Blackening and treatment of heating tube

Blackening and treatment of heating tube

Blackening treatment is sometimes used in the production process of electric heating tubes. Heat treatment is a process of heat treatment of metal objects such as stainless steel. After treatment, there will be an oxide film on the surface to achieve the purpose of corrosion and rust prevention. After the heating treatment, the wear resistance of the heating tube surface and the hardness of the surface will be improved, and the parts inside the heating tube will not be affected.

What is the power range of the heating tube?

The voltage of the heating tube is 220-240V, and the power of the heating work is 690-750W. This is a durable electric heating tube with a higher voltage. The heating power of the low input voltage is relatively small, and the high input voltage is used. The output power is large. The maximum operating voltage cannot exceed 240V and the maximum output power is 750W. When the voltage is 220V, the power of the heating tube is 690W. In the case of normal voltage use, the output power of the heating tube is 690W.

Brazing of various metal products, welding of various knife blades, saw teeth, welding of steel pipes, copper pipes, welding of the same kind of dissimilar metals;

It has a wide range of performance, and has a very important application in anti-bao- or ordinary occasions, thus creating extremely convenient living conditions for people. It is particularly unusual in terms of comprehensive thermodynamic performance. Yes, it can satisfy modern people's specific pursuit of quality products and make people's lives better. The ceramic heating ring has low heat loss and high thermal power level, which can reach more than 90%; the preheating time required by the screw extruder can be reduced from the original 2 to 2.5 hours to about 40 minutes, and the production power level is greatly increased. In addition, the raw material cost of the quartz tube heating ring is low and the weight is light.
