Description
Technical field
The present invention relates to ceramic particle technology field, specially a kind of method that extruding dregs porcelain granule prepares brick.
Background technique
Haydite is exactly as its name suggests the particle of ceramic, and the external appearance characteristic of haydite is largely rounded or oval-shaped ball,
But it is not round or ellipse sphere there are also imitative rubble haydite, and is in irregular rubble shape, haydite shape is because of technique difference
And it is different.Its surface is one layer of hard shell, this layer of shell is in ceramic or enamel, there is water proof to protect gas effect, and assign
The higher intensity of haydite is given, because there are many raw material of production haydite, the kind of haydite is also very much, thus color is also just very much, roasting
The color for burning haydite is mostly kermesinus, ember, is lark, grey black, canescence and steel gray there are also special kinds
Color etc., baking-free ceramicite vary in color, generally grey black because solid waste used is different, the lackluster degree in surface, not as good as roasting
It is smooth to burn haydite.
The brick body of existing Haydite bricks preparation method output is excellent light building material, but is used actual
Existing Haydite bricks preparation method can not be made of discarded blast furnace slag in journey, for a long time, both at home and abroad to high titania type blast furnace
The comprehensive utilization of slag has carried out a large amount of research, but the not excellent process by blast furnace slag in conjunction with Haydite bricks, so that high titania type
Blast furnace slag fails to utilize on a large scale, leads to clinker bulk deposition, and slag tip occupies a large amount of soils, not only polluted environment but also caused huge
