A cleaner slag

Figure 1 These grates used to have peaks and valleys at the top so that they could solidly support the sheet metal being laser-cut while at the same time provide room for the molten metal to drop away from the sheet and adhere to the slat. Without regular slat cleaning, however, the molten metal has nowhere to fall, possibly causing a part to be welded to the grating or simply causing the molten metal to splash back onto the underside of the laser-cut part. Any metal fabricator that has been laser cutting for several years learns a few hard lessons along the way. One of the most painful is the need to stay on top of slat cleaning and replacement. Does this scenario sound familiar? The molten metal is going to harden, adhere to the top of the grating, and weld that sheet metal part and sheet to the slats.

Dalmia - Slag Cleaning

By extracting vanadium from the steel manufacturing process, the steel becomes cleaner and you get slag that can be used externally. In addition, you get potential environmental benefits of more than 1 million tonne CO2 and 2 TWh each year for the Swedish steel industry. LD slag is generated during the production of steel in a so-called LD converter where pig iron is converted to steel through oxidation of converted coal. Since pig iron contains approximately 0.

Reducing headaches associated with slag on laser grating

Copper slag from copper matte smelting contains iron, which forms fayalite Fe 2 SiO 4 as the major constituent. Because of its favorable physico-mechanical properties, copper slag has uses such as concrete aggregates, ballast, and abrasives. However, the demand for copper slag for such applications is decreasing in advanced countries such as Japan. In recent years, the depletion of high-grade iron ores and increasing demands for iron resources have resulted in an interest in the development of methods for iron recovery from low-grade metallurgical wastes.

The result was a new measurement tool which provided an accurate identification of steel vs slag for the furnancemens operation. The real time images give operators the tools they need to optimize the tapping process and maximize yield. By minimizing slag carryover into the ladle, the operator lowers the amount of reducible oxides in the slag which must be treated at secondary processing, lowering costs and producing a cleaner steel. The system also acts as a training tool for new operators, and allows for more consistent tapping practices for all operators. Thermal Slag Detect allows steelmakers to measure the tapping process.
