Large Size and Special Shapes of Zirconia Slide Plate for EAF Taphole Slide Plate Mechanism

Steel-Making by EAF

Nowadays Steel-Making way in the world is mainly by EAF. The smelting process is generally divided into melting period, oxidation period and reduction period. In the furnace, not only oxidation atmosphere but also reduction atmosphere can be created, so the efficiency of dephosphorization and desulfurization is very high.

Steel-Making by EAF is mostly used to produce high quality carbon structural steel, tool steel and alloy steel. This kind of steel has good quality and even performance. At the same carbon content, the strength and plasticity of Steel-Making by EAF are better than that of steel-making by open hearth way. The main raw material of steel-making by EAF is scrap of similar steel grades, and sponge iron is also used to replace some scrap. Adjust the chemical composition and alloy element content by adding ferro-alloy.

Almost all the EAF is more than 150 tons production capacity in the abroad, they are used to smelt ordinary steel, and 60-80% of the output in many countries is low carbon steel. Due to the shortage of electric power and scrap in China, it is mainly used for smelting high-quality steel and alloy steel.

Zirconia Slide Plate Features

Our Large size and special shape of Zirconia Slide Gate Plate in EAF has the high performance features, such as high purity, high density, strong erosion and scouring of steel liquid and slag resistance, excellent thermal shock stability, increasing the working life of the slide gate plate etc., Reduce the plantiful of the energy and power consumption, and raising the steel-making's speed and efficiency.

Production Process

Our Zirconia Slide Plate for EAF is made of the high purity of e-fuzed zirconia grain and powder, bonding agent, through the world advanced full automatic system fully mixing, drying, inspecting, pressing, inspecting, sintering, Inspecting, Polishing, final Inspecting, etc. series complex process, then packed into the fumigation wooden box with the client's information printed well, deliver to the china mainland and oversea from our factory.

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.
