Abstract
A distributing chute for installation in a furnace, particularly suitable for use in a bell-less charging system of a blast furnace, comprises heat-resistant ceramic tiles on its underside. These ceramic tiles are inserted between, and secured by, hollow sections which are attached to the chute body and through which a cooling medium is passed. The ceramic tiles preferably include lateral grooves; the hollow sections being fitted in the lateral grooves for securing the ceramic tiles.
Claims20
A distributing chute for a furnace comprising:
- a chute body with a top side and an underside, said top side forming a chute channel, said underside being at least partly subjected to radiant heat in the furnace;
- hollow tube sections attached to said underside of said chute body and forming a plurality of spaced apart tube sections for the flow of a cooling fluid, each of said tube sections having a shaped outer surface;
- connecting means for connecting said hollow tube sections to a cooling fluid distribution circuit;
- and
- a plurality of heat-resistant ceramic tiles positioned between, and secured by, said hollow tube sections, each of said ceramic tiles having two opposed edges shaped to engage and form a complementary fit with adjacent pairs of said hollow tube sections.
A distributing chute for a furnace comprising:
- a chute body having a top side and an underside, said top side forming a chute channel for delivery of material to a furnace, and said underside being at least partly exposed to radiant heat when in a furnace;
- flow tube means supported on and spaced from said underside of said chute body, said flow tube means forming a plurality of generally parallel spaced apart flow tube sections for the flow of a cooling fluid, each of said parallel flow tube sections having an exterior surface of predetermined contour;
- and
- a plurality of heat resistant ceramic tiles positioned between and mounted on said parallel flow tube sections, said ceramic tiles being spaced from said underside of said chute, and each of said ceramic tiles having two opposed edges shaped complementarily to said predetermined contour of said flow tube sections to form a complementary fit with adjacent pairs of said parallel flow tube sections.
