FURNACE BODY STRUCTURAL MEMBER FOR SHAFT METALLURGICAL FURNACE

Title:

FURNACE BODY STRUCTURAL MEMBER FOR SHAFT METALLURGICAL FURNACE

Document Type and Number:

Japanese Patent JP3397113

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a furnace body structural member for a shaft metallurgical furnace capable of not only appropriately cooling the refractory on the in- furnace side but also effectively preventing its detachment due to losses.
SOLUTION: A furnace body structural member is provided with a metallic structural member 1 provided with a refrigerant flow passage inside, an in- furnace side refractory 2 arranged on a cooling operating surface of the metallic structural member, a metallic connection and support member 3 which is projected on the cooling operating surface of the metallic structural member and supports the in-furnace side refractory when inserted in a fitting notched groove 8 or a fitting hole on a back surface side of the in-furnace side refractory, and a heat insulation member to be interposed between the connection and support member and the inner surface of the fitting notched groove or the fitting hole. Generation of the heat distribution inside the refractory is prevented, and generation of damages such as cracks in the in-furnace side refractory is prevented by appropriately suppressing the cooling inside the in-furnace side refractory through the connection and support member.
