| Abstract |
With environmental, energy-saving, and legislation considerations becoming increasingly important, there is a need for a major improvement in slag handling. The metallurgical industry is directing its efforts into minimizing and processing the slags to achieve sustainable development and a circular economy. An important pillar for the advanced slag treatment is an automated and smooth tapping operation. A well-functioning tap-hole is an essential requirement for stable melting/refining processes as well as for reliable smelter operation. Slag should be tapped from the furnace balancing between production rate, capacity of the downstream vessels, and safety of the operators. In stationary vessels, tapping flow rate and slag flow behavior are dependent on conditions in the furnace (e.g. pressure, bath level, and liquid properties) as well as on tap-hole geometry and its wear level. In conventional slag tapping there can be challenges in maintaining a steady flow. The S-TAP Slag Slide Gate Technology is a solution that enables an accurate regulation of the slag tapping flow rate and quick reaction by tap-hole closing. This implies controlled and steady slag flow, minimized splashing around the tap-hole surroundings, improved safety due to an immediate tap-hole closing in case of an emergency, and brings a higher degree of automation in a metallurgical plant. A vision towards fully automated tapping is also presented in the paper. |
