Intermediate frequency furnace is an indispensable processing equipment for metallurgical professions. Many smoke and dust will occur during exercise, feeding and tapping, and the most amount of smoke and dust will be generated during exercise. According to the processing and production process of the intermediate frequency furnace, it is an economical, reasonable and good purification method to select the intermediate frequency furnace dust removal equipment to suck the rotary hood and capture hood to process the smoke generated during the exercise of the intermediate frequency furnace. The structure and working principle are as follows:
1: Structure of dust removal equipment of intermediate frequency furnace
Structure and working principle of intermediate frequency furnace dust removal equipment The bag dust collector of the intermediate frequency furnace is composed of a shell, a filter bag, an ash hopper, an ash discharge device, a support and a pulse ash cleaning system. After the dust-laden gas enters the intermediate frequency furnace dust removal equipment from the air inlet, it will first encounter the inclined partition in the center of the air inlet. The coarse particle dust in the gas directly falls into the ash hopper, which plays the role of pre-dust collection. The airflow entering the ash hopper then folds upward, passes through a filter bag with a metal frame inside, and the dust is captured on the outside of the filter bag. The purified gas enters the clean room on the upper part of the filter bag room and finally gathers into the air outlet discharge.

。 The intermediate frequency furnace dust collector is economical and practical, with a simple shape, simple device, convenient repair and low investment cost . 120 摄氏度左右，除尘效果可达 99% ，如有特别用处 的还可以提供耐温，耐腐蚀滤袋的除尘器。 It is mainly used for dust collection at small dusting points. The machine uses polyester cloth bags, the inlet temperature is about 120 degrees Celsius, and the dust removal effect can reach 99% . If there is a special use , a temperature-resistant and corrosion-resistant filter bag can be provided.
。 The intermediate frequency furnace flue gas capture system consists of a low-position mobile dust collection hood, feeding equipment, tapping equipment and dust removal equipment . The low-position mobile dust cover completely covers the operation channels and tapping pits, so that the production process of the intermediate frequency furnace is fully performed in the low-position mobile dust cover, which completes the useful capture of the entire process of smoke. ; 出钢时，中频炉渠道翻转直接出到出钢轨迹平车上的钢包里，出钢进程在烟罩内完结，战胜了部分集尘罩出钢时烟气部分外漏的状况。 When feeding, the material is fed through the feeding equipment, and the material is filled up several times according to the production requirements, which solves the problem of difficult capture of flue gas during the feeding of the vehicle. In the ladle, the tapping process was completed in the hood, which overcomes the situation that some of the flue gas leaked out when some of the dust collecting hoods were tapping.
中频炉除尘器的运转特色 3 Operating characteristics of IF furnace dust collector
The air inlet of the dust removal equipment of the intermediate frequency furnace is set on the ash hopper. After the gas enters the ash hopper, it mainly touches the baffle at the end of the duct. The effect is the same as the principle described above. Each dust collecting room is cleaned in turn according to the given time distance. Each dust collecting room is equipped with a raising valve, which is closed during dust cleaning, and the filtering airflow passing through the dust collecting room is blocked. The valve is open, spraying water, oil and high pressure clean air into the filter bag to remove the dust on the outside of the filter bag. The pulse blowing width and dust cleaning cycle of each dust collection room are successively performed by a dedicated dust cleaning degree controller.
4: Structure and working principle of IF furnace dust removal equipment
The heavy metal components in the soot during the melting process of the intermediate frequency furnace are related to the composition of the steel type and the steel operation process. Because the appearance of scrap steel is often modified with paint or galvanized, the vapor pressure of zinc and lead is higher at high temperatures, it is easy to oxidize and evaporate during the melting process, and the concentration is higher in dust collection ash. 2 ～ 4% ，镍和铬的蒸气压很低，集尘灰中的镍和铬首要来自熔融气体夹藏的金属及其氧化物 ( 炉渣 ) 的极细微粒颗粒。 The affinity of nickel and chromium with oxygen is small, the oxidation loss of chromium is about 2 to 4% , the vapor pressure of nickel and chromium is very low, and the nickel and chromium in the dust collection ash mainly come from the metal and Very fine particles of its oxide ( slag ) . 2 ～ 6% ，镍的含量约 0.7 ～ 0.9% 。 The chromium content in the stainless steel dust ash is 2 to 6% , and the nickel content is about 0.7 to 0.9% .
