In foreign history, Archimedes, the ancient Greek philosopher, invented a kind of screw pump, using the continuous rotation of the screw, the use of liquid spiral form from one sealing cavity pressure to another sealing cavity, and finally extrusion pump body. This screw pump is the prototype of today's screw conveyor.
Wire drawing and annealing process will be used when the mesh of high temperature mesh belt is processed in the wire drawing plant. The mesh of high temperature mesh belt should be treated by two times of wire drawing and two times of annealing, which is referred to as "two drawing and two retreating" for short. The treated mesh with two extraction and two withdrawal has better linear stability, better flatness of the spiral, better flatness of the high-temperature mesh belt, and longer theoretical life of the high-temperature mesh belt.
After the chain conveyor is installed, in order to fully develop its characteristics during operation and application, some corresponding work needs to be done.
The chain conveyor can withstand relatively large loads and long-distance transportation. The whole line is parallel and curved. The width of the chain can be designed according to customer needs or specific development conditions. The chain plate mode is parallel line chain plate and curved chain plate.
Generally speaking, ordinary stainless steel mesh belts are thermally brittle when operating at high temperatures, and stainless steel mesh belts are also the same. The heat generated by the stainless steel mesh belt due to friction during operation. Due to the difference in the thermal expansion coefficient of the stainless steel mesh belt caused by the different manufacturing process, when different materials are welded together, there is a possibility of thermal fatigue.
