Abstract
The present invention relates to an auxiliary gun composite proble for a stainless steel smelting furnace, which comprises a ceramic head (1) with a temperature sensor, a middle paper pipe (2), an outer paper pipe (3), a gun measuring head, a connecting-inserting device (4), a sampling component, a sampling liquid inlet (7) and a liquid inlet sealing cap (8), wherein the connecting-inserting device (4) and the sampling component are movably connected with the gun measuring head and the liquid inlet sealing cap (8) is arranged on the sampling liquid inlet (7). The invention is characterized in that a reinforced pipe (9) is arranged in the outer paper pipe (3) and after the middle paper pipe (2) and the outer diameter of the reinforced pipe (9) is in interference fit with the inner diameter of the outer paper pipe (3). The reinforced pipe (9) is arranged in the outer paper pipe (3) and after the middle paper pipe (2) so that the bending strength of a gun body is greatly enhanced, and on the other hand, due to the enhancement of the bending strength of the gun body, the pipe walls of the inner and outer paper pipes can be thinned so that the integral diameter is reduced. When oxygen is blown, side force born by the gun body is further decreased and is not easy to break, and therefore, the invention solves the problem of the gun body which is easy to break in operation in the stainless steel smelting furnace.
Description
Technical field
The present invention relates to a kind of sublance composite probe for stainless steel smelting furnace.
Background technology
Employed sublance composite probe for stainless steel smelting furnace essential structure generally includes probe temperature-measuring part and auxiliary lance probe pipe shaft part in the at present domestic and international smelting iron and steel enterprise; the probe thermometric is decided the oxygen parts and is comprised ceramic head; temperature sensor and tin hat; temperature sensor fixedly is plugged on the ceramic head; the auxiliary lance probe pipe shaft partly comprises middle paper tube; outer paper tube and the docking apparatus that flexibly connects with survey rifle head; in middle paper tube, be provided with by sampling box; the sampling assemble that sampling hut and the sampling liquid inlet port that is communicated with the sampling hut are formed; the liquid inlet port import is provided with the liquid inlet port capping; integral body placed outer paper tube leading portion with docking apparatus after sampling assemble was arranged on middle paper tube, and ceramic head is fixed on the outer paper tube front end.Owing to employing in stainless steel converter and stainless steel precision furnace (AOD stove) is one-sided oxygen blast mode, sublance composite probe is one-sided stressed in stove, phenomenon of rupture often takes place, in addition, existing sublance composite probe for stainless steel smelting furnace all adopts cement as the liquid inlet port cover closing material, during sampling, sometimes can not burn fully, molten stainless steel, the slag viscosity is bigger again, the part molten stainless steel can condense in has dwindled the liquid inlet port inlet-duct area in the liquid inlet port import, making and can not successfully take a sample by smooth and easy feed liquor that the reason of this two aspect has greatly influenced comprehensive raising and the ordinary production of surveying into rate, is medium-term and long-term existence of stainless steel smelting and AOD stove and the difficult problem that needs to be resolved hurrily.
Summary of the invention
The objective of the invention is to for the not enough sublance composite probe that uses in a kind of stainless steel smelting that is suitable for one-sided oxygen blast mode and the AOD stove that provides of prior art is provided.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of sublance composite probe for stainless steel smelting furnace, comprise the ceramic head that is provided with temperature sensor, middle paper tube, outer paper tube and the docking apparatus that flexibly connects with survey rifle head, in middle paper tube, be provided with by sampling box, the sampling assemble that sampling hut and the sampling liquid inlet port that is communicated with the sampling hut are formed, the import of sampling liquid inlet port is provided with the liquid inlet port capping, it is characterized in that: be provided with reinforced pipe in the described outer paper tube after the paper tube, the reinforced pipe lining is located at after the interior middle paper tube of outer paper tube, reinforced pipe docks with middle paper tube, described reinforced pipe external diameter and outer paper tube internal diameter interference fit, described reinforced pipe is a metal tube.
As the further setting of the present invention: described liquid inlet port capping is made of the papery pipe, and internal diameter and outer paper tube external diameter interference fit are set on the outer paper tube corresponding liquid inlet port inflow point with liquid inlet port import capping.
Compared with prior art, the invention has the beneficial effects as follows: owing to be provided with reinforced pipe after the interior middle paper tube of paper tube outside, strengthened the rupture strength of the body of a gun widely, simultaneously on the other hand, because the raising of body of a gun rupture strength, can be with inside and outside paper tube tube wall attenuate, integral diameter has dwindled, the side force that the body of a gun is subjected to during oxygen blast further reduces, and therefore more difficult fractureing solved the difficult problem that use fractures in stainless steel smelting; And the liquid inlet port capping is made of the papery pipe, can become grey shape fully under the burning of molten stainless steel high temperature, can not get lodged in to dwindle the liquid inlet port inlet-duct area in the liquid inlet port import, thereby make and can successfully take a sample by smooth and easy feed liquor.
Description of drawings
Accompanying drawing 1 is a specific embodiment of the invention structure cut-open view.
