Abstract
The invention discloses an enhanced consumption reduction graphite tube. The enhanced consumption reduction graphite tube comprises, by weight, 60-70 parts of graphite powder, 15-20 parts of asphalt, 10-15 parts of fire clay, 5-8 parts of borax, 3-5 parts of activated bentonite, 2-4 parts of epsom salt and 3-5 parts of boric acid. A making method of the graphite tube comprises the steps of (1) the raw material pretreatment, (2) burdening forming, (3) roasting and (4) dipping. An antioxidant is added to the graphite product, so a dense and solid porcelain protection layer is formed at a high temperature, and an oxidation reaction of oxygen and graphite is prevented, thereby the effective service time of graphite and graphite-containing products is prolonged, and synergism and consumption reduction effects are reduced. The graphite tube made in the invention has no bubble, crack or burst problems, and has good work performances and work life.
Description
technical field:
The present invention relates to a kind of enhancing consumption reduction carbon tube.
background technology:
Graphite is because refractoriness can reach more than 3500 DEG C, and acid and alkali alkali corrodes beautiful being widely used in metallurgical refractory product again simultaneously.The graphite combined with charcoal and graphite-containing product, at high temperature unique shortcoming is not resistance to oxidation, and for overcoming ancient cooking vessel processed not sludge proof disadvantage, numerous producer studies in various degree and develops various antioxidant to solve this needs.Add aluminium powder in goods, silica flour can play eight certain anti-oxidative effect.How to make high temperature lower carbonaceous article surface contacted with air not oxidated, and then extend the duration of service of goods, reduce the cost of user, increase the economic benefit of product, receive special concern.
Before this, some producer, at the surface spraying fire-resistant coating of continuous casting three-major-items, plays certain beautifying and decorating effect, but can not stop the oxidizing reaction of oxygen and graphite, result is that in using, the top layer of goods is constantly oxidized, constantly comes off, and greatly reduces the work-ing life of goods.
Existing carbon tube, exist bubble, easily crack, the problem such as explosion, serviceability, working life are all undesirable.It is long how to produce a kind of life-span, and the carbon tube of favorable working performance is the technical problem to be solved in the present invention.
summary of the invention:
The present invention is in order to overcome the problems of the prior art, and provide a kind of and strengthen consumption reduction carbon tube, it is characterized in that, each component is composed as follows according to weight part:
Graphite Powder 99 60-70 part;
Pitch 15-20 part;
Refractory mortar 10-15 part;
Borax 5-8 part;
Activated bentonite 3-5 part;
Epsom salts 2-4 part;
Boric acid 3-5 part.
This carbon tube making method comprises the steps:
(1) raw materials pretreatment: add water refractory mortar, borax, Epsom salts, boric acid 80-200% stirring at normal temperature 50-80min;
(2) forming ingredient: after Graphite Powder 99, pitch and said mixture being mixed, put into forming mould extrusion molding;
(3) roasting: formed pipe is put into stoving oven set temperature 130-150 DEG C, reaction 30-35min, is warming up to 1130-1170 DEG C, and reaction 3-5min, is cooled to rapidly 700-750 DEG C.；
(4) flood: the formed pipe through calcination process is dried further, puts into resol and flood, then heat-treat, obtain finished product;
Above-mentioned one strengthens consumption reduction carbon tube, and it is characterized in that, raw material forms whole granularity >=180 order, and its medium pitch adopts mid-temperature pitch.
Above-mentioned one strengthens consumption reduction carbon tube, it is characterized in that, in described step (4), drying and processing temperature is 150-160 DEG C, and the drying and processing time is 22-26 hour; The dip treating time is 8-9 hour; Heat treated temperature is 150-160 DEG C, and heat treatment time is 12-15 hour.The beneficial effect of the invention:
Antioxidant adds in graphite product by the present invention, can form the close solid porcelain protective layer of matter, prevent the oxidizing reaction of oxygen and graphite in high temperature.And then the effective storage life of graphite and graphite-containing product can be extended, play the effect of synergy consumption reduction.There is not the problems such as foaming, crackle, explosion in the carbon tube that the present invention obtains, achieves good serviceability and working life.
