Do you know what to consider about the use of microwave high temperature muffle furnace?

- Feb 20, 2019-

Microwave high temperature muffle furnace is one of the general heat treatment laboratory equipment for laboratory analysis, industrial and mining enterprises, elemental analysis and scientific research units, quenching, annealing, tempering and other small steel parts. High temperature furnaces can also be used to sinter metals and ceramics. Dissolution, analysis and other high temperature heating.


1. When using the muffle furnace after initial use or long-term deactivation, the oven should be used first. The oven should be kept at room temperature 200 ° C for 4 hours and at 200 ° C to 600 ° C for 3 hours. When using, the furnace temperature must not exceed the rated temperature to avoid the occurrence of burning electric heating elements. The furnace is filled with various liquids and readily soluble metals. It is recommended that the muffle be operated below 50 °C to maintain a long service life.


2. The muffle control function should be limited to the ambient temperature range of 0-40 °C.


3. The muffle furnace and control function work under the condition that the relative temperature does not exceed 85% and there is no conductive dust, explosive gas or corrosive gas. When it is desired to heat a metal material such as grease, a large amount of volatile gas will affect and corrode the surface of the electric heating element, resulting in shortened or destroyed service life. Therefore, when heating, it should be prevented and sealed or properly opened and removed in time.


4. Hot spots should not be pulled out suddenly at high temperatures to prevent the jacket from bursting.


5. According to the technical requirements, it is necessary to regularly check whether the electric furnace wiring and control functions are good, whether the indicator hand is stuck, and the potentiometer is used to check the fatigue level. Magnetic steel, demagnetization, wire and shrapnel. The error caused by balance damage or the like increases.


6. After each use, you need to keep the furnace clean, dozens of things to remove the intracranial oxide, to avoid residual effects on the next use.
