Zirconia Slide Gate Plate Embedded in Al2O3 body in ladle 4-6 slide times continuously, Fangming Zirconia-China Lead Manufacture
Requirment about the Slide Gate Plate in Ladle
In the normal flowing controlling conditions, The slide gate plate is very easy be thermally attacked by the molten steel at high temperature and worn down of sliding surface.
Under the harsh conditions, in order to ensure the safety, reliability and high service life of the slide gate plate, the slide gate plate (as functional refractories) for continuous casting is desired to own the high thermal shock resistance, spalling resistance, erossion resistance, and corresponding structural characteristics, etc.
In order to smelt clean and pure steel, it is necessary to research and develop the slide gate plate (flow control refractory) with purifying function for molten steel. Zirconia has the inactive chemical properties at high temperature, and do not active with the smelt steel liquid and slag, so it is the best choice to choose the zirconia material as the refractory material touched the steel liquid directly.
Alumina with the graphite series of material slide gate plate, such as Alumina-Carbon, Alumina-Zirconia-Carbon,Magnesia-Carbon.etc. has the low sliding times, usually 1 or 2 times. Comparing to them, Embedded our zirconia sliding gate plate in the alumina body in ladle of steel plant can sharply increase the working life of the whole slide gate plate, and it can reach the -4-6 slide times continuously, even higher.
Production Process
Our zirconia Slide gate plate is made of the high quality of zirconia grain and powder, part stabilizer, through the the fully mixing, inspecting, drying, pressing, inspecting, sintering, Inspecting, Polishing Inspecting, packing series process, then deliver from our factory.
Products Features
Our Zirconia Slide Gate Plate 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.

Fangming NewM Introduction
Fangming NewM is setup in Sep.,2015. We are one high-new technology enterprise of producing the high purity and ultra-high temperature new type of the composite nano-ceramic materials and products based on the zirconia (Zirconia Slide Gate Plate ), and urgently much needed to breakthrough key technologies in the new materials category advocated and developed by the state in the 2025 planning catalogue, the High-New Technology manufacturer of the rare composite new materials of the super high temperature structural ceramics, which are applied in the extreme environments.
Up to now it is also the most professional manufacturer of ultra-high temperature rare earth oxide composite ceramic material and products in Henan Province, even in the whole country with the highest automation and the largest production capacity.
Now we have gained the ISO9001:2015, ISO14001:2015, OHSAS18001:2007,ISO50001:2011, etc. Certificates.We have owned the 8 related invention patents and utility model patents.
