Abstract: A hydraulic system with a high-pressure pumping state and a low-pressure pumping state. The hydraulic system comprises: a first hydraulic cylinder (210) and a second hydraulic cylinder (220), the first hydraulic cylinder (210) and the second hydraulic cylinder (220) being both provided with a non-rod chamber (211, 221) and a rod end chamber (212, 222); a switch valve; and a first channel placed between the non-rod chamber (211) of the first hydraulic cylinder and the non-rod chamber (221) of the second hydraulic cylinder. The switch valve controls the connection/disconnection of the first channel. The hydraulic system further comprises a second channel in parallel connection with the first channel and placed between the non-rod chamber (211) of the first hydraulic cylinder and the non-rod chamber (221) of the second hydraulic cylinder, wherein the switch valve controls the second channel to connect during the low-pressure pumping state and disconnect during the high-pressure pumping state. In the case of low-pressure pumping, the non-rod chambers of two hydraulic cylinders can be in communication with each other through either the first channel or the second channel. Thus the flow capability between the non-rod chambers of the two hydraulic cylinders is improved and pipe explosion is prevented, thereby ensuring the reliable cutoff or communication between the non-rod chambers of the two hydraulic cylinders in the case of high-pressure pumping, reduce system impact, and increase system reliability.

Title: Pre-control method of head and tail shapes of continuous casting slab for reducing the removed amount from the head and tail of hot-rolled intermediate slab
Inventor: SHAN XUYI
IPC: B22D11/126
Filed: 2012-03-14
Abstract: A pre-control method of head and tail shapes of continuous casting slab for reducing the removed amount from the head and tail of hot-rolled intermediate slab. By a pre-control cutting process for the head and tail shapes of continuous casting slab, the slab is cut into a shape such that its head end surface dents inwards and its tail end surface extrudes towards outside of the slab. In the pre-control cutting process, the head and tail shapes of the slab is cut in accordance with the curve which is linearly symmetrical with respect to the width center of the slab, and the arch height (i.e., the maximum value of the denting portion of the head or the extruding portion of the tail) is controlled in the range of 0 mm to 50 mm. In such a manner, the length of the non-uniform deformation portions of the head and tail of the intermediate slab can be significantly reduced, and thus the reduction of the removed amount from the head and tail of hot-rolled intermediate slab is achieved.
