Difference analysis between dry and wet charging of intermediate frequency furnace charge

The material of the ramming material is a neutral dry ramming material. This furnace lining is a pre-mixed dry ramming material. The high-quality high-temperature binder is selected to have strong crack resistance and high-quality and high-purity quartz sand and quartz powder. With high temperature resistance, it is widely used in continuous operation and intermittent operation in steelmaking. The number of heats above can reach 195 heats. The ZH2 type material is used for smelting gray iron, and the number of heats used can reach more than 300 heats and can reach 550 heats.

According to the construction method, the charge and ramming material of the intermediate frequency furnace can be divided into dry ramming material and wet ramming material. The two main differences are as follows:

1. During the construction of dry batter, high-frequency vibration is used to make the material flow and exhaust, so as to obtain a relatively dense furnace lining; after wet batter is mixed with water, the air gun is used to ram the exhaust to obtain a dense furnace lining.

2. The tire mold will be melted together with the scrap steel in the oven process after the dry batter construction, and the wet batter tire mold can be demolded and used repeatedly.

3. Dry blasting is generally suitable for furnaces with relatively large volumes, and wet blasting is generally suitable for small intermediate frequency furnaces.
