Tube furnace is an indispensable mechanical equipment in metallurgy, abrasive tools and other industries. It has very excellent performance, accelerates the progress of staff work, and also promotes the development of these industries. In order to better use the equipment, we should follow the following instructions during operation:
(1) Place the furnace tube symmetrically in the center of the furnace, place the sample in the center of the furnace tube, place the tube plugs at both ends of the furnace, and assemble them in the order of the inner flange sleeve, sealing ring, pressure ring, sealing ring and outer flange sleeve. Tighten three hexagon screws evenly in turns in multiple times to ensure that the flange is not skewed;
(2) When opening the gas circuit of the tubular furnace, it shall be opened in the order of the main valve of the gas cylinder, the pressure dividing valve and the pipeline switch. When closing, it shall be closed in the opposite direction;
(3) Connect the gas path according to the sequence of air inlet pipe, air inlet valve, air outlet valve and safety bottle, and adjust the gas flow rate through the air inlet valve and gas path switch. Generally, one bubble is continuously bubbled in the safety bottle;
(4) Turn on the air switch, turn on the power key, enter the program temperature setting, press the heating key to start working;
(5) After the procedure is completed, the ventilation can be stopped after the furnace temperature is naturally cooled to below 100 ℃, and the furnace can be opened to take out materials.
The use of the tubular furnace is a very important content. Using the equipment according to the correct process can effectively improve the efficiency of the equipment and avoid the failure of the equipment in use. Therefore, we should carefully read the instructions before using the equipment and operate the equipment according to the above contents.
