The hydraulic cylinder is mounted on an outer cover of the descaling case, the reversing wheel arranged on one side of the top of the outer cover of the descaling case corresponds to an outlet of the outer cover of the descaling case, the baffle plate is disposed at an inlet of the outer cover of the descaling case, the size of the baffle plate is proper so that the inlet of the outer cover of the descaling case can be sealed by the baffle plate, a guide chain arranged on the baffle plate is connected with a piston rod of the hydraulic cylinder via the reversing wheel, and the photoelectric tube arranged at the position of the inlet of the outer cover of the descaling case is aligned to a plate conveying roll way and connected with a control mechanism of the hydraulic cylinder. The iron sheet splashing prevention device retains oxide iron sheets and water inside the descaling case, avoids falling-off and cracking of refractory materials of a furnace door due to water feeding of a heating furnace, and also eliminates the hidden risk of damaging cables on a cable rack.
Description
Technical field
The utility model relates to steel rolling equipment, the anti-iron sheet of the particularly a kind of De-scaling box device that splashes.
Background technology
Slab is after being heated to about 1200 degree, and the surface has produced the iron scale about nearly 1mm.The iron scale of steel slab surface must be removed before rolling, is pressed into defective otherwise product surface will produce iron scale, causes the generation of waster.
We are referred to as de-scaling the removed process of iron scale, and de-scaling equipment is De-scaling box, and it mainly comprises two groups of four high-pressure water pipe of symmetric arrangement up and down, and 26 nozzles are installed on the every high-pressure water pipe, and jet angle is 35 degree.In the de-scaling process, roller-way moves slab forward with the speed of 1.2m/s, and when the slab head arrived the photoelectric tube place, high-pressure water pipe ejected 210kg/cm
2The water under high pressure of pressure, water under high pressure washes away steel slab surface, makes the iron scale that is wrapped in steel slab surface become flexible, come off.After the slab afterbody had gone out De-scaling box, de-scaling water was closed.
In the de-scaling process, after slab had all advanced the De-scaling box outer cover, the iron scale that part is become flexible, come off sputtered the De-scaling box outer cover with de-scaling water along the rightabout that slab moves, and arrived the stove gate of heating furnace, caused the heating furnace water inlet; The cable trough of heating furnace below is piled up a large amount of iron scales, and cable has the potential safety hazard that is scorched by the iron scale of high temperature, so the iron scale in the De-scaling box must be blocked in the De-scaling box.
Summary of the invention
The purpose of this utility model is to design the anti-iron sheet of a kind of De-scaling box device that splashes, and makes iron scale and water be blocked in the De-scaling box the inside, eliminates the fire door refractory material that causes because of the heating furnace water inlet and comes off and ftracture, and has also eliminated the hidden danger of cable bad on the cable trough.
For achieving the above object, the technical solution of the utility model is,
The anti-iron sheet of a kind of De-scaling box device that splashes, it comprises, hydraulic jack is installed on the De-scaling box outer cover; Reverse wheel is arranged at De-scaling box outer cover top one side, the import of corresponding De-scaling box outer cover; Baffle plate is arranged at the import of De-scaling box outer cover, and size is for can seal the import of De-scaling box outer cover; Be provided with on the baffle plate and lead chain, lead chain and be connected with hydraulic cylinder piston rod through reverse wheel; Photoelectric tube is arranged at De-scaling box outer cover import department, aims at the slab rollgang; Photoelectric tube is connected with the hydraulic jack controlling organization.
Further, the both sides of described De-scaling box outer cover import are provided with for baffle plate lifting, spacing gathering sill.
Described reverse wheel is provided with two, establishes two on the baffle plate and leads chain, is connected in a connecting rod through two reverse wheels respectively, and connecting rod is connected with hydraulic cylinder piston rod.
Also connect an activity-oriented support under the described connecting rod.
Advantage of the present utility model is:
But the utility model is by installing the baffle plate of oscilaltion in De-scaling box outer cover import department, make iron scale and water be blocked in the De-scaling box the inside, the fire door refractory material that elimination causes because of the heating furnace water inlet comes off and ftractures, and has also eliminated the hidden danger of cable bad on the cable trough.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment;
Fig. 2 is the schematic diagram of barrier driving among the utility model embodiment;
Fig. 3 is for leading the schematic diagram of chain and connecting rod among the utility model embodiment.
The specific embodiment
Referring to Fig. 1～Fig. 3, the anti-iron sheet of the De-scaling box of the present utility model device that splashes, it comprises, hydraulic jack 1 is installed on the De-scaling box outer cover 12; Two reverse wheels 2 are arranged at De-scaling box outer cover 12 tops one side, corresponding De-scaling box outer cover import 121; Baffle plate 3 is arranged at the import of De-scaling box outer cover, and size is for can seal the import of De-scaling box outer cover; Be provided with two on the baffle plate 3 and lead chain 4,4 ', lead chain 4,4 ' for two and be connected with hydraulic jack 1 piston rod 101 by a connecting rod 5 through two reverse wheels 2, connecting rod also connects an activity-oriented support 6 for 5 times; Photoelectric tube 7 is arranged at De-scaling box outer cover import department, aims at slab rollgang 8; Photoelectric tube is connected with the hydraulic jack controlling organization.
The both sides of described De-scaling box outer cover import are provided with for baffle plate 3 liftings, spacing gathering sill 9, make the baffle plate can only knee-action, can't move forward and backward.
Hydraulic cylinder control piston rod forward-reverse, piston rod promote connecting rod motion backward forward, connecting rod in the forward-reverse process by activity-oriented stent support two ends.Lead chain and under the drive of connecting rod, drag the baffle plate rise and fall through two reverse wheels.
Before slab advanced De-scaling box, the piston rod in the hydraulic cylinder was reclaiming the position, and baffle plate rests on raised position, guarantees that slab can enter De-scaling box.When slab 10 heads arrived photoelectric tube 7 places, descaling header 11 ejected 210kg/cm
2The water under high pressure of pressure, roller-way moves slab forward with the speed of 1.2m/s, and water under high pressure washes away steel slab surface, makes the iron scale that is wrapped in steel slab surface become flexible, come off.After slab entered De-scaling box, when afterbody left the photoelectric tube place, the piston rod of hydraulic cylinder stretched out, and baffle plate descends, and iron scale and water all are blocked in the De-scaling box the inside, had eliminated the fire door refractory material that causes because of heating furnace 13 water inlets and had come off and ftracture.After slab had gone out De-scaling box, descaling header stopped inject high pressure water.Piston rod in the hydraulic cylinder reclaims, and baffle plate is raised, and rests on raised position.
When needing inverted running because of reason slabs such as equipment faults after pausing in De-scaling box, baffle plate can not rise after descending automatically, rise baffle plate after switching to manual mode, otherwise baffle plate may be broken.
When slab does not also enter De-scaling box, have only the interior piston rod of hydraulic cylinder when reclaiming the position, roller-way could just change.When slab has entered De-scaling box or has gone out De-scaling box, have only the interior piston rod of hydraulic cylinder when reclaiming the position, roller-way could reverse.
In sum, use the utility model after, water and iron scale in the De-scaling box have been blocked in the De-scaling box, have eliminated the fire door refractory material that causes because of the heating furnace water inlet and have come off and ftracture, and have also eliminated the hidden danger of cable bad on the cable trough.
