Production method of carbon

Abstract

The invention discloses a production method of carbon, and relates to the improvement of a technique for a carbon material production process. The production method comprises the following steps of: calcinating, crushing and screening, material batching and blending in a raw material storage bay, material conveying implemented by using an integrated screw conveyor, kneading, molding and roasting. The production method is characterized in that (1) a heating device is added on the outer wall of the raw material storage bay for material batching and blending, and used for carrying out heating and heat preservation on material batching and blending; (2) a heating device is arranged on the outer wall of the integrated screw conveyor for material conveying, and used for carrying out heating and heat preservation on material batching and blending. According to the production method of carbon disclosed by the invention, aiming at the problem that in the existing production of carbon products, the preheating temperature of dry materials is too low, and the kneading effect is not ideal, the heating device is added on the outside of the raw material storage bay or the integrated screw conveyor so as to raise the temperature of dry materials in the raw material storage bay or the integrated screw conveyor, in such a way, the temperature of dry materials meets technological requirements, the occurrence of a phenomenon that a paste material is kneaded non-uniformly is eliminated, and a situation that the production of carbon products is stable and the quality of carbon products reaches the standard is ensured.

Description

technical field [0001] The invention discloses a production method of carbon, which relates to the improvement of a process method in the production process of carbon materials. Background technique [0002] Carbon products such as electrodes for steelmaking and cathode and anode carbon blocks for aluminum electrolysis have a long production cycle and many production processes. Their common processes include calcination, crushing and screening, batching, kneading, molding and roasting. As long as there is a problem in one of the links, it will cause harm to the quality of the final product, and there will be unqualified carbon blocks. [0003] During the kneading process of the paste in the carbon plant, the preheating temperature of the dry material is generally too low. This phenomenon is particularly prominent in the anode carbon block production line for aluminum electrolysis. The maximum temperature of the dry material using the preheating spiral continuous kneading p...

Problems solved by technology

If the preheating temperature of the dry material is too low, the temperature difference between the dry material and the asphalt during the wet mixing process will cause the temperature of the liquid asphalt to drop rapidly, the viscosity will increase, and the wettability of the dry material will become poor, which will lead to poor kneading. Uniformity often causes quality problems such as dry material, pitting, and cracks in the green body
