Magnesite ramming mass at the bottom of the electric furnace is made of synthetic high-iron and high-calcium sand, high-purity magnesia sand and some additives. The dry and rammed material at the bottom of the electric furnace is dry material, so it is easy to construct at the work site and can be used after the construction is completed. No baking required, dry tamping mass greatly improves efficiency and extends service life. Advantages: Dry ramming blocks have good corrosion and impact resistance, as well as thermal shock resistance at high temperatures.
1. Low bulk density and low thermal conductivity.
2. High mechanical strength.
3. Good thermal shock resistance.
4. Small linear changes and no cracking.
5. Resistant to erosion and wear.
6. It has good volume stability under the following conditions: high temperature.
7. Easy to operate: save time and effort.
