High Quality of Metering Nozzle used in the former tundish smelting furnace- working for 15 hours

Products Features:

Zirconia Metering Nozzle used in the tundish we are producing has the high purity and high density, strong the chemical stability at high temp. state, high strength, excellent crushing resistance, erosion of the steel liquid and slag resistance, strong thermal shock stabilities, super low speed of the diameter enlargement of the nozzle, extremely increased the working life of the nozzle.

Working life of the Zirconia Metering Nozzle Insert

For the working life of our Zirconia Metering Nozzle used in the tundish, based on the different smelting steel types in tundish, different casting times of the furnace, the working lifes are different. Fangming NewM can produce the requested the zirconia metering nozzles according to the clients' demand for the shape and sized, the normal working life can reached 15 hours continuously.

The Tundish smelting technology of using this kind of nozzles is very old, and one time use for the nozzle and tundish. WIth the seperate types of the upper and lower nozzles in the tundish developed. it has been instead more and more.

Production Process

Zirconia Metering Nozzle in tundish we produced is taking the world's advance automatic production equipment and technology, and taking the high quality of the zirconia grain and powder, adding other additives, through the mixing, drying, inspecting, pressing, inspecting,drying, sintering,inspecting, etc. standard andsystem process, then produce the exact size, high quality,longer-working life of the zirconia lower nozzle in tundish.

Chemical composition and Physical Properties

Usual Size of the metering nozzle:

Height: 90-110mm, middle hole diameter: 12-21mm. Matched with the well block together directly.

Bonded Style

Our zirconia lower nozzle is usually embedded in the alumina or corundum and graphite body with the refratcory motar. Also export to oversea countries, and the buyer press the zirconia insert into the body directly.

Size Tolerance:

ZrO2 Insert: Middle Hole Diamter:+-0.2mm, other sizes: +-0.5mm.

Al2O3 Body:Middle Hole Diamter:+-0.2mm, other sizes: +-1mm.

Packing:

66pcs/carton, 30cartons/wooden box with fumigation treatment.
