High Density Upper Nozzle , Zirconia Insert 20-45 Hrs Continuously Working Time

Product Specification

             High density of zirconia incert for Upper nozzle of tundish- working for 20-45 hrs continuously 

Products Features:

Our irconia Insert for upper nozzle of tundish have the high density, very high strength, excellent scuring and erossion of the steel liquid and  resistance, erosion of the steel liquid and slag resistance, strong thermal shock stabilities, enlong the working life of the whole tundish upper nozzle.

Working hours of the Zirconia insert for tundish upper nozzle

For the working hours of our zirconia insert  used in the tundish upper nozzle, based on the different steel types filled in tundish, different casting times of the tundish, different qualities of the tundish nozzle, the working times of the tundish nozzle are different. Fangming NewM are producing  the requested the zirconia upper nozzle, lower nozzle, quick-changable nozzle, metering nozzles according to the clients' demand for the shape and sized, the working times has reached  20-30 hours continuously.

Production Process

Our zirconia insert for the tundish upper nozzle is taking the world's advance automatic production equipment and technology, and  take the high quality of the zirconia grain and powder, adding other additives, through the mixing, drying, inspecting, pressing, inspecting,drying, sintering,inspecting, etc. standard and system process, then produce the exact size, high quality, longer-working times of the zirconia insert for tundish upper nozzle.

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.

Usual size and size Tolerance:

We are usually producing the zirconia upper nozzle with the 75mm height, OUD:44mm and OBD: 38MM, and middle hole diameter from 12.0-20.0mm.

For the size tolerance: Middle Hole Diamter:+-0.2mm, other sizes: +-1mm.

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.
