightweight clay brick, heavy brick masonry.
3), the heating element is made of Shougang made of chrome and aluminum.
4), the panel with 45 # steel processing, fixed with screws.
5), the furnace side of the mouth with a few lead out, thermocouple seat hole.
B, ventilation mechanism is divided into motor, fan shaft, bearing, fan, wind plate, deflation device, sample device, panel and insulation box.
1), the motor is fully sealed motor.
2), fan shaft with refractory steel finishing.
3), bearing imported parts, with heat, wear characteristics.
4), the furnace wind shield and guide duct made of stainless steel.
5), the bleed valve for the exhaust gas from the furnace, the pressure can be through the exhaust pipe on the thread to adjust the valve.
6), the sample device is used for sample parts, the sample tube with stainless steel tube welded carbon tube jacket to form a sealed water jacket device, can be used for circulating water cooling, to prevent deformation of the sample tube.
7), the panel is made of 35mm steel plate, the upper part of the panel is welded with a hammer bucket, which is equipped with a ventilation mechanism, and the plane of the oblique hammer barrel is connected with the fan screw.
8), all the insulation box made of stainless steel welding, containing insulation materials.
C, the heating element is divided into heating element resistive tape, drawing rod.
1), the heating element material is 0Cr25Al5 iron chrome belt.
2), lead out the material using stainless steel 0Cr18Ni9.
D, lifting mechanism using hydraulic system type, by the 0.75kw motor, B10 gear pump and DC relief valve, stop valve, solenoid valve and other components.
E, the furnace is made of imported 316L stainless steel thick welding parts, the bottom of the use of head-shaped stiffeners, the upper part of the flange by the metal processing square hole, square hole is installed sealed graphite packing ring. In the lower side of the square hole welding a circle of water, to protect the ring.
1), the nitrogen tube is from the upper to the lower part of the furnace round around the circle in the circle labeled Φ3mm number of holes only.
2), cooling fan: the outside of the furnace body for a cooling for the outside of the fan, when the process requires rapid cooling, press the control cabinet button, cold wind along the lining of the inner wall of the tangential spiral to bring out the heat.
3, temperature control
(1), the main heating circuit using PID triac SCR zero trigger control, through the use of Shanghai Guolong intelligent instrument for reasonable programming and parameter settings, can reach the best temperature control, can calculate the furnace's best PID Parameters, to achieve a more stable temperature uniformity.
(2), heating the implementation of components using two-way SCR zero-crossing trigger.
(3), over-temperature limit alarm function.
(4), furnace temperature recording using a circular chart recorder to complete the process of recording.
