- thermal expansion;
- shell integrity;
The new clean steel procedures currently being developed in the steelmaking mills require the use of stiff refractory working linings in ladles, such as high-alumina and basic brick. Appropriate expansion allowance is required to avoid excessive thermal expansion stresses in the working lining and the ladle shell. Optimum expansion allowance minimizes hot metal runout, maintains the ladle shell integrity, and avoids premature deterioration of the working lining. Presented are material propertis of refractory linings, and analytical procedures which predict ladle wall stresses that compare favorably with field strain-gage data. Included are analytical comparisons of static stress/strain refractory property data with sonic or resonant elastic modulus data.
