Description

Artificial ink-stone and manufacture method thereof based on slag

Technical field

The invention belongs to the artwork production field, is to utilize industrial solid castoff specifically---artificial ink-stone and manufacture method thereof that slag is produced.

Background technology

Slag is the industrial solid castoff that produces in the steelmaking process, accounts for the 15-20% of crude steel output, and enterprise generally adopts the form of air storage to handle slag, and this has taken a large amount of soils on the one hand, and on the other hand, slag also can pollute peripheral ecological environment.

For many years, it has been recognized that slag also is a kind of important resource, and adopted multiple technologies that slag is fully utilized, as reclaim wherein iron, do smelt fusing assistant, be used for building the road, backfill, production building materials etc., but all there is defective to a certain extent in these technology, as still can produce industrial solid castoff after reclaiming iron, also there are problems such as quality instability, energy consumption height in the building materials of producing, in addition, the above-mentioned approach majority that utilizes still belongs to extensive low value-added utilization, the economic benefit that produces is limited, so the enthusiasm of enterprise is not high.

For these reasons, press for new technology, novel process to slag comprehensive utilization in the market.

Since ancient times, ink-stone is exactly a kind of artwork that is loved by the people, and has very high appreciating and reserve value.The chemical ingredients test shows, the composition of ink-stone and slag have similarity significantly.The contriver of this patent is engaged in the development work of artificial jade from April, 2009, has developed multiple products such as artificial white jade, black jade, jasper, and excellent property has broad application prospects in the artwork field.

Summary of the invention

The objective of the invention is to overcome the defective that conventional art exists, is that raw material production has high value-added product with the slag---artificial ink-stone, thus open up a new approach for Multipurpose Utilization of Steel Slag.Feature of the present invention is to be main raw material with the slag, adds certain quantity of additive simultaneously, passes through weighing, pulverizing, grinding, batch mixing, stirring, melting, chisels and carves the artificial ink-stone of prepared.

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

(6) from crucible, take out artificial ink-stone blank, chisel and carve according to the difference of concrete product then, finally obtain finished product.

Beneficial effect of the present invention:

Artificial ink-stone quality exquisiteness prepared in accordance with the present invention is tough and tensile, gloss is gentle soft, and has a good mechanical performance, as higher hardness, toughness and wear resistance, high thermal resistance, erosion resistance, weathering resistance etc., can be used for the artwork field, have broad application prospects.

The present invention for the production raw material production has high value-added product, has realized the high value added utilization to slag with the 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 that uses is as Chemicals common on the market, and is cheap.

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

In sum, the present invention has advantages of high practicability and application value.
