Yinuo has seen many netizens who don’t understand the use of steel rolling heating furnace in one way or another. Let’s take a look at the problems encountered during the operation of steel rolling heating furnace!

Operation Guide for Steel Rolling Heating Furnace

1. The steel rolling heating furnace cannot burn up to the temperature

The main reasons for this problem are: the burner power cannot be reached, the output has increased too much, the air-fuel ratio is unreasonable, and the thermocouple temperature measurement is not accurate.

2. The method of introducing fuel gas when the steel rolling heating furnace is started

①Introduction of nitrogen to replace fuel gas system, pay attention to every dead corner;

②Sampling and analyzing the oxygen content of the fuel gas system (O2＜0.5% is qualified)

③Close the hand valve in front of the furnace and use the pressure control valve in front of the furnace

3. Smoke from the high chimney of the steel rolling heating furnace

The cause of this problem is incomplete combustion, and it is necessary to adjust the air valve of the burner or the fuel supply pressure

4. Maintenance items for steel rolling heating furnace

The electrical equipment, water cooling system, etc. should be inspected each time before starting the furnace to ensure that the equipment is in good condition before starting the furnace. Equipment should be cleaned regularly, and flammable and explosive materials should not be stacked. Equipment failure should be repaired in time.
