Cold ramming paste has its own precise density, so in this, we can see that the learned knowledge is actually very rich, no matter from what aspect, the characteristics of cold ramming paste is emitted in this, what is the method to determine the height of cold ramming paste?  Xiaobian will explain to you today.

The height of cold ramming paste refers to the height from the top of electrode clip to the top of electrode paste.  If the electrode paste is too high, the thick and fine particles in the cold ramming paste are prone to delamination, or the electrode cylinder is damaged due to too much pressure of the paste column. If the electrode paste column is too low, it is difficult to obtain dense electrode due to too small pressure of the paste column and poor filling.  Cold ramming paste consumes too fast.  Appropriate electrode paste column height is beneficial to improve the quality of electrode roasting and reduce consumption.

Good quality sintered electrode can be obtained by controlling the electrode paste height, which can be controlled by various manufacturers according to the actual situation.  For example, the electrode diameter of 25500kVA calcium carbide furnace is 1250mm, and the height of electrode paste should be controlled at 3.5-4.0m.

Measurement method of cold ramming paste height:

When measuring the height of electrode paste, the tool used is a hemp rope, one end of which is tied with a 100mm*50mm150mm ball made of melted electrode paste. The rope is about 10m, and a mark is made every 200mm.

Is the distance (measured value) from the top of the electrode cylinder to the base of the pressure release cylinder (upper edge of the electrode cylinder coat), mm;  B is the height (measured value) of the electrode barrel empty barrel mm;  C is the electrode paste height (calculated value). Generally, C value is 3500-4000mm.  D is the height of electrode paste liquid, generally D value is 1000-1500mm;  L is the working length of the electrode, about 1800-2000mm from the low ring to the electrode end (L value of the internal combustion furnace is about 1500-1800mm).
