Today is the eleventh day of the first lunar month. I believe that most of my friends have already been engaged in work. Yinuo sees that many friends have a lot of small problems with the use of the steel rolling furnace at work after the holiday. Let's answer questions together.

Some netizens asked, the refractory temperature of the hanging bricks of the heating furnace, under normal circumstances, the long-term use temperature is about 1350 degrees Celsius. The temperature of the heat exchanger of the steel rolling heating furnace mainly depends on the flue gas temperature and the thermal efficiency of the heat exchanger. At present, the preheating air temperature of the heating furnace ranges from 350°C to 600°C.

Friends who want to delay the stop of the fan of the steel rolling heating furnace need to install a delay relay.

Should the handle valve of the sampling port of the heating furnace gas pipe be removed? If the medium that the valve circulates has no particularity and has no high requirements for use, there is no need for emergency manual conditions. It doesn't matter if there is a handle when in use. To repair or debug the safety valve, the handle needs to be installed.

Some friends are worried that the heating furnace will catch fire and the fire will rush into the pipeline. In fact, there is no need to worry, because there is no air in the pipeline to burn.
