Description
Technical Field
The utility model relates to the technical field of auxiliary facilities of blast furnace workshops, in particular to a blast furnace oxygen lance with good cooling effect.
Background
In the blast furnace ironmaking production of a steel plant, after long-term overhauling and wind stopping in the blast furnace, the temperature of slag iron in a hearth is greatly reduced, and the hearth is heated as soon as possible in the early stage of air supply and production recovery. In order to melt and discharge the slag iron in the hearth as early as possible, a mode of blowing a tap hole or directly extending into the tap hole by an oxygen pipe to heat the hearth is generally used at present, and a blast furnace oxygen lance is needed. However, the existing blast furnace oxygen lance is often unreasonable in structural design, adopts ditch material cooling, has poor cooling effect and is easy to scald operators. Meanwhile, no peeping hole is arranged, so that the observation of flame conditions in a hearth is not facilitated, and inconvenience is brought to the operation of the iron blowing port.
The utility model discloses a blast furnace oxygen gun (grant bulletin No. CN 216585046U) with good cooling effect, which increases oxygen flow by symmetrically arranging two oxygen pipes which are obliquely inserted forward and communicated at two sides of a communicated pipe fitting, and simultaneously outputting oxygen through the two pipelines; the outer sleeve is coaxially sleeved at the front end of the main oxygen lance, an interlayer for circulating compressed air is arranged between the main oxygen lance and the outer sleeve, and the main oxygen lance is subjected to air cooling, so that the cooling effect is good; through setting up peeping tube and camera lens spare at the intercommunication pipe fitting rear end, the staff of being convenient for observe the inside flame condition of hearth through the camera lens spare. Set up helical blade between through main oxygen lance and the outer tube, cut apart the intermediate layer clearance into spiral wind channel, can increase the helical pitch in cooling wind channel, improve the utilization efficiency of cooling wind, the cooling is more even moreover. The root of the peeping tube is connected to the communicating pipe through threads, and the peeping tube is convenient to detach, maintain and clean relative to a welding connection mode, is locked by adopting a lock nut, so that the connection firmness of the peeping tube is guaranteed, and the peeping tube and the main oxygen blowing tube are good in coaxiality. Through the arrangement of the heat insulation sheath, the oxygen lance operator can conveniently hold the oxygen lance during the gun holding, the holding hand feeling after thickening is easy to control, and the risk of burning and scalding is reduced. This practicality is when carrying out the oxygen blowing, can't observe the inside atmospheric pressure of oxygen blowing pipe, probably causes because of the pressure is too big to lead to the body to appear the material impaired, and is carrying out the oxygen blowing, and the oxygen can't regulate and control the temperature of flame of blowing in of one's taste.
