Liquid nozzle

spraytungstenmolybdenum

Product overview
Glass, rock and ceramic wools as well as glass fibers are produced at temperatures up to approx. 1700°C. The molten material flows through outflow nozzles made from molybdenum (Mo) or tungsten (W); downstream the melt is blown or spun to form insulating wool or fibers.

Your advantages at a glance

• High corrosion resistance suitable for high-temperature melt environments
• Extended service life with optional iridium (Ir) and rhenium (Re) inserts
• Custom nozzle geometries and insert arrangements to meet specific process requirements

Quality through durability
A centrically aligned, precisely dosed melt jet is essential for final product quality. Plansee supplies high-temperature-resistant nozzles in Mo and W that ensure a controlled, centered melt flow. Precious-metal inserts (Ir, Re) are bonded using a specialized joining technique to maximize wear and corrosion resistance and extend service life.

Application details
Nozzles are applied in production lines for glass wool, rock wool, ceramic wool and glass fiber. The molten material passes through the nozzle and is subsequently blown or spun to produce insulating wool or continuous fibers.

Other products for glass manufacturing
In addition to nozzles, Plansee offers a range of molybdenum and tungsten components designed to improve efficiency and durability of glass production equipment. Consult the product range for complementary system components and solutions.
