Description
Technical field
The invention belongs to fire resisting material field, relate in particular to a kind of acid and alkali-resistance wear-resisting anti-thermal shock flint clay brick and manufacture method thereof.
Background technology
On the new type nonaqueous cement kiln, decomposing furnace is one of parts of its most critical, and the refractory materials that use at these positions must have resistance to acids and bases, wear resistance and thermal shock resistance preferably.These positions are the anti-peeling high aluminium brick or the high alumina castable of normal use.This position atmosphere soda acid atmosphere height of decomposing furnace, flow velocity height, ash concentration height, serious wear are particularly because washing away of high speed Dual-Phrase Distribution of Gas olid causes these position wearing and tearing very serious.
Summary of the invention
In order to overcome above-mentioned deficiency, technical problem to be solved provides a kind of wear-resisting anti-thermal shock flint clay of acid and alkali-resistance brick that is applicable to that new type nonaqueous cement kiln decomposing furnace position is used just in the present invention.
The technical problem that the present invention also will solve provides the manufacture method of the wear-resisting anti-thermal shock flint clay of above-mentioned acid and alkali-resistance brick.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is as follows:
The wear-resisting anti-thermal shock flint clay of a kind of acid and alkali-resistance brick, it comprises the component of following parts by weight:
5～15 parts in 3 ~ 5mm flint clay aggregate
30～40 parts in 1～3mm flint clay aggregate
10～20 parts in 0 ~ lmm flint clay aggregate
15 ~ 25 parts of flint clay fine powders
5 ~ 10 parts of silicon nitride fine powders
5～7 parts of zirconium mullite fine powders
No. 3 mud l～3, Suzhou part
8 ~ 10 parts of combined binders
4～6 parts in water.
Wherein, described flint clay fine powder is 220 orders.
Wherein, described silicon nitride fine powder, zirconium mullite fine powder are 320 orders.
Wherein, described combined binder is Al
2O
3, SiO
2Press the mixture of 7:3 mass ratio.
Make the method for above-mentioned flint clay brick, comprise the steps:
1, with flint clay aggregate, flint clay fine powder, silicon nitride fine powder, the zirconium mullite fine powder of three kinds of specifications of formula ratio, Suzhou No. 3 mud, combined binder and water are mixing to evenly;
2, the material that mixes is through friction press compression moulding, work in-process unit weight 2.10 ~ 2.30 gcm
-3
3, the adobe of moulding is through 60 ~ 90 ℃ of bakings 12 ~ 24 hours, base substrate residual water-content≤2% after toasting;
4,1350 ℃ of following roastings 3 ~ 4 hours.
Flint clay brick of the present invention has the performance of acid-fast alkali-proof, owing to there is mullite to generate in the matrix, and added zirconium mullite also can be toughness reinforcing and improve thermal shock resistance, the silicon nitride hardness that adds is very big, wear resistance is very high, and flint clay brick of the present invention has good resistance to acids and bases ability and washes away and thermal shock resistance.
Acid and alkali-resistance,Wear-resisting, anti-thermal shock flint clay brick, because the kind of bond material is different with add-on, its performance (the soft beginning temperature of lotus, the anti-folding/ultimate compression strength of normal temperature, wear resistance, anti-thermal shock stability) is also different, and the adding of combined binder is necessary to the goods low-temperature sintering, ZrO
2The transformation toughening effect can improve the performance of material really, flint clay particle that goods are selected for use and Al cheaply
2O
3-ZrO
2-SiO
2Matrix has good corrosion resistance, and abrasion resistance and thermal shock resistance have use value widely.
Beneficial effect: the wear-resisting anti-thermal shock flint clay of acid and alkali-resistance of the present invention brick has higher intensity, refractoriness and wear-resisting, thermal shock resistance.Be applicable to cement kiln decomposing furnace and other Thermal Equipment.Its on decomposing furnace, show have acid and alkali-resistance, wash away, good thermal shock, line change little, characteristics such as antistripping, long service life.Manufacturing process of the present invention is simple, is easy to realize.
