Background technology
The hydraulic control system more complicated of existing slide runner of continuous casting ladle switch, fault rate is higher, is difficult to investigation after breaking down, and the processing time is longer.And the rear excessive major accident of molten steel that easily causes that breaks down, production brings very large harm to continuous casting.
Simultaneously, bale panoramic tables is in rotary course, and there is automatic closing function at the mouth of a river, like this between ladle upper nozzle and upper slide during badly bleeding, if close slide gate nozzle, the molten steel side spray is spattered the equipment that may cause and personnel's heavy losses, and such major accident just once occured in domestic large-scale steel mill.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of hydraulic control system for the slide runner of continuous casting ladle switch for problems of the prior art, its objective is the fault rate that reduces control system, shorten fault handling time, avoid the generation of the major accident that causes due to functional fault.
Technical scheme of the present invention is that hydraulic control system that this kind is used for the slide runner of continuous casting ladle switch comprises pumping plant, accumulator, slide gate nozzle hydraulic cylinder, manual anxious hydraulic control valve platform, autocontrol valve group and the safety valve group of stopping; Described accumulator is arranged on the safety valve group, and accumulator is the necessary energy of system's deposit, in time in the situation that the hydraulic power unit dead electricity also can guarantee to close the needed hydraulic oil in the movable mouth of a river; Described manual urgency is stopped the hydraulic control valve platform and is comprised of two hydraulic control one-way valves and a hand-operated three-position; Described autocontrol valve group is comprised of two throttle grverning valves, two hydraulic control one-way valves and two three position four-way directional control valves; Hydraulic oil is controlled the action of slide gate nozzle hydraulic cylinder by the autocontrol valve group, manually suddenly stop the hydraulic control valve platform and the autocontrol valve group is connected in parallel in system, in case of emergency is used for controlling the action of the hydraulic cylinder at the mouth of a river.
Action speed by the throttle grverning valve regulation slide gate nozzle hydraulic cylinder in the autocontrol valve group.
Described manual urgency is stopped the hydraulic control valve platform and is adopted mechanical caging, and assurance can only shutoff operation.
It is bidirectional operation when debugging that described manual urgency is stopped the hydraulic control valve platform.
The hand-operated three-position handle place that described manual urgency is stopped the hydraulic control valve platform is provided with latch, the bidirectional-movement of restriction handle, in case of emergency need not extract latch, only need get final product to direction of arrow action in Fig. 2, assurance can only one-way operation, close the mouth of a river, only can extract latch when debugging mode.
The hydraulic control system that this kind with said structure is used for the slide runner of continuous casting ladle switch has the following advantages:
1. this kind is provided with separately accumulator for the hydraulic control system of slide runner of continuous casting ladle switch, guarantees at hydraulic cylinder stable action and emergency supply; The slide gate nozzle hydraulic control system is transformed, realized by one group of autocontrol valve group in control, fault is low, is convenient to investigation; This valve group can be regulated hydraulic cylinder speed, has the hydraulic locking function; In programme-control, control system is optimized, layout again changes the hydraulic control of other each function into electrical equipment control, improves the stability of a system.
2. this kind is stopped hydraulic control valve platform employing mechanical caging for the manual urgency of the hydraulic control system of slide runner of continuous casting ladle switch, be merely able to shutoff operation, guarantee that operating personnel can in time close ladle slide gate in billet where necessary, can bidirectional operation when only having debugging.
