Stoppers and Nozzles
Control of the molten metal stream is of paramount importance when using bottom pour ladles. Foseco offers a variety of stoppers and nozzles for steel foundries in a range of materials to suit all applications.
VISO isostatically pressed carbon bonded alumina graphite monoblock stoppers are the ideal choice for small to medium sized bottom pour steel foundry ladle applications. ROTOLOK stoppers offer the steel founder a reliable single use refractory component designed to operate even with the most aggressive steel grades. ROTOLOK offers excellent thermal shock resistance and are ideal for very large steel ladles.
VAPEX ceramic / carbon bonded alumina graphite nozzles are available in standard taper and reverse taper designs and are ideally suited for steel foundry applications.
VAPEX cross bore nozzles produce a smooth, concentrated pouring stream and offer significant benefits over conventional designs.
VISO / VAPEX MULTI-LIFE Nozzles: Normally a steel foundry nozzle is a One-Shot product. As the market demands improvements, the new zoned nozzle for multiple usage has been invented. The nozzle can be used as often as the VISO stopper which leads to a safer work environment, less stock and higher productivity.
