High performance of tundish nozzle with zirconia insert and alumina body- working for over 30 hours
Working conditions:
Matched with the zirconia insert, with the alumina, alumina carbon, magnesia-spinel, magnesia-alumina-carbon quality, body, using the refractory mortar bonding together, composed the full set of the tundish nozzle, used in the taohole slag stopping system of the tundish or ladle,then get the excellent working effects in China and oversea steel smelting market.
Product's Features:
Our high performance of tundish nozzle with zirconia insert and alumina body have the excellent erosion and scouring resistance to the steel liquid and slag, and have the excellent thermal shock stability, can work in the preheating and cold states normal working.
From our more than 5 years' mass using in the main steel plants in China Mainland and abroad, such as Baowu Steel, MaSteel, Tansteel, Hansteel etc.national large and medium types of the steel plant, and the smelting steel type is the normal constructural steel type, and other special steel type.
Production Process
Our zirconia tundish nozzle Insert is made of the high purity of e-fuzed zirconia grain and powder, stabilizer, bonding agent, through the world advanced full automatic system fully mixing, drying, inspecting, pressing, inspecting, sintering, Inspecting,Polishing 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.
