Embodiment Construction

[0015] A molding process for a bottom-slotted cathode carbon block for an aluminum electrolytic cell is characterized in that the process is that the cathode carbon block is first vibrated and pre-grooved to form a raw block, after roasting, and finally processed by slotting and milling.

[0016] The grooves are partial or through single or multiple grooves.

[0017] The grooves are opened on the surface and inside of the carbon material.

[0018] The cross-section of the groove is regular or irregular.

[0019] The cross section of the groove is polygonal or circular.

[0020] Referring to the finished carbon block drawing, according to the number and size of carbon block grooves, correspondingly transform the vibration forming machine weight platen: fixedly install the corresponding steel rod or use other materials or devices that meet the process requirements, and form the raw block after vibration forming The surface forms corresponding grooves.

[0021] The size requi...

Abstract

The invention relates to a forming process in production of a carbon material, and particularly relates to a forming process for a cathode carbon block with a bottom groove for an aluminum electrolytic cell. The forming process is characterized by comprising the steps of: vibrating and pre-slotting the cathode carbon block to shape and generate a block; roasting; and finally, machining a grooved milling face. The forming process provided by the invention is special; the cost is reduced; and the carbon block yield is improved.

Description

technical field [0001] The invention relates to a forming process for producing carbon materials, in particular to a forming process for a bottom-grooved cathode carbon block for an aluminum electrolytic cell. Background technique [0002] The production of cathode carbon blocks for electrolytic aluminum must go through batching, kneading and molding processes. The raw carbon blocks produced are roasted and graphitized. After the process, it becomes a finished block. [0003] In the past, the cathode carbon block produced by vibration molding has not undergone pre-grooving molding treatment, and the cathode carbon block is processed and grooved after roasting. This molding method feeds more materials, the actual yield is lower, and the cost is higher. At present, there is no molding process using pre-grooving. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a molding process of a bottom...
