Description
Technical field
The utility model belongs to smelter production auxiliary equipment, and it is mainly used in VD stove ladle to monitor.
Background technology
Take production " railroad car axle wheel steel, steel alloy for high-pressure tank, high-strength die steel, high alloy high-quality steel and military project steel " as main special steel steel mill, and above steel grade requires strict especially aspect the degree of purity of mechanical performance, chemical analysis and steel.Therefore smelting process is very meticulous, and the molten steel in ladle is through refining and VD(vacuum) after stove degassed (hydrogen, nitrogen, oxygen), Molten Steel Cleanliness is high, in the past few years VD(vacuum) stove crosses steel and reaches 100%, Molten Steel Cleanliness ensures greatly.
But in process of production, usually there is VD stove ladle excessive slag (average 1.2 tons of stove) in a large number, as long in the ladle bottom high-temperature baking time, deform, slide plate gate mechanism damages, and burns ladle (over 2 years, whole stove is 12 times), burns out slag pan, affects production cost.The only statistics loss of 3 years in the past: 26 of slag pans (1.8 ten thousand yuan /); Slide mechanism 15 covers (17000 yuan/cover); 9 of ladles (19.7 ten thousand yuan /); Badly bleeding accident causes approximately more than 700 tons of production capacity loss accumulative totals; The slag of ladle periphery is unrestrained producing along the line everywhere, contaminated environment, and worker's labour intensity is large, and therefore " solving the excessive slag of VD stove ladle " has been the problem that must solve.
Summary of the invention
The utility model is comprised of one-level water collar, two-stage water-cooling cover and video camera, video camera is arranged on one end of stock, one end of stock is threaded connection fixed mount and binding has video camera, the other end welding flange of stock, ring flange is by short tube connecting tee, and a port of threeway connects nitrogen tube, and wire is connected with video camera with ring flange through threeway, one-level water collar is arranged in two-stage water-cooling cover, and one-level water collar is arranged on the periphery of video camera and stock end; Fixed mount is bolted backplate, and backplate is provided with adjustment hole.
Described fixed mount is U-shaped aluminum component, and fixed mount is bolted backplate, and backplate is bakelite plate, and bakelite plate is provided with for adjusting the camera position adjusting hole of (comprising angle, distance etc.); Adjusting hole is slot.
The utility model is fixedly mounted on above VD bell, is wired to control room, in control room, can observe clearly ladle liquid level, make the control nitrogen pressure slag that direct labor can be good, thereby thoroughly eliminate ladle badly bleeding accident.Reduce workman's labour intensity, reduce device damage, extension device service life, reduce production costs.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
Fig. 2 is the left view of Fig. 1.
In figure, 1, inflated with nitrogen pipe, 2, ring flange, 3, wire, 4, fixed mount, 5, two-stage water-cooling cover outlet pipe, 6, two-stage water-cooling cover, 7, one-level water collar, 8, backplate, 9, high temperature resistant filter glass, 10, camera, 11, two-stage water-cooling cover water inlet pipe, 12, stock, 13, threeway, 14, adjusting hole, 15, one-level water collar outlet pipe, 16, one-level water collar water inlet pipe.
The specific embodiment
Shown in Fig. 1, Fig. 2, camera 10 of the present utility model adopts 8 times of focal length minisize pick-up heads, in order to protect camera, at camera front end, a resistant to elevated temperatures filter glass 9 is installed.
Camera 10 fixedly mounts (with adhesive tape, bundling) in one end of stock 12 and connects by wire 3, and wire 3 bundles with stock 12 use adhesive tapes.The other end welding flange 2 of stock 12, ring flange 2 is by short tube connecting tee 13, and a port of threeway 13 passes into nitrogen, and wire 3 is connected with camera 10 with ring flange through threeway;
One-level water collar 7 is enclosed within the periphery of stock 12 ends and camera 10, and two-stage water-cooling cover 6 is enclosed within one-level water collar 7 peripheries; The water inlet pipe of one-level water collar connects filter;
By screw thread and fixed mount 4, fixing (stock 12 is aluminum pipe to stock 12, the end of stock 12 is provided with external screw thread, at the bottom of the U-shaped of fixed mount 4, be provided with internal thread hole), fixed mount 4 is U-shaped aluminum component, fixed mount 4 inner sides have been bolted bakelite backplate 8, the end of bakelite backplate 8 is provided with adjusting hole 14, and adjusting hole 14 is for the convenient position of adjusting camera 10.
In one-level water collar, pass into recirculated cooling water, water pressure > 0.3MPa.
Two-stage water-cooling cover selects general steel plate to process, and two-stage water-cooling cover utilizes VD bell water circulation cooling, water pressure > 0.3MPa.
In STEELMAKING PRODUCTION, the nitrogen that pressure is about 0.3Mpa is entered by threeway porch, by entering in fixed mount in one-level water collar, make one-level water collar inner chamber form malleation, nitrogen sprays and injects VD stove in the form of a ring from the periphery gap of camera, to stop high-temperature gas or slag splash in VD stove to damage video camera.In one-level water collar, introduce recirculated cooling water, the temperature that reduces video camera surrounding enviroment is suitable, maintains video camera and normally works.And one-level water collar inserts in two-stage water-cooling sleeve pipe; like this; expanded cooling area, cooling-down effect is obvious, after testing; maximum temperature is no more than 40 ℃; two-stage water-cooling cover is not only lowered the temperature for one-level water collar, and has prevented one-level water collar contingent explosion danger when leaking or stopping up, and it is safe safe to have guaranteed; the application of two-stage water jacket, has in fact formed again duplicate protection to camera.
Dynamic menu that master-control room is observed ladle liquid level from monitor is clear, control that molten steel mixing effect is good, system water temperature normal, camera lens self-protecting is good, stopped ladle badly bleeding, reduced slag pan consumption, and the overflow difficult problem of slag of ladle has also obtained properly settling.
