Current monitoring and reforming device for heating pipe of annealing furnace

Abstract

The invention discloses a current monitoring and reforming device for a heating pipe of an annealing furnace, which comprises the heating pipe arranged at the bottom of the annealing furnace, whereinthe heating pipe is connected with a power supply cable; a current monitoring device is arranged on the power supply cable; the current monitoring device is composed of a current mutual inductance module, a transmitter module and a PLC analog quantity input module; the input end of the current mutual inductance module is electrically connected with the power supply cable; the output end of the current mutual inductance module is connected with the input end of the transmitter module; the output end of the transmitter module is connected with the input end of the PLC analog quantity input module; the output end of the PLC analog quantity input module is in communication connection with an operation terminal. According to the current monitoring and reforming device for the heating pipe of the annealing furnace, the fault problem can be found at the first time, the alarm can be fed back, the reliability is good, the response speed is high, the accident incidence rate is reduced, the rateof unqualified products is obviously reduced, and a large amount of cost is saved for enterprises.

Description

technical field [0001] The invention relates to the modification technology of an annealing furnace, in particular to a current monitoring modification device for a heating tube of the annealing furnace, which belongs to the technical field of copper tube processing. Background technique [0002] At present, in the process of manufacturing high-precision copper tubes, annealing copper tubes is one of the most important processes. The so-called annealing is a kind of metal that is slowly heated to a certain temperature, kept for a sufficient time, and then cooled at an appropriate speed. heat treatment process. The purpose is to soften the material after casting, forging and drawing, improve plasticity and toughness, homogenize the chemical composition, remove residual stress, or obtain the expected physical properties. The main factor that annealing affects the hardness of copper tubes is the grain The main factors affecting the grain size are: annealing temperature and hol...
