As the core equipment of steel smelting, the steelmaking blast furnace needs to pay close attention to a series of issues during installation and debugging to ensure that the equipment can operate normally and smelt efficiently. The following are the issues that need to be noted during the installation and commissioning of steelmaking blast furnaces:

Blast furnace foundation and foundation: The foundation and construction of the blast furnace must meet the design requirements and ensure load-bearing capacity and stability. During the debugging process, it is necessary to check whether the foundation and foundation have been damaged and repair them in a timely manner.

Installation of blast furnce body: When installing the blast furnace body, appropriate lifting equipment and safety measures need to be used. During the process, attention should be paid to avoiding collision and damage to the blast furnace body. It is strictly prohibited to cut, weld, or perform operations that directly affect the performance of the equipment during the installation of the blast furnace body, to ensure the integrity of the blast furnace body.

Equipment connection and wiring: During the installation and debugging process of the blast furnace, it is necessary to inspect and adjust the connection and wiring between the blast furnace body and other equipment. Connecting pipelines, valves, instruments, etc., requires correct installation to ensure no leaks or blockages.

Cooling system installation: A stable cooling system is required for the blast furnace during the smelting process. The cooling system includes cooling water pipelines, water pumps, water tanks, and cooling equipment. During the installation process, it is necessary to ensure that the system can operate normally, and the installation position of the water pump and the connection of the pipeline must meet the design requirements.

Air preheating system installation: The combustion system of the blast furnace requires an air preheating system to improve combustion efficiency. The air preheating system includes an air preheating furnace, fans, pipelines, and control equipment. During the installation process, it is necessary to ensure that the system is firmly connected, the fan operates normally, and reasonable insulation protection is carried out.

Installation of blast furnace gas system: The gas produced by blast furnace smelting needs to be recycled or treated. The gas system includes gas pipelines, dust removal equipment, purification equipment, etc. During the installation process, attention should be paid to the connection and sealing of gas pipelines, as well as the normal operation and cleaning of purification equipment.

Installation of blast furnace lining: The blast furnace lining is an important component of protecting the inner wall of the blast furnace and improving smelting efficiency. During the installation process, attention should be paid to the flatness and correct positioning of the furnace lining to avoid cracking and detachment.

Instrument equipment installation: The operation of the blast furnace requires a large number of instrument equipment for monitoring and control. During the installation and debugging process, it is necessary to ensure that the instrument equipment is installed correctly and wired correctly to ensure the normal operation and safety of the blast furnace.

Wire, cable, and grounding issues: During the installation and commissioning process of the blast furnace, attention should be paid to the connection and grounding of the electrical system to ensure its reliability and safety. Check if the wires and cables are connected correctly, and if the grounding resistance meets the requirements.

Lubrication and maintenance system: Lubrication and maintenance of blast furnace equipment are crucial for the normal operation of the equipment. During the installation and debugging process, it is necessary to check the installation and pipelines of the lubrication and maintenance system to ensure that the system can supply lubricants and maintenance equipment normally.

In short, the installation and commissioning of steelmaking blast furnaces is an important link to ensure the normal operation of equipment and efficient smelting. During the installation and debugging process, attention should be paid to the above issues to ensure the stability, safety, and efficiency of the equipment. At the same time, it is necessary to strictly follow the design requirements and construction specifications for operation, follow construction safety measures, and ensure the safety of workers.
