Embodiment Construction

[0009] Below in conjunction with accompanying drawing and embodiment the present invention will be further described

[0010] A kind of hydraulic control system for COREX slag grinding system of the present invention (as attached figure 2 As shown), the control operating system is composed of electromagnetic reversing valve 1-6, motor 7 and PT1, PT2, PT3, PT4 pressure sensors; wherein, the electromagnetic reversing valve 1 is SOL1a, and the electromagnetic reversing valve 2 is SOL1b , The electromagnetic reversing valve 3 is SOL2, the electromagnetic reversing valve 4 is SOL3-1, the electromagnetic reversing valve 5 is SOL3-2, and the electromagnetic reversing valve 6 is SOL4.

[0011] According to the technological process, the present invention forms the logical relationship of different working states through the central control DCS operation, and realizes through the following steps (as attached figure 1 shown):

[0012] A. Start the hydraulic system → electrify the mot...

Abstract

The invention discloses a hydraulic control method for a COREX slag pulverizing system and relates to the technical field of hydraulic control. A control operating system consists of an electromagnetic reversing valve (1), an electromagnetic reversing valve (2), an electromagnetic reversing valve (3), an electromagnetic reversing valve (4), and electromagnetic reversing valve (5), an electromagnetic reversing valve (6), an electromotor (7), a PT1 pressure sensor, a PT2 pressure sensor, a PT3 pressure sensor and a PT4 pressure sensor. According to the process flow, the hydraulic control method forms a logic relation of different working states through central control DCS operation, realizes a series of actions including the rising, declining, pressure maintaining of a grinding roller through controlling the switches of a plurality of the electromagnetic reversing valves, can automatically judge the needed adjustment under various operating conditions and realize the actions through controlling the electromagnetic reversing valves so as to make the whole system more intelligent. The hydraulic control method improves the prior inapplicable hydraulic control method, meets the requirement of the COREX slag pulverizing process, and has the characteristics of convenient operation, high intelligence degree and the like.

Description

technical field [0001] The invention relates to the technical field of hydraulic control, in particular to a hydraulic control method used in a COREX slag grinding system Background technique [0002] Baotian COREX slag grinding system is the first slag powder production line with an annual output of 500,000 tons in China. Due to the differences in properties and grinding difficulty between the existing water slag and COREX slag, the hydraulic control method of the existing water slag grinding system cannot be used on the COREX slag grinding system, and the original water slag powder The hydraulic control method of the mill is also too simple to meet the requirements of the COREX slag grinding process. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and propose a control method that can be applied to the COREX slag grinding system and meet the hydraulic control method requirements of...
