Abstract
The present invention relates to a kind of shot shape anode mix and method for making thereof, it is characterized in that uniform mixing forms under normal temperature condition, component is few grey carbon material and pitch, also can additional humectant and/or oleic acid tensio-active agent.Compared with prior art, technology is simple, saved a large amount of energy and production utility appliance, production cost is low, and quality reaches the like product national standard, especially suitable as the continuously automatic baked anode anode mix of electrolysis of aluminum, also be applicable to newly-built anode electrolytic cell casting mold.
Description
The invention belongs to the continuously automatic baked anode of electrolysis of aluminum sticks with paste and method for making.
Existing anode mix is thermal source with steam, electricity or organic carrier etc. all, and the calcined petroleum coke particle in fusing coal-tar pitch and the heating kneading machine and the mixture of coal-tar pitch are made through the cooling curing moulding then.Heating temperature is different and different according to pitch softening point, is generally 120-180 ℃.Render in the aluminium cell anode case and do soberberg anode.The production of this kind anode mix not only consumes a large amount of energy, and needs the investment and the maintenance cost of heating and cooling equipment, and is time-consuming, process complexity and cost height.
The object of the present invention is to provide a kind of shot shape anode mix of producing under normal temperature condition, its method is simple and easy, and is with low cost, easy to use, is easy to promote.
The technical essential of production method of the present invention is that the few grey carbon material of powdery is (general≤20mm, granularity is littler to be) and an amount of bituminous cement of granularity≤30mm under normal temperature condition evenly the system of mixing form, in order to improve result of use, also can add an amount of wetting agent (or claiming plastic agent) and/or tensio-active agent, blend together the bulk goods that looses uniformly and use.Have the bituminous cement of 14-37% in this anode mix component,, be preferably coal-tar pitch, granularity≤20mm as coal-tar pitch and/or petroleum pitch etc.Surplus for few grey carbon material, as refinery coke and/or pitch coke etc., be preferably refinery coke.Preferably add 0.8-6.3% wetting agent and/or 0.2-3.3% oleic acid tensio-active agent again, wetting agent such as carbolineum, coal tar, washing oil, creosote wet goods can add wherein one or more.The purpose that adds wetting agent (or plastic agent) is moisteningly preferably to lack grey carbon material, and can reduce pitch softening point and surface tension thereof, has improved the adhewsive action of binder pitch to few grey carbon material thus.Adding the oleic purpose of tensio-active agent is further to reduce asphalt surface tension force, when pitch in the shot shape anode mix is heated on anode electrolytic cell, can moistening well few grey carbon material particle, and have certain mechanical strength to guarantee this anode mix.
Because the present invention can be formed by directly mixing under normal temperature condition, therefore compared with prior art, its method is simple, saves the energy and many heating cooling apparatuss, and is with low cost, be easy to promote.And quality can reach the like product national standard.The complementary goods that anode electrolytic cell after shot shape anode mix is not only applicable to start consumes also is applicable to newly-built anode electrolytic cell casting mold.Need equally during casting mold this product heating is made it certain plasticity, with the compactness that guarantees that its overall integrity contacts with anode bar.
Present invention is described below in conjunction with embodiment, but not as limitation of the invention.
Adopt anode mix conventional formulation batching: refinery coke-4～+ the 2mm grade accounts for the 20%(weight ratio)-2～+ the 1mm grade accounts for the 15%-0.15mm powder and accounts for 48%, surplus is-1～+ the 0.15mm grade, refinery coke accounts for 73% of weight, coal pitch of agglomerant (94 ℃ of softening temperatures) accounts for 27% of total amount, granularity≤30mm, carbolineum adds total amount 3%, and oleic acid adds 1.2%, mixes 50 minutes in the Z-shaped twin shaft kneading machine of normal temperature intermittent type 400 liters.Its quality product has reached the like product national standard.Can satisfy self-baking aluminium electrolytic bath fully by the electrolytic trial proof and produce needs.
See the following form.
As seen from the above table: shot shape anode mix electrolysis is placed in the middle, and other every performances all can be stuck with paste with conventional anode and be matched in excellence or beauty, and its production system utility appliance is few, save the energy, per 1000 tons of anode mix fuel saving coal 350-410 tons, cost of goods manifactured is low, produces normally stable.
