tubular furnace of installation technique

Tips to be paid attention to during installation and use of tubular furnace

Tubular furnace USES: widely used in the experimental and production of refractories, electronics, ceramics, metallurgy, machinery, building materials, special materials, new materials development, fluorescent materials and other fields.

Matters needing attention during the use of tubular furnace

1. Once you find a problem, shut off the power supply immediately.

2. The instrument should be placed in the air flow place, insist on furnace cleaning.

3. The thermocouple is not easy to pull out under high temperature to prevent the outer casing from bursting.

4. If the electric furnace is of vacuum sealing structure, inflammable and explosive gas cannot be passed in.

5. Check the safety of electricity before use, and check all targets before starting the operation.

6. Do not leak the high temperature solution to the bottom of the furnace, so as to avoid the use of backing plate or aluminum oxide powder barrier.

7. During the experiment, protective measures such as gloves and masks should be taken to avoid inhaling harmful evaporating gases in high temperature.

8 electric furnace in the use of a period of time, the furnace will appear fine cracks, are normal appearance, this appearance will not affect the experimental production, can be used to repair aluminum oxide coating.

Installation and Operation skills of tubular electric furnace:

1. The tubular electric furnace needs no special installation and only needs to be placed flat on the indoor floor or on the platform. The controller shall be placed on the working table, the tilt of the working table shall not exceed 5 degrees, and the small distance of the controller from the furnace shall not be less than 0.5 meters.

2. The load capacity of the power cord, switch and fuse connected with the controller and the furnace shall be slightly greater than the rated power of the furnace.

3. When wiring, first loosen the screws on the left and right sides of the controller housing, then turn the housing upside down and connect the power cord. The connection line between the controller and the furnace and the thermocouple connection line. Insert the thermocouple into the furnace from the hole in the thermocouple fixing seat, plug the gap between the hole and the thermoelectricity with asbestos rope, and fix it.

After 4. Check the wiring and correct electricity, first close the power switch, then the controller panel on the toggle switch to the open position, adjust the Settings button, set the temperature to you need degree, a red light, also have the contactor and sound absorption, tubular electric furnace electricity, ammeter indicates the heating current value, temperature in furnace temperature and slowly rising, that work.

5. In order to check whether the protection device is working normally, the method is: loosen one end of the thermocouple, at this time the temperature indicator rises rapidly to a higher point and automatically cuts off the heating power, then the device is in good condition, after reconnecting the thermocouple, it can work normally.
