Abstract
The invention discloses a preparing method for an environment-friendly silicious dry-type material, which includes the following steps in sequence: smashing quartz sands into small particles of 0.3 mm-3 mm, and screening the small particles into two specifications based on the standard of particle sizes of 3 mm and 0.3 mm-3 mm; fine grinding partial small particles into fine powder with the particle size of 0.088 mm; weighing 5% of anhydrous dextrose and 0.7% of borax, stirring for 18-22 min for premixing, and conveying the mixture to a mixing system after premixing; loading 14% of quartz sands with the particle size of 3 mm, 64.3% of quartz sands with the particle size of 0.3 mm-3 mm and 16% of quartz sands with the particle size of 0.088 mm to a mixing system tank, and mixing for 4-6 min and conveying the mixture to a mixing system; performing split charging on the quartz sands, the anhydrous dextrose and borax simultaneously to obtain the dry-type finished product. The environment-friendly silicious dry-type material prepared through adopting the method can be used for smelting ordinary steel, and greatly reduces consumption of mineral resources, thereby greatly reducing steelmaking cost with respect to raw materials and the smelting requirement of ordinary steel is met without lowering the product quality.
Description
Technical field
The present invention relates to field of metallurgy, the preparation method of the siliceous dry materials of especially a kind of environment-friendly type.
Background technology
The dry materials of producing at present common steel grade and excellent steel grade is all that to take magnesia or forsterite be the main raw material component, adopt solid phenolic resin as tamanori, this magnesium dry-type stock general work-ing life is about 24～45 hours, and while producing common steel grade, general needs 8～12 hours, utilization ratio, less than half, waste Mineral resources, and steel-making cost is very high.Traditional dry materials is generally usingd powdered phenol-formaldehyde resin as tamanori.This tamanori contains a certain amount of formaldehyde and free phenol, produces very smelly harmful smoke in baking and use procedure, and harm environment and worker are healthy; Carbon residue after phenolic resin carbonized stays in cylinder-packing, also can bring the problem of molten steel recarburization; Resol, as organism, is easily brought hydrogen into again when the smelting low carbon steel in molten steel simultaneously.Hydrogen is very serious on the impact of steel quality, easily causes the quality defects such as white point in steel, hairline, pore.
Summary of the invention
Technical problem to be solved by this invention just is to provide the preparation method of the siliceous dry materials of a kind of environment-friendly type, the siliceous dry materials of the environment-friendly type that this preparation method makes not only can be saved Mineral resources, reduce steel-making cost, and can thoroughly solve resol to the pollution of environment and the harm of workman's health.
For achieving the above object, the present invention adopts following technical scheme: the preparation method of the siliceous dry materials of a kind of environment-friendly type is characterized in that: comprise the following steps successively:
A) with roller crusher, quartz sand powder is broken into to the small-particle of 0.3mm～3mm, and small-particle is sieved into to 3mm particle diameter and 0.3mm～two kinds of 3mm particle diameters specification by the particle diameter difference;
B) the part small-particle is finely ground into to the fine powder that particle diameter is 0.088mm with ball mill;
C) take dextrose anhydrous: 5%; Borax: 0.7%; Pour the forced stirrer stirring into and carry out pre-mixing in 18～22 minutes, be delivered to mixing system after pre-mixing;
D) by the quartz sand of 3mm particle diameter: 14%; 0.3 the quartz sand of～3mm particle diameter: 64.3%; 0.088mm the quartz sand of particle diameter: 16%; Be filled in the Preblend system PBS tank, batch mixing was delivered to mixing system after 4～6 minutes;
E) quartz sand, dextrose anhydrous and borax are stirred simultaneously in mixing system and carry out packing after 5～7 minutes and obtain the dry materials finished product.
As preferably, described c) in step, churning time is 20 minutes.
As preferably, described d) in step, mixing time is 5 minutes.
As preferably, described e) in step, churning time is 6 minutes.
The siliceous dry materials of the environment-friendly type that the present invention makes is smelted ordinary steel, utilization ratio reaches more than 90%, greatly saved the consumption of Mineral resources, and, quartz sand is one of the widest mineral of earth surface distribution, 175.00 yuan of existing market price raw material bids per ton, with the magnesia of 1950.00 yuan, compare, main raw material per ton is with regard to cost-saving 1775 yuan, to sum up consumption and price factor, preparation cost of the present invention is only 1/20th of magnesium dry-type stock, thereby greatly reduce steel-making cost from raw material, when particularly reducing costs, can also meet the smelting requirements of ordinary steel fully, do not reduce product quality.
