The present invention is described in further details with reference to the accompanying drawings and detailed description.
As shown in Figure 1 and Figure 2, the embodiment of the present invention includes driving device 1, rotating shaft assembly 2, De-scaling box 3, water pipes 8, water
Nozzle 81, tracheae 9, gas jets 91, vertical plate 11, pin shaft 16, bracket 17, steel rolling production-line pedestal 18.In order to clearer aobvious
Show that the present embodiment and rejecting mechanism 6 are non-interference, Fig. 1, Fig. 2 also show the continuous casting billet 5 produced on steel rolling production-line, use
In reject problem continuous casting billet 5 rejecting mechanism 6, collect problem continuous casting billet collecting tank 7.
Specifically, water pipe 8 extends around the swingable setting of continuous casting billet 5 in the left side, upside, right side of continuous casting billet 5.It is preferred that
Ground, as shown in Figure 3, Figure 4, water pipe 8 are in inverted U-shaped, and downside is open, are tipped upside down on continuous casting billet production line and continuous casting billet 8.It is multiple
(operating) water nozzle 81 is connected on water pipe 8, and is respectively directed to the left side, upside, right side of continuous casting billet 5, for spraying water to continuous casting billet 5.With
Water pipe 8 is identical, and tracheae 9 extends, also in inverted around the swingable setting of continuous casting billet 5 in the left side, upside, right side of continuous casting billet 5
U-shaped, it is arranged side by side with water pipe 8.Multiple gas jets 91 are connected on tracheae 9, and are respectively directed to the left side, upside, right side of continuous casting billet 5,
For to 5 jet of continuous casting billet.It is highly preferred that (operating) water nozzle 81, gas jets 91 are slightly tilted to the direction of steel billet incoming side (as schemed
4).Driving device 1 is connect with water pipe 8, tracheae 9, to drive water pipe 8, tracheae 9 to complete to swing.
In order to protect water pipe 8, tracheae 8 and nozzle thereon, the present embodiment further includes De-scaling box 3, is in inverted U-shaped knot
Structure, water pipe 8, tracheae 9, (operating) water nozzle 81, gas jets 91 are set in De-scaling box 3.Specifically, in water pipe 8, tracheae 9, water spray
Steel plate etc. is set outside mouth 81, gas jets 91, a body structure is formed, to avoid water pipe 8, tracheae 9, (operating) water nozzle 81, gas blowout
The damage such as mouth 91.
It is highly preferred that as shown in Figure 3, Figure 4, being connected between water pipe 8, tracheae 9 by vertical plate 11, vertical plate in De-scaling box 3
11 are connect with De-scaling box 3 by bolt (not shown).
Meanwhile being also convenient for the connection with driving device 1.Correspondingly, the driving device 1 of the present embodiment is a cylinder,
It can certainly be oil cylinder.As shown in Figure 1 and Figure 2, the cylinder body of driving device 1 is articulated on bracket 17, in favor of swinging up and down；
The one side of its piston rod and De-scaling box 3 is hinged by pin shaft 16, the hinged side of the piston rod of De-scaling box 3 and driving device 1
Lower part is equipped with rotating shaft assembly 2, and rotating shaft assembly 2 is fixed on pedestal 18, and is located at the side of continuous casting billet 5, in favor of de-scaling
Case 3 drives water pipe, tracheae 9 to swing around continuous casting billet 5.Since water pipe 8, tracheae 9, (operating) water nozzle 81, gas jets 91 are set to de-scaling
In case 3, therefore, when driving device 1 drives De-scaling box 3 to swing, water pipe 8, tracheae 9, (operating) water nozzle 81, gas jets 91 will therewith
It swings.
As shown in figure 5, rotating shaft assembly 2 includes: bearing block 12, bearing 13, stiffening plate 14, rotary shaft 15.Two bearings
Seat 12 is fixed on the pedestal 18 of continuous casting billet production line；Two bearings 13 are then respectively arranged in two bearing blocks 12；Rotary shaft 15
Between two bearings 13, the side hinged with the piston rod of driving device 1 of De-scaling box 3 is fixedly connected.Further, it rotates
Fixed there are two stiffening plate 14 on axis 15, De-scaling box 3 is fixed between two stiffening plates 14, and is welded with stiffening plate 14.
Again as shown in Figure 3, Figure 4, the relatively close steel billet incoming side of water pipe 8 (Fig. 4 arrow side is steel billet incoming side),
Tracheae 9 is relatively distant from steel billet incoming side.
Between the present embodiment normal production period, if the piston rod of Fig. 1, driving device 1 are in stretching state, De-scaling box 3 is in
Horizontality.Water, gas are sprayed from the (operating) water nozzle 81 of installation annular on water pipe 8, tracheae 9, gas jets 91 at an angle respectively
Out, the iron scale on continuous casting billet 5 is removed, realizes scale removal effect.Preferably, the water source connecting with water pipe 8 comes from production line
On roll cooling water, pressure is in 0.4MPa-0.5MPa, compressed air of the gas source connecting with tracheae 9 from production line, pressure
Power is 0.4MPa or so, such as 0.35MPa-0.45MPa, by the control of control valve, it can be achieved that automatic start-stop.
As shown in Fig. 2, water source, gas source are first shut off when rejecting problem continuous casting billet 5, the present embodiment stops de-scaling work.
Under electric control system controls, piston rod starts to shrink driving device 1, and the contractile motion of piston rod drives de-scaling by pin shaft 16
Case 3 and the water pipe 8 being arranged thereon, tracheae 9, (operating) water nozzle 81, gas jets 91 rotate counterclockwise around the center line of rotary shaft 15, from
The operating radius of rejecting mechanism 6 is opened, rejecting mechanism 6 rotates clockwise, and problem continuous casting billet 5 is rejected to collecting tank 7.
After the completion of rejecting, rejecting mechanism 6 rotates counterclockwise to initial position, and piston rod starts to stretch out, and passes through 16 band of pin shaft
Dynamic De-scaling box 3 is rotated clockwise to horizontal position around the center line of rotary shaft 15, continues de-scaling operation.
To sum up, traditional 15MPa--25MPa high-pressure water descaling method is changed to the water of low pressure, gas mixing de-scaling by the present invention,
Using the purging of the cooling effect of water, rending effect and compressed air, realize that scale removal effect 90% or more, meets Rolling production
The requirement of line.
The present invention can be achieved freely to overturn, and solve the problems, such as to reject asking for steel billet when descaling device is interfered with rejecting mechanism
Topic.
In addition, the configuration of the present invention is simple, low cost.Water, gas are respectively from cooling water pipeline, the compressed air hose in production line
Branch is drawn in road, is consumed energy low, maintenance cost is low.
As known by the technical knowledge, the present invention can pass through the embodiment party of other essence without departing from its spirit or essential feature
Case is realized.Therefore, embodiment disclosed above, in all respects are merely illustrative, not the only.Institute
Have within the scope of the present invention or is included in the invention in the change being equal in the scope of the present invention.
