At present, the steel mills and weighing machine measuring element in general use rigid connection means, which leads to the measuring components take the friction when billet drags directly, and then reduces the service life of the components; while the friction cannot transfer to the end seat, that causes the breakage of the weighing machine. Billet online weighing hydraulic system takes use of the hydraulic cylinder to hold billet up for weighing, which is able to overcome the above disadvantages, and to complete the weighing process. Billet online weighing hydraulic system is the key equipment for online automatic weighing of billet in metallurgy industry of continuous casting and rolling equipment,the performance quality of this equipment directly relate to accounting the production cost of enterprise and thus influencing the economic benefit of enterprise, the role of the hydraulic system is to combining electrical control to drive the mechanical parts. This design, through multiple-site research, complete the whole process of the design, installation and commissioning in billet online weighing hydraulic system,,and arranged them into relevant documents.
