Offset for the production of a refractory ceramic moulded body, and a use of shaped bodies formed therefrom

摘要

Offset for the production of a refractory ceramic molded body, the at least a purely magnetic surface iti component and at least one of cao - containing component in a grain size of 8 mm, and has the following oxide analysis:a) 50 to 90 w -% mgo,b) 8 to 40 w -% cao,c) 1 to 8 w -% fe₂O₃,d) up to 10 w -% other,the sum of a) to d) 100 w -% is obtained and the average grain size (d₅₀) the cao - alloy component is greater than the mean particle size (d₅₀) the magnetic component is between iti.
