Cathodic Paste Instruction

A, fried paste procedure:

1, remove all sundries or leftover materials in the pot.

2. Preheat the pan for 30-40 minutes to reach a temperature above 70 degrees Celsius.

3, put the paste into the pot for heating, stirring every 5-10 minutes, so that the paste evenly heated, about 20-35 minutes, so that the temperature of the paste reached 120-140 degrees Celsius.

4, fried paste immediately out of the pot, and paste placed in a storage device with thermal insulation facilities. Cover well with a quilt to keep the batter warm.

B, the paste program:

1, cathode carbon block and cathode steel bar assembly, the cathode carbon block must be preheated. The preheating temperature of carbon block groove is required to be about 100 degrees Celsius, and the dust in the groove is blown clean with compressed air before assembly.

2, the cathode steel rod needs to be derusting, the surface of the silver gray metal luster, and then preheating, the cathode steel rod preheating temperature is about 100 degrees Celsius, and the surface shall not have dust.

3, the wind pressure of the tamping paste is not less than 0.6mpa

4, in the charcoal paste, should first be between the carbon block and the carbon block, and between the carbon block and the trough of all the place blown clean, spray a little coal tar.

5, the gap between the carbon block and the carbon block and the tank is heated, so that the temperature is close to the paste temperature, to ensure that the paste and the carbon block is very good bonding.

6, charcoal paste, generally divided into 4-5 layers of tamping, layer and layer between the thickness should be equal or close, and the solid can not be interrupted, otherwise need to spray some coal tar, in order to ensure a good bond between the paste layer and layer.

7, tie around the paste, generally divided into 3-4 layers for tamping, a tank is generally divided into two times for binding, the interface to reheat and secondary spray coal tar. Make sure the paste is connected at the interface.

8. In the process of solidifying the paste, ensure that the temperature of the paste shall not be less than 100 degrees Celsius, and the temperature difference between the layers of the paste shall not exceed 5 degrees Celsius, and it is strictly prohibited to mix impurities.

Three, paste storage:

1, paste should be stored in a clean and tidy roof warehouse, to prevent exposure to the sun, rain, moisture, extrusion.

2, the remaining paste during the operation, without mixing any impurities, can be used twice, but it is best to use with a new paste (with one).

3. The shelf life of paste is generally 5-8 months under normal storage.
