The maintenance and use of the blast furnace tuyere is an important part of ensuring the normal operation of the blast furnace and extending its service life. Here are some maintenance and usage considerations:

Maintenance precautions:

1. Regular inspection: Regularly check whether the bricks, linings, cooling equipment, etc. of the tuyere are damaged, cracked or worn, and repair or replace them in time.

2. Clean the dust: Regularly clean the dust from the tuyere to avoid excessive dust from clogging the tuyere and affecting the normal ventilation of the blast furnace.

3. Prevent falling off: Strengthen the fixation of the bricks on the heating surface of the tuyere to prevent the bricks from falling off and affecting the normal operation of the blast furnace.

4. Keep the cooling equipment unobstructed: Ensure that the cooling equipment (such as water cooling pipes) at the tuyere is unobstructed to ensure the cooling effect.

Precautions for use:

1. Control the temperature: Reasonably control the temperature of the blast furnace to avoid over-temperature ablation of the tuyere and cause damage.

2. Control wind speed: By adjusting the opening and wind speed of the tuyere, ensure the air pressure balance inside and outside the blast furnace to avoid damage to the tuyere bricks caused by excessive local wind speed.

3. Control the gas composition: Strictly control the gas composition in the blast furnace to avoid corrosive substances on the tuyere, cooling equipment, etc., which will accelerate wear and damage.

In addition, paying attention to safety is an important aspect of using and maintaining blast furnace tuyere. Operators must receive professional training, operate in strict accordance with operating procedures, and wear personal protective equipment to avoid injuries caused by operating errors or accidents.
