In the production of clean steel, as in many refractory products, continuous casting refractories are asked to meet the expectation have long-life, economical and safe flow control. Ladle slide plates which are the one of the continuous casting refractories, are materials that provide controlled steel flow from the ladle to the tundish. Therefore, the temperature strength properties of the refractories used for ladle slide plates should be given more importance since they are in first contact with hot liquid steel.

Together with the advancing technology, different steel qualities and increased capacity, the ladle slide plate contents have started to vary due to its great impact on steelmaking cost. Operating conditions (capacity, time, cost) in terms of refractory requirements for ladle slide plates are listed as follows:

a) High thermal shock resistance

b) Erosion resistance to metal slag

c) Low coefficient of thermal expansion

d) High thermal conductivity

e) Good crushing strength

f) Abrasion resistance
