Abstract
An improved outlet guiding device of a 1549 mm rolling mill belongs to supporting facilities of rolling mills, and comprises a lower water-cutting board 1, an upper water-cutting board 2, an upper lining board 3, a lower lining board 5, an upper guiding body 4 and a lower guiding body 6, wherein the upper water-cutting board 2 is connected with the upper guiding body 4 through a pin shaft; and the lower water-cutting board 1 is embedded in the lower guiding body 6 through a trapezoid block welded on the lower water-cutting board 1. The improved outlet guiding device is characterized in that the upper lining board 3 is a steel plate 7 with the 15*426*1555 size; and the steel plate is welded integrally with the upper guiding body 4 to form a water tank. Through the device, the cooling water overflow phenomenon is eliminated, so that the influence on a rolled steel plate due to cooling water overflow is avoided, the surface quality of the steel plate is improved, and the service life of a rear guiding device of the rolling mill is prolonged.
Description
Technical field
The utility model belongs to the auxiliary facility of milling train, is specifically related to improved 1549mm milling train outlet guide device.
Background technology
Fast because of the hot continuous rolling production line rhythm of production, rolled plate temperature high (about 1000 ℃) is when steel plate passes milling train; Guide and guards receives steel plate heat radiation baking serious behind the milling train, the upper guide plate position of guide and guards especially, be positioned at the high temperature steel plate directly over; Cause the easiest generation thermal deformation in upper guide plate place; Influence of rolled more can cause the upper guide plate solid failure when deflection is big, falls into milling train and causes great production accident.
In order to reduce temperature, adopt outside water spray cooling.Fig. 1 is the structure chart of existing milling train outlet guide device.It mainly by following water discharging board 1, go up water discharging board 2, top liner plate 3, bottom liner plate 5, go up guide and guard body 4, guide and guard body 6 constitutes down; Last water discharging board 2 is connected in guide and guard body 4 by bearing pin; Following water discharging board 1 is embedded in down in the guide and guard body 6 by the trapezoid block that is welded on the water discharging board below; Top liner plate 3 is made up of three block plates, and three block plates are fixed on through studding and last guide and guard body 4, and bottom liner plate 3 also is to fix through studding and following guide and guard body frame 6.
The milling train outlet guide device of this structure is in special steels such as production stainless steel, silicon steel are rolling, and cooling water drops on surface of steel plate in a large number, causes plate surface quality to descend, and influences the stability of steel plate rolling when serious.
Summary of the invention
Excessive to the rolled plate influence in order to eliminate cooling water, the utility model improves 1549mm milling train outlet guide device.
The utility model by following water discharging board 1, go up water discharging board 2, top liner plate 3, bottom liner plate 5, go up guide and guard body 4, guide and guard body 6 constitutes down; Last water discharging board 2 is connected in guide and guard body 4 by bearing pin; Following water discharging board 1 is embedded in down in the guide and guard body 6 by the trapezoid block that is welded on the water discharging board below; It is characterized in that top liner plate 3 is one 15 * 426 * 1555 a steel plate 7, steel plate 7 is welded as a whole with last guide and guard body 4, forms water tank.
The utility model has been eliminated the excessive phenomenon of cooling water, thereby has avoided that cooling water is excessive to have improved plate surface quality to rolled plate influence, has prolonged the service life of guide and guards behind the milling train.
The utility model make the outlet guide first half become in cold form, it is under the condition of no external refrigeration, thermal deformation no longer takes place in the upper guide plate place, can not take place to fall into milling train behind the upper guide plate solid failure and cause great production accident because of distortion causes.
Description of drawings
Fig. 1 is the structure chart of existing 1549mm milling train outlet guide device.
Fig. 2 is the partial structurtes figure (identical among other parts and Fig. 1, as to omit) among the utility model embodiment.
Among the figure, 1, following water discharging board, 2, go up water discharging board, 3, the top liner plate, 4, go up the guide and guard body, 5, the bottom liner plate, 6, guide and guard body down, 7, steel plate.
The specific embodiment
Embodiment: shown in Figure 2; Improved 1549mm milling train outlet guide device by following water discharging board 1, go up water discharging board 2, top liner plate 3, bottom liner plate 5, go up guide and guard body 4, guide and guard body 6 constitutes down; Last water discharging board 2 is connected in guide and guard body 4 by bearing pin; Following water discharging board 1 is embedded in down in the guide and guard body 6 by the trapezoid block that is welded on the water discharging board below, and top liner plate 3 is one 15 * 426 * 1555 a steel plate 7, and steel plate 7 is welded as a whole with last guide and guard body 4.
Present embodiment is that top shown in Figure 1 liner plate 3 (three blocks of stainless steel liner plates that discharge side by side) is removed; The outstanding seam mill off of the guide and guard body first half and liner plate location is become the plane; On this plane, weld 15 * 426 * 1555 steel plates 7; Make itself and last guide and guard body form casing, be used to hold cooling water, be referred to as water tank.
Claims (1)
