Device and method for preventing copper wires from being oxidized in production of enameled wires

Abstract

The invention provides a device and a method for preventing copper wires from being oxidized in the production of enameled wires. The device comprises an annealing furnace and an annealing pipe penetrating the annealing furnace; wherein, a water tank is arranged at the outlet end of the copper wires of the annealing pipe; and the device is provided with one or more annealing pipes which are arranged in a tilted manner. The copper wires penetrate the water tank containing de-ionized water right from the annealing pipes of the annealing furnace, the temperature of the copper wires is equivalent to that of the annealing furnace, so that steam can be automatically generated when the copper wires are in contact with the de-ionized water; and the steam enters the annealing furnace via the annealing pipe, thereby preventing the copper wires from being oxidized and ensuring that the vapor entering the annealing pipes is continuous, stable and sufficient. The enameled copper wires produced by the invention have the advantages of bright surface and stable voltage performance, improves the quality and reduces the reject rate; as the steam generation device using the waste heat of exhaust gas is not used, and the de-ionized water used for cooling and rinsing is also used for sealing the annealing pipes on the outer wall of the annealing furnace at the same time, the invention greatly simplifies the production equipment of enameled wires, reduces the cost of installation and maintenance and ensures the safe operation, energy conservation and environmental protection.

Description

technical field [0001] The invention relates to a device and a method for preventing oxidation of copper wires in the production of enameled wires. Background technique [0002] Steam is needed to prevent the oxidation of bare copper wire during annealing in the production of enameled wire. Therefore, the steam generator is an indispensable auxiliary equipment for the production of enameled copper wire. The generation of steam requires heat, and the usual heating method is to use a simple electric heating tube for heating, but it consumes a lot of electricity, so the production cost is very high. In the existing enameled wire production, most of the required steam is obtained by steam generating devices. [0003] Chinese Patent Document No. CN2519883 disclosed on November 6, 2002 a steam generator utilizing the waste heat of waste gas, which is used for anti-oxidation equipment during copper wire annealing in the enameled wire production process. It mainly connects the lin...
