What are the key things to look for when using a graphitising furnace?

The use of graphitising furnace need to pay attention to the following key matters.

1, furnace temperature control: the core function of the graphitising furnace is to carry out high-temperature treatment of substances, so the control of the furnace temperature is a key issue that requires special attention when using. Ensure that the furnace temperature can reach the required processing temperature, and can be stabilised within the set range. Excessively high or low temperatures may result in unsatisfactory treatment of the substance or even damage to the graphite tube inside the furnace. Before use, according to the characteristics and requirements of the substance to be treated, set the appropriate temperature control parameters, and check the accuracy of the temperature sensor in the furnace.

2, safe operation: the use of graphitising furnace involves high temperature, high pressure and other dangerous factors, so safe operation is crucial. In the use of the process should wear personal protective equipment, such as fire gloves, fireproof clothing, etc., in order to prevent scalding accidents caused by the high temperature inside the furnace. In addition, to ensure that the substances and gases in the furnace are stable and harmless, and to prevent foreign objects from entering the furnace.

3, ventilation and exhaust: graphitising furnace will produce a large amount of smoke and exhaust gas when processing substances at high temperature. These exhaust gases may contain toxic gases and particles. Therefore, in the use of graphitization furnace, must do a good job of ventilation and exhaust, will be discharged after effective treatment of exhaust gases, in order to ensure the health and safety of operators.

4, cleaning and maintenance: use graphitising furnace after a period of time, the furnace will remain a certain amount of powder, soot and other impurities. These residues will affect the accuracy of the temperature sensor inside the furnace, but also reduce the heat transfer efficiency of the furnace. Therefore, the graphitising furnace needs to be cleaned and maintained regularly to ensure its normal operation and service life.

5, reasonable operating methods: when using the graphitising furnace, it must be operated in accordance with the correct operating methods. Firstly, understand the instruction manual, familiar with the operation steps and precautions. Secondly, according to the characteristics and requirements of the material, reasonably select the appropriate processing parameters, such as temperature, time and so on. At the same time, pay attention to the use of graphitization furnace limitations to avoid overloading and beyond its specified operating range.

6, the handling and placement of the sample in the furnace: pay attention to the reasonable placement and handling of the sample in the graphitising furnace. The placement of the sample location and method will directly affect the furnace temperature uniformity and processing results. Therefore, it is necessary to choose suitable sample containers and sample handling methods to ensure that the samples can be fully exposed to the high temperature environment in the furnace. At the same time, in the operation process should be careful to avoid excessive accumulation of samples, so as not to produce too much smoke and exhaust.

7, accidents and emergency treatment: In the process of using graphitising furnace, some accidents or abnormalities may occur. Such as temperature control failure, furnace tube rupture, power supply failure and so on. For these accidents, the operator should be professionally trained to master the necessary first aid measures and emergency treatment. Before using the graphitising furnace, a perfect emergency plan and training system should be established, and equipped with appropriate first aid equipment and fire fighting equipment to cope with all kinds of accidents that may occur.

In conclusion, the use of high-temperature graphitising furnace needs to pay special attention to the furnace temperature control, safe operation, ventilation and exhaust, cleaning and maintenance, reasonable operating methods, handling and placement of samples in the furnace, accidents and emergency treatment and other key matters. Only under the premise of reasonable implementation of these matters, to ensure the normal operation of the high temperature graphitising furnace and the use of the effect, to ensure the safety of the operator, and to obtain satisfactory results.
