Abstract
System for heating the broadwise-end portions of a metal plate in conveyance. The system includes a pair of heater blocks spaced apart from each other with the conveyance line for the material located therebetween. The heater blocks each have a space to receive one of the broadwise-end portions of the material. When the material is conveyed through the system, the broadwise-end portions of the material each are allowed to pass through the space of one of the heater blocks so that they are heated by burners of the heater blocks blowing hot combustion gases against the broadwise-end surfaces of the material.
Claims7
A system for heating the broadwise-end portions of metal plate which comprises (a) a means for conveying a metal material and (b) a pair of heater blocks spaced apart from each other with a predetermined line of conveyance for the metal material extending therebetween and each adapted to heat one of the broadwise-end portions of the material and is characterized in that each said heater block includes:
- (i) a casing which is provided with a space to receive said broadwise-end portion of the material and an opening to allow said broadwise-end portion of the material to enter said space and is located in such a position as allows said broadwise-end portion of the material to pass through said space when the material is conveyed along said conveyance line;
- (ii) a burner connected to said casing for blowing high-temperature gases against the broadwise-end surface of said broadwise-end portion of the material;
- (iii) a horizontal partition means disposed directly above the upper surface of said broadwise-end portion of the material in conveyance so as to allow a portion of said high-temperature gases blown against said broadwise-end surface of the material to flow along said upper surface of broadwise-end portion of the material;
- and
- (iv) a horizontal partition means disposed directly below the lower surface of said broadwise-end portion of the material in conveyance so as to allow the other portion of said high-temperature gases blown against said broadwise-end surface of the material to flow along said lower surface of broadwise-end portion of the material.
