Embodiment 1
[0042] This embodiment provides a method for diagnosing faults in the segment of the tensioning and leveling machine. The above faults in the segment of the tensioning and leveling machine include lifting failures in the oil cylinder. Electric control box and remote upper computer, and check whether the pressure of the hydraulic system of the sector is sufficient. When the pressure of the electric control box, remote upper computer and hydraulic system are normal, check whether the working voltage in the electric control box is normal working voltage, It is worth noting that the normal working voltage is 24V, and check whether the relays in the electric control box and the corresponding insurance are intact. The voltage in the electric control box and the relays and insurance in the electric control box are normal. When working, check whether the first connecting cable between the electric control box and the sector is connected well, and then measure whether the solenoid valve...

The invention relates to a fault diagnosis method for a fan-shaped section of a withdrawal and straightening machine, and belongs to the technical field of fault diagnosis of casting blank equipment. The diagnosis method comprises the steps that whether control equipment of the oil cylinder works normally or not is checked, the control equipment comprises an electric control box, whether the pressure of a hydraulic system of a fan-shaped section is sufficient or not is checked, and when the pressure of the electric control box, the pressure of a remote upper computer and the pressure of the hydraulic system are normal, whether the working voltage in the electric control box is 24 v or not is checked; it is checked whether each relay and fuse in the electric cabinet are intact or not; when the voltage in the electric cabinet and a relay and a fuse in the electric cabinet work normally, it is detected whether a first connecting cable between the electric cabinet and the fan-shaped section is well connected, and then it is measured whether each electromagnetic valve controlled by the electric cabinet is intact; and finally, it is detected whether a valve stand and an oil way of the fan-shaped section hydraulic system have problems or not. Through adoption of the method, an operator can quickly diagnose the reason of the lifting fault of the oil cylinder, the lifting fault of the oil cylinder is solved as soon as possible, and normal production of the fan-shaped section is recovered as soon as possible.
Description
technical field [0001] The invention belongs to the technical field of fault diagnosis of billet equipment, and in particular relates to a method for fault diagnosis of a sector segment of a stretching and straightening machine. Background technique [0002] The fan section refers to the part of the tension leveler in the slab system (14 sections in total), which is an important part of the entire slab system. Its main function is to pass the crystallized molten steel (hot billet) through each section. The pressing and driving of the main driving roll is taken out from the crystallizer and the foot roll section. In the process, through the conversion of the hot and cold billet pressure and its own characteristics and functions (continuous bending, continuous straightening and dynamic light pressing, etc.) ) to change the internal quality of the hot billet. The fan-shaped section is composed of 14 sections, which are divided into three parts: bending section (1-6 sections), ...
