How to Use Box Muffle Furnace
High temperature box muffle furnace is one of the laboratory equipments used in laboratories, industrial and mining enterprises and scientific research institutes for element analysis and determination as well as heat treatment and heating of small steel parts such as quenching, annealing and tempering. High temperature furnace can also be used for sintering, dissolving and analysis of metals and ceramics.
1. When the muffle oven is used again after the first use or long-term shutdown, the oven must be baked first. The baking time should be four hours at room temperature of 200 and three hours from 200 to 600 respectively. When in use, the furnace temperature shall not exceed the rated temperature in order to avoid burning down the electric heating elements. Statically pouring various liquids and soluble metals into the furnace, the muffle furnace is recommended to work below the maximum temperature of 50 C, so as to maintain a longer service life of the furnace wire.
2. The control function of muffle furnace should be limited to the ambient temperature range of 0-40 C.
3. Muffle furnaces and control functions must be operated in places where the relative temperature does not exceed 85% and there is no conductive dust, explosive gas or corrosive gas. When metal materials such as grease need to be heated, a large number of volatile gases will affect and corrode the surface of electrothermal components, resulting in shortened or destroyed service life. Therefore, when heating, it should be timely prevented and properly sealed containers or appropriate openings should be excluded.
4. Hot spots should not be pulled out suddenly at high temperature to prevent the coat from bursting.
5. According to the technical requirements, it is necessary to check regularly whether the wiring of electric furnace and control function is good or not, whether the pointer of the indicator is stuck and detained when moving, and to check the increase of errors caused by the fatigue of magnets, demagnetization, wire expanding, fragments and balance damage of the instrument with a potentiometer.
6. After each use, it is necessary to keep the furnace clean, remove dozens of intracranial oxides and other things, so as to avoid the residues affecting the next use.
