Description

Blast furnace gun control link
Technical field
The utility model relates to blast furnace gun technical field, particularly relates to a kind of blast furnace gun control link.
Background technology
Blast furnace gun, belong to the extremely important casthouse equipment in ironmaking field, the effect of clay gun can accurately block rapidly the iron notch after putting iron, makes blast furnace enter the operation of next circulation fast, the wherein comparatively ideal casthouse equipment of the current large, medium and small ironmaking producer of Hydraulic clay gun.The YP6000E type Hydraulic clay gun snap-in force 621KN of Tang Gang 3200m3 blast furnace, turning period is 9-13S, the heavy 9268KG of clay extruded mechanism.Under standard state, blast furnace mud gun mouth faces iron notch and makes stemming can block molten iron quickly and accurately, all can affect program of blocking up normally time to the left relative to iron notch reference point or to the right, now need adjustment clay gun to control pull bar and make big gun mouth just in time facing to iron mouth.Control pull bar primarily of compositions such as the jaw at two ends, threaded pull bar, spring cases, for adjusting the horizontal direction of clay gun barrel in clay gun operational process, and having certain shock absorption to reduce surging force, ensureing that big gun mouth faces iron mouth.If mud gun nozzle can not face iron mouth, very easily there is big gun mouth place and emit mud and iron notch cannot be blocked in time, cause big gun mouth, clay extruded mechanism scaling loss can not normally use, generally all can cause blast furnace checking, damping down.Clay gun process speed of blocking up is fast, clay extruded mechanism heavily causes surging force very large, and original clay gun adjustment pull bar is the original-pack production of producer, use this pull bar during 2007 to 2009 always, expose a lot of problem, control pull bar and the middle repeated stress failure of pull bar 2 times occurred, spring case root weld bond snaps 4 times, jaw side, two ends deviates from 1 time, other 2 inferior problems that rupture, by finding existing control link structural analysis, there is following defect in its configuration aspects: 1, first jaw and the first swivel nut be just simple welding originally, original just standby tight with simple nut between first swivel nut and the first pull bar, pull bar frequently draws, pushing through Cheng Jiyi causes the first jaw to loosen, standby female locking effect was lost efficacy very soon, 2, just simply insert welding between existing first pull bar and the second pull bar, weld bond very easily ftractures and deviates from phenomenon, 3, existing adapter sleeve and the second pull bar simply insert welding, and weld easily produces stress concentration, easily ftractures, 4, existing joint sleeve and adapter sleeve are threaded, and do not have anticreep effect, 5, existing spring washer group and the 3rd tie rod end only arrange a set of set nut, and locking effect is poor.
Control these problems of pull bar to directly affects clay gun and to block up efficiency, and then cause the repeatedly industrial accident such as checking, damping down, have a strong impact on conditions of blast furnace, and original control pull bar spare part costly, directly causes production efficiency to decline, production cost raising.
