The furnace is mainly designed according to customer's bearing steel, copper strip, copper wire, steel strip, coil wire and other non-oxidizing annealing requirements. A heating mantle and two sets of working hearths are used in turn to realize continuous production process. Equipped with a cooling hood to help rapid cooling, the entire production process according to the requirements of the heating process, section heating and insulation, air cooling.
The furnace uses a sealed metal cover (8mm stainless steel 321) to isolate the annealed material from the air. After the vacuum is drawn, it is filled with a protective atmosphere and a safe atmosphere. The annealed material is always in a low dew point and low oxygen and hydrogen during the entire heating and cooling process The mixed gas is protected to ensure that the surface of the workpiece is free from oxidation during heat treatment. Due to the large air volume hot air circulation fan installed in the furnace, the protective atmosphere forms a strong convection cycle, so that the temperature in the furnace is uniform, and the temperature of each point is within ± 5-8 ° C, which can obtain uniform mechanical and physical properties of the annealed material, and has fast heating. The furnace temperature is uniform, the cooling cycle is short, the heat source is fully utilized, energy saving and electricity saving, high efficiency and fast, it is one of the more ideal and applicable annealing treatment equipment.
1. All-fiber structure, good insulation performance of the furnace lining, fast heating, light heating furnace cover, easy displacement, and long service life.
2. The use of iron-chromium alloy with heating elements, good heating performance and easy maintenance.
3. Adopt strong hot air circulation double speed (sealed motor), uniform temperature (± 5-8 ℃), fast heating of the workpiece, shorten heating time, improve work efficiency, save energy, shorten cooling cycle and control each furnace cycle in the shortest time Within, and can guarantee the quality and yield of annealing.
4. Evacuation and refilling with a protective atmosphere can ensure the purity of the atmosphere in the furnace, reduce the amount of gas used, save costs, bright annealing, and no metal loss.
5. The heat-resistant steel inner cover is pressed into a corrugated shape, which increases the heated area and strength, reduces the deformation coefficient, and has a long service life.
6. High-precision imported intelligent meter temperature control, high temperature control accuracy, small temperature difference, with over-temperature alarm, dual control, can ensure that the workpiece is not over-temperature.
7. Each furnace base is equipped with a temperature measuring thermocouple instrument inside the furnace cover, which can keep track of the actual heating temperature of the workpiece in the furnace and the temperature in the furnace during cooling.
