Refractory bricks characteristics: in the use of metallurgical process of special functional role, often as a single element or with a few auxiliary refractory products like high alumina bricks ,clay bricks,insaluting bricks and so on combination, on the creation of a special production process, material choice and high-grade refractory materials are almost has a high performance, such as magnesium carbon materials, aluminum zirconium materials, carbon materials, just the quality of the jade zirconia quality, etc., is the cause of most of currently used functional refractory refractory material containing carbon.
Refractory bricks performance requirements: the use of functional refractory brick conditions are harsh, such as skateboarding in use through high temperature liquid steel thermal shock and curtains on the sliding surface wear: continuous casting tundish, overall stopper, submerged nozzle when cast starting liquid steel through strong thermal shock and pouring liquid slag erosion;
Vent firebrick in use through operation process under the thermal cycling effect and air agitation of liquid steel flow erosion effect and so on.With the continuous development and mature of continuous casting technology, the function of the service life of refractory material and function also have higher and higher requirements.
Therefore, to the general requirements of refractory materials: in order to ensure the safety and reliability under harsh conditions of use and high service life and function of continuous casting with refractory material with high thermal shock resistance and spalling resistance, erosion resistance and to play its functional role should have corresponding structure characteristics.
