Embodiment 1

[0017] When the billet 11 is a seamless tube billet, hot-rolled thin plate slab, medium plate slab, round steel, square steel, figure 1 It is a schematic side view of a steel billet set in a groove. figure 2 It is a schematic front view of a steel billet set in a groove. The steel billet 11 is arranged in the upper and lower opposite grooves of the guide rail 10, and the thickness direction or diameter direction of the steel billet 11 is consistent with the width direction of the groove. During the process, the steel billet 11 is heated on both sides. When the steel billet 11 is loaded into the furnace, the heating furnace is in a high-temperature state. After heating, the steel billet 11 reaches the set temperature. After being released from the furnace, the steel billet 11 is directly rolled or forged under the "zero" heat preservation state. In the figure, 10a is the upper guide rail, 10b is the groove of the upper guide rail, 12a is the upper guide rail, and 12b is the...

Embodiment 2

[0019] When the billet 11 is a large slab, image 3 It is a schematic side view of a large slab arranged in a heating furnace. Figure 4 It is a schematic front view of a large slab arranged in a heating furnace. The guide rails 10 are arranged on both sides of the heating furnace, the surface of the large slab is consistent with the forward direction, and spacers 13 are arranged at the upper and lower positions between the large slabs, and the billet moves along the guide rails 10 provided on both sides of the heating furnace under the action of external force During the moving process, the steel billet 11 is heated on both sides. When the steel billet 11 is loaded, the heating furnace is in a high-temperature state. After the heated steel billet 11 reaches the set temperature, the steel billet 11 is released from the furnace. Steel rolling or forging, the groove of the guide rail 10 is provided with a roller 14, the roller 14 can be arranged on the bottom or side of the gr...

Abstract

A billet vertical heating method belongs to the field of hot-rolled steel, including a heating furnace. The billet moves along the guide rails arranged in the upper and lower directions of the heating furnace under the action of external force. During the moving process, the billet is heated on both sides. The furnace enters steel rolling or forging under the condition of "zero" heat preservation after the steel billet comes out of the furnace at high temperature. By using the method of the present invention, energy consumption can be greatly reduced, the floor area of ​​the heating furnace can be reduced, pollution can be reduced, and heating time can be shortened. time, increase the heating rate.

Description

technical field [0001] The invention relates to a heating method, in particular to a billet vertical heating method, which belongs to the field of hot-rolled steel. Background technique [0002] Steel forming is to heat the steel billet to a high temperature for rolling and forming. For a long time, the steel billet is heated in a horizontal position, and is heated from a low temperature state. When heating, the flame can only be heated on the top of the steel billet. Heating, this heating method uses a very long heating furnace for heating, and the heating furnace itself will absorb a large amount of heat. Because it is heated on one side, the heating speed is very slow, and the design of the heating furnace is very long, and the heating furnace will emit A large amount of heat, a large amount of waste gas will be emitted during the heating process, and the environmental pollution is more serious. Although there are also seamless steel pipe billets that can be installed in ...
