Description
Technical field
The present invention relates to a kind of unshape refractory, especially a kind of kiln vehicle surface castable.
Background technology
At present, in heat treatment industry, need heavier Large Steel baslled iron body is placed directly on kiln vehicle surface, then
Kiln car pushes in heat-treatment furnace, after treating that the workpiece heat time arrives, then forges before the workpiece of high temperature is transported to forging machine.With
The heavy refractory material kiln car work top of high temperature absorption surface not only to bear weigh several tons or tens of tons of high temperature workpiece,
Also want the reaction that can resist high-temperature steel baslled iron body with refractory material.Require that work top is at high temperature wanted at 1100 to 1400 DEG C
There is preferable creep resistance, thermal shock resistance, high wearability, it is often more important that the opposing iron scale erosion to work top
Destroy reaction.In the prior art, general employing high alumina castable and mullite castable carry out pouring into a mould work top.
Although using both castables can meet certain high temperature requirement to a certain extent, but can not preferably resist iron scale
Infiltration corrode, application property is poor, and wearability is poor, and creep resistance is poor, and globality is poor, and during use, table top produces big
The crackle of amount, service life is extremely short, up to three or four months.The normal use of heating furnace kiln car, frequent dimension are had a strong impact on
Repair, affect product quality, increase energy resource consumption.
Summary of the invention
For the defect during overcoming existing High-Alumina and mullite castable to use, the present invention provides one to have
Antioxidation iron sheet corrodes, fire-resistant, wear-resisting and abrasion resistance is high, and creep resistance is preferable, and workability is preferable, can be greatly prolonged kiln
The castable refractory in ride face service life.
The present invention solves above-mentioned technical problem and be the technical scheme is that a kind of work top castable, by following heavy
Amount weighbf component composition: synthesis strontium aluminate 3-8, NiFe_2O_4 spinel 5-10, leave alabaster 20-35, synthesizes corundum 5-10, just
Beautiful 30-40, synthesizes magnesium zircon sand 10-15, sub-high soil 5-15, nano-calcium carbonate nickel 3-5, aluminous cement 3-8；Additional dispersant 0.1-
0.2, levelling agent 0.1.
Further, described NiFe_2O_4 spinel is positive NiFe_2O_4 spinel.
Further, the weight content of described leave alabaster is more than 98%.
Further, described sub-high native mainly comprising as highly active anhydrous aluminium silicate and zirconium nitride, weight both it
Amount ratio is 90:10.
Further, described dispersant is REFPAC®288, its true specific gravity is 2.60-2.70 gram every cubic centimetre, heap
Long-pending density 1.15-1.30 gram every cubic centimetre, Exemplary chemical composition is (percentage by weight): aluminium oxide 62-64%, SiO2＜
1.0%。
Further, the weight content of described nano-calcium carbonate nickel is more than 99%.
Further, the weight content of described synthesis magnesium zircon sand is more than 99%.
Further, the weight content of described synthesis corundum is more than 99%, and remaining impurity is mainly silicon dioxide.
Further, described levelling agent is polyether siloxane copolymer.
The preparation method of a kind of work top castable, comprises the following steps: in above-mentioned parts by weight ratio stirring mixing
Uniformly, then add appropriate clean water during onsite application, be stirred with forced stirrer, when meeting construction requirement, stirring
The castable mixed is put into inside the mould of work top, carries out vibrations with vibrating head and constructs.
Compared with the material of existing use, the invention has the beneficial effects as follows: 1, work top castable of the present invention has
Higher elevated temperature strength, can undertake the weight of heating steel billet；The infiltration that can resist iron scale under high temperature is corroded, and improves
Wearability, extends body of heater service life 2-3 times.2, castable good thermal shock of the present invention, not shrinkage cracking, globality
Good, it is effectively protected the globality safety of work top.3, the present invention can in use step-reaction, sub-high soil and
Aluminous cement has effect of plural gel, can suppress the alkalinization on castable surface simultaneously；Strontium aluminate, synthesizes Buddha's warrior attendant
Sand, NiFe_2O_4 spinel, the material such as nano-calcium carbonate nickel is miscellaneous to entering into the steel billet iron sheet inside the fire-resistant liner body of work top in using
Matter can play purification, substantially increases the high temperature overall performance of workbench castable；Due to the fact that and add efficiently
Dispersant REFPAC®288, the rational grain size distribution of pyrophyllite and whole scheme obtains good the watering of a kind of workability
Material feeding, solves the defect that current castable application property is bad.By the enforcement of whole technical scheme, improve current production and deposit
Deficiency, preferably meet the needs of current production, it is achieved that the technical purpose of the present invention.
