In the production process of the ironmaking process, the moisture content and air temperature of the ironmaking blast furnace blast have a direct impact on the fuel consumption and fuel consumption structure of the ironmaking process. Blast furnace blast dehumidification is to remove the moisture in the blast furnace blast, eliminate the adverse effects of atmospheric humidity fluctuations on the blast furnace forward movement, and create stable operating conditions for the fans.

According to the monitoring of the Iron and Steel Association, at the end of October, the China Steel Price Index (CSPI) was 107.34 points, an increase of 1.24 points or 1.17% from the end of last year; the price of CIOPI imported iron ore during the same period was US6.38/ton, an increase of US.86/ton from the previous month, an increase of 28.57%. The price increase of iron ore is significantly greater than that of steel, and the impact on the production costs of steel companies will gradually become apparent, greatly reducing corporate profitability.
