Embodiment Construction
[0022] The method for online measurement and adjustment of the peeling amount of the flame cleaning machine of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0023] A method for on-line measurement and adjustment of the amount of skin peeled off by a flame cleaning machine, which specifically includes the following steps:
[0024] S1, install the flame cleaning machine system in the slab cleaning process of the continuous casting production line. The flame cleaning machine system is composed of four sets of online measurement sensors, communication system, control system, alarm and data recording system, flame cleaning machine, and roller table system; The branch online measurement sensor converts the distance parameter between the surface sampling point of the slab and the frame into an electrical signal in real time, and transmits it to the control system through the communication system code branch. The contro...

An online measuring and adjusting method for the scaling amount of the casting blank of a flame cleaning machine specifically comprises the following steps that S1, a flame cleaning machine system is installed, and the flame cleaning machine system is composed of four sets of online measuring sensors, a communication system, a control system, an alarm and data recording system, the flame cleaning machine and a roller way system; S2, a casting blank surface height online detection device is installed on the rear side of each nozzle of the flame cleaning machine; S3, four-positioning data collection before cleaning; S4, four-positioning data collection after cleaning; S5, the control system calculates the length of an uncleaned area, the length of a preheating pit, the depth of the preheating pit, the peeling amount and other data of each face of the casting blank through the roller way speed; S6, alarming and recording are carried out; the faulted nozzle is displayed; S7, controlling and adjusting are carried out; and S8, slipping / blank clamping faults are alarmed and recorded. The online measuring and adjusting method has the beneficial effects that on-line measurement of the peeling amount of the flame cleaning machine is achieved, automatic feedback adjustment is achieved, and the yield of casting blanks is guaranteed.
Description
technical field [0001] The invention belongs to the field of continuous casting and metallurgical production, and in particular relates to an online measurement and adjustment method for the peeling amount of a billet by a flame cleaning machine. Background technique [0002] At present, the slab flame cleaning machine in the continuous casting metallurgical production adjusts the depth of the preheating pit, the amount of peeling, the length of the slab head pit, and checks the working status of the nozzle. The casting slab is hoisted and the four sides of the slab are independently measured. This method of equipment adjustment and measurement is time-consuming and laborious, and has low measurement accuracy, long feedback process, poor rejection rate control ability and lifting safety risks. [0003] Chinese Patent Application No. 201310280154.6 discloses a detection method, detection device and processing method for concave and convex points on the surface of a slab. The ...
