Description
Technical field
The utility model relates to the pushing off the slag equipment that a kind of converter steelmaking is used, and specifically a kind of converter slag stopper throwing device is applicable to that converter puts the steel later stage and use when stopping slag in stove.
Background technology
In the convertor steelmaking process, before tapping stops, need in stove, throw slag stopper usually, make molten steel separate outflow with slag.Used slag stopper comprises slag-blocking ball, floating plug or scum rod at present, progressively arrive and enter in the tap hole with molten steel flow, the proportion that utilizes slag stopper is lighter than molten steel and overweights the characteristics of slag, make between its molten steel and slag that floats on tap hole, when steel flow near at the end, slag stopper sealing tap hole prevents that in-furnace slag from flowing into ladle, to improve the quality of molten steel.But the weak point that present slag stopper exists is: because slag viscosity is big, slag stopper often can not be located when molten steel will flow to end accurately and effectively and be got lodged in the tap hole place; Because too early shutoff tap hole often, reduced the rate of recovery of molten steel again.The method of throwing in slag stopper at present in stove has two kinds: the one, and artificial input is wasted time and energy, and dangerous; The 2nd, machinery is thrown in, and the equipment complexity is located inaccurate; In addition, no matter be artificial input, still machinery is thrown in, and all exists slag stopper not get lodged on the tap hole accurate, in good time location, influences the tapping rate and goes out steel quality.
Summary of the invention
The purpose of this utility model is to overcome above the deficiencies in the prior art, provides a kind of and can locate the shutoff tap hole in good time, exactly, and is simple in structure again, time saving and energy saving, and is convenient to the converter slag stopper throwing device of safety operation.
For reaching above purpose, the technical scheme that the utility model adopted is: this converter slag stopper throwing device, comprise lifting support, guide cylinder constitutes, it is characterized in that lifting support is connected with guide cylinder by connecting support bar, in guide cylinder, insert flexible positioning pipe, be provided with pull bar in the flexible positioning pipe, the seat end of pull bar is established tightening spring, seat end at flexible positioning pipe is also established handle, establish the mouth hanging of slag stopper link at the front end of flexible positioning pipe, can make flexible positioning pipe on the one hand before guide cylinder, move the back, to determine to enter the distance in the stove, make the mouth hanging of slag stopper link of the front end of flexible positioning pipe be in the top of tap hole, on the other hand can be by the pulling stay cord, make the pull bar retraction in the flexible positioning pipe, make the slag stopper that is suspended on flexible positioning pipe front end fall into tap hole, stay cord passes on the spring stop piece of rear end that tightening spring is fixed on pull bar.The utility model is also implemented by following measure: described guide cylinder is a steel pipe manufacturing, and flexible positioning pipe inserts in the guide cylinder, so that flexible positioning pipe only moves axially supreme, bottom offset along guide cylinder; The skin of described flexible positioning pipe is a refractory masses, can overcome the severe environment in the burner hearth, inside is buried supporting steel pipe underground along the axle center, welding handle on the outer wall of supporting steel pipe, the tube chamber that stay cord passes handle enters in the flexible positioning pipe, and is fixedly connected on the seat end spring stop piece of pull bar; Described lifting support comprises that vertical guide, sliding panel, halliard, pulley and motor constitute, the sliding panel dual-side is stuck in the groove of vertical guide, halliard one end is fixed on the upper edge of sliding panel, the other end is walked around pulley and is connected with winding roller on the motor shaft, pulley and motor all are fixed on the frame plate, and the lower edge of sliding panel is connected with guide cylinder by connecting support bar.When using the utility model, should do corresponding improvement, comprise that cock body, suspension ring, suspension rod constitute slag stopper.When use, the tension stay cord compresses tightening spring earlier, contracts behind the pull bar, the suspension ring mouth hanging that exposes slag stopper, the suspension ring of slag stopper are snapped on the slag stopper mouth hanging, unclamp stay cord, tightening spring automatically resets, pull bar is to front slide, pass the endoporus of slag stopper upper lift ring, slag stopper promptly is suspended on the front end of flexible positioning pipe, promotes flexible positioning pipe forward, flexible positioning pipe is stretched out forward along guide cylinder, slag stopper is sent in the stove, and above tap hole, located, when looking molten steel and will flow to end, spur stay cord again, the pull bar retraction, pull bar withdraws from from the endoporus of suspension ring, and slag stopper promptly falls into tap hole.
The beneficial effects of the utility model are: compare with manually slag stopper being sent in the stove at present, operational safety, accurate positioning, shutoff are appropriate opportunity; Send into the machinery of present use and to compare, simple in structure, cost is low, easy to use, time saving and energy saving, pushing off the slag is effective.
