Ladle upper&lower Nozzle

The company provides a wide range of products and services used in converter, EAF, Ladle, tundish and other kilns and furnaces. We also equipped with world advanced facilities such as Laeis automatic hydraulic press HPF2500, Eirich R19 mixer, Shimadzu made XRF-1800 sequential X-Ray fluores-cence spectrometer, by focusing on product research and development and quality control. Our products also supply to Asia , Europe, America and Africa and other countries and regions.

Ladle Upper Nozzle

The high-quality upper and lower nozzle are made of sintered corundum, fused corundum, fused mullite, etc. as the main raw materials. They are bonded with new resin combination, formed by high pressure, fired by high temperature hydrogenation, and free from oil immersion. with high strength, good high temperature resistance and corrosion resistance, strong thermal stability, long service life, etc.
