The installation of the electric heating tube is very important. Its function is the same as the human heart. If we want this heart to work for a long time, we must understand it correctly and prevent it from being damaged by operating errors. Therefore, we have always believed that the installation of the electric heating tube needs to follow certain steps and follow the correct operation steps to make the electric heating tube work for a long time. How to do it?
BORIS 008613456528940 JINBAO HEATING PRODUCTS FACTORY for everyone to sort out the basic requirements for installation of electric heating pipes as follows:
1. Ensure that the furnace temperature is evenly distributed. In large medium-temperature furnaces and high-temperature furnaces where radiation heat transfer is the mainstay, in addition to installing components on the furnace wall and bottom, it is best to install electric heating pipes on the furnace roof and furnace door. At the same time, more electric heating tubes should be installed in places where the furnace heat loss is large, near the furnace door hole, and near the outlet of the vibrating bottom furnace. When the height of the furnace is very short, the electric heating pipes are often arranged on the bottom and top of the furnace.
2. There are three installation methods for the corrugated type, spiral type and the corrugated type of the wire-shaped electric heating tube. In terms of service life, the wire-shaped corrugated type is the best, the ribbon-shaped corrugated type is the second, and the wire-shaped The spiral is the worst. The corrugated wire-shaped electric heating tube has the best heat exchange conditions. Even if the surface load is larger, the service life is longer, so it can save electric heating tube materials and maintenance man-hours.
3. Minimize the radiation shielding between the electric heating tubes and between the supporting bricks on the furnace wall. The installation position of the electric heating tube should be such that the heat can be easily transferred to the workpiece without overheating the workpiece locally.
4. High-aluminum products should be selected for the support of the electric heating tube of the medium-temperature furnace. The high-temperature furnace with the furnace temperature above 1000°C should be made of relatively pure alumina products, and the low-temperature furnace can be made of general clay products. The iron oxide content in refractory products should be small, and asbestos, slag wool, water glass, etc. should not be in contact with the electric heating tube. Because of the fusible eutectic formed between these and the electric heating tube, the element will be burned, and the oxide film layer of the electric heating tube can be destroyed, and the electric heating tube will be damaged due to accelerated oxidation.
The installation of industrial electric heating pipes in the equipment may be far more than that. How electric heating pipes can work better for a long time, we are willing to explore together. This will not only promote the improvement of our producers, but also improve the quality of products to satisfy the ultimate beneficiaries.
