Description
Technical field
The utility model relates to the rotary hanger of muffle tube in a kind of annealing furnace.
Background technology
Anneling production line generally includes and enters to steel band from steel band and leave and comprise the seal casing that is arranged on the entrance, Muffle furnace, cooling section and backward channel successively.Wherein Muffle furnace comprises body of heater, is arranged on the muffle tube in the body of heater and is arranged on the combustion chamber that body of heater is used for heating furnace body outward; Muffle tube is the important workpiece of Muffle furnace, is the barrier of protective atmosphere and burner hearth and heater element.The top flange of Muffle furnace body of heater and cooling section bolted connection, and adopt the silicone rubber O-ring sealing between the two, in the unsettled insertion seal casing in the bottom of Muffle furnace body of heater, charge into quench hot oil in the seal casing casing, to cut off muffle tube and combustion chamber.Needing the operation scheme of annealed strip is upstriker, promptly is with steel to enter from the stove bottom, comes out from stove top, arrives backward channel by the cooling section slewing rollers.
The bottom-to-top-height of large-scale anneling production line can reach 56m, and can handle width is that 650-1350mm, thickness are the stainless steel sheet strip of 0.2-3.0mm.Muffle furnace is the key equipment that guarantees the stainless steel band lightization; the size of muffle tube is big in the Muffle furnace; leading dimensions is φ 1800mm * 27939mm; weight is big; weight is 18000kg during leading dimensions; service conditions is abominable; the inner 100%H2 protective atmosphere of filling during annealing; outside adopt 40 LPG combustion gas or natural fuels burners that arrange according to certain rule and that be symmetrically distributed in body of heater 180 degree both sides to come the heating muffle body of heater; normal working temperature in the Muffle furnace is 1095-1150 ℃; maximum operating temperature can reach 1200 ℃, and whether its normal operation directly has influence on the quality and the output of stainless steel sheet strip bright annealing.
The upper flanges of muffle tube is connected with cooling section, can not upwards expand in heat process, and the lower end is inserted in the oil-sealing sleeve.By design, in heat process, allow horse not freely to extend downwards, and when being elongated to certain-length, should cut off unnecessary muffle tube.Be prevented from if freely extend, then be easy to bend because of certain reason bottom.Secondly, the heating burner is that the length direction along muffle tube is distributed in the muffle tube both sides, thereby if both sides burner combustion ability can not meeting in full accord and the asymmetric elongation difference that causes each section of thermal stress that causes muffle tube to produce, causes bending.This flexural deformation sees it is to be the banana sigmoid on the whole, and its middle part maximum deflection amount can reach 200mm.After the muffle tube deflection was big, the interval between distortion place and the body of heater diminished, and the flame on the burner can directly burn the muffle tube body, and muffle tube is burnt, and caused safety misadventure or equipment downtime accident.
In order to prolong the service life of muffle tube, prevent the overflexing distortion of muffle tube, therefore after muffle tube uses a period of time, need come out the muffle tube integral hoisting, carry out after 180 ° of rotations in installing back Muffle furnace.This hoisting process step is as follows: 1, shift out band steel in the stove earlier; 2, dismounting cooling section and body of heater section flange face tie bolt; 3, remove cooling section equipment; 4, a flange face suspender is installed, is hung out muffle tube to secondary lifting flange face place; 5, secondary flange face suspender is installed, is hung out muffle tube; 6, muffle tube is put on the ground is rotated; 7, lift again after the rotation, muffle tube is put into Muffle furnace.Lifting muffle tube period of service is very long, and the production of company is brought very big influence.
Summary of the invention
Technical problem to be solved in the utility model is that the present situation at prior art provides a kind of the needs that muffle tube is hung out the muffle tube rotary hanger that can be rotated operation in the Muffle furnace to muffle tube, to reach the purpose that shortens muffle tube lifting and rotational time, rotates Muffle furnace safely and fast, enhances productivity.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this muffle tube rotary hanger is characterized in that comprising:
Connecting panel is used to connect the flange of muffle tube upper end, is provided with bolt hole corresponding to the screw on the flange of described muffle tube upper end on the connecting panel;
Hanger is connected on the described connecting panel, is used to connect the suspension hook of lifting appliance;
Connecting device is used to connect described connecting panel and hanger.
Adopt muffle tube rotary hanger provided by the utility model, with the flange of connecting panel bolt together to the muffle tube upper end, make muffle tube unsettled by the lifting appliance that is connected with hanger then, the rotation muffle tube rotates to the rotation that muffle tube can be finished in suitable position, no longer need muffle tube is hung out Muffle furnace, shorten the lifting and the rotational time of muffle tube greatly, improved production efficiency, safe.
Described connecting device can comprise the shackle plate and the connecting rod that is connected described connecting panel and shackle plate that is positioned at described connecting panel top, and described connecting rod and described connecting panel are for captiveing joint.
As improvement, described connecting rod connects described shackle plate rotationally, like this, can finish the rotation of muffle tube by artificial rotary connection plate, has reduced the requirement to lifting appliance.
Preferably, described connecting rod passes described shackle plate, and is connected by bearing between described connecting rod and the shackle plate, and this design not only connects firm, and the rotation between connecting rod and the shackle plate is light, sliding smooth.
Compared with prior art, adopting muffle tube rotary hanger provided by the utility model not need that muffle tube is hung out Muffle furnace can be rotated muffle tube apace, the work capacity and the labour intensity of plant maintenance have been reduced, prolonged the period of inspection and repair of muffle tube, saved maintenance cost greatly, saved production time, good in economic efficiency.
