Refractory 5.50g/cm3 Sliding Lower Nozzle For Steel Continuous Casting

Refractory 5.50g/Cm3 Sliding Lower Nozzle For Steel Continuous Casting​

Lower Nozzle Features:

Lower Nozzle is an important part of continuous casting production.Molten steel flows from the tundish into the crystallizer through the tundish nozzle.In this process, the outlet hole will be eroded and widened, the amount of molten steel in unit time will increase, and the surface of molten steel in the mold will increase, so it is necessary to improve the casting speed to digest the excess molten steel.With the further abrasion and expansion of the outlet hole, the adjustment of pouring speed can not digest all the excess molten steel, but it is a waste for the steel enterprises to release the excess molten steel through the emergency outlet.

Production Process

we produced Lower Nozzle 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.

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.

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.
