27 in left position, and upper roller of moulding adobe blocks is lifted.Thus having carried out send dummy ingot to prepare.
In dummy bar feeding straightening frame, when the dummy bar head of dummy bar enters between the up-down rollers of the 6th throwing frame, 5
DT obtains electric, 4DT dead electricity, selects reversal valve 17 in left position above and below throwing, the throwing hydraulic cylinder 8 of the 6th throwing frame is depressed, with
When dummy bar is sequentially entered between the four, the second, first throwing frame up-down rollers, the throwing of the four, the second, first throwing frame
Hydraulic cylinder is depressed successively, and dummy bar is admitted to crystallizer, and drawing steel preparation so far in the normal mode is ready.
When starting to draw steel, dummy bar head hauls 9DT when steel billet enters the pressure range for roller of moulding adobe blocks and obtains electric, and 8DT dead electricity is moulded adobe blocks
Selection reversal valve 27 disengages steel billet and dummy bar head, while 7DT dead electricity, low pressure relief valve 31 in right position up and down under roll-in of moulding adobe blocks
Work, hydraulic cylinder of moulding adobe blocks is in low pressure（3MPa）State.2DT dead electricity, 1DT obtains electric, and pressure selects reversal valve 16 in right position, the
First, the hydraulic cylinder of the second, the 4th and the 6th throwing frame is also at low pressure（3MPa）State, until drawing steel to terminate.
2. slighter compress pattern
In the hydraulic control system of the first, second, the 4th and the 6th throwing frame, 4DT dead electricity, 5DT also dead electricity, above and below throwing
Reversal valve 17 is selected in middle position, the locking of dual hydraulic control one-way valve 19, the voltage-controlled check valve 19 of biliquid is conventional hydraulic unit 26 and throwing
Hydraulic cylinder 8 is disconnected, while 3DT obtains electric, model selection reversal valve 20 is opened in left position, hydraulic control one-way valve 21, dual hydraulic control one-way valve 23
Lock, slighter compress hydraulic pressure unit 25 is connected with throwing hydraulic cylinder 8, while 3DT in the hydraulic control system of the three, the 5th throwing frames
Obtain electric, model selection reversal valve 20 is unlocked in left position, hydraulic control one-way valve 21 and dual hydraulic control one-way valve 23, the three, the 5th Blank drawing machines
The slighter compress hydraulic pressure unit 25 of frame is connected with hydraulic cylinder.
Referring to Fig. 5, when sending dummy ingot, pressure selection valve 29 is upper, and high-pressure overflow valve 30 works, 28 pairs of pressure-reducing valve of moulding adobe blocks
System pressure（10MPa）Hydraulic system pressure after decompression is high pressure（6MPa）State, 8DT obtains electric, 9DT dead electricity, mould adobe blocks above and below
Select reversal valve 27 in left position, upper roller of moulding adobe blocks is lifted.Six, the five, the four, the three, the second, the upper pressure roller of the first throwing frame
Lifted successively in the presence of corresponding servo valve, when the dummy bar head of dummy bar is entered between frame up-down rollers, corresponding machine
The electric signal of frame is acted on corresponding servo valve, the throwing hydraulic cylinder 8 of the frame is driven upper pressure roller pressure.So complete to send
The operation of dummy ingot.
When start draw steel when, dummy bar head haul steel billet enter mould adobe blocks roller pressure range when, 9DT obtains electric, 8DT dead electricity, take off
Select reversal valve 27 in right position above and below base, the upper pressure roller pressure for frame of moulding adobe blocks disengages steel billet and dummy bar head, while 7DT obtains electric,
Pressure selection valve 29 works in bottom, low pressure relief valve 31, and hydraulic cylinder of moulding adobe blocks is in low pressure（3MPa）State.Slighter compress pattern
Under, Ju is according to the corresponding roll gap technological parameter of different steel grades, by electric signal to the throwing frame hydraulic pressure of the first throwing frame~the 6th
The servo valve of system is controlled, to reach required roll gap size, realizes expected drafts.So as to reach the small side of improvement
The purpose of base steel billet quality.
