The utility model has the following advantages: the service life of the mould foot roller can be greatly prolonged, nine times longer than the service life of the ordinary mould foot roller, the replacement cost of the mould foot roller is reduced, the labor intensity is reduced, and the working efficiency is increased.

Description

The oil-air lubrication crystallizer foot roll

Technical field

The utility model belongs to metallurgical production continuous casting technology field, relates in particular to a kind of crystallizer foot roll of oil-air lubrication.

Background technology

In continuous casting production process, because crystallizer foot roll for a long time at high-temperature, is worked under the high strength condition, cause crystallizer foot roll not rotate, cause strand surface scratch and internal flaw to occur, increase the cost of crystallizer foot roll.At present, still do not carry out the lubricated crystallizer foot roll of oily device in the metallurgical production continuous casting technology field in working order down.

Summary of the invention

The purpose of this utility model provides a kind of lubricated oil-air lubrication crystallizer foot roll of oily device that can carry out down in working order.The utility model technical scheme that adopts of dealing with problems is as follows: the utility model includes sufficient roller, bearing, bearing (ball) cover and sufficient roll shaft, it is characterized in that a end at sufficient roll shaft prolongs axis direction and has deep hole, vertical axial plane has straight hole, and deep hole and straight hole intersect in axle.The port of one end of foot roll shaft is an oil-in, match with the deep hole of sufficient roll shaft and to be provided with the adjusting bolt, the center of regulating bolt has through hole, be used for connecting tracheae, the front portion of regulating bolt is provided with screw thread and is used for fixing on sufficient roll shaft, the end of regulating bolt has cross through hole, and oil duct and air flue are communicated with.

The beneficial effect that the utility model is new is: can significantly improve the sufficient roller service life of crystallizer, improve 9 times service time than common crystallizer foot roller, reduce the cost of changing crystallizer foot roll, reduce labour intensity, increase work efficiency.

Description of drawings

Accompanying drawing is a structural representation of the present utility model.

Among the figure, 1, sufficient roller, 2, bearing, 3, bearing (ball) cover, 4, sufficient roll shaft, 5, deep hole, 6, straight hole, 7, oil-in, 8, regulate bolt, 9, through hole, 10, screw thread, 11, cross through hole.

The specific embodiment

With reference to accompanying drawing, the utility model includes sufficient roller 1, bearing 2, bearing (ball) cover 3 and sufficient roll shaft 4, it is characterized in that a end at sufficient roll shaft 4 prolongs axis direction and has deep hole 5, and vertical axial plane has straight hole 6, and deep hole 5 is crossing sufficient roll shaft 4 in straight hole 6.The port of one end of foot roll shaft is an oil-in 7.Match with the deep hole 5 of sufficient roll shaft 4 to be provided with and regulate bolt 8, the center of regulating bolt 8 has through hole 9, is used for connecting tracheae, the front portion of regulating bolt 8 is provided with screw thread 10, be used for fixing on sufficient roll shaft 4, the end of regulating bolt 8 has cross through hole 11, and oil duct and air flue are communicated with.

Its course of work is as follows: oil gas enters in the sufficient roll shaft 4 by oil-in 7 and through hole 9 respectively, oil gas is ejected in the space between sufficient roller 1 and the sufficient roll shaft 4 by the straight hole 6 on the sufficient roll shaft 4, prolong the space face again and be passed on the bearing 2, make continuous lubrication between bearing 2, sufficient roller 1 and the sufficient roll shaft 4.
