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

(6) from crucible, take out artificial ink-stone blank, then according to the difference of concrete product, chisel and carve, 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 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 be take blast furnace slag and is had high value-added product 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.
