How can the hot dip galvanizing line effectively achieve energy saving and emission reduction?

Up to now, hot-dip galvanizing line is an essential equipment in hot galvanizing industry. Hot dip galvanizing is the most widely used and effective technological measure in the anticorrosion of steel products. In the process of hot dip galvanizing, how can the hot dip galvanizing line effectively achieve energy saving and emission reduction?

1.Reduce the heat loss of hot dip galvanizing furnace and enhance the heat preservation of the furnace.

Hebei Anno Automation Technology Co., Ltd. recommends that you use refractory brick masonry wall, whole fiber manufacturing furnace wall, refractory brick and avant-garde mixed type furnace wall, or other good insulation refractory materials. This material belongs to thermal expansion type with good thermal insulation performance. The temperature of the outer wall of the furnace is low, and the energy saving effect is good. Its furnace life is long. These measures can effectively reduce the energy consumption of hot-dip galvanizing line.

2.Reducing the exhaust emission temperature of the hot-dip galvanizing furnace

To achieve this goal, you can choose to use a high radiation tube to reduce the heat taken away. You can also use other measures to reduce exhaust gas temperature or increase waste heat utilization. After the hot air is dried, the strip steel, the quenching tank and the strip are passivated. After the gas and water are heated, the temperature will be reduced to below 200 degrees Celsius.

3.Increase the thickness of hot-dip galvanized wall and reduce the shell temperature of the furnace wall.

Increasing the thickness of the furnace wall will increase the input of construction, so you must find a balance between increasing input and obtaining energy saving value.

4.Choose a reasonable heating system

In order to effectively achieve energy saving and emission reduction, heating system is very important. You should choose different temperatures according to different materials to prevent waste of resources, so as to achieve the purpose of energy saving and emission reduction.
