Description

Anti-emulsion dripping device for oil injection plate of Sendzimir rolling mill

technical field

The utility model relates to a steel rolling machine, in particular to an anti-emulsion dripping device for an oil injection plate of a Sendzimir rolling mill.

Background technique

The lubrication and cooling system of Sendzimir rolling mill includes the lubrication and cooling of rolling mill process and the lubrication and cooling of backup roll bearings. Lubrication and cooling of rolling mill process The emulsion is evenly and stably sprayed to the deformation area of the work roll and the steel strip through the oil spray nozzles of the upper oil spray plate and the lower oil spray plate to realize the lubrication and cooling of the work roll and steel strip; the backup roll Lubrication and cooling of the bearings is achieved by means of an emulsion that is passed to the mandrel of the back-up roll. For some steel types that require relatively high temperature rolling, under the premise of ensuring the lubrication and cooling of the deformed area, try to keep the steel strip after the work rolls from contacting excess emulsion, so as to increase the temperature of the steel strip. However, since the emulsion used for lubricating the upper back-up roll drips onto the upper oil spray plate, the emulsion flows downstream to the steel strip through the front edge of the upper oil spray plate, the edges and the bottom of both sides, resulting in uneven cooling of the steel strip and rolling If the processing temperature cannot be raised, the high temperature requirements during rolling of certain steel types cannot be guaranteed, which further leads to the decline in the performance of the steel types and the poor shape of the steel strip.

Utility model content

The purpose of this utility model is to overcome the above-mentioned deficiencies, by improving the structure of the upper oil spray plate, to prevent the emulsion after the lubrication and cooling of the upper support roller from dripping on the oil spray plate, and then dripping from the front and both sides of the oil spray plate to the steel strip, thereby improving the performance and shape quality of the steel plate.

The technical scheme of the utility model is realized in the following way: the anti-emulsion dripping device of the oil injection plate of the Sendzimir rolling mill comprises the oil injection plate body, which lies in that a water retaining device is arranged longitudinally on the side of the oil injection nozzle on the upper surface of the oil injection plate body The plate is provided with a choke rib near both sides of the lower surface of the fuel injection plate body.

Preferably, the cross section of the choke rib is circular.

Features of the utility model:

1. The additional water baffle prevents the emulsion from dripping from the front of the oil injection plate to the steel belt, changes the flow direction of the emulsion, and makes all the emulsion drip from both sides of the oil injection plate; while in the oil injection The choke ribs installed near the two sides of the bottom of the plate make the emulsion dripping on both sides drip directly from the edges on both sides, which can prevent the emulsion from flowing back to the middle area of the lower surface along the bottom of the two sides of the oil spray plate and dripping onto the steel belt.

2. The cross-section of the choke rib is circular, which is more conducive to the direct dripping of the emulsion from the edges on both sides.

3. The utility model is simple and easy to realize on the basis of the original fuel injection plate body, and has obvious anti-emulsion dripping effect, which ensures the performance and shape quality of the steel strip.

Detailed ways

Further describe below in conjunction with accompanying drawing:

As shown in Figure 1, in the lubricating and cooling system of the Sendzimir rolling mill, the upper oil spray plate 2 and the lower oil spray plate 3 spray the emulsion evenly and stably to the deformation area of the work roll 4 and the steel strip 5 to realize the cooling of the work roll. 4 and the lubrication and cooling of the steel belt 5. However, since the emulsion used for lubricating the support roller 1 drops onto the upper oil spray plate 2, the structure of the oil spray plate 2 in the prior art allows the emulsion to pass through the front edge of the upper oil spray plate 2, the edges and the bottom of both sides and the bottom. On the steel strip 5, the cooling of the steel strip 5 is not uniform, the rolling temperature cannot be raised, and the high temperature requirement during rolling of some steel types cannot be guaranteed, which further leads to a decline in the performance of the steel type and poor shape of the steel strip.

Fig. 2 is a schematic diagram of the structure of the upper fuel injection plate 2 of the present invention, including the fuel injection plate body 2-1, and a water barrier 2-2 is welded longitudinally on the side of the fuel injection nozzle 2-2 on the upper surface of the fuel injection plate body 2-1 3. A flow blocking rib 2-4 with a circular cross section is welded near both sides of the lower surface of the fuel injection plate body 2-1. The added water baffle 2-3 prevents the emulsion from dripping from the front edge of the oil injection plate to the steel belt, changes the flow direction of the emulsion, and makes all the emulsion drip from both sides of the oil injection plate; The choke ribs 2-4 welded near the two sides of the bottom of the oil plate make the dripping emulsion on both sides drip directly from the edges on both sides, which can prevent the emulsion from flowing back to the middle of the lower surface along the bottom of both sides of the oil injection plate area, dripping onto the steel belt.
