Abstract
The technique producing high strength cement with industrial residue, its process steps is as follows: 1), produce clinker: by high silicon rate N=3.10, high aluminium-oxygen modulus P=1.80 and high limestone saturation factor KH=0.80 proportion scheme, carry out dispensing and control blanking carry out grind raw material, raw material homogenizing, then make raw material enter in rotary calciner to calcine, and then produce clinker.2), produce cement products: with microcomputer select flyash, stone powder, clinker, desulfurated plaster, dicyandiamide dreg, six kinds of raw materials of magnesium metal reduction powder according to weight percent carry out dispensing and control blanking carry out grind cement, cement homogenization; and then produce cement products; the invention have the advantage that both meet protection environment, oligosaprobic environmental protection concept drops; and have turn waste into wealth, reduce industrial residue dispose and the positive social effect of production cost; the cement quality produced is stable, and intensity is higher.
Description
Technical field
The present invention relates to technical field of cement production, the technique particularly relating to utilize industrial residue to produce high strength cement.
Background technology
Industrial residue producing cement is utilized to not only conform with protection environment, drop oligosaprobic environmental protection concept; and have turn waste into wealth, reduce industrial residue dispose and the positive social effect of production cost; at present; more existing cement production enterprises successfully utilize industrial residue to produce cement; but; it is not difficult to find out from the existing public technology utilizing industrial residue to produce and is primarily present following deficiency: cement quality is unstable, and intensity is low, it is impossible to meet large-scale construction engineering and use.
Summary of the invention
It is an object of the invention to provide the technique utilizing industrial residue to produce high strength cement; this technique had both met protection environment, had dropped oligosaprobic environmental protection concept; and have turn waste into wealth, reduce industrial residue dispose and the positive social effect of production cost; and the cement quality of this technique production 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: utilizing industrial residue to produce the technique of high strength cement, its process steps is as follows:
1, clinker is produced: by high silicon rate N=3.10, high aluminium-oxygen modulus P=1.80 and high limestone saturation factor KH=0.80 proportion scheme, carbide slurry, white lime slag, quartz sand ore dressing mud, fine iron ore ore dressing mud, five kinds of raw materials of flyash are selected to carry out dispensing according to weight percent and control blanking and carry out raw mill, raw material homogenizing with microcomputer, then make raw material enter in rotary calciner to calcine, and then produce clinker.
2, cement products is produced: select flyash, stone powder, clinker, desulfurated plaster, dicyandiamide slag, six kinds of raw materials of magnesium metal reduction powder carry out dispensing according to weight percent and control blanking and carry out cement grinding mill, cement homogenization with microcomputer, and then produce cement products.
According to the above-mentioned technique utilizing industrial residue to produce high strength cement, its feature is: the described carbide slurry produced in clinker, white lime slag, quartz sand ore dressing mud, fine iron ore ore dressing mud, five kinds of raw material microcomputers of flyash are selected and according to weight percent are: carbide slurry 40%-55%, white 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%.
According to the above-mentioned technique utilizing industrial residue to produce high strength cement, its feature is: select the raw material according to weight percent to be with microcomputer in described flyash, stone powder, clinker, desulfurated plaster, dicyandiamide slag, six kinds of Raw Material for Cement Production products of magnesium metal reduction powder: flyash 18%-20%, stone powder 6%-8%, clinker 50%-55%, desulfurated plaster 11%-14%, dicyandiamide slag 5%-7%, magnesium metal reduction powder 4%-5%.
The invention have the advantage that the present invention had both met protection environment, dropped oligosaprobic environmental protection concept; and have turn waste into wealth, reduce industrial residue dispose and the positive social effect of production cost; and the cement quality of production is stable, intensity is higher, can meet large-scale construction engineering and use.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described:
Utilize the technique that industrial residue produces high strength cement, process steps is as follows: 1, produce clinker: by high silicon rate N=3.10, high aluminium-oxygen modulus P=1.80 and high limestone saturation factor KH=0.80 proportion scheme, carbide slurry, white lime slag, quartz sand ore dressing mud, fine iron ore ore dressing mud, five kinds of raw materials of flyash are selected to carry out dispensing according to weight percent and control blanking and carry out raw mill, raw material homogenizing with microcomputer, then make raw material enter in rotary calciner to calcine, and then produce clinker.2, cement products is produced: select flyash, stone powder, clinker, desulfurated plaster, dicyandiamide slag, six kinds of raw materials of magnesium metal reduction powder carry out dispensing according to weight percent and control blanking and carry out cement grinding mill, cement homogenization with microcomputer, and then produce cement products.
In the present embodiment: the described carbide slurry that produces in clinker, white lime slag, quartz sand ore dressing mud, fine iron ore ore dressing mud, five kinds of raw material microcomputers of flyash are selected and according to weight percent are: carbide slurry 49%, white lime slag 37.2%, quartz sand ore dressing mud 3.5%, fine iron ore ore dressing mud 2.8%, flyash 7.5%.
In the present embodiment: described flyash, stone powder, clinker, desulfurated plaster, dicyandiamide slag, six kinds of Raw Material for Cement Production products of magnesium metal reduction powder select the raw material according to weight percent to be with microcomputer: flyash 18%, stone powder 7%, clinker 53%, desulfurated plaster 12%, dicyandiamide slag 6%, magnesium metal reduction powder 4%.
The method have the benefit that the present invention had both met protection environment, dropped oligosaprobic environmental protection concept; and have turn waste into wealth, reduce industrial residue dispose and the positive social effect of production cost; and the cement quality of production is stable, intensity is higher, can meet large-scale construction engineering and use.
Embodiment described above is only to be described the preferred embodiment of the present invention; not design and protection domain to the present invention are defined; on the premise of without departing from design concept of the present invention; various modification that in this area, technical scheme is made by ordinary skill technical staff and improvement, all should fall into protection scope of the present invention.
