Description

Based on artificial legendary luminous pearl and the manufacture method thereof of blast furnace slag

Technical field

The invention belongs to artwork production field, is to utilize the industrial solid castoff producing in iron manufacturing process specifically---artificial legendary luminous pearl and manufacture method thereof that blast furnace slag is produced.

Background technology

Blast furnace slag is the industrial solid castoff producing in iron-making production, is one of industrial solid castoff that China's quantity discharged is maximum, and according to statistics, 1 ton of iron of every refining will produce 0.3-1 ton of blast furnace slag.Enterprise generally adopts the mode of air storage to process blast furnace slag, and this has taken a large amount of soils on the one hand, on the other hand, and objectionable impurities meeting polluted underground water and ambient air in blast furnace slag, thereby ecotope is produced to serious harm.

For many years, people have adopted multiple technologies to fully utilize blast furnace slag, as produce cement and concrete, or operating mine slag wool, devitrified glass, agricultural fertilizer etc., but these technology all exist defect to a certain extent, during as production cement and concrete, the mechanical performance index of product is unstable, and these application majorities belong to low value-added utilization, the benefit of generation is limited.For these reasons, in the market in the urgent need to new technology, novel process to blast furnace slag comprehensive utilization.

Legendary luminous pearl is a kind of jewel of preciousness, can send at night beautiful radiance, is subject to since ancient times liking of people.But natural legendary luminous pearl reserves are little, thereby expensive, can not meet the growing needs of ordinary consumer.If adopt artificial technology to produce artificial legendary luminous pearl, there is undoubtedly important value and significance.

Summary of the invention

The object of the invention is to overcome the defect that traditional Comprehensive Utilization Technology of Blast Furnace Slag exists, take blast furnace slag as raw material production, there is high value-added product---artificial legendary luminous pearl, thus open up a new approach for the comprehensive utilization of blast furnace slag.Feature of the present invention is take blast furnace slag as main raw material, adds a certain amount of additive simultaneously, through weighing, pulverizing, grinding, batch mixing, stirring, melting, chisel and carve, polishing, glossing prepare artificial legendary luminous pearl.

(4) pour the raw material mixing into crucible, put into smelting furnace and carry out melting, be characterized as: raw material is put into crucible, at room temperature pack smelting furnace into, with stove, heat up; Heating temperature is 800-1650 ℃, insulation 2-30 hour; Furnace cooling, in process of cooling, fire door is closed all the time;

(5) product is cooled to after room temperature, from stove, takes out;

(6) from crucible, take out artificial legendary luminous pearl blank, then according to the difference of concrete product chisel and carve, polishing, glossing, finally obtain finished product.

     

Beneficial effect of the present invention:

Artificial legendary luminous pearl prepared in accordance with the present invention can be sent beautiful fluorescence at night, quality exquisiteness is tough and tensile, gloss is gentle soft, and there is good mechanical property, as higher hardness, toughness and wear resistance, high thermal resistance, erosion resistance, weathering resistance etc., can be used for artwork field, have broad application prospects.

The present invention has high value-added product take blast furnace slag as production raw material production, has realized the high value added utilization to blast furnace slag, for a new way has been opened up in the comprehensive utilization of industrial solid castoff.

Raw material sources of the present invention are extensive, and the additive of use is for Chemicals common on market, cheap.

Aspect preparation technology, preparation technology of the present invention is simple, lower to the requirement of equipment, and operator's technical ability is not had to particular requirement yet, and common laborer can operate.

In sum, the present invention has higher practicality and application value.
