Marble and Stone: extraction and fabrication process
The marble extraction process begins by identifying potential quarry sites through a comprehensive review of geological maps for the area and from site inspections to evaluate any emerging masses from which to deduce the characteristics and quality of the material. This happens usually in areas where ancient quarries pre-existed. The cultivable layer materializes …

Manufacturing Process From Ore To Stainless Steel: A Step …
Continuous casting is a method used to produce large, continuous lengths of steel. In this process, the molten steel is poured into a water-cooled copper mold, which helps solidify the steel into a semi-finished form. As the steel solidifies, it is continuously pulled out of the mold, resulting in a continuous strand of solid steel.
