The invention discloses application of clay clinker flint clay to replace high bauxite chamotte in composite sliding nozzle brick outer layer materials, wherein the composite sliding nozzle brick outer layer materials comprise the following raw materials in percentage by weight: 60-70% of flint clay aggregate, 20-30% of bauxite chamotte powder, 5-10% of soft clay and 4-6% of binding agent aluminum dihydrogen phosphate. According to the invention, the flint clay is used as aggregate to replace high bauxite chamotte aggregate to be used on the composite sliding nozzle brick outer layer material, so that the use requirement can be met, and the production cost of the product is effectively reduced.
Description
Technical Field
The invention belongs to the technical field of sliding nozzle bricks, and particularly relates to application of clay clinker flint clay on an outer layer material of a composite sliding nozzle brick.
Background
The sliding nozzle brick is a control device for molten steel in the casting process of a continuous casting machine and comprises a sliding plate, an upper nozzle brick and a lower nozzle brick. Because the sliding nozzle brick is contacted with high-temperature molten steel in the steel casting operation process, if the heat resistance is poor, the thermal shock resistance is poor, the compression resistance and the fracture resistance are insufficient, the thermal stress can easily cause the sliding nozzle brick to burst, the molten steel seeps along cracks, and serious accidents such as steel running and the like can be caused.
As a refractory material manufacturer, on the premise of ensuring that the use quality of the product is not reduced, the effective cost reduction is a difficult problem faced by the current enterprises.
The nonrenewable bauxite chamotte is used as a necessary main raw material of the composite sliding gate brick outer layer material, so that the purchasing of the bauxite chamotte is more difficult and the price of the bauxite chamotte is more and more expensive. The market price of 85# high bauxite is already more than 2500 yuan/t.
Therefore, searching for low-cost replacement materials of the bauxite chamotte becomes a technical problem to be solved by the existing refractory manufacturers.
The flint clay is an associated accessory product of coal, and has rich reserve and wide sources on the upper layer of a coal bed.
Flint clay is a generic name of hard clay clinker and is formed by sintering raw flint clay at a high temperature of 1250-1350 ℃. The main mineral of the flint clay is kaolinite, a series of physical and chemical changes occur in the high-temperature sintering process, crystal water, structural water and a small amount of organic matters are released, the volume shrinkage is compact, and finally mullite phase, cristobalite phase and a small amount of glass phase are formed, so that the flint clay has good heat resistance, sintering property and thermal shock resistance.
Impurity content in flint clay, especially Na 2 O+K 2 The lower the O content, the higher the refractoriness. And Al is 2 O 3 /3SiO 2 The closer the ratio is to the theoretical value (a/s=0.85), the higher the purity of the flint clay is indicated. The larger the A/S, the higher the refractoriness of the flint clay, and the wider the sintering melting range. The refractoriness of the high-quality flint clay can reach more than 1750 ℃.
The flint clay has wide market supply source, the price of 1650 yuan/t, which is obviously lower than that of the middle-low grade 85# high bauxite chamotte, and the price difference is about 850 yuan/t.
The flint clay has the characteristics of stable volume, good thermal shock resistance, small water absorption and the like after being calcined at high temperature. The water absorption rate of the flint clay with good sintering degree is less than 5 percent, and the volume density is more than 2.55g/cm 3 。
At present, no related record of using clay clinker flint clay to replace high-aluminum bauxite chamotte for producing the sliding nozzle brick is found in a steelmaking system, and no related literature report of using clay clinker flint clay for producing and applying in composite sliding nozzle brick outer materials is found.

further defined, the composite sliding nozzle brick outer layer material consists of the following raw materials in percentage by weight:
the invention relates to a preparation method of a composite sliding nozzle brick outer layer material, which is characterized by comprising the following specific steps:
step S1, mixing materials, namely respectively weighing raw flint clay aggregate, high bauxite chamotte fine powder, soft clay powder and a binding agent aluminum dihydrogen phosphate solution according to a mixing ratio, firstly putting the flint clay aggregate into a wet mill for uniform mixing, then adding the binding agent for clean mixing for 3-5 minutes, adding the high bauxite chamotte fine powder and the soft clay powder, and uniformly mixing in the wet mill;
s2, ageing the materials, namely adding the evenly-kneaded pug into a special container, ageing the materials for at least 8 hours;
s3, molding, namely adding the trapped pug into a mold to perform composite compression molding;
s4, drying, namely drying the pressed semi-finished product;

s6, grinding, namely placing the semi-finished product sleeved with the hoop on a special grinding machine for grinding;
and S7, coating in batches, namely placing the ground semi-finished product on a tooling platform for surface coating, surface coating and drying.
Compared with the prior art, the invention has the following advantages and beneficial effects:
because flint clay has high refractoriness, has the characteristics of stable volume, good thermal shock resistance, small water absorption rate and the like after high-temperature calcination, and because the prepared composite sliding nozzle brick outer layer material is not in direct contact with molten steel, the composite sliding nozzle brick outer layer material can be used as aggregate to replace high-aluminum bauxite clinker aggregate on the sliding nozzle brick outer layer material, the use requirement can be met, and the production cost of products is effectively reduced.
