Abstract
The invention relates to an automatic control technology of hot continuous rolling winding side guide. The control method of a hot continuous rolling silicon steel head superwide winding side guide position is performed according to the following steps: (1) a position sensor is mounted above a rolling line of an inlet of a winding machine for obtaining the actual width of a hot continuous rolling silicon steel head and transferring to a control center; and (2) servo valves are mounted at the upper and lower sides of the side guide, and are connected with a hydraulic cylinder through pipelines; and the control center controls the hydraulic cylinder to drive the servo valves to open an opening of the side guide according to the obtained actual width of the hot continuous rolling silicon steel head. The control method has the following beneficial effects: the winding side guide opening position is determined according to the actual width of the silicon steel head, so that the steel waste caused by superwide actual strip steel head is prevented, the precise control of the silicon steel side guide position is realized, and excellent winding shape is guaranteed.
Description
Technical field
The present invention relates to hot continuous rolling and batch the automatic control technology led side.
Background technology
Band steel is come side from finish rolling end rack outlet lead through being batched roller-way, batch side and lead and want quick clip taut band steel, and its centering is imported coiling machine.Our factory silicon steel is wide in variety, often occurs first head problem and head width ultra-wide within silicon steel head 3m, often occurs to lead opening part and steel scrap because silicon strip steel head ultra-wide withstands on side; If but to lead aperture position presetting excessive in side, band steel is led between both sides in side and is swung, and coil of strip can be caused to occur fault, turriform etc., affect product quality.
Summary of the invention
Technical problem to be solved by this invention is: the actual strip steel head width how solved in silicon steel continuous flow procedure after roughing, finish rolling rolling is greater than the bad or steel scrap problem of the scroll that causes of band steel setting width.
The technical solution adopted in the present invention is: hot continuous rolling silicon steel head ultra-wide is batched side and led position control method, carries out in accordance with the following steps:
Step one, above coiling machine entrance roll line installation site sensor, obtain the developed width of hot continuous rolling silicon steel head, be delivered to control centre;
Step 2, side are led upper and lower both sides and are installed servo valve, and servo valve is connected by pipeline with hydraulic cylinder, and control centre is according to the developed width of the hot continuous rolling silicon steel head obtained, and hydraulic control cylinder drives servo valve opening side to lead opening.
The invention has the beneficial effects as follows: according to silicon steel head developed width, the present invention determines that batching side leads enable possition, avoid, because actual strip steel head ultra-wide causes steel scrap, realizing the accurate control that position is led in silicon steel side, and guaranteeing that scroll is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Wherein, 1, roll line, 2, position sensor, 3, finish rolling end frame, 4, side leads, 5, servo valve, 6, hydraulic cylinder.
Detailed description of the invention
As shown in Figure 1, Shanxi Taigang Stainless Steel Co., Ltd's Continuous Rolling Mill is installation site sensor (model is: 4WSE 3EE 16-1X/300B8-210K9D/V) above coiling machine entrance roll line, obtain the developed width of hot continuous rolling silicon steel head, be delivered to control centre's (Siemens SIMATIC TDC controller, 10G CPU Control Unit model: 6DD1600-0BA2); Side is led upper and lower both sides and is installed servo valve (model is: D661-4367C G45JXAA6VSX2HA), servo valve is connected by pipeline with hydraulic cylinder, control centre is according to the developed width of the hot continuous rolling silicon steel head obtained, and hydraulic control cylinder drives servo valve opening side to lead opening.
Effect is as follows:
(1) lead on the basis of position control in original side, the head ultra-wide that comes into operation is batched side and is led position control method, achieves hot continuous rolling and batches side and lead and lead position according to rolling supplied materials head developed width adaptive setting side.
(2) head ultra-wide is batched side and is led position control method, solves the steel scrap because silicon steel head ultra-wide causes, and avoids the economic loss caused because shutting down process steel scrap.
(3), after dropping into this control method, eliminating that side leads can not clamping band steel and cause scroll abnormal.
(4) by implementing this control technology, strengthening side and leading position control function, strip steel head ultra-wide can be avoided, can ensure that again clamping band steel is led in side, band steel being neatly rolled onto on reel, improve the rate of good of scroll, meet the market demand.
Claims (1)
1. hot continuous rolling silicon steel head ultra-wide is batched side and is led position control method, it is characterized in that carrying out in accordance with the following steps:
Step one, above coiling machine entrance roll line installation site sensor, obtain the developed width of hot continuous rolling silicon steel head, be delivered to control centre;
Step 2, side are led upper and lower both sides and are installed servo valve, and servo valve is connected by pipeline with hydraulic cylinder, and control centre is according to the developed width of the hot continuous rolling silicon steel head obtained, and hydraulic control cylinder drives servo valve opening side to lead opening.
