Performance Characteristics of Copper and Coal Slag

2016-10-24  Six copper slag and 2 coal slag abrasive products from 6 different suppliers were selected for evaluation. A G-40 steel grit was used as a control. Triplicate six-inch (15-centimeter) by six-inch (15-centimeter) panels were blasted to SSPC-SP 5, White Metal, using each test abrasive and the G-40

Frequently Asked Questions What is Coal Slag? US

What is coal slag? This stuff is boiler slag, which is a recycled product from coal burning plants. When coal is “fired” at over 2500 degrees it melts and produces a by-product called slag. When the slag is cooled through a process called vitrification, it crystallizes, forming sharp, angular granules in
