TH75490B - Method for heating steel plate and steel plate heating unit - Google Patents

Abstract

The method for heating a steel shcet that is heated to a steel plate (K) to be rolled prior to forming by hot rolling consists of: Putting the steel plate into the furnace (10) containing the heater (15) on the outer surface of the furnace in the state in which the steel plate is The supports are held in a vertical direction, while the unnecessary parts of the steel plate are not important. After forming it is firmly supported by a support part (30); And the act of giving Heated to a specified temperature in the furnace Followed by removing the steel sheet from the furnace And after Cutting and eliminating unnecessary parts before forming by hot rolling or during hot rolling forming:

Claims (8)

1. Method for heating a steel plate (steel shcet) to heat the steel plate at It must be rolled before forming by hot rolling. Method for heating the composite steel plate: The introduction of the steel plate into the furnace containing the heater on the outer surface of the A furnace in a condition in which the steel plate is supported in a vertical direction While the unnecessary part of The insignificant steel plate after forming is firmly supported by the support; And the operation of heating at a specified temperature in the furnace This is followed by removing the griddle from the furnace and after that the removal of unnecessary parts. 2. The method of heating the steel plate according to claim 1, where the steel plate is moved in a vertical direction in the furnace. 3. Method for heating the steel plate according to claim 1 or 2, where the tensile force is given to the steel plate that is firmly supported. 4. A set of heaters for steel plates to heat the steel plate to be rolled. Before forming by hot rolling A set of steel plate heaters that include: a furnace capable of loading steel plates in a vertical state; And a set of conveyors that make the steel plate pass the conveyor path of the furnace in the condition of being Supported in a vertical direction by the support part Where the furnace consists of a conveyor path of the steel plates being built between the facing side walls and the supplied heaters on at least one side wall surface and heating the sheet steel, and where The conveying unit consists of a support element that supports a steel plate while the support The unnecessary portion of the steel plate is insignificant after dense molding and the moving mechanisms that move the support along the rails arranged from over the origin side of the accessway. Over the destination bank of the furnace exit 5. A set of heaters for steel plates according to claim 4, which is added as well. A vertical drive mechanism that moves the support element in a vertical direction. 6. A set of heaters for steel plates according to claim 4, which is added as well. Machining mechanism that cuts unnecessary parts on the end side of the furnace exit. 7.A set of heaters for steel plates according to claim 5, which is also added. Machining mechanism that cuts unnecessary parts on the end side of the furnace exit. 8. A set of heaters for steel plates according to any of Claims 4 through 7, which is supplemented by a mechanism that provides tension to the steel plate firmly supported.
