Abstract
The utility model relates to a safe steelmaking equipment, it includes the furnace body, be equipped with the induction coil in the furnace body, the exit end of induction coil passes through the pipeline and is connected with the cooling interchanger, cooling interchanger and nitrogen gas high pressure compressor intercommunication, nitrogen gas high pressure compressor connects storage nitrogen jar, just store up the nitrogen jar with the inlet connection of induction coil. This equipment replaces traditional hydrologic cycle to come cooling steelmaking furnace body with the liquid nitrogen, can eliminate the potential safety hazard.
Description
Technical field
The utility model relates to field of steel-making, particularly relates to a kind of safe steelmaking equipment.
Background technology
At present, steel-making body of heater is all use water cycle cooling mostly, and the maximum shortcoming of water cycle is exactly that molten steel runs into water and will blast, and there is very large potential safety hazard when water pipe breakage in body of heater.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of safe steelmaking equipment, replaces traditional water cycle to cool steel-making body of heater, to eliminate safe hidden trouble with liquid nitrogen.
For reaching above-mentioned purpose, the steelmaking equipment of the utility model safety, it comprises body of heater, induction coil is provided with in described body of heater, the exit end of described induction coil is connected with cooling exchanger by pipeline, described cooling exchanger is communicated with nitrogen high pressure compressor, and described nitrogen high pressure compressor connects storage nitrogen tank, and described storage nitrogen tank is connected with the entrance end of described induction coil.
Preferably, above-mentioned steelmaking equipment also comprises controller, and it is electrically connected with described induction coil, described nitrogen high pressure compressor, described storage nitrogen tank and described cooling exchanger.
Steelmaking equipment of the present utility model, is provided with spiral coil cooling tube in wherein said cooling exchanger.
The utility model difference from prior art is that the utility model achieves following technique effect: when combustion chamber cooling tube breaks, and prevents legacy equipment water from running into molten steel and causes danger, eliminate safe hidden trouble.
Below in conjunction with accompanying drawing, safe steelmaking equipment of the present utility model is described further.

Embodiment
Below in conjunction with drawings and Examples, to above-mentioned being described in more detail with other technical characteristic and advantage of the utility model.
As shown in Figure 1, in an embodiment, the steelmaking equipment of the utility model safety, it comprises body of heater 1, cooling exchanger 4, nitrogen high pressure compressor 3 and storage nitrogen tank 2.
Body of heater 1 comprises converter nose 11, sealing compound 12, induction coil 13, work furnace lining 14 and furnace shell, the exit end of induction coil 13 is connected with cooling exchanger 4 by pipeline 7, cooling exchanger 4 is communicated with nitrogen high pressure compressor 3, nitrogen high pressure compressor 3 connects storage nitrogen tank 4, and storage nitrogen tank 4 is connected with the entrance end of induction coil 13.Logical in the induction coil 13 of body of heater
Compression low temperature liquid nitrogen.
Nitrogen from stove 1 out after temperature will increase, first through water cooling interchanger 4, water cooling interchanger 4 is exported 45 formed by cooler casing 41, cooling tube 42, hot water outlet 44, cold water, nitrogen flows to below in spiral coil cooling tube 42 from top, water flows into from below and flows out from the top of interchanger 4, walks the heat of nitrogen by water-band.
From cooling exchanger 4 nitrogen out cool to room temperature again through high pressure nitrogen compressor 3 by nitrogen compression cooling, compressor is made up of body 31, first valve 32, duaspiracle 33, cylinder 34, bent axle 35, motor 36 and piston 37, when motor 36 is with dynamic crankshaft 35 to move reciprocatingly, the first valve 32 and duaspiracle 33 do the effect that compressed nitrogen is played in geneva motion.
Through storage nitrogen tank 2, ensure supply stove constant voltage nitrogen.
In another embodiment, controller is set on equipment of the present utility model, its with induction coil 13, nitrogen high pressure compressor 3, store up nitrogen tank 2 and cooling exchanger 4 is electrically connected.Controller controls nitrogen pressure by induction coil temperature feedback control compressor 3, and control storage nitrogen tank 2 output flow, controlled cooling model interchanger 4 power, reaches the object controlling induction coil temperature.
Above-described embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
