ZrO2 Tundish Lower Nozzle High Performance Least 12-15hrs Working Time

Product Specification

        High Performance of zirconia Lower nozzle used in the large capacity of the tundish for 12-15hrs 

Products Features:

Zirconia Lower 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 lower nozzle 

For the working life of our zirconia insert used in the tundish lower nozzle,  based on the different smelting steel types in tundish,  different casting times of the furnace, different types of the tundish nozzle, the working lifes are different. Fangming NewM can produce the requested the zirconia upper nozzle, lower nozzle, quick-changable nozzle, metering nozzles according to the clients' demand for the shape and sized, the normal working life can reached 10-15 hourscontinuously.

Production Process

Zirconia Lower nozzle used in the 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

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:

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

Packing:

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

Exported Countries

India, Pakistan, Iran, Thailand, Turkey, Peru, USA, etc.

Company Introduction

Setup in Sep.,2015,Fangming NewM. is one high-new technology producing enterprise of the high purity and the ultra-high temperature new type of thecomposite nano-ceramic materials and products based on the raw material of the zirconia, and the one manufacturer of urgently much needed to breakthrough key technologies in the new materials category advocated and developed by the state in the 2025 planning catalogue, of the rare oxide composite new materials of the super high temperature structural ceramics, which are applied in the extreme environments.

Up to now, we have gained the ISO9001:2015 Quality Management System Certificate, ISO14001:2015 Environment Management System Certificate, OHSAS18001:2007 occupational Health&Safety Management System ,ISO50001:2011 Energy Management System Certificate, etc. Certificates.Meantime, we have owned the 8 related invention patents and utility model patents.

Large size, super special shaped super high temp. zirconia ceramics, we will offer the comprehensive and integrated super high temperature, strong crushing resistance, strong erosion resistance application condition solutions.

Other series Products

For the long working life, high efficiency products what we produce are tundish zirconia nozzle insert,EAF,ladle and converter slag-stopping embedded the zirconia slide gate, zirconia ring, super-long-working-life of zirconia atomizing nozzle, artificial crystal (Sapphire, laser sapphire, etc.) growing equipment rare-earth composite oxide SS ceramic thermal field, etc.series products. The product's quality is equal to, even higher than the ones made in EU, USA, and favorable price, obviously working effects.
