Embodiment
Be described in detail below in conjunction with the distribution device of drawings and Examples to a kind of molten steel covering agent of the present invention.
The distribution device of a kind of molten steel covering agent of the present invention, above ladle travel line, need to add molten steel covering agent area starting point increases this distribution device, and as shown in Figure 1, it comprises: hopper 1, hopper on-off mechanism and discharging flow-guiding mouth 9; Described hopper 1 is for carrying molten steel covering agent, and its lower end is provided with discharge port 8; The opening and closing of the position analysis discharge port 8 that described hopper on-off mechanism runs according to ladle, the opening and closing direction of this discharge port 8 is vertical with the traffic direction of ladle; The molten steel covering agent that discharge port 8 flows out is guided to the molten steel surface carried in ladle by described discharging flow-guiding mouth 9.
As shown in Figure 1, based on the distribution device of said structure, in the present embodiment, described hopper on-off mechanism can comprise: switch flashboard chute 3, two jack deflecting rollers 4, two switch flashboards 5, driving jack 7 and hydro-cylinder 10.
Described driving jack 7 to be sheathed between two jack deflecting rollers 4 and to form closed loop, and a switch flashboard 5 fixed by the top chain 11 of described closed loop one end, and another switch flashboard 5 fixed by the below chain 12 of this closed loop the other end.As in Fig. 1, distribution device side cuts the part shown in region 2 open, described hydro-cylinder 10 is connected with a switch flashboard 5, described hydro-cylinder 10 is reciprocating along level by its flexible this switch flashboard 5 that drives, and by driving jack 7 to drive another switch flashboard 5 to do contrary to-and-fro movement along level, two switch flashboards 5 are made to close discharge port 8 when going in the same direction, two switch flashboards 5 open discharge port 8 when opposing and row, described hydro-cylinder 10 is switched on power after being connected with the contact that the ladle run is arranged by the contact switch (not shown) arranged, the position that hydro-cylinder 10 is run according to ladle is opened automatically, one side of two described switch flashboards 5 is all inserted in switch flashboard chute 3.The support 6 floatless switch flashboard 5 of described below chain 12 by being provided with.
Based on the distribution device of said structure, described switch flashboard chute 3 plays the effect of two switch flashboard 5 positions, location; Described jack deflecting roller 4 plays the effect changing chain gear direction; Two switch flashboards 5 are by coordinating the effect jointly played and control discharge port 8 opening and closing; Can be played by the opening degree controlling discharge port 8 and control its blanking size, namely play the effect controlling blanking velocity; Described discharging flow-guiding mouth 9 plays water conservancy diversion molten steel covering agent and controls the effect of the loose area of insulating covering agent paving; Hydro-cylinder 10, by means of only one-sided driving switch flashboard 5, can drive two switch flashboards 5 in opposite directions or opposing and go simultaneously, serve the effect driving flashboard switch.Hydro-cylinder is connected with circuit by hydro-pump, and hydro-cylinder is one action process after completing and being once contracted to full extension.
The detailed process utilizing above-mentioned distribution device to carry out the operation of molten steel covering agent cloth is:
First, above ladle travel line, need to add molten steel covering agent area starting point increases this distribution device, and wherein the opening and closing direction of switch flashboard 5 is vertical with ladle traffic direction.
Then, ladle is placed on travel line, after the contact on the ladle or steel ladle transport vehicle of contact switch and unidirectional operation is connected, hopper on-off mechanism starts with hydro-cylinder 10, a switch flashboard 5 on right side is driven to move horizontally (as shown in Figure 1) when now hydro-cylinder 10 shrinks to the right, drive chain to rotate along clockwise direction simultaneously, and then drive another switch flashboard 5 in left side to move horizontally with below chain 12 left, make because discharge port 8 opened by two opposing and capable switch flashboards 5; And when hydro-cylinder 10 stretches, chain drive-belt rotates in the counterclockwise direction, and then two switch flashboards 5 owing to going in the same direction are made to close discharge port 8.
Two described switch flashboards 5, in the process completing an opening and closing campaign, are made molten steel covering agent flow out in hopper 1, and are sprawled at molten steel upper surface uniformly by the guide functions of discharging flow-guiding mouth 9.
Upper surface due to ladle is circular, and the motion of vertical switch flashboard 5 switch direction, in order to further ensuring coverage is even at the insulating covering agent thickness of molten steel surface, maximum open length between two described switch flashboards 5 can be designed to identical with the bore length of ladle, and the duration that hydraulic control cylinder 10 completes a stretching motion is equal with the duration that ladle runs its bore length, when making ladle mouth edge move to hopper 1 central point, two switch flashboards 5 start to open gradually, molten steel covering agent flows out from discharge port 8 gradually, molten steel surface in vertical instillation ladle, now the area coverage of discharge port 8 increases gradually along with shifting near of ladle mouth.When the mid-way of ladle mouth moves to immediately below discharge port 8, two switch flashboards 5 reach maximum opening, namely hydro-cylinder 10 reaches maximum collapse amount, now the area coverage of discharge port 8 also just reaches maximum, and switch flashboard 5 cuts out gradually along with the stretching, extension of hydro-cylinder 10 subsequently, the overlay area of discharge port 8 reduces gradually, until when the end of ladle mouth moves to immediately below discharge port 8, discharge port 8 is closed by two switch flashboards 5 completely.
Finally, the shape after molten steel covering agent is sprawled and ladle mouth-shaped completely the same, all become the circle of equal diameters, reach good and sprawl coverage effect.
In addition, the sprawling thickness and discharge port size can be regulated to control according to insulating covering agent mobility of molten steel covering agent, namely according to Cover treatment agent mobility, the width of manual regulation discharge port 8, controls to reach the object that thickness sprawled by blanking insulating covering agent.When molten steel covering agent kind is without larger change, mobility fluctuation is little, without the need to frequent adjustment.Utilize above-mentioned distribution device to carry out molten steel covering agent to add and achieve automatization, it is timely to add opportunity, avoids artificial hand and adds into brought random error, and reduce labor intensity of operating staff.
It should be noted last that, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted.Although with reference to embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, modify to technical scheme of the present invention or equivalent replacement, do not depart from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
