Abstract
The utility model discloses an early warning device for the pressure of a roughing mill. The early warning device comprises a first pressure spring and a second pressure spring. One end of the first pressure spring and one end of the second pressure spring are respectively connected with one end of a roller bearing, and the other end of the first pressure spring and the other end of the second pressure spring are respectively fixed to a spring frame. One end, connected with the spring frame, of the first pressure spring and one end, connected with the spring frame, of the second pressure spring are connected with a first pressure sensor and a second pressure sensor respectively, the first pressure sensor and the second pressure sensor are connected through a controller, and the controller is connected with an alarm device. The early warning device is accurate in control and protects a roller effectively.
Description
Technical field
The utility model belongs to Mill Technology field, is specifically related to a kind of roughing mill pressure prior-warning device.
Background technology
When band pressure rolling, first to pass through roughing mill, roughing mill mainly completes the section of blank and depresses, the material difference of band, the wearing and tearing of pair roller and requirement are also different, and the material of band is partially hard, so just requires the toughness of roll material better, in the time exceeding the scope of roll toughness, make the roll left and right sides stressed asymmetric, cause product to occur quality problems, and damage roll.In addition, while entering finishing mill through the band of roughing, if the information of rough rolling step can be passed over, follow-up adjustment and protection finishing mill are played a very important role.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of roughing mill pressure prior-warning device is provided, and this device control is accurate, has effectively protected roll.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of roughing mill pressure prior-warning device, comprise the first compression spring and the second compression spring for measuring roll bearing both ends radial force, one end of the first compression spring and the second compression spring is connected with one end of roll bearing respectively, the other end of the first compression spring and the second compression spring is individually fixed on spring(-supported) mount, one end that the first compression spring is connected with spring(-supported) mount with the second compression spring is connected with respectively the first pressure sensor and the second pressure sensor, the first pressure sensor is connected by controller with the second pressure sensor, this controller is also connected with alarm.
Further, this first compression spring and the second compression spring are Rectangular Spring.
A kind of roughing mill pressure of the utility model prior-warning device, in the time exceeding the toughness scope of roll with the intensity of steel, can accurately provide early warning, makes roll avoid damaging; Also for adjusting parameter, finish rolling workshop section provides standard simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of roughing mill pressure of the utility model prior-warning device.
The specific embodiment
As shown in Figure 1, a kind of roughing mill pressure of the utility model prior-warning device, comprise the first compression spring 2 and the second compression spring 3 for measuring roll bearing 1 both ends radial force, one end of the first compression spring 2 and the second compression spring 3 is connected with one end of roll bearing 1 respectively, the other end of the first compression spring 2 and the second compression spring 3 is individually fixed on spring(-supported) mount, one end that the first compression spring 2 is connected with spring(-supported) mount with the second compression spring 3 is connected with respectively the first pressure sensor 4 and the second pressure sensor 5, the first pressure sensor 4 is connected by controller 6 with the second pressure sensor 5, this controller 6 is also connected with alarm 5.The first compression spring 2 and the second compression spring 3 are Rectangular Spring.
Operation principle of the present utility model is: the formula of spring stress is F=KS, and in the time entering the roll of roughing mill with steel, the stressed of the first compression spring 2 is F
1=KS
1, the stressed of the second compression spring 3 is F
2=KS
2, A=|S
1-S
2|; In controller, be preset with the number range B of an expression roll two ends balance, in the time that the numerical value of A is not in the scope at B, now warning device will give the alarm.
Claims (2)
1. a roughing mill pressure prior-warning device, it is characterized in that, comprise the first compression spring (2) and the second compression spring (3) for measuring roll bearing both ends radial force, one end of described the first compression spring (2) and the second compression spring (3) is connected with one end of roll bearing (1) respectively, the other end of described the first compression spring (2) and the second compression spring (3) is individually fixed on spring(-supported) mount, one end that described the first compression spring (2) is connected with spring(-supported) mount with the second compression spring (3) is connected with respectively the first pressure sensor (4) and the second pressure sensor (5), described the first pressure sensor (4) is connected by controller (6) with the second pressure sensor (5), described controller (6) is also connected with alarm (5).
2. according to a kind of roughing mill pressure prior-warning device claimed in claim 1, it is characterized in that, described the first compression spring (2) and the second compression spring (3) are Rectangular Spring.
