Abstract
The utility model discloses a seamless oxygen-determined tube which comprises a tube body (1) and a tube head (2), wherein the tube head (2) is horn-shaped, a small section of cylindrical tube is arranged at a horn mouth of a large end, fourteen annular triangular grooves (3) which are arranged at 2mm intervals and seven annular triangular points (3) which are arranged at 2mm intervals are respectively arranged on the outer wall of the tube body (1), respectively away from the other end of the tube body (1) by 3mm and 61mm, the cross section of each annular triangular point (3) is shaped like a V with apex angle of 60 degrees, and the tube body (1) and the tube head (2) are both machined by adopting seamless tubes, thereby solving the problem that tube walls have gaps. The seamless oxygen-determined tube is simple in structure, and free from any accessories, so that the problem that tube walls have gaps can be solved, the aperture sizes of the tube body (1) and the tube head (2) can not be changed due to extrusion and are stable so as to be easily and accurately assemble the tube body (1) and the tube head (2), gas leakage can be avoided, and gas can be stably provided.
Description
Technical field
The utility model relates to steel-making accessory technical field, is specifically related to a kind of seamless oxygen pipe of deciding.
Background technology
Modern Electric furnace steel making nearly all adopts oxygen blast technique, is intended to saves energy and shortens the heat.Oxygen blast technique is exactly by the oxygen blowing apparatus in the molten iron that is inserted in melting in electric furnace, the technical measures of delivering oxygen in the stove, and wherein deciding the oxygen pipe is the important accessory of oxygen blowing apparatus.have now and decide the oxygen pipe, include body and tube head, described tube head is horn shape, large end hydraucone is provided with a bit of cylindrical tube, on described tube wall, be provided with respectively the annular triangle groove of one section 14 interval 2mm and the annular choppy sea mouth of one section 7 interval 2mm apart from body the other end 3mm and 61mm place, the cross section of described annular choppy sea mouth (3) is that drift angle is 60 ° of V fonts, but there is a gap in the tube wall of described oxygen lance, the caliber size of body and tube head can be squeezed and change, be difficult to assemble, easily cause and come off, also cause simultaneously gas leakage, can't stablize provides gas, reduce and decide oxygen pipe use properties.
The utility model content
In order to overcome the deficiency of background technology, the utility model provides a kind of seamless oxygen pipe of deciding, and has mainly solved the problem that there is a gap in the tube wall of deciding the oxygen pipe in the oxygen blowing apparatus, avoids oxygen leakage and size unstable.
the technical scheme that the utility model adopts is: a kind of seamless oxygen pipe of deciding, include body and tube head, described tube head is the round speaker shape, large end hydraucone is provided with a bit of cylindrical tube, on described tube wall, be provided with respectively the annular triangle groove of one section 14 interval 2mm and the annular choppy sea mouth of one section 7 interval 2mm apart from body the other end 3mm and 61mm place, the cross section of described annular choppy sea mouth (3) is that drift angle is 60 ° of V fonts, described body and tube head all adopt seamless tubular goods to process, can solve tube wall and deposit apertured problem, the caliber size of body and tube head can be squeezed just to change, be convenient to processing and manufacturing, be easy to assemble, reduce production costs, also avoid simultaneously oxygen to reveal, improve the seamless oxygen pipe use properties of deciding.
The beneficial effects of the utility model are, the utility model is simple in structure, without any annex, deposit apertured problem with regard to solving tube wall, the caliber size of body and tube head can be squeezed just change, be convenient to processing and manufacturing, be easy to assemble, reduce production costs, avoid oxygen to reveal, improve the seamless oxygen pipe use properties of deciding.
