Embodiment Construction

[0016] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them.

[0017] A high graphitic cathode carbon block production process, comprising the following steps:

[0018] Step 1: choose 100-120 parts by weight of electric forged coal to be crushed to 3-6mm, choose 90-100 parts by weight of artificial graphite to grind, so that the particle size is controlled at 0.3-0.5mm, and dry mix the two to obtain a mixture A;

[0019] Step 2: Take 150-200 parts by weight of asphalt and melt it in a heat-conducting oil furnace to obtain melted asphalt;

[0020] Step 3: Pour mixture A into the kneader, start the kneader, and gradually mix the melted asphalt with mixture A. Working environment: under vacuum environment, atmospheric pressure 1.35-1.45Mpa, temperature 120-140℃, knead for a period of time Finally, carbo...

Abstract

The invention relates to the technical field of cathode carbon block production processes, in particular to a high-graphite cathode carbon block production process. The high-graphite cathode carbon block production process comprises the steps that step 1, material selecting and smashing are performed; step 2, 150-200 parts by weight of bitumen is fetched, the bitumen is melted by a heat conductingoil furnace, and the melted bitumen is obtained; step 3, a mixed material A is poured into a mixing kneading machine, the mixing kneading machine is started, and the melted bitumen is mixed with themixed material A gradually; step 4, a carbon block mixed material C is poured into a vibration molding machine mould, material pouring is performed when vibrating, the atmospheric pressure is 1.3-1.5Mpa, and in a vacuum environment, material pouring is performed when vibrating; step 5, molded carbon blocks are roasted at high temperature, and the roasting temperature is 1250-1400 DEG C; step 6, mechanical machining is performed after cooling. By means of the high-graphite cathode carbon block production process, the produced cathode carbon blocks are low in resistance rate, high in heat conduction rate, large in true density and volume density and low in gas hole ratio, the service life is prolonged, the cost is saved, and use of electrolytic tanks is met.

Description

technical field [0001] The invention relates to the technical field of cathode carbon block production technology, in particular to a high graphite cathode carbon block production process. Background technique [0002] The cathode carbon block is used as the cathode of the aluminum electrolytic cell, and it is built at the bottom of the electrolytic cell, also known as the bottom carbon block. Characteristics The cathode carbon block plays the dual role of conducting electricity and forming the lining of the electrolytic cell. [0003] At present, the cathode carbon block manufactured by the factory has low thermal conductivity, low density, low mechanical strength, and large porosity, which cannot meet the conditions of the electrolytic cell, and the service life is very low, resulting in a waste of resources. Contents of the invention [0004] The object of the present invention is to solve the shortcoming of poor use effect of cathode carbon blocks in the prior art, an...
