Title:
EVALUATING APPARATUS FOR CORROSION RESISTANCE OF REFRACTORY MATERIAL
Document Type and Number:
Japanese Patent JP2809572
Kind Code:
B2
Abstract:
PURPOSE: To evaluate the corrosion resistance of refractory material in the state very close to the actual using state under atmosphere without introducing inactive gas when the refractory material is submerged and to improve the reliability by cooling the refractory material from the inside when the refractory material is submerged into slug.
CONSTITUTION: Slug 1 is inputted into a graphite crucible 4. The graphite crucible 4 is heated with a high-frequency induction heating coil 7, and the slug 1 is fused. A refractory material 10, which is supported with a holder 9, is submerged. A motor 28 is driven, and the refractory material 10 is rotated around the axial core thereof. The refractory material 10 is cooled : from the inside when the refractory material is submerged into the fused slug 1.
