Abstract
The invention discloses a carbon protection ring, which is prepared by using waste anode carbon blocks, coal, graphite and asphalt as raw materials, wherein the waste anode carbon blocks account for 40-50% by weight, anthracite 10-20% by weight, graphite powder 20-30% by weight and coal pitch 10-15% by weight, and the waste anode carbon blocks are formed by compression molding after being mixed and heated. The invention has the advantages of low production cost, good product quality, reduced environmental pollution and the like. Because the waste anode carbon block is adopted with larger specific gravity, the production cost is greatly reduced, and the mechanical strength and the oxidation resistance are greatly improved. In addition, the waste anode carbon block can be fully utilized, the pollution to the environment is reduced, and the problem of treating the waste anode carbon block is solved.
Description
Technical field:
The present invention relates to the carbon protective ring that a kind of Aluminum Electrolysis Production is used.
Technical background:
Anode block is connected as a single entity with the steel pawl and inserts in the ionogen in Aluminum Electrolysis Production, the part of carbon piece is not used, account for 10～15% of whole carbon piece, this part is scrap anode carbon piece, because it has adsorbed poisonous, the objectionable impurities in the ionogen, so also be a loaded down with trivial details job to its processing.And on the other hand, its physical strength is low, resistance of oxidation is poor owing to the reason of material makes at present used carbon protective ring, and needs through processes such as roastings, and the production cycle is long, the cost height.
Summary of the invention:
The objective of the invention is to: providing a kind of is the method that main raw material is produced carbon protective ring with scrap anode carbon piece, to improve the quality, reduces cost, and utilizes refuse, reduces and pollutes.
The present invention is achieved in that it is is that preparation of raw material forms with scrap anode carbon piece, coal, graphite, pitch, and by weight percentage, scrap anode carbon piece accounts for 40～50%, hard coal 10～20%, Graphite Powder 99 20～30%, coal-tar pitch 10～15%, compression molding after Hybrid Heating.
The present invention compared with prior art, it is low to have a production cost, good product quality, and reduced advantages such as pollution to environment.Since the employing of larger specific gravity scrap anode carbon piece, its production cost is reduced greatly, physical strength and antioxidant property improve greatly, and save sinter process, have shortened the production time.In addition, can make full use of scrap anode carbon piece, reduce pollution, solve the problem of handling scrap anode carbon piece simultaneously again environment.
Embodiment:
Embodiments of the invention: scrap anode carbon piece with 40% and 20% hard coal fragmentation, granularity are less than 4mm, and 30% graphite becomes less than 100 purpose powder with ball mill grinding, and 10% coal-tar pitch fusing back is stand-by; Above-mentioned material was pinched in the pot heated and stirred 25～35 minutes mixing, and temperature is controlled at 120 ℃, and then with material weighing, compression molding promptly gets product.
