Naon precautions pikeun operasi tungku muffle

What are the precautions for the operation of the tungku muffle

The muffle furnace can be used for chemical analysis, physical determination and heating of small steel parts in the heat treatment of small steel parts in laboratories of industrial and mining enterprises, scientific research and other units. There are a few points to pay special attention to when using:

When the muffle furnace is used or used again after a long period of inactivity, it is necessary to carry out the oven. The oven should be at room temperature 200°C for four hours. Four hours from 200°C to 600°C. When in use, the furnace temperature must not exceed the extra temperature to avoid burning electric heating elements. Stop pouring various liquids and easily soluble metals into the furnace. The furnace is operated at a temperature below 50 ℃, and the furnace wire has a longer life.

The muffle furnace and controller must be operated in a place where the relative humidity does not exceed 85% and there is no conductive dust. When metal materials with grease or the like need to be heated, a lot of volatile gases will affect and corrode the appearance of the electric heating element, destroying it and shortening its life. Therefore, the heating should be prevented in time and the container should be sealed or properly opened and cleaned.

The muffle furnace controller should be limited to the ambient temperature range of 0-40 ℃. Do not pull out the thermocouple suddenly at high temperature to prevent the jacket from cracking.
