Example Embodiment
[0025] The present invention will be further described below in conjunction with embodiments.
[0026] The following technical solutions are adopted in specific implementation:
[0027] 1. The preparations before opening the furnace are as follows:
[0028] ①The production tools for each position are complete, and the consumable spare parts are sufficient. Sufficient supply of water, electricity, wind, steam, gas, oxygen pipes and oxygen.
[0029] ②According to the calculation of the raw material requirements, prepare enough in terms of variety and quantity to ensure that the raw material cannot be broken after the furnace is opened. In order to open the furnace smoothly, it is required that the filler, coke, ore, flux, etc. have less moisture, powder (less than 5%) and harmful impurities, uniform particle size, and good strength and reducibility.
[0030] ③The equipment inspection and trial operation of each system of the blast furnace. In addition to attaching importance to equipme...
