Embodiment Construction
[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0022] Such as figure 1 As shown, the system embodiment includes a working platform 1, a reference rod 2, a working rod 3, a billet edge heater 4, sensors, motors and other components not shown in the figure. The working platform 1 is located on one side of the transport roller table 6 for conveying steel billets 5 such as steel coils, plates and strips, and the reference rod 2 and the working rod 3 are installed on the working platform 1 . In actual application, there can be one or more working platforms 1 , and multiple working platforms can be arranged on both sides or one side of the conveying roller table 6 . On each working platform 1, the number of reference rods 2 for detecting the offset of the steel billet 5 and the number of working rods 3 for installing the billet edge heater 4 in the edge area of the steel billet 5 can...

The invention provides a billet steel edge heating system and a billet steel edge heating method. The system comprises a position detector, a billet steel edge heater and a heater support device, wherein the position detector is arranged on a billet steel conveying roller way or at one side of the billet steel conveying roller way and is used for detecting the position of the billet steel edge in real time; the billet steel edge heater is used for locally heating the billet steel edge region; the billet steel edge heater is mounted on the heater support device which is arranged at one side of the billet steel conveying roller way and is used for moving the billet steel edge heater to the billet steel edge in real time to be connected with the position detector so as to obtain the position data of the billet steel edge, and the billet steel edge heater is thus moved to the billet steel edge region. The billet steel edge heating system and the billet steel edge heating method are particularly suitable for heating the edges of billet steel such as steel coils, plates and strips, the edge heating regions of different plates and strips with different sizes at different positions in the conveying roller way can be precisely controlled, and the problem that the heating regions are not stable, caused by the position offset of the billet steel is avoided.
Description
technical field [0001] The invention relates to the technical field of metal forming, in particular, the invention particularly relates to a billet edge heating system and method. Background technique [0002] During the hot rolling process of steel coils, plates and strips, the temperature of the intermediate billet gradually decreases. The closer to the edge of the intermediate billet, the stronger the three-dimensional heat dissipation effect, the greater the temperature difference between the edge and the center of the intermediate billet, and even lead to Edge cracking during rolling. In the finishing rolling process, the excessive temperature drop at the edge will bring various complicated effects, such as reducing the mechanical properties of the edge of low carbon steel and microalloyed steel, increasing the rolling force required for the edge, resulting in surface defects , roll edge wear, difficulty in precise thickness control, etc. When heat treatment operation...
