Abstract
The present invention relates to shale CHARACTERISTICS OF TAILINGS SAND decorative brick and manufacturing methods, are sintered according to the following weight percentages by following raw materials according: shale: 95%-98%, CHARACTERISTICS OF TAILINGS SAND: 2%-5%.Its manufacturing method includes the following steps: that shale and CHARACTERISTICS OF TAILINGS SAND are rolled through wet type rolling, then through coarse crushing to roller, it is fine crushing to roller grind, make up to suitable granularity；Mixed raw material stirs evenly after adding water, is homogenized in ageing library；Mud item is cut into adobe using multi-line cutting machine by vacuum extruding form；Implement semi-stiff extrusion process, will be dried, roast on adobe direct code to kiln car, sintering control maximum temperature is 950-1000 DEG C, is kept for 5-6 hours, firing time 36-48 hours at the maximum temperature；Kiln discharge sorting.Local shale resource abundant had both been utilized for Chengde area, the especially shale and CHARACTERISTICS OF TAILINGS SAND of Kuancheng Manchu Nationality Autonomous County in the present invention; CHARACTERISTICS OF TAILINGS SAND is set to turn waste into wealth again; environment is protected, building material field is opened, the decorative brick economic results in society of shale CHARACTERISTICS OF TAILINGS SAND sintering are huge.
Description
Technical field:
The present invention relates to building materials fields, especially shale CHARACTERISTICS OF TAILINGS SAND decorative brick.
Background technique:
The heat insulation property of common brick, freeze-thaw resistance and compression strength are all poor, and many cities are forbidden to use reality
Heart clay brick, i.e., cannot be again with clay as firing raw material, it is therefore desirable to which the new raw material of one kind carrys out brickmaking, while can be reduced arable land
Clay uses.There is shale resource abundant in the Kuancheng Manchu Nationality Autonomous County of Chengde City, Hebei Province, while iron ore here is relatively more, produces
Raw tailing causes seriously to pollute to soil, and huge security risk is formed during storing.How by shale and CHARACTERISTICS OF TAILINGS SAND
Combine development and utilization, becomes problem in the urgent need to address.Patent No. 200510095347.x mine shale sintering system
In product and preparation method thereof, primarily directed to high iron low silicon (dioxide-containing silica is lower than 45%) and the low ferro-aluminum tailings utilization of high calcium
The method utilized is not appropriate for the firing of Chengde area decorative brick.
Summary of the invention:
It is an object of that present invention to provide the shale of suitable Chengde area, especially Kuancheng Manchu Nationality Autonomous County and CHARACTERISTICS OF TAILINGS SAND to fire
Shale CHARACTERISTICS OF TAILINGS SAND decorative brick and manufacturing method.The shale resource that local abundance can be made full use of in this way, is allowed to apply and build
Material field, and the use of clay can be reduced, CHARACTERISTICS OF TAILINGS SAND can also turn waste into wealth, and not only realize recycling economy development, but also can protect
Environment.
To achieve the above object, the technical solution adopted by the present invention is that: a kind of shale CHARACTERISTICS OF TAILINGS SAND decorative brick, it is characterised in that

The manufacturing method of the present invention includes the following steps:
(1) shale and CHARACTERISTICS OF TAILINGS SAND are rolled through wet type rolling, then through coarse crushing to roller, it is fine crushing to roller grind, make up to suitable
The granularity of conjunction.
(2) it stirs evenly after mixed raw material being added water, is homogenized in ageing library.
(3) mud item is cut into adobe using multi-line cutting machine by vacuum extruding form.
(4) implement semi-stiff extrusion process, will be dried, roast on adobe direct code to kiln car, sintering control maximum temperature is
It 950 DEG C -1000 DEG C, is kept for 5-6 hours, firing time 36-48 hours at the maximum temperature.
(5) kiln discharge sorting.
