Abstract

The invention provides a micro-tension control system of a copper-pipe high-speed continuous induction annealing furnace, which comprises a pinch mechanism, a speed measurement device, an annealing furnace, a traction tension device and a programmable logic controller, wherein the traction tension device and the speed measurement device are located at the two sides of the furnace chamber of the annealing furnace respectively; the pinch mechanism is located in front of the speed measurement device; and the programmable logic controller is connected with the pinch mechanism, the speed measurement device and the traction tension device respectively. The invention causes the copper pipe to pass through the induction annealing furnace stably and uniformly within the full speed range of continuous induction annealing, without causing stretching deformation, suspension scratch or stacking contraction; and the actually measured annealing speed control precision is less than 1%.

Description

technical field [0001] The invention relates to a micro-tension control system for a high-speed continuous induction annealing furnace for copper tubes, in particular to a micro-tension control system for high-speed continuous induction annealing furnaces for copper tubes used for bright annealing of finished products of high-precision copper coils and air-conditioning internal thread copper tubes and tube blanks control. Background technique [0002] During the processing of internally threaded copper tubes, in order to ensure precise forming quality, strict requirements are put forward for the annealed grain size and mechanical properties of copper tubes before forming. The traditional roller bottom coil annealing process has poor grain size consistency of the inner and outer layers of the coil, making it difficult to guarantee the quality of high-precision internal thread forming, and two rewinding processes are required before and after internal thread forming. The proce...
