High conductivity Cold ramming paste of steel rod
- Brand: ZHONGXING
- Type: High conductivity Cold ramming paste of steel rod
The cold ramming paste produced by ZhongXing carbon is a paste specially developed for the cathode carbon block of aluminum reduction cell, which is used to fill the large gap around the cathode, the gap between the carbon and connect the cathode steel rod and the cathode carbon block. This kind of paste has good heat shrinkability in the process of baking. The linear shrinkage is less than 0.15%. In the process of cathode construction, the temperature window is very wide, which can adapt to the environmental temperature of 17-42 ℃. During the construction, the carbon block does not need to be heated or sprayed with binder, so the construction process is simple and the construction quality is easy to guarantee.
