Abstract
The invention relates to a pouring iron brick with high aluminum and low iron, comprising the following components by weight percent: 30-50% of bauxite chamotte with a diameter of 1-3mm, 10-20% of bauxite chamotte with a diameter of 0-1mm and 35-55% of bauxite chamotte with a diameter of 0.074 mm and clay mixed powder. The preparation method of the pouring iron brick with high aluminum and low iron comprises the following steps: a. selecting and grading raw material; b. grinding and processing raw material; c. blending the obtained processed bauxite chamotte particles; d. shaping green bricks;e. drying green bricks; f. sending the dried green bricks in a tunnel kiln to sinter at 1320-1350 DEG C; g. taking out the finished products, inspecting and warehousing. The preparation method of theinvention reduces the sintering temperature of the pouring iron brick with high aluminum and low iron so as to save the energy and reduce the production cost of bricks.
Description
Technical field
The invention belongs to a kind of refractory materials, be specifically related to a kind of pouring iron brick with high aluminum and low iron and preparation method thereof.
Background technology
Pouring iron brick with high aluminum and low iron is widely used in now and waters in the steel, but because Al
2O
3Requiring of content is different, so the content of the high aluminium bauxite clinker of selecting for use is all different, especially temperature is generally more than 1420 ℃ during tunnel kiln sintering, because this temperature height, so waste energy, the brick cost height that sintering goes out.
Summary of the invention
Technical problem to be solved by this invention provides a kind of pouring iron brick with high aluminum and low iron and preparation method thereof, and its sintering temperature in tunnel furnace is low, and temperature is 1320～1350 ℃, thereby can reduce the cost of brick, save energy.
Technical scheme of the present invention: a kind of pouring iron brick with high aluminum and low iron, its component and weight content are as follows:
The high aluminium bauxite clinker granule content of 1～3mm is 30～50%,
The high aluminium bauxite clinker granule content of 0～1mm is 10～20%,
0.074mm high aluminium bauxite clinker and clay mixing fine powders content be 35～55%.
A kind of preparation method of pouring iron brick with high aluminum and low iron, its step is as follows: a, raw material selection classification; B, grinding and processing raw material; The particle high aluminium bauxite clinker of c, processing is mixed; D, green brick forming; E, brick bat drying; Tunnel kiln sintering is gone in f, dried adobe, and sintering temperature is 1320～1350 ℃; Inspection after construction warehouse-in behind g, the kiln discharge.
The present invention compared with prior art has following beneficial effect: the present invention selects local high aluminium bauxite clinker for use, and cost is low; Feed composition is few, the content uniqueness, and especially sintering temperature is reduced to 1320～1350 ℃ by 1420 ℃ of routine in tunnel furnace, thereby has saved the energy, has reduced the cost of pouring iron brick with high aluminum and low iron, has brought bigger profit to enterprise.
