Box furnace
The box furnace was translated by English Furnace. According to the characteristics of the box furnace, there are box type resistance furnace, furnace, muffle furnace. Domestic box furnaces and imports are classified according to nationality. According to the heating element, there are: resistance wire muffle furnace, silicon carbon rod, silicon molybdenum rod; according to the rated temperature, the general classification is: 1100 degrees, 1200 degrees, 1400 degrees, 1600 degrees, 1700 degrees furnace, 1800 degrees. According to the controller, there are the following types: pointer table, ordinary digital display table, PID adjustment control table, program control table; according to the insulation material to distinguish: ordinary refractory brick and ceramic fiber. It is a cycle operation type for laboratory, industrial and mining enterprises, scientific research units for elemental analysis and determination, and general small steel parts for quenching, annealing, tempering and other heat treatments. High temperature can also be used for sintering, dissolving and analyzing metals and ceramics. For heating. HEBEI PINGLE FLOUR MACHINERY GROUP CO., LTD , https://www.plrollermill.com
Installation and wiring
1. Open the box and check that the equipment is in good condition.
2. Place the equipment in a place where air circulation, no vibration, no flammable, explosive gas or high dust is selected.
3. Use the working power supply voltage matched with the purchased equipment, and install the air switch that matches the working current of the furnace to connect the grounding protection line reliably. Do not introduce high voltage to avoid damage to the instrument and control circuit. Turn off the power.
4. The test machine should be powered on after installation.
Maintenance precautions
1. After the furnace is used for the first time or after a long time of use, it should be baked at 120 °C for 1 hour and baked at 300 °C for 2 hours to avoid cracking of the furnace. The furnace temperature must not exceed the rated temperature to avoid damage to the heating element and the lining. It is forbidden to directly inject various liquids and dissolve metals into the furnace to keep the furnace clean.
2. When the furnace is used, since the furnace is cold, it needs a large amount of heat absorption, so the heating rate in the low temperature section is not easy to be too fast, and the difference in heating rate of each temperature section is not too large. The temperature of the sintered material should be fully considered when setting the heating rate. Chemical properties, so as to avoid the phenomenon of spraying and pollute the furnace.
3. Regularly check that the contact of the electrical connection part of the temperature control system is good. Pay special attention to whether the connection of each connection point of the heating element is tight.
4. During the working process, if the control deviation is generally not around 200 °C ~ 300 °C, the temperature display value does not match the program given value or the swing is too large, and the setting of the parameter "M5, P, t" is accurate.
5. Applicable to the following working conditions:
(1) The ambient temperature is between -10 and 75 °C.
(2) The relative humidity of the surrounding environment does not exceed 85%.
(3) There is no conductive dust around the furnace, explosive gases and corrosive gases that seriously damage metals and insulating materials.
(4) No obvious tilt, vibration and bumps.
