Description
Technical field
The present invention relates to a kind of device for fixing annealing furnace internal resistance band。
Background technology
Annealing furnace has been the equipment of steel recrystallization annealing, so that steel realizes cooling procedure and overaging process。Annealing furnace is generally made up of preheating section, bringing-up section, soaking zone, slow cooling section, rapid cooling section, overaging section and whole cold section of this 7 part。Wherein, the stove inwall both sides of slow cooling section and overaging section are provided with the resistor promoting steel recrystallization annealing, and for this, in the prior art, a kind of mode installing resistor is to fix special refractory brick on furnace wall, and is hung with resistor on refractory brick；The another kind of mode installing resistor is to utilize the suspended axle and insulator foot that are arranged on stove inwall, and the structure of the nut for fixed insulation base being screwed on suspended axle is to hang resistor。Although the mode that both installs resistor can make steel recrystallization annealing, but because strip steel and equipment can produce vibration when running, its vibration passes to refractory brick or suspended axle parts by furnace shell, even if the nut on refractory brick or suspended axle has quite desirably pretightning force, also easily make refractory brick loosen or suspended axle on nut get loose, so, above two installs the mode of resistor very easily makes it come off；Simultaneously because the thermal coefficient of expansion of suspended axle Yu insulator foot is not the same, so, pretightning force will be produced impact by suspended axle and insulator foot in the process being heated and cool down, thus causing that resistor comes off；Further, since resistor be energized heating and have a power failure cooling time can produce to stretch, displacement and these several situations of deformation, these combined factors together, result in the rotation of suspended axle and exit, thus causing resistor to come off。Topmost problem is, resistor is arranged in the furnace wall of 6 25 meters both sides height vacancy, the process of maintenance resistor is only saved furnace outage time to reduce cost and improve the yield of steel, so, operator can only from furnace roof sit chair lift unsettled in stove, keep in repair resistor, its construction is highly inconvenient, and danger is bigger。
Name disclosed in Chinese patent 102560027A is called that " resistance belt fixing device in vertical annealing furnace " adopts two rows steel bracket to be fixed on abreast on furnace shell, and on each support, bore row's circular hole, each support is in a row fixed anchor rod by circular hole and sets insulating ceramics ring in the fixed end cap of anchor rod, and resistor is suspended on ceramic ring。Although this kind of device is to adopt two rows steel bracket to be fixed by resistor, but due to resistor be energized heating and have a power failure cooling time can produce to stretch, displacement and these several situations of deformation, if fixed by the upper and lower side of resistor, its flexible, displacement and deformation very easily make resistor damage；It addition, because the thermal coefficient of expansion of anchor rod Yu insulating ceramics ring differs, so, adopt two rows steel bracket to fix resistor and also very easily cause that resistor comes off。
Summary of the invention
The purpose of the present invention is to propose to the mode that a kind of utilization prevents transverse bar member from rotating solve resistor come off problem fixing annealing furnace in the device of resistor。
The device of fixing annealing furnace internal resistance band proposed by the invention includes the exhausting hole being arranged on inside furnace shell on insulating part and the transverse bar member being screwed on each through hole, and it is arranged on the insulated porcelain sleeve for hanging resistor in transverse bar member, described transverse bar member is provided with radial direction through hole near the position of insulated porcelain sleeve outer end, and is provided with the location rod member inserted in radial direction through hole between adjacent two transverse bar member。
Described location rod member is made up of stainless steel welding stick。Described location rod member extends the end of radial direction through hole and is provided with kink。
Described insulated porcelain sleeve central region is provided with the axial width toroidal cavity slightly larger than resistor width。
Transverse bar member in the device of fixing annealing furnace internal resistance band proposed by the invention is provided with radial direction through hole near the position of insulated porcelain sleeve outer end, the location rod member inserted in radial direction through hole is adopted adjacent two transverse bar member to be fixed, it produces vibration and swings without rotation being subject to outer bound pair to cause transverse bar member, make it be effectively prevented coming off of insulated porcelain sleeve, and resistor is played reinforcement effect by insulated porcelain sleeve difficult drop-off on the whole。Slow cooling section and the overaging section of annealing furnace adopt this device after testing, and resistor utilization rate can improve more than 6 times；It addition, the structure of this device is very simple, it is substantially free of raising cost of manufacture。
