Description

TECHNICAL FIELD

[0001] The utility model belongs to stainless steel hot rolling technical field, especially relates to a stainless steel hot continuous rolling device based on transmission stability. BACKGROUND

[0002] Stainless steel material has excellent corrosion resistance, formability, compatibility and toughness in a wide temperature range and other series of characteristics, so it is widely used in heavy industry, light industry, household goods industry and building decoration industry, etc. The stainless steel plate rolling production process includes slab feeding, slab heating, rough rolling, hot coiling box coiling / uncoiling, flying shear cutting head and tail, finishing rolling, cooling, coiling, etc. The above steps are carried out under the transmission of the transmission mechanism to the stainless steel plate. The stainless steel plate needs to be kept stable during the transmission process, so stable and safe transmission is the basis for realizing the above production steps.

[0003] In the above process steps, hot coiling box coiling / uncoiling and flying shear cutting head and tail are important equipment for replacing the head and tail of the stainless steel plate during the transmission process. After the head and tail replacement is completed, the irregular part of the stainless steel plate at the tail needs to be cut off, so if the stainless steel plate can be stabilized accordingly in this step, the cutting can be completed smoothly.

[0004] After searching, the existing technology with publication number CN218611017U is a 309S stainless steel wide band hot continuous rolling device, which includes a heating furnace, a heat preservation device, a rough rolling mechanism, a finishing rolling mechanism and a coiling mechanism. From the beginning to the end of the production line, the heating furnace, the heat preservation device, the rough rolling mechanism, the finishing rolling mechanism and the coiling mechanism are connected in sequence through the transfer line. The heat preservation device includes a box, an inert gas conveying mechanism, an inlet, a sealing mechanism, a scraping mechanism, a fixing mechanism, an outlet, a conveying roller and a heat preservation layer. The inlet and the outlet are located at both ends of the box, and the conveying roller is connected to the side wall of the box. The general process route of the stainless steel plate hot continuous rolling is provided.

[0005] Further search shows that the existing technology with publication number CN219025401U is a stainless steel plate hot rolling equipment. The driving motor drives the stud to rotate through the transmission assembly, so that the connecting frame hot rolling roller moves to adjust the distance between the hot rolling roller and the supporting roller. According to the width of the stainless steel plate, the servo motor drives the connecting plate and the placing plate to move through the moving assembly to adjust the distance between the two placing plates, so as to conveniently hot roll the stainless steel plates of different thicknesses and conveniently cut the stainless steel plates of different widths, so that the stainless steel plate hot rolling equipment is more convenient to use.

[0006] However, the technical scheme has obvious disadvantages in the process of supporting or conveying the stainless steel plate. Although the placing plate can adjust the interval to adapt to the width of the stainless steel plate, the placing plate itself is strip-shaped, and there is no structure for supporting the stainless steel plate between the two placing plates. Compared with the width of the stainless steel plate, the placing plate realizes linear support, so it is difficult to realize stable support when supporting the stainless steel plate. If the placing plate is adjusted in interval to support both sides of the stainless steel plate, the middle part of the stainless steel plate will sag or even fall due to gravity. If the placing plate supports the middle part of the stainless steel plate relatively concentratedly, there is a risk that the whole stainless steel plate will be pulled to one side and fall due to the sagging of both sides. The stable effect of the stainless steel plate cannot be realized. SUMMARY
