Description
Technical field
The present invention relates to a kind of preparation method of flase floor, belong to the metallurgical slag treatment facility.
Background technology
Produce a large amount of steel (iron) slags in the steelmaking process, like hot metal pretreatment slag, residual casting slag etc.Residual casting slag forms in ladle, and alumina content is higher and contain higher molten steel, after deslagging is poured slag ladle into, at the bottom of slag ladle, forms large slag.These large slags often need measures such as explosion, cutting, weight fragmentation just can go into stove to use, the manpower and materials of labor, and contaminate environment, and influence the recycling of slag steel.
Simultaneously, iron and steel enterprise produces a large amount of solid waste, like tailings, flyash, waste refractory materials etc., has taken a large amount of soils, and contaminate environment.
Along with national environmental standard improves constantly, iron and steel enterprise carries forward vigorously energy-saving and emission-reduction, improves the environmental protection of enterprise level.
Therefore, how to make full use of iron and steel enterprise's secondary resource, energy-saving and emission-reduction, cost efficiency becomes the urgent problem that needs solution.
Summary of the invention
In order to reduce in the metallurgical slag treating processes generation that sticks together of bulk slag, realize that the slag steel recycles fast, make full use of the solid waste of iron and steel enterprise simultaneously, the present invention provides a kind of metallurgical slag to handle the preparation method with flase floor.
The present invention includes following sequential steps:
Proportioning raw materials by following mass parts:
Tailings 5-10 part of granularity 10-20mm; Tailings 15-20 part of granularity 5-10mm;
Tailings 12-20 part of granularity 3-5mm; Granularity is less than waste refractory materials 10-15 part of 5mm;
Granularity is less than 3mm blast furnace granulated slag 5-15 part; Granularity is less than flyash 20-30 part of 0.088mm;
Sintering machine head end dedusting ash 5-10 part; Cement 20-30 part.
Above-mentioned raw materials is stirred, and then add the water of 10～18 parts of mass parts, mixing becomes mixed slurry;
With above-mentioned mixed slurry, casting is template (thickness is 40-50mm) in model;
With the template of casting, be maintenance 3 days in the steam more than 50 ℃ in temperature, natural curing became flase floor in 4 days then.
Described waste refractory materials can use discarded clay brick to substitute;
Described waste refractory materials can use the compound of discarded clay brick and other waste refractory materials to substitute, and the ratio of discarded clay brick and other waste refractory materials is any.
Flase floor is dressed up " well " font structure with the iron wire fixation group to be arranged in the slag ladle; Can avoid the generation of bulk slag stone roller; Reached and prevented that residual steel from forming the purpose of large slag in slag ladle, slag can be divided into some lumpiness of utilizing standard again that reach simultaneously, reduced the slag processing cost; Utilize the solid waste of iron and steel enterprise to produce flase floor, practiced thrift resource, comprehensive reduction processing cost has been protected environment.

(3) moulding:
With above-mentioned slip, casting is template (thick 40-50mm) in model.
(4) maintenance:
With the template of casting, maintenance is after 3 days in the steam of 65 ℃ of temperature, and natural curing became flase floor in 4 days.
(5) assembled formation:
Flase floor is dressed up " well " font structure with the iron wire fixation group, be installed in the slag ladle.
