Rapid annealing furnace

The rapid annealing furnace uses the iodine tungsten lamp tube as the heating element, and the heating speed is very fast. It adopts the S-type thermocouple to measure the temperature and adopts the international fuzzy PID control. It has high temperature control accuracy <±5℃>. The rapid annealing furnace has The vacuum device can work in a variety of atmospheres.

Introduction to rapid annealing furnace
RTP-1000D4 rapid annealing furnace generally uses iodine tungsten lamp tube as heating element, and the heating speed is extremely fast. It uses S-type thermocouple to measure temperature and adopts international fuzzy PID control, which has high temperature control accuracy. <±5℃>, the rapid annealing furnace has a vacuum device, which can work in a variety of atmospheres. Greatly improve its scope of use. Standard accessories: 1 pair of high temperature gloves, 1 thermocouple, 1 quartz tube, 1 set of vacuum flange. Optional accessories: alumina crucible, quartz crucible, vacuum pump.

1. After the furnace is used or not used for a long time, bake it at about 120℃ for 1 hour, and use it after baking at 300℃ for 2 hours to avoid cracking the furnace. The furnace temperature should not exceed the rated temperature to avoid damage to the heating element and furnace lining. It is forbidden to directly pour various liquids and dissolved metals into the furnace to keep the furnace clean.

2. If the furnace uses a quartz tube, when the temperature is higher than 1000 ℃, the high temperature part of the quartz tube will appear opaque. This is called devitrification (also called devitrification), which is an inherent defect of continuous fused quartz tube and is a normal phenomenon.

3. When using a cold furnace, because the furnace is cold, to be highly endothermic, so the low temperature section easy too fast heating rate, the temperature rise of each period
rate of temperature difference is too difficult, heating rate should be set fully in consideration of the sintered material Physical and chemical properties, so as to avoid spraying and polluting the furnace tube.

4. Regularly check whether the contact of the electrical connection part of the temperature control system is perfect, and pay special attention to whether the connection of each connection point of the heating element is tight.

5. After the furnace has been used for a period of time, if the vacuum is reduced, the temperature-resistant silicone ring between the stainless steel flanges can be replaced or the stainless steel flanges can be reinstalled or the vacuum system can be replaced and repaired to improve the overall vacuum of the system.

6. During the working process of the furnace, if the control deviation cannot be eliminated at around 300℃, the temperature display value does not match the program setting value or the swing is too large. Check whether the parameter "M5, P, t" is set correctly.

7. This furnace is suitable for 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, explosive gas or corrosive gas that can seriously damage metal and insulating materials around the furnace.
