A Manufacturing Method of Copper Row Annealing Device

Annealing process is a method of heat treatment of metal materials by slowly heating the metal material to the required temperature to ensure sufficient time, followed by water cooling at a suitable rate (generally slow water cooling, sometimes water cooling by manipulation). Copper bar quenching can make copper bar obtain ideal strength, ductility and drilling characteristics. At present, the processing technology includes air oxidation quenching, shaft furnace quenching and bell furnace quenching. Air oxidation quenching is gradually being replaced because of its outdated processing technology, energy consumption, air pollution, raw material consumption and product quality can not be guaranteed. The annealing process of shaft furnace belongs to braising in storage tank, and there is no warm air circulation system. In bell furnace quenching, the centrifugal fan with strong convection circulation system is usually installed at the bottom of the hearth. During the whole quenching process, nitrogen gas is continuously filled into the hearth and exhaust pipe is outward together.

But at present, due to the limitation of equipment structure, there are problems such as insufficient water cooling time, single quenching and low productivity. There are still different levels of air oxidation in surface layer after quenching in the factory of Zhongda Drawing Return Device. The comprehensive type can not be repaired enough, and it is impossible to consider full automatic continuous production. Requirement.

In order to deal with the technical deficiencies of background drawings, the patents of the invention select and give technical specifications. The copper platen quenching equipment includes load plate, support frame, connecting ear, driven roller, active roller, drive motor, conveyor belt, greenhouse, first water cooling chamber and second water cooling chamber. The bottom end of the load plate is described above. There are four support frames, one set of front and rear symmetrical connecting ears on each side of the load plate. The driven rollers and active rollers are installed on the connecting ears. The conveyor belt is installed on the driven rollers and active rollers. The upper surface of the load plate is successively provided with greenhouse, first water cooling chamber, second water cooling chamber and drive from right to left. Actuator motor, driver motor and active roller are connected according to triangular belt. The greenhouse, the first water cooling chamber and the second water cooling chamber are respectively provided with greenhouse cover, the first water cooling chamber cover and the second water cooling chamber cover. The first vapor distributor, the second vapor distributor and the last vapor distributor are installed inside. The steam distributor is equipped with heating wires inside the greenhouse.
