Abstract
The invention discloses a steel rolling water-penetrating system water tank control method and device. The method includes: detecting real-time current signals of a finishing mill; judging whether the finishing mill is in a steel biting state or a tail shedding state or not according to the real-time current signals; if yes, controlling water valves of water tanks to be sequentially opened or closed according to a preset water tank sequence. By applying the steel rolling water-penetrating system water tank control method and device, signals controlling the water tanks are changed from original hot metal detector signals to real-time current information of the finishing mill, the problem of steel heaping caused by impact on rolled pieces due to the fact that water penetrating valves are frequently opened and closed or not closed because of unstable signals originally is avoided, and the water tanks can be controlled to be accurately closed; memory temperature control is performed on heads and tails of the rolled pieces, so that the problem that the heads and the tails of the rolled pieces are unqualified in physical performance is avoided, production cost is lowered, and rolling yield is increased.
Description
Technical field
The present invention relates to Rolling production control technology field, more particularly, it relates to water system water tank control is worn in a kind of steel rolling
Method and device processed.
Background technology
Fine-grained steel is that metal material makes its inherent grain size reach 5 to 8 grades by some heat treatment method crystal grain thinnings,
Thus improving the steel of its mechanical performance.In the middle of the trial production process of fine grain variety steel exploitation, one side Chang Yin wears water system
System causes impact in boiled water moment to the rolled piece in guide groove, leads to rolled piece to bent in guide groove or in finishing mill, reducing sizing mill
Break and cause piling of steel；On the other hand it is the thermometal detector jitter because wearing water system, lead to wear water valve frequently switching on
Water or do not close, causes the impact to rolled piece to cause piling of steel.
Existing using four thermometal detectors to judge rolling line whether have rolled piece to pass through and to water tank work control, essence
Milling train enters, export each install one and control 1#2# water tank simultaneously, reducing sizing mill enters, export and each install a control 3#4# water simultaneously
Case.Because in-situ production environment water smoke is big, often cause thermometal detector signal to flash, cause water tank to pass through period in rolled piece frequent
Switch water valve and when rolling line no rolled piece water valve cannot close, open, cause next rolled piece to roll by steel stifled during water tank, whole piece
Part performance is unqualified.Keep wearing water system long period steady operation, it is necessary to assure four thermometal detector signals are reliable, letter
Number unstable water tank logic control program will be caused to malfunction.And thermometal detector signal is easily subject to external environmental interference, body
Also fragile.

The embodiment of the invention discloses water system water tank control method and device are worn in a kind of steel rolling, water valve is worn with solution frequent
Switch water or do not close, cause the impact to rolled piece to cause the problem of piling of steel.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation description is it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of not making creative work
Embodiment, broadly falls into the scope of protection of the invention.
Water system water tank control method is worn in a kind of steel rolling that the present invention provides, and wherein, finishing mill and water tank communicate to connect, its
In, it may include multiple water tanks are connected with finishing mill.
Refer to shown in Fig. 1, be the flow process signal that water system water tank control method is worn in steel rolling provided in an embodiment of the present invention
Figure, the method comprises the following steps:
S11: the real-time current signal of detection finishing mill；
S12: judge whether finishing mill is according to described real-time current signal and sting steel state or de- shape of tail state；
General, when finishing mill is in and stings steel state, electric current produces rising edge pulse signal, when finishing mill is in de- tail
During state, electric current produces trailing edge pulse signal, by detecting the real-time current signal of finishing mill, judges whether finishing mill is in
Sting steel state or de- shape of tail state, execute next step s13.
S13: if so, then opened or closed successively according to the water valve of default water tank sequential control water tank.
If finishing mill is in steel state of stinging, controls the water valve of water tank to open successively, rolled piece is processed, if at finishing mill
In de- shape of tail state, then the water valve of water tank is controlled to close successively.Specifically, water tank may generally be 4, the first water tank and the second water tank
Can be separately mounted to the entrance and exit of finishing mill, three-tank and the 4th water tank can be separately mounted to reducing sizing mill entrance and
Outlet, certainly, in other embodiments it is also possible to the water tank of setting other quantity, may be provided at corresponding position as needed,
The quantity and set location of specific water tank is not construed as limiting, as long as identical technical purpose can be reached.
