Box type electric furnace (muffle furnace) use precautions

Box type electric furnace (muffle furnace), suitable for analytical research in laboratory or factory, high temperature burning and metal heat treatment, etc. The transistor constant temperature automatic temperature controller or the thermostat controller is used to control the furnace. The internal temperature works .
Since the box type electric furnace (muffle furnace) belongs to high temperature and high heat products, it is necessary to pay attention to life safety and national property safety in daily use. Therefore, Shanghai Kailang Equipment Factory has put forward the "safety*, excellent quality" as the guide. If the operator encounters any problems with this product during the daily operation, all the staff of the factory will serve you.
one.      Place the automatic temperature controller in a stable place , not too close to the electric furnace, so as to prevent the electric furnace heat from affecting the electronic components, remove the short-circuit wire, and then connect the electric furnace to the electric furnace, and then connect the power cable to the AC 220V. And the electric furnace controller is effectively connected to electricity .
two.        Use a wire to connect the thermocouple to the temperature device . Note that ± is not connected correctly . Check if there is an error after the installation .
three.        Connect the temperature regulator to the required temperature, connect the power supply of the control box "input", turn on the power switch, and the green light will turn red when it starts to work.
four.        When the electric furnace is used once or after long-term deactivation, it must be dried by oven:
Oven temperature and time:
200 ° C 1 hour     
400~500°C 1 hour              
600 to 800 ° C for 1 hour
Drying of the oven is a must. The factory has a product in a university's * laboratory, such a thing, a doctor, a direct temperature control of the product to the limit temperature, the reason is very simple, is to see if the products of our factory can meet the standard The high temperature of zui is called, and the first use will cause damage to the experimental samples and products, and artificially cause unnecessary losses, which is very regrettable. Therefore, the factory takes the lead, and hopes that the products of our factory can be used normally in the hands of users, and contribute to the research work of the majority of scientific research workers.
Five, matters needing attention
During installation, all power distribution equipment and instruments have been inspected and adjusted , and the electric furnace and voltage are checked for normality. Is there good contact? The high temperature of the use of zui should not exceed the limit temperature of the series configuration. The object in the furnace must be cut off to ensure the power supply. Safety, electric furnace should be placed in a dry place to protect against moisture, use leakage and cause refractory material to heat up and crack. If the automatic temperature controller needs to exchange places, the console short-circuit line should be connected to avoid damage to the vibrating instrument.
