The present invention relates to a continuous annealing in which an element hanger brick for hanging an electric heater element is fixed to a fibrous refractory block used for a furnace wall of a continuous annealing furnace formed by folding a blanket of a fibrous refractory material. In the fiber refractory block of the furnace, in the fiber refractory block inside the furnace hanger brick inside the furnace and outside the furnace, and in a position to prevent the element hanger brick from drooping, the fiber refractory block is parallel to the furnace wall and horizontally. A pair of support rods are arranged at intervals through the fiber refractory material block, the support rods inside the furnace are arranged at positions where the element hanger bricks are supported on the lower surface of the element hanger bricks, and the support rods outside the furnace are arranged Place on the top of the element hanger bricks in a position to prevent upward movement of the element hanger bricks Characterized in that it is.

本発明では、ヒータハンガーれんがが繊維質耐火材ブロック内で炉内側と炉外側で繊維質耐火材ブロックに水平方向に突き通した一対の支持棒で支持され、ヒータハンガーれんがの前垂れ量を抑えて安定して固定できるので、鋼板製の保護板とヒータエレメントが接触し、漏電する恐れがない。   In the present invention, the heater hanger brick is supported by a pair of support rods that penetrate the fiber refractory block horizontally inside and outside the furnace in the fiber refractory block, and the amount of sag of the heater hanger brick is suppressed. Since it can be fixed stably, there is no risk of leakage due to contact between the steel plate protection plate and the heater element.
