Bell bright annealing furnace works

The bell-type bright annealing furnace by the heating hood cover, cooling cover, inside cover, stove, vacuum system and electrical control system. The furnace is mainly for strip and wire coiled bright annealing and tempering high production efficiency, less pollution, easy operation and maintenance and so on.
Work piece placed in a protective atmosphere filled with the protective hood uniform heating and cooling. Strong and protective atmosphere circulating fan can work after annealing to obtain a uniform surface hardness and luster, the vacuum system for protective gas and air replacement, the safe and reliable operation. Hood can be equipped with multiple hearth furnace, continuous operation, and its work processes generally: furnace installed - I vacuum - through protective gas - heating - heat - gas, water combined cooling - vacuum cleaners - deflated - baked - next workflow.
1. Vacuum cleaning system can be completely avoided mixing with air, hydrogen, hydrogen atmosphere for high fully applicable, and with plenty of protective gas than simply reduce the cost of cleaning the muffle furnace, the furnace atmosphere to accelerate the transition time. 2. Temperature uniformity is good, the furnace temperature can be controlled within the workpiece within ± 5 ℃, each part to be treated consistent with good mechanical properties.
3. Fan and stove, stove connection with the inner cover parts used PPM level airtight sealed structure for the safe use of the atmosphere to create the conditions to be treated without removal, adhesion phenomena, and to meet carbon steel, alloy steel, etc. bright annealed material.
4. Use of strong convection blower, vacuum cleaning, gas, water and other new technologies combined cooling, can speed up the process cycle, increase productivity, the main performance indicators have reached the level of similar foreign products.
5. Cooling system with a shunt (axis wind turbine structure) as compared to gas, water cooling can accelerate the combination of cooling the workpiece, to simplify the device structure, reducing construction costs and ease of maintenance.
6. Can automatically complete heating, insulation and other processes, temperature SCR power microcomputer intelligent control, programmable logic controller can be used to achieve full operation of automatic process control and automatic recording.
7. With over-temperature alarm, explosion relief, cooling water pressure loss alarm, emergency gas supply and other safety devices, safety and reliability.
