Description

Synthetic ruby based on blast furnace slag and manufacture method thereof

Technical field

The invention belongs to artwork production field, is to utilize the industrial solid castoff producing in iron manufacturing process specifically---synthetic ruby 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, new technology, the novel process of active demand in the market to blast furnace slag comprehensive utilization.

Ruby is a kind of jewel of preciousness, and color takes on a red color or pink, bright-coloured charming, and hardness is very high, is difficult for damage and deterioration, thereby is subject to since ancient times liking of people.But natural ruby reserves are very rare, rare, thereby expensive, ordinary consumer is difficult to have.

Therefore,, in order to meet the growing needs of ordinary consumer, people adopt artificial technology to produce synthetic ruby.Existing technology is that aluminium sesquioxide and the chromium sesquioxide powder very high taking purity manufactured synthetic ruby as raw material, and the price comparison of raw material is expensive, so the cost of product is higher.The contriver of this patent is engaged in the development work of artificial jade from April, 2009, has developed the multiple products such as artificial white jade, black jade, jasper, carbuncle, and excellent property, has broad application prospects in artwork field.

Summary of the invention

The object of the invention is to overcome the defect that conventional art exists, taking blast furnace slag as raw material production synthetic ruby.Feature of the present invention is taking 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 synthetic ruby.

Preparation method of the present invention is:

1. the raw materials for production of synthetic ruby and proportioning:

Blast furnace slag: 50-90%

PbO:1-20%

Al ₂O ₃：10-50%

Above-mentioned raw materials can use also simultaneously and can partly use, and determines according to the performance requriements to product and production cost.

2. the preparation technology of synthetic ruby is:

(1) weigh on request various raw materials;

(2) by block raw material crushing, grinding;

(3) various raw materials are put into container and mix and stir, make material composition even;

(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, heat up with stove; Heating temperature is 800-2000 DEG C, 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 synthetic ruby blank, then according to the difference of concrete product chisel and carve, polishing, glossing, finally obtain finished product.

     

Beneficial effect of the present invention:

Synthetic ruby prepared in accordance with the present invention takes on a red color or pink, bright-colored charming, quality is hard, fine and smooth, tough, bright and glittering, 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 taking 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 material 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.
