Abstract
The invention discloses a method for producing G-level moderate oil-resistant well cement clinker and cement clinker produced by the method. The method comprises the steps of respectively crushing and grinding limestone ore and coal gangue, filtering by a mesh screen which is smaller than or equal to 80 microns to obtain a raw material; taking 3-4 parts of sulfuric-acid residue and 3-4 parts of steel slag to mix evenly with 83-88 parts of crushed limestone ore raw material and 5-10 parts of coal gangue raw material; and inputting into a rotary kiln to burn to obtain the G-level moderate oil-resistant well cement clinker. Waste can be utilized; industrial waste residue is digested to a certain extent; pollution of the industrial waste residue on the environment is reduced after the sulfuric-acid residue and the steel slag are used; the yield of a mill can be effectively improved; the burnability of the raw material in the burning process of the rotary kiln is obviously improved; the quality stability of the cement clinker is improved; and the comprehensive cost for production is reduced.
Description
Technical field
The present invention relates to the method for anti-oil well cement grog in a kind of G of production level and the cement clinker that the method is produced, particularly a kind ofly can utilize industrial residue such as sulfate slag, slag production to produce the method for anti-oil well cement grog in the G level and the cement clinker that the method is produced.
Background technology
In present G level, anti-oil well cement grog is main material production by limestone ore, coal gangue, iron ore.
During industry was smelted at present, in smelting iron and steel, 1 ton of steel of every production will be discharged the slag waste residue of 0.25 ton of left and right, produced 1 ton of sulfuric acid and can produce 0.7～1 ton of sulfate slag, calculated by this, and the annual slag that produces of China is near 200,000,000 tons, and sulfate slag is near ten million ton.Quantity is very large, is mainly that outdoor big area is stacked at present, and is very large on the impact of surrounding environment.
For this reason, a kind of industrial residue that can effectively reduce improves physical environment to the pollution of environment, just is suggested by the production method of utilizing sulfate slag, slag to produce anti-oil well cement in the G level.
Summary of the invention
The purpose of this invention is to provide the method for anti-oil well cement grog in a kind of production G level that can alleviate to a certain extent industrial pollution and the cement clinker that the method is produced, particularly a kind ofly can utilize industrial residue such as sulfate slag, slag production to produce the method for anti-oil well cement grog in the G level and the cement clinker that the method is produced.
The technical solution adopted for the present invention to solve the technical problems is: limestone ore, coal gangue are pulverized respectively ground＜=80 microns hole sizers get raw material, get sulfate slag 3～4 weight parts, slag 3～4 weight parts, mix with limestone ore raw material 83～88 weight parts, coal gangue raw material 5～10 weight parts after pulverizing, the input calcined by rotary kiln gets anti-oil well cement grog in the G level, then with this grog and the plaster of paris in proportion grinding can produce anti-oil well cement in the G level.
In above-mentioned calcining, the Rotary Kiln Control parameter is preferably as follows: calcining temperature is controlled between 1350～1450 ℃, and the kiln system negative pressure control is built in 80～120pa, and kiln end temperature is controlled at 810～890 ℃, and kiln speed 0.8～1.2 turns/min.
Compared with prior art, the present invention is after using sulfate slag, slag batching, not only can refuse profit and digest to a certain extent industrial residue, alleviate the pollution that industrial residue produces environment, and can effectively improve the grinding machine platform and produce, after raw material enter kiln, raw material burn-ability in the process of calcined by rotary kiln improves obviously, cement clinker quality stability improves, the production comprehensive cost descends, and uses anti-oil well cement indices in the G level of this grog production to meet the technical requirements of standard GB/T 10238～2005.
