Specific embodiment
With reference to the accompanying drawings and detailed description the present invention is described in further details.
As shown in Figure 1 and Figure 2, the embodiment of the present invention includes driving means 1, rotating shaft assembly 2, dephosphorization case 3, water pipe 8, water
Nozzle 81, trachea 9, gas jets 91, riser 11, bearing pin 16, support 17, the base 18 of steel rolling production-line.In order to clearer aobvious
Show that the present embodiment is non-interference with rejecting mechanism 6, Fig. 1, Fig. 2 also show the continuous casting billet 5 producing 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, around the swingable setting of continuous casting billet 5, extends on the left side of continuous casting billet 5, upside, right side.Preferably
Ground, as shown in Figure 3, Figure 4, water pipe 8 is in inverted u shape, and downside opens, tips upside down on continuous casting billet production line and continuous casting billet 8.Multiple
(operating) water nozzle 81 is connected on water pipe 8, and is respectively directed to the left side of continuous casting billet 5, upside, right side, for spraying water to continuous casting billet 5.With
Water pipe 8 is identical, and trachea 9, around the swingable setting of continuous casting billet 5, extends on the left side of continuous casting billet 5, upside, right side, is also in inverted
U shape, arranged side by side with water pipe 8.Multiple gas jets 91 are connected on trachea 9, and are respectively directed to the left side of continuous casting billet 5, upside, right side,
For to continuous casting billet 5 jet.It is highly preferred that (operating) water nozzle 81, gas jets 91 are slightly tilted (as schemed to the direction of steel billet incoming side
4).Driving means 1 are connected with water pipe 8, trachea 9, to drive water pipe 8, trachea 9 to complete to swing.
In order to protect water pipe 8, trachea 8 and nozzle thereon, the present embodiment also includes dephosphorization case 3, and it is in inverted u shape knot
Structure, water pipe 8, trachea 9, (operating) water nozzle 81, gas jets 91 are all in dephosphorization case 3.Specifically, in water pipe 8, trachea 9, (operating) water nozzle
81st, outside setting steel plate of gas jets 91 etc., forms a body structure, to avoid water pipe 8, trachea 9, (operating) water nozzle 81, gas jets
91 grades are damaged.
It is highly preferred that in dephosphorization case 3, as shown in Figure 3, Figure 4, being connected by riser 11 between water pipe 8, trachea 9, riser
11 are connected by bolt (not shown) with dephosphorization case 3.
Meanwhile, also allow for the connection with driving means 1.Correspondingly, the driving means 1 of the present embodiment are a cylinder,
It can certainly be oil cylinder.As shown in Figure 1 and Figure 2, the cylinder body of driving means 1 is articulated with support 17, is beneficial to and swings up and down；
Its piston rod is hinged by bearing pin 16 with the one side of dephosphorization case 3, dephosphorization case 3 side hinged with the piston rod of driving means 1
Bottom is provided with rotating shaft assembly 2, and rotating shaft assembly 2 is fixed on base 18, and is located at the side of continuous casting billet 5, is beneficial to dephosphorization
Case 3 drives water pipe, trachea 9 to swing around continuous casting billet 5.Because water pipe 8, trachea 9, (operating) water nozzle 81, gas jets 91 are all located at dephosphorization
In case 3, therefore, when driving means 1 drive dephosphorization case 3 to swing, water pipe 8, trachea 9, (operating) water nozzle 81, gas jets 91 will be put therewith
Dynamic.
As shown in figure 5, rotating shaft assembly 2 includes: bearing block 12, bearing 13, reinforcing plate 14, rotary shaft 15.Two bearings
Seat 12 is fixed on the base 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, dephosphorization case 3 side hinged with the piston rod of driving means 1 is fixedly connected.Further, rotate
Two reinforcing plates 14 are fixed with axle 15, dephosphorization case 3 is fixed between two reinforcing plates 14, and weld with reinforcing 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),
Trachea 9 is relatively distant from steel billet incoming side.
Between the present embodiment normal production period, such as Fig. 1, the piston rod of driving means 1 is in the state of stretching out, and dephosphorization case 3 is in
Horizontality.Spray at an angle in water, the edema caused by disorder of QI (operating) water nozzle 81 that annular is installed not from water pipe 8, trachea 9, gas jets 91
Go out, the iron scale on continuous casting billet 5 is removed, realizes phosphor-removing effect.Preferably, the water source being connected with water pipe 8 is derived from production line
On roll cooling water, in 0.4mpa-0.5mpa, the source of the gas being connected with trachea 9 is derived from the compressed air of production line, pressure to pressure
For 0.4mpa about, such as 0.35mpa-0.45mpa, by the control of control valve, achievable automatic start-stop.
As shown in Fig. 2 when rejecting problem continuous casting billet 5, water source, source of the gas are first shut off, the present embodiment stops dephosphorization work.
Under electric control system controls, its piston rod starts to shrink at driving means 1, and the contractile motion of piston rod drives dephosphorization by bearing pin 16
Case 3 and the water pipe 8 arranging thereon, trachea 9, (operating) water nozzle 81, gas jets 91, around the centrage rotate counterclockwise of rotary shaft 15, are left
The operating radius of rejecting mechanism 6, rejecting mechanism 6 turns 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 is carried by bearing pin 16
Dynamic dephosphorization case 3 is rotated clockwise to horizontal level around the centrage of rotary shaft 15, continues dephosphorization operation.
To sum up, traditional 15mpa--25mpa water under high pressure phosphorus removing method is changed to the water of low pressure, gas mixing dephosphorization by the present invention,
Using the purging of the cooling effect of water, rending effect and compressed air, realize phosphor-removing effect more than 90%, meet Rolling production
The use requirement of line.
The present invention can achieve and freely overturns, and solves and rejects asking of problem steel billet when dephosphorization apparatus are interfered with rejecting mechanism
Topic.
Additionally, present configuration is simple, low cost.Cooling water pipeline not from production line of water, edema caused by disorder of QI, compressed air hose
Branch road is drawn in road, and power consumption is low, and maintenance cost is low.
As known by the technical knowledge, the present invention can be by the embodiment party of other essence without departing from its spirit or essential feature
Case is realizing.Therefore, embodiment disclosed above, for each side, is all merely illustrative, and is not only.Institute
Have within the scope of the present invention or be all included in the invention in the change being equal in the scope of the present invention.
