Abstract
Alkaline -resisting brick of effective high performance of cement rotary kiln tertiary air, the internal lining of tertiary air bobbin is piled up into to alkaline -resisting brick, and including circular -arc base member, a plurality of base member splices into complete ring body, and the internal and external surface of base member be the arc surface, and the both sides face that meets with the arc surface is inclined plane in opposite directions, the round hole has been offered to the base member upper surface, and the lower surface corresponds the round hole and has offered cylindric boss, offer the dovetail on surface about having a perfect understanding on the base member side, be equipped with the strip -shaped bump who pegs graft with the dovetail cooperation on the base member another side. It has good thermal -insulated effect, long service life again to have stronger alkaline -resisting erosion.
Description
Technical field
The utility model relates to refractory material and makes field, particularly relates to cement rotary kiln tertiary-air pipe refractory brick.
Background technology
Because new dry process rotary kiln tail gas need be used by pre-heating system and tertiary-air pipe, make heat material burn till hear rate greatly to reduce, but huge pre-heating system and tertiary-air pipe add cooling surface area, radiation loss is increased, therefore use a kind of high-quality wear-resisting, heat insulation material carrys out alternative existing Alkali resistant brick Cheng Liaoge manufacture of cement producer primary goal, and traditional refractory material mostly is high-alumina brick or clay brick, these two kinds of brick have a shortcoming, it is exactly not alkaline erosion, and service life is shorter, when piling up, sealing property is also poor, bonding strength is lower, have much room for improvement.
Utility model content
The utility model, for the deficiencies in the prior art, provides and a kind ofly has the cement rotary kiln tertiary-air pipe high-performance Alkali resistant brick that stronger alkaline erosion has again good effect of heat insulation.
For realizing the utility model object, provide following technical scheme: cement rotary kiln tertiary-air pipe high-performance Alkali resistant brick, described Alkali resistant brick is piled into tertiary-air pipe cylinder lining, it is characterized in that comprising arc-shaped matrix, several matrixes are spliced into complete ring body, the surfaces externally and internally of matrix is arc surface, the two sides connected with arc surface are inclined plane in opposite directions, described body upper surface offers circular hole, the corresponding circular hole of lower surface offers cylindrical boss, described matrix one side offers the dovetail groove of through upper and lower surface, matrix another side is provided with the strip projection coordinating grafting with dovetail groove.
As preferably, described matrix is hollow brick, and body upper surface circular hole connects matrix inner chamber, and matrix inner chamber is filled with heat-insulating heat-preserving material by circular hole.
As preferably, be laid with some interlaced reinforcement gussets in matrix, several chambers will be divided in matrix.
As preferably, described matrix is high-frequency ceramic.
The utility model beneficial effect: the utility model, by certain moduli tool burning process, burns till a kind of sound construction, and the Alkali resistant brick of alkaline-resisting insulation, its technical indicator: bulk density >=2.20g/cm3 apparent porosity≤25% compressive resistance >=65Mpa.Thermal conductivity factor≤1.1w/m.k (350 DEG C) alkali resistance one-level, the research and development of this product successfully will effectively reduce tertiary-air pipe heat loss, the low 20-30 DEG C of resistance to material that its tertiary-air pipe surface temperature is built by laying bricks or stones than general clay brick or high-alumina brick, the heat energy of manufacture of cement producer is recycled be improved further, improve economic benefit accordingly.

Detailed description of the invention
Embodiment 1: cement rotary kiln tertiary-air pipe high-performance Alkali resistant brick, described Alkali resistant brick is piled into tertiary-air pipe cylinder lining, comprise arc-shaped matrix 1, 4 matrixes 1 are spliced into complete ring body, the surfaces externally and internally (1.1 of matrix 1, 1.2) be arc surface, the two sides (1.3 connected with arc surface, 1.4) be inclined plane in opposite directions, described matrix 1 upper surface 1.5 offers circular hole 1.5.1, the corresponding circular hole 1.5.1 of lower surface 1.6 offers cylindrical boss 1.6.1, described matrix 1 one side 1.3 offers the dovetail groove 1.3.1 of through upper and lower surface, matrix 1 another side 1.4 is provided with the strip projection 1.4.1 coordinating grafting with dovetail groove 1.3.1.Described matrix 1 is hollow brick, and matrix 1 upper surface 1.5 circular hole 1.5.1 connects matrix 1 inner chamber, and matrix 1 inner chamber is filled with heat-insulating heat-preserving material 2 by circular hole 1.5.1.Be laid with 4 interlaced reinforcement gussets 1.7 in matrix 1, be divided into several chambers by matrix 1.Described matrix 1 is high-frequency ceramic.
Raw material is prepared: first select the exotic material of low-porosity to solve intensity and the heat-resisting quantity of product, therefore select a kind of useless high-frequency ceramic to be used as the main material of product.Next selects how empty grog to be used as auxiliary material.Product combines and then adopts chemical bond and Ceramic bond so both to ensure that the normal temperature strength of product and middle elevated temperature strength.
Firing of product, product forms through the high-temperature firing of more than 1350 DEG C after natural drying again, thus ensures that the indices of product is qualified, and particularly the refractoriness under load of product is greater than more than 1400 DEG C, improves the heat-resisting quantity of product further.
