[0002] Oriented silicon steel has the characteristics of "orientation", "high silicon" and "low carbon". The production process involves very complex processes such as the selection of micro-alloy additives and inhibitors, the annealing temperature of silicon steel sheets, and the control of atmosphere. The production process is long and technically difficult.

[0003] Decarburization is one of the processes in the production process of cold-rolled oriented silicon steel. Its main purpose is to complete the primary recrystallization so that there are a sufficient number of (110)

[001] primary grains in the matrix; to remove carbon from the steel to below 0.003% to ensure that it is in a single α phase during subsequent high-temperature annealing, to develop a complete secondary recrystallization structure, to remove sulfur and nitrogen from the steel, and to eliminate the magnetic aging of the product; and to form a dense and uniform SiO2 film (2 to 3 μm) on the surface of the steel strip. Decarburization needs to be completed in an atmosphere containing water vapor, and the dew point of the atmosphere is also an important factor affecting the decarburization rate. However, the traditional humidifier barrel has the defect of uneven humidification. Therefore, it is necessary to develop a new type of humidifier barrel to solve these problems. Utility Model Content

[0012] After adopting the above technical solution, the utility model has the following positive effects:

[0013] The utility model discloses a humidifier barrel having a partition with through holes, which can divide the barrel body into two chambers. The lower part of the partition is used to store water, and the gas enters the gas chamber through the through holes of the partition after being humidified by the water. The gas chamber on the upper part of the partition is used to store water-containing gas, which can allow the gas to fully contact with water. This can make the output of the water-containing gas more uniform, improve the humidification effect, thereby improving the decarburization stability, and further improving the quality of oriented silicon steel products.
