Low density of the zirconia nozzle as flow control refractory in the tundish to smelt special steel products

Products Features:

Our low density of the zirconia nozzle inserts as flow controlling of steel liquid and slag refractory in the tundish widely used in the large capacity of tundish in steel plant. It has the better quality quality, longer working life than our normal 5.4g/cm3 one, after embedded in the alumina or corundum quality body, can be used in the sliding system of ladle and tundish directly, do not desired to heat before using. Especially used for smelting the special high grade steel types, such as low carton steel, alloy steel etc.

Production Process

Our low density of the zirconia nozzle insert as flow control refractory is made of the high quality of e-fuzed magnesia and zirconia grain and sand, bonding agent, through the the automatic system mixing, drying, pressing, inspecting, sintering, etc. series system process, then pack into the carton, and wooden box with the desired shipping mark sticked, then deliver to the china mainland and oversea from our factory.

Inspection times in production process

1. After Mixing, inspect the water content of material,

2. After pressing, inspect the size,missing angle, etc. of semi-finished products

3. After sintering, inspect the size, missing angle, cave, etc. of finished products

4. Before packing, inspect the size, missing angle, cave,of the finished prodcuts again.

Chemical Composition and Physical Propeties

Size Tolerance:

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

Exported Countries

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

Fangming NewM's Goal

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.

Example for actual working conditions

Zhengzhou Fangming High Temperature Ceramic New Material Co., Ltd. Lies in Xinmi City, Henan, China. It covers over 20000 sm2.

Setup in Sep. 2015, Fangming NewM is one High-New Technology Enterprise, manufacturing the high-purity and ultra-high-temp. new type of composite nano-ceramic materials and products as the zirconia basic material, and the one of the urgently to be solved and breakthrough key technologies in the new materials category advocated and developed by the state in the 2025 planning catalogue, the one of the rare composite new materials of the super high-temp. structural ceramics, applied in the extreme environments. We has obtained the ISO 9001:2015 quality management, ISO 14001:2015 environmental management and OHSAS 18001:2007 occupational health and safety management system, the energy efficiency management system, etc. series qualifications, and has owned eight patents.

Since setup, our company is devoted to the R&D, creation of the new type of composite nano-ceramic materials and products. Fangming NewM mainly produce: 1). ZrO2 Nozzle, slide plate, ZrO2 Ring, Insert, applied as flow control function in metallurgy at high-temp. State, 2). ZrO2 atomizing nozzle in the amorphous alloy powders, 3).Rare-Earth Oxide Composite SS ceramic thermal field in artificial crystal (Sapphire, laser gem, etc.) grower, 4).Pre-sintered ZrO2 parison, base plate for metal sputtering target, 5). High density ZrO2 ceramic lip brick in ultra thin electronic glass , sintering gasket in electronic device. 6). Device in hot compression equipment of 3D glass, etc. The quality of products we are producing is the same, even better than the one produced by the other producers in the same industry from USA, European countries.

Taking the modernized automatic controlled equipment, persistently carry out the digitized, standardized production and management processes, the advanced ERP and IMES management system in our country, the product’s quality and overall performance has reached even exceeded to the level of the same industry in the world.
