Abstract
The utility model relates to an oxygen lance for smelting, in particular to a super high-power coherent oxygen lance, which is orderly provided with a main oxygen channel, a gas channel, an auxiliaryoxygen channel and a water cooling channel from inside to outside. The super high-power coherent oxygen lance is characterized in that the outlets of the gas channel and the auxiliary oxygen channel are respectively in a groove structure. The utility model has the advantages that the gas channel and the auxiliary oxygen channel respectively adopt the groove structure; the ventilation quantity is large; the production efficiency is enhanced; the smelting cost is reduced; and the utilization rate of gas is effectively enhanced.
Description
Technical field
The utility model relates to the oxygen rifle of smelting usefulness, particularly a kind of ultra high power coherent oxygen lance.
Background technology
Smelt the oxygen rifle of usefulness, need high power, big flow, the ability preheating is fast, enhances productivity, reduce smelting cost, effectively improve the utilization rate of combustion gas, but present oxygen rifle, its blast tube and secondary oxygen passage are by forming passage in the punching of the exit of oxygen rifle, it is little to have passage, can not satisfy production requirement.
Summary of the invention
The passage little deficiency of the utility model in order to overcome the oxygen rifle provides a kind of ultra high power coherent oxygen lance, and to improve power, enlargement discharge is enhanced productivity, and reduces smelting cost, effectively improves the utilization rate of combustion gas.
The utility model is realized by following measure:
Ultra high power coherent oxygen lance of the present utility model from inside to outside is followed successively by main oxygen passage, blast tube, secondary oxygen channel and water cooling passageway, and its special feature is: the exit of described blast tube and secondary oxygen channel is groove structure.
Ultra high power coherent oxygen lance of the present utility model; by the coherent oxygen lance inner core of hollow, be socketed in the outer coherent oxygen lance of coherent oxygen lance inner core cover and be socketed in the coherent oxygen lance outer water-cooling protective sleeve three parts of cover and form; described main oxygen passage is the hollow channel of coherent oxygen lance inner core; described blast tube is the passage that forms between the cover in coherent oxygen lance inner core and the coherent oxygen lance; described secondary oxygen channel is the passage that forms between cover and the water-cooling protective sleeve in the coherent oxygen lance, and cooling-water duct is the passage in the water-cooling protective sleeve.
Ultra high power coherent oxygen lance of the present utility model, in boundling rifle inner core and the boundling rifle cover rear end be connected be by the side have the flange of U type groove and be fixed in the loose joint bolting of overlapping on the sidewall be connected, the internal diameter of cover front end equates that the outside of boundling rifle inner core front end has some radially air channels in the external diameter of boundling rifle inner core front end and the boundling rifle; Cover is to have the flange of U type groove by the side to be connected with loose joint bolting on being fixed on the water-cooling protective sleeve sidewall with being connected of water-cooling protective sleeve rear end in the boundling rifle; the external diameter of cover front end equates with the internal diameter of water-cooling protective sleeve front end in the boundling rifle, and the outside of cover front end has some radially air channels in the boundling rifle.
The beneficial effects of the utility model are, blast tube and secondary oxygen channel adopt groove structure, and it is big to have a throughput, and production efficiency improves, and smelting cost reduces, and effectively improves the utilization rate of combustion gas.
