One, what is fireproof ball: Fireproof ball basically is with industry alumina and kaolin are main raw material, compare via matching reasonably, figuration and fire of high temperature forge become, it has the following distinguishing feature: 1. , mechanical intensity is high, apply cycle to grow; 2. , chemical stability is good, do not produce chemical reaction with stock; 3. , high temperature resistant performance is good, highest heat-resisting temperature can arrive at fireproof ball 1900 degrees.
2, fireproof ball utility: Ball of fireproof accumulation of heat is special apply to fertilizer plant high low temperature to change furnace, in changing furnace of alkylation of chamfer of converter of furnace, hydrogenation, to decoke and armour, lax enrages fluid since, and the support, effect that enclothe and safeguards activator. The hot-blast stove that fireproof ball also can use at steely industry and heat change in equipment. Fireproof ball calls accumulation of heat bulbiform matrix again, bulbiform matrix has thermal shock stability good, accumulation of heat measures big, intensity tall, Yi Qingjie, can repeat use wait for good qualities. The system of combustion of ball of accumulation of heat that applies to gas and furnace of industry of blame gas fuel is chosen.

Fireproof ball
Function: A lot of spherule break up air current very small stream, air current expires in matrix midstream, make intense turbulent flow, broke through matrix surface effectively add facing, because ball way is very small, conduct radius small, thermal resistance small, density tall, thermal conductivity is good, reason can realize burner of type of accumulation of heat again and again and the request of rapid inverting. Matrix can use 20~30 second / the inverting of H, air current of high temperature smoke via matrix bed can fall flue gas to be discharged to 130 ℃ left and right sides inside layer hind. High temperature is gas it is with matrix of classics of empty air current inside same way can warm-up of take leave of arrives to compare flue gas temperature only low 100 ℃ left and right sides, temperature power is as high as 90% above bulbiform matrix is main norms: Φ45mm of of Φ35mm of of Φ30mm of Φ25mm .
Of fireproof ball apply:
1, now
Fireproof ball
applying is to be in a few bigger plants to apply, for example fertilizer plant is glasswork is waited a moment probably. In daily life, also be commonner, say to use a program fireproofly so wider. Often change in fertilizer plant low temperature converter of furnace, changeover furnace, hydrogenation still has the metropolis in desulphurization chamfer and armour alkylation furnace to use its to serve as inattentive gas liquid and sustain the effect that mask and protects activator, the friend that our brief introduction is to hope to understand this respect common sense to wanting about fireproof ball price and utility below can have sure help effect.
2, with other products price of more fireproof ball calculates going up is good in quality and cheap in price, the fireproof ball price that offers on bazaar now is in 891 tons commonly, its product data is Molaishi commonly, can go up via using 1000 degrees of high temperature, a lot of chemical plant can use fireproof ball if because its have,burn a line to shorten again,lead temperature of bate of loading of low, high temperature exothermic of tall, harbour measures tall, anti-corrosive, intensity big, thermal shock brings stability good, heat conduction, it is good fireproof data, and the price on bazaar is not high also, general manufacturer can bear, always welcome for years consequently by bazaar.
3, can saying about the utility of fireproof ball is very extensive, no matter be vitriolic,the converter that still is chemical fertilizer exercise alters probably the metropolis in furnace uses his and the demand according to broad consumer, its still can differentiate to pledge for tall aluminium tall aluminium of fireproof ball, modified pledges fireproof ball, high aluminous high density spends fireproof ball, tall aluminium low Confucianism decay is fireproof ball, its appellation is different, fireproof ball price is different also, want to understand the fireproof ball with more detailed more pertinent information, we can seek advice from manufacturer of relevant and fireproof ball and relevant work staff, general and direct from manufacturer price of wholesale and fireproof ball is met lower.
Excel in is fireproof the introduction of the ball:
1, in fireproof ball hot-blast stove, ask fireproof ball has higher strength commonly, but actually
Fireproof ball
intensity often not quite big, be able to bear or endure because of upside right now of bolide knead hold, bottom is able to bear or endure to bolide is crushed simply or break a circle. Assume fireproof ball crunch became much easy stem sirocco passageway, sirocco does not send blast furnace, if fireproof ball breaks a circle,reduce fully tolerance, increase wind of obstruction, high temperature to send do not go in to affect blast furnace production value next. Consequently demand fireproof product uses a kind of high strength in hot-blast stove bottom.
2, a kind of close tall aluminous qualitative firebrick is with fancy alumina clinker 40~45(granuality is 3.5mm~1.5mm) for aggregate, attend aluminous grog and 45~51 of fine pink makings together, soft clay 7~10 and cyanite pink are matrix pink, 4~5 of oar of adscititious waste paper is bond. The effect when intensity of this firebrick compression is used high at blast furnace lining and hot-blast stove lining is very good, but when be being used at the heat inside hot-blast stove to communicate, accumulate because of its unit appearance big without fireproof ball next talent of accumulation of heat and thermal efficiency all are inferior to fireproof ball.
Have a kind of strength density of tall, bulk the high strenth that talent of big, accumulation of heat crushs by force, not easily is fireproof ball.
3, the Al2O3 that its composition includes fancy tall aluminous aluminous 80%~85% , granuality to be 5μm~8μm exceeds small pink 4%~8% and argillaceous bond 8%~13% , 4%~5%; of oar of adscititious waste paper is fireproof the ball contains Al2O3 70~76% , contain Fe2O3 ＜ 1.5% , still include etc fancy earth of tall aluminous vanadium and the other material; that argillaceous bond contains are fancy earth of tall aluminous vanadium contains Al2O3 85% above, granuality is 3mm~1mm, fireproof ball diameter is 40mm~60mm.
4, because of this fireproof ball includes what granuality is 5μm~8μmm to exceed small pink, its exceeded fine granuality to have the effect that expect is less than, reduced the porosity of fireproof ball greatly, increased the strength of fireproof ball next, compression intensity is as high as 200MPa, it is a convention 2 times of fireproof ball, compare its to express an area with firebrick big, next talent of accumulation of heat strong, thermal efficiency is tall apparent; this external cause is energy-saving effect the surface of the ball is attributed to curved surface structure to increase, aeriform fluidity is gas to avoiding dirt ash jams, and cause broken bits to change had very good effect. It the effect when with its fireproof ball union applies a kind of his low squirm is more apparent. Fireproof ball applies low creep in ball type hot-blast stove fireproof ball applies high strenth of a paragraph of horizontal top upside to be helpful for hot-blast stove accumulation of heat and heat delivering highly in the allocation with 2 paragraphs of reasonable bottom more solved the problem that sticks a ball to be able to be long below effect of high temperature bear hold to.
5, this are fireproof the ball has following interests at having technical ability quite: 1, intensity of fireproof ball compression is high, can amount to 200MPa above, it is a convention 2 times of fireproof ball, crush not easily, ensure sirocco free goes, ensure next blast furnace production value; 2, compare strong thermal efficiency of talent of accumulation of heat with high strenth firebrick tall energy-saving effect is apparent.
Fireproof
Porcelain ball
Fireproof ball is with industry alumina and fireproof kaolin are main raw material, become via scientific recipe, figuration and fire of high temperature forge.
Protect the action of activator. The hot-blast stove that fireproof porcelain ball also can use at steely industry and heat in shift device.
6, fireproof porcelain ball has a character is firebrick be not a patch on, that is mechanical intensity tall, although firebrick also has fight Yi Shejiang to spend tall, but fireproof ball is gotten the better of however in circle of the —— on structural advantage, but can this ask about “ circle to you can be stabilized than the triangle with respect to somebody? ” this is about respecting is fireproof another character of the ball: Chemical stability is good, this character of fireproof ball decided it won't react with other material, make its structure not easy thereby be destroyed, because this is on fireproof data market,ability can have the view with strong also circle.
