Description

Detection device for single-side lifting of hot rough rolling plate ingot

Technical Field

The utility model relates to a detection device for single-side lifting of a hot rough rolling slab ingot.

Background

In an aluminum hot rolling system, the width variation increases as the slab thickness is reduced during hot rough rolling. In order to accurately control the width deviation, the trimming amount is reduced, and the yield is increased. The technology of precisely controlling the width of the slab ingot becomes one of important subjects of the hot rolling mill, and currently, a width control device is used as a vertical roll to precisely control the width of the slab ingot. The vertical roll control mode is position control, pressure is used as protection, and the vertical roll control mode does not participate in control. Because the calculation model of the width of the slab ingot deviates from the actual situation, the vertical roll has no edge or the clamping force is overlarge. The clamping force of the vertical rolls is overlarge, the metal temperature field at the edge of the slab ingot is unevenly distributed, the slab ingot is easily lifted up on one side, production staff does not find that continuous production and rolling are carried out, equipment is easily damaged, economic loss is generated, and raw materials are scrapped. Therefore, a set of inspection device for lifting the slab ingot on one side when the slab ingot is at the edge of the vertical roll is developed and put into use, and equipment damage and direct economic loss of raw materials are reduced.

In the embodiment of the utility model, the working principle of the detection device for single-side lifting of the hot rough rolling plate ingot is as follows:

the photoelectric sensor is used for ranging, and the maximum distance between the photoelectric sensor and the conveying roller way is H, and no slab ingot exists on the conveying roller way at the moment, as shown in figure 1. When the conveying roller way is provided with a slab ingot, the slab ingot is not lifted on one side, and in a normal state, the measurement distance from the photoelectric sensor to the upper surface of the slab ingot is h. And H can also be calculated under the default normal state, the thickness of the plate ingot in the production process is issued by the controller, H is a fixed value, and the thickness of the plate ingot subtracted from H is a theoretical calculated value H2 from the photoelectric sensor to the upper surface of the plate ingot. The roller way is provided with a slab ingot, and when the slab ingot is lifted on one side, the measuring distance between the photoelectric sensor and the upper surface of the slab ingot is h1. And comparing the value h2 with the distance h1 measured by the photoelectric sensor, and judging the system as normal if the difference is within 10 mm. If the numerical value difference exceeds 10mm, the system judges the abnormal state and outputs an alarm.
