Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the field of plate blank production and processing, and particularly relates to a plate blank heating furnace steel loading positioning visual identification alarm control system. BACKGROUND
[0002] The hot rolling steel heating furnace is mainly used for heating the plate blank to a certain temperature to change the internal organization performance, improve the plasticity of the plate blank and reduce the deformation resistance, so as to facilitate subsequent rolling processing. The plate blank usually needs to go through the following processes after completing the heating process:
[0003] Plate blank transfer process on the roller way: the plate blank from the upstream process is transferred for a distance on the furnace loading roller way before loading, and reaches the pre-set furnace door position of the heating furnace. During the transportation of the plate blank in the distance, the operator needs to frequently observe the position information of the plate blank, including whether the transfer is normal, whether there is deviation out of the roller way, and even whether the equipment is damaged.
[0004] Furnace front positioning: the plate blank is transferred to the furnace front of the heating furnace through the furnace loading roller way, is stopped at the position of the plate blank relative to the heating furnace according to the material distribution information issued by the computer, completes the positioning, and the manual confirmation is performed after the steel loading.
[0005] Steel loading process: the plate blank waits for loading on the furnace loading roller way after positioning, and the steel loading machine pushes the plate blank after the furnace loading space is released, the furnace door is lifted to the upper position, and the plate blank is lifted by the steel loading machine and is sent to the furnace. The manual confirmation is needed during the steel loading to determine whether there is a risk of hitting the furnace wall, and the manual confirmation is needed after the steel loading to determine whether the plate blank is stacked in the furnace.
[0006] During the steel loading positioning process, the operator needs to observe at any time. Since the operator generally needs to consider other production operations of the heating furnace, the real-time observation of each steel cannot be achieved. Once an abnormal situation occurs in the plate blank transportation process, for example, the positioning is inaccurate, the plate blank hits the furnace wall, the plate blank falls, and the plate blank is skewed, the operator cannot discover the problem in the first time and take measures, which will seriously affect the production and directly lead to the interruption of production. INVENTION CONTENTS
[0007] The technical problem to be solved by the utility model is that once an abnormal situation occurs in the plate blank transportation process, for example, the positioning is inaccurate, the plate blank hits the furnace wall, the plate blank falls, and the plate blank is skewed, the operator cannot discover the problem in the first time and take measures, which will seriously affect the production and directly lead to the interruption of production.
[0008] To solve the above problems, the technical scheme adopted by the utility model is as follows: the utility model discloses a billet heating furnace steel charging positioning visual identification alarm control system, which comprises a camera A, a camera B and a computer A, the camera A is installed on one side of the furnace charging roller, the camera B is installed on one side of the furnace charging roller and is parallel to the camera A, the computer A is installed on one side of the camera B, and the computer A is electrically connected with the camera A and the camera B.
[0009] Further, it further comprises a camera C, which is installed on the side of the furnace charging roller and is electrically connected with the computer A.
[0010] The utility model adopts the above-mentioned structure and achieves the following beneficial effects:
[0011] By monitoring the steel charging positioning process in real time, timely alarm and interlocking measures are taken after discovering the fault in the first time, which can effectively eliminate the fault time caused by the steel charging positioning problem, ensure the production continuity and stability, effectively reduce the labor intensity of the operator, eliminate the manual confirmation step, improve the work efficiency and reduce the cost.
