Application and production composition of continuous annealing furnace:

Purpose: it is used for continuous bright annealing of copper straight pipe (bar), steel pipe, aluminum pipe or coil of different specifications in controlled atmosphere.

Features: workpiece continuous through preheating, heating, heat preservation, slow cooling, cooling, no length limit. The transmission adopts roller type synchronous transmission, frequency control, stable and reliable. Through the protective atmosphere and strong thermal atmosphere circulation, the temperature is uniform, and the inner and outer surfaces are very bright. Special design of cooling zone (independent research and design of Suzhou jinruier electric furnace) ensures uniform cooling of workpieces. The inner and outer surface of the treated product is bright with high quality and productivity. Heating mode: electricity.

Annealing process and principle of continuous annealing furnace:

Continuous annealing furnace is mainly used for hypereutectoid carbon steel and alloy tool steel (such as steel used for cutting tools, measuring tools and dies). Its main purpose is to reduce the hardness, improve the machinability, and prepare for later quenching. This process is beneficial to plastic processing and cutting processing, and also improves mechanical toughness. Especially for bearing steel, tool steel and other steel, if spheroidizing annealing is carried out before quenching, the following effects can be obtained: Bearing Steel: uniform quenching effect; reducing quenching deformation; improving quenching hardness;

How to raise the temperature of continuous annealing furnace:

Continuous annealing furnace is a kind of furnace used for heat treatment, which can be used to process metal. Changing the process can get the material properties you want, such as reducing the hardness of the material properly, which is convenient for later processing.

1. After closing the air switch in the control cabinet, turn on the power button on the cabinet,

2. After that, the power button switches of zone 1, zone 2 and zone 3 will be turned on respectively.

3. Set the temperature controller at 200 ℃ for 6 hours, then set it at 500 ℃ for 4 hours, and then set it at 800 ℃ for 2 hours, then it can be used
