Abstract
The invention discloses a process for producing high-strength cement by using industrial waste residues, which comprises the following process steps: 1) the production of a cement clinker: carrying out proportioning and controlling fed materials to carry out raw material grinding and raw material homogenizing according to a proportioning scheme that the high silicon rate N is 3.10, the high alumina rate P is 1.80 and the high limestone saturation rate KH is 0.80, feeding raw materials into a rotary calcining kiln to be calcined, and then producing the cement clinker; and 2) the production of a cement product: selecting six raw materials such as fly ash, stone powder, the cement clinker, desulfurization gypsum, dicyandiamide residues, and metal magnesium reduced powder by using a microcomputer to proportion in percentage by weight, controlling fed materials to carry out cement grinding and cement homogenizing, and then producing the cement product. The process disclosed by the invention has the advantages that the process both complies with the environmental-friendly concept of protecting the environment and reducing the pollution, and has the positive social effects of changing waste material into things of value and reducing the disposal and production costs of industrial waste residues, and produced cement is stable in quality and high in strength.
Description
Technical field
The present invention relates to technology of producing cement field, relate in particular to the technique of utilizing industrial residue to produce high strength cement.
Background technology
Utilize industrial residue producing cement not only to meet protection of the environment, fall oligosaprobic environmental protection concept; and have and turn waste into wealth, reduce that industrial residue is disposed and the positive social effect of production cost; at present; more existing cement production enterprises successfully utilize industrial residue to produce cement; yet; from the existing public technology that utilizes industrial residue to produce, be not difficult to find out mainly and have the following disadvantages: cement quality is unstable, and intensity is low, can not meet large-scale construction engineering and use.
Summary of the invention
The object of this invention is to provide the technique of utilizing industrial residue to produce high strength cement; this technique had both met protection of the environment, had fallen oligosaprobic environmental protection concept; and have and turn waste into wealth, reduce that industrial residue is disposed and the positive social effect of production cost; and the cement quality of this explained hereafter is stable; intensity is higher, can meet large-scale construction engineering and use.
For achieving the above object, the technical solution adopted in the present invention is: utilize industrial residue to produce the technique of high strength cement, its technological process step is as follows:
1, produce cement clinker: by high silicon rate N=3.10, high aluminium-oxygen modulus P=1.80 and high Wingdale saturation exponent KH=0.80 proportion scheme, with microcomputer, select calcium carbide mud, lime slag, quartz sand ore dressing mud, fine iron ore ore dressing mud, five kinds of raw materials of flyash according to weight percent, prepare burden and control blanking and carry out raw mill, raw material homogenizing, then make raw material enter into rotary calciner and calcine, and then produce cement clinker.
2, produce cement products: with microcomputer, select flyash, stone flour, cement clinker, desulfurated plaster, dicyandiamide slag, six kinds of raw materials of magnesium metal reduction powder according to weight percent, prepare burden and control blanking and carry out cement grinding mill, cement homogenization, and then producing cement products.
According to the above-mentioned industrial residue that utilizes, produce the technique of high strength cement, its feature is: the calcium carbide mud in described production cement clinker, lime slag, quartz sand ore dressing mud, fine iron ore ore dressing mud, five kinds of raw materials of flyash are selected according to weight percent with microcomputer and are: calcium carbide mud 40%-55%, lime slag 35%-40%, quartz sand ore dressing mud 3.5%-4.0%, fine iron ore ore dressing mud 2.7%-3.0%, flyash 7%-8%.
