Manneng Electric Equipment Co.,LTD (used to called Suzhou Jiuwei Electric Furnace Equipment Co., Ltd.) has a special opinion on the strong industrial group of Suzhou Annealing Furnace
Suzhou furnace annealing furnace to be filled with nitrogen and hydrogen care gas, in order to reduce the amount of gas, requiring the furnace and the transmission parts sealed, but the general size of the Suzhou annealing furnace (about 48 meters long, about 22 meters high), welding Sewn more, flange interface is complex, so in order to be completely sealed is not possible. The appropriate parts around it should be equipped with a cooling fan, used to introduce the external cold air into the hood, the hot air out of the hood. It is very important to have a constant burning process. Production practice confirmed that the strip tension mpa can meet the needs of the same strip. Wires and terminals should be threaded, crimped or adjoining. And the practice confirmed that the blast furnace temperature can guarantee nof section of the non-oxidizing air, as far as possible to avoid secondary oxidation of strip, is conducive to rth stage to restore the dye.
The basic point of the ladder logic in the programmable controller is to determine the exhaust gates and the suction in accordance with the temperature of # 1, # 5 and # 8 The opening of the damper to control the reverse air flow. 3 heating system design. The first lower baffle 2 in the compartment 30 within the sector in addition to the skeleton (the first under the enhanced plate. The use of coke oven gas, blast furnace gas when the temperature fluctuations in gas will be larger, will also cause fluctuations in the excess coefficient of air. In the case of oxygen, the annealing process takes place. The oxide layer will be removed in the subsequent on-line pickling process to produce a net and no oxide layer ..3 × 1n · mmmt state is semi-hard 8o / Hard. × 1mm tensile strength pulp annealing temperature 9on · m / copper softening annealing soft oa half of the rise and lower: state ~ 9mp; hard copper room temperature dry air almost no oxidation when ma hard ~ 8mp.
The basic point of the ladder logic in the programmable controller is to determine the exhaust gates and the suction in accordance with the temperature of # 1, # 5 and # 8 The opening of the damper to control the reverse air flow. The lining joints shall be offset from each other by at least mm. Mainly used in mechanical parts, silicon steel, copper, copper, wire and other non-oxidative light annealing. In addition the moment of the oven is also the furnace is longer than the muffle furnace. In the system, the n-type nickel-chromium-silicon-nickel-silicon thermocouple sensor is used in the system. The temperature is 200 ℃ 1300 ℃. It has the advantages of good linearity and good thermoelectricity, high stability and good resistance to oxidation. system. If the temperature of # 4 and # 5 is still above the upper limit, the relative amount of reverse air flow should be continued to return excess heat (reduce the heat absorbed by the # 1 section from the electric heating element).
Galvanized Suzhou annealing furnace thermal diagnosis of heat balance method to accurately measure the thermal efficiency of Suzhou annealing furnace conditions, and then furnace pressure diagnosis, furnace gas dew point diagnosis, no oxidation of the heating zone diagnosis, radiation heating zone diagnosis , The heat dissipation diagnosis of the furnace table, the diagnosis of the cooling section, the diagnosis of the furnace temperature and the plate temperature, and so on, so as to find out the fundamental reason for the thermal efficiency. Figure 6 for example, when the nozzle spacing mm nozzle to the strip of the distance is mm through the actual jet cooling test measurement and theoretical calculation to obtain steel strip in the case of the nozzle, The amount of stock can be calculated by the formula.
This is the most basic, the most convenient diagnostic items, but the main pressure is often not being people face, in fact, to ensure the normal operation of the furnace, the first must ensure that the furnace pressure is normal and constant, galvanized Suzhou Annealing furnace furnace pressure control 5 ~ 7pa more appropriate, should pay attention to is only section detection to reflect the problem. 6w / cm long life design.
