Abstract

The invention provides a protective gas energy saving method and system for an online copper pipe machining annealing device. The method comprises the following steps that A, discharging is conducted; B, straightening is conducted, and a workpiece is straightened; C, heating annealing is conducted, during annealing, a nitrogen pipeline is adopted for gas supplying to conduct annealing oxidation preventing protection, a heat exchange area of a gas-water heat exchanger is calculated and determined according to the heating power of the online annealing device, the flow of the protective gas in a heating annealing area and the flow of circulating cooling water in an insulating cooling area, accordingly, an adaptive gas-water heat exchanger is selected, after the nitrogen pipeline serves as a bypass and is connected to the gas-water heat exchanger for heat exchange, water way circulation is conducted through a circulating cooling water tank, and after the gas-water heat exchanger conducts heat exchange and temperature rise, nitrogen is supplied; D, temperature reducing and cooling are conducted, water way circulation is conducted through the circulating cooling water tank, and the workpiece is cooled accordingly; and E, clamping and conveying are conducted, and the workpiece is clamped and conveyed to the next procedure. The energy saving system adopts the above method.

Description

【Technical field】 [0001] The invention relates to an energy-saving method and system for protecting gas of copper tube processing online annealing equipment. 【Background technique】 [0002] In the production process of online annealing equipment for copper tube processing, high-purity nitrogen gas is required as a protective gas for copper tube heating and annealing to prevent oxidation, and circulating cooling water is also used to cool down the copper tube after heating and annealing. The existing method directly transports nitrogen into the heating annealing, and the lower temperature wastes the electric energy of the equipment in the heating annealing zone, which seriously wastes energy and increases the cost of the manufacturing process. [0003] In order to overcome the above-mentioned problems, we have developed a method and system for energy-saving protection gas of copper tube processing online annealing equipment. 【Content of invention】 [0004] The technical pr...
