사용시주의 사항 laboratory muffle furnaces

1. When the high-temperature muffle furnace is used for a long time or is used again after a long period of inactivity, it must be oven-baked. The oven time should be four hours at room temperature 200°C. 200°C to 600°C for four hours. When in use, the furnace temperature should not exceed the rated temperature, so as not to burn the heating element. It is forbidden to pour various liquids and easily soluble metals into the furnace. The muffle furnace works at a temperature below 50°C. At this time, the furnace wire has a longer life.

2. The muffle furnace and controller must work in a place where the relative humidity does not exceed 85%, and there is no conductive dust, explosive gas or corrosive gas. When metal materials with grease or the like need to be heated, a large amount of volatile gas will affect and corrode the surface of the electric heating element, causing it to be destroyed and shorten the life. Therefore, the heating should be prevented in time and the container should be sealed or properly opened to remove it.

3. 머플로 컨트롤러는 0-40℃의 주변 온도 범위 내에서 사용을 제한해야 합니다.

4. According to the technical requirements, regularly check whether the wiring of the electric furnace and the controller is in good condition, whether the pointer of the indicator is stuck or stagnated when moving, and use the potentiometer to calibrate the meter due to magnetic steel, demagnetization, wire expansion, and shrapnel Increased error caused by fatigue, balance failure, etc.

5. 재킷의 파열을 방지하기 위해 고온에서 갑자기 열전대를 빼지 마십시오.

6. 퍼니스 챔버를 깨끗하게 유지하고 제 시간에 퍼니스의 산화물을 제거하십시오.
