Abstract
The utility model relates to a fast joint for oxygen blowpipe which is used for steel processing such as iron-smelting and steel-smelting, comprising a joint main body sleeve pipe. The fast joint for oxygen blowpipe is characterized in that: the middle of the joint main body sleeve pipe is provided with an extrusion forming circular arc fix position fall in table dog. The inner wall of the joint main body sleeve pipe arranged on the overlapping section of the joint main body sleeve pipe and the oxygen blowpipe is provided with a layer of fluid sealant. The overlapping section is provided with an extruding groove. One to three extruding grooves 4 are provided be the utility model. The fast joint for oxygen blowpipe has the advantages of light weight, good sealing performance, firm joint and safety so that the redundant part of the oxygen blowpipe can not be discarded and waste phenomenon is avoided.
Description
Technical field
The utility model relates to a kind of ironmaking, the oxygen lance ready-packaged joint is used in the processing of steel-making steel, belongs to the component technical field of smelting with gas treatment equipment.
Background technique
Oxygen lance belongs to ironmaking, steel-making steel processing consumptive material commonly used, because temperature is higher in the stove, the oxygen lance front end melts very soon, and rear end institute clout head can't use.Manual welding is all adopted in the connection of the oxygen lance clout head of using before ironmaking, the steel making furnace for a long time, and labor strength is big, and the remainder that can't connect has just abandoned, and causes very big waste.For addressing the above problem, people have prepared with technologies such as the oxygen lance joint of scyewed joint and butt welding, but this oxygen lance joint, sealing effect is not ideal enough, and therefore the processing technology complexity is used to be restricted.
Summary of the invention
The purpose of this utility model provides a kind of good seal performance, connects firmly, and is safe and reliable, can squeeze the oxygen lance ready-packaged joint of dress with various oxygen lances fast.
The purpose of this utility model is this realization, comprise the adapter body sleeve pipe, the middle part that it is characterized in that described adapter body sleeve pipe is the circular arc location inner convex platform retaining of extrusion modling, on the inwall of the adapter body sleeve pipe of adapter body sleeve pipe and oxygen lance overlap joint section, one deck sealer is arranged, on this overlap joint section, the extruding groove is arranged.
According to the utility model, described extruding groove is the 1-3 road.
The utility model has the advantages that: this oxygen lance joint is in light weight, and good seal performance connects firmly, safe and reliable, so just the oxygen lance remainder is lost, no wasting phenomena, can save consumptive material 25% in 1 year, and also save a large amount of welding consumabless simultaneously, alleviate working strength of workers.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to accompanying drawing 1, according to plug-in type oxygen lance ready-packaged joint described in the utility model, comprise adapter body sleeve pipe 1, the middle part that it is characterized in that described adapter body sleeve pipe 1 is the circular arc location inner convex platform retaining 2 of extrusion modling, on the inwall of adapter body sleeve pipe 1 and the adapter body sleeve pipe of oxygen lance 5 overlap joint sections, one deck sealer 3 is arranged, on this overlap joint section extruding groove 4 is arranged, described extruding groove 4 is the 1-3 road.
Installation method of the present utility model is: be coated with one deck sealer earlier on internal surface of sleeve pipe, then oxygen lance injected in the sleeve pipe, adopt the mechanical presses mode to squeeze out groove again, promptly finish connection.
The utility model good sealing effect reaches connection desired intensity of oxygen lance and pulling force.Can connect the special steel-making operating condition that adapts to harshness easily with various oxygen lances.
