The hot-rolled strip mill is usually equipped with side guides in front of the coiler, which mainly serve to prevent the strip from running off before the strip enters the coiler, and which are arranged in front of the coiler, which mainly consist of horizontal sections, introduction sections, drives and synchronization shafts. The wear-resisting plates are arranged on the leading-in section and the horizontal section, and the leading-in section and the horizontal section of the side guide for installing new wear-resisting plates are quickly and integrally replaced every day or even every shift.
As shown in fig. 5, the side guide guiding section is connected with the transmission structure by a guide pin I, and the side guide horizontal section is connected with the transmission structure by a guide pin II; guide pin I and guide pin II are fixed on the transmission structure, the horizontal segment is positioned with guide pin II through the fixed slide wedge, quick replacement of guide of the horizontal segment is realized, the gap between guide frames and roller tables of different replacement is adjusted through the adjusting pad, and the transmission structure pushes the leading-in segment and the horizontal segment through the fixed pin I, II.
If the quality of the product directly influenced by the quality of the side guide state is not well controlled, particularly if the horizontal section is provided with an opening bell mouth, the rolling shape is poor, loose rolling or steel piling can be generated in severe cases, and the abrasion-resistant plate is excessively worn to cause the strip steel to be damaged all over, so that the repairing difficulty and cost of the subsequent working procedure are increased.
The main problems of the existing side guide are mainly three aspects:
1. the gap between the arc of the Wei Naimo plate and the laminar roller way is unreasonable: because the wear-resistant materials of the guide and guard guide section and the horizontal section are A3 steel, the horizontal section is replaced integrally every day even every shift, and the gap between the roller way and the wear-resistant plate is often adjusted by adding an adjusting pad after the integral replacement, the process is labor-consuming and sometimes performed in a fire cutting mode, and the reasonable gap requirement cannot be met;
the original guide and guard connection mode has the problems of easy abrasion and troublesome replacement, and under the condition of different abrasion, the elevation, the levelness and the straightness of a plurality of guide and guard frames are greatly deviated, and the guide and guard frames cannot be adjusted and can be stopped for maintenance or replacement, so that the operation is complicated;
2. the abrasion of the pin shafts and the inner holes in different guide frames is different, so that gaps between the guide frames and the unified pin shafts I/II are different, fixed inclined wedges are loosened, the guide frames are easily inclined as shown in fig. 6, and the position control is inaccurate;
3. the centering bell mouth condition often occurs in the inlet straight line section, and on-line adjustment is difficult, and the effect of direct influence causes bad rolling.
