Description
Technical Field
The invention relates to the field of cold-rolled strip steel galvanizing equipment, in particular to a cold-rolled strip steel passivation near-infrared heater lamp tube arrangement structure.
Background
The steel production refers to that iron ore, coke and cosolvent are sintered and smelted in a blast furnace to form molten iron, the molten iron is desulfurized and dephosphorized, then is subjected to process treatment such as converter blowing and the like, is cast by a continuous casting machine to form a billet semi-finished product, and then is sent to rolling production lines such as hot rolling, cold rolling and the like to be made into plate and wire products. The cold rolling process is to use the steel coil after hot rolling treatment as a raw material, remove oxide skin by acid washing, carry out cold continuous rolling to form a hard rolling coil, carry out degreasing by a galvanizing unit and reduction annealing by a continuous annealing furnace on the hard rolling coil, carry out hot galvanizing treatment in a zinc pot, quickly cool strip steel by a cooling tower, straighten the strip steel by a straightening machine, carry out chromium passivation and infrared heating curing treatment on the straightened strip steel in a passivation tank, and finally cut and coil to obtain the galvanized finished steel coil. The chromium passivation of the strip steel is to form a protective layer, namely a chromium passivation film with a certain film thickness on the surface of the strip steel by using a passivation solution under an oxidation condition, and heat and solidify the passivation film through a left door and a right door of a near infrared heater, so as to prevent the galvanized strip steel from generating white rust by oxidation. The cold-rolled galvanized strip steel with the chromium passivation solution vertically passes through a left door and a right door of a lower near-infrared heater and a left door and a right door of an upper near-infrared heater from bottom to top, a chromium passivation film on the surface of the strip steel can be rapidly solidified under the heating action of the four near-infrared heaters, and a cooling fan is used for cooling an air duct of a box body of the near-infrared heater and the outside. In the production process, the near-infrared heater hot area heats the strip steel to about 500 ℃, the peak point can reach about 1000 ℃, the lamp tube heat-resistant wire and the lamp holder in the hot area are rapidly aged frequently, and the lamp holder burst accident frequently occurs in the heating process, so that individual lamp tubes are damaged. Meanwhile, because the near-infrared lamp tube is vertically installed, the filament in the lamp tube drops to form an S shape under the action of long-term high temperature and gravity, and the filament touches the glass tube wall of the lamp tube, so that the local high temperature deformation bulges and air leakage can cause the damage of the lamp tube. In the near-infrared heater, because the running direction of the strip steel is consistent with the installation direction of the lamp tubes and is vertical, when the near-infrared lamp tubes are damaged, the passivating liquid coating on the surface of the strip steel passing through the coverage area of the lamp tubes cannot be stably solidified, thereby causing the product quality problem of the cold-rolled strip steel.

Fig. 2 is a schematic view of the heating cabinet of the present invention when it is unfolded.
Labeled as: the device comprises a strip steel 1, a strip steel running direction 11, a near-infrared lamp tube 2, a lamp holder 21, a filament 22, a cold zone partition plate 3, a cooling air blowing device 4, a heating box body 5, a heating box body rotating track line 7, a cold zone 8 and a hot zone 9.
Detailed Description
The invention is further described below with reference to the accompanying drawings.
The lamp tube arrangement structure of the cold-rolled strip steel passivation near-infrared heater shown in fig. 1 and fig. 2 comprises at least two near-infrared lamp tubes 2 and strip steel 1, and comprises a strip steel running direction 11 when the strip steel 1 is conveyed forwards, wherein the central axis direction of the near-infrared lamp tubes 2 is perpendicular to the strip steel running direction 11. Therefore, when a certain near-infrared lamp tube 2 is damaged, the passivation area of the strip steel can be always in the coverage area of other normally working near-infrared lamp tubes, and the phenomenon of strip leakage can not occur.
In order to adapt to the structure of the transport path of the steel strip 1 and thus to achieve heating of the upper and lower surfaces of the steel strip 1, the following solution is preferred: the strip steel conveying device comprises a pair of heating box bodies 5, wherein a strip steel 1 conveying channel is arranged between the heating box bodies 5, and a near-infrared lamp tube 2 is arranged on the inner wall surface of each heating box body 5. As shown in fig. 2, the heating box 5 is rotatably provided on the conveying track of the strip steel 1, and the heating box 5 rotates along the heating box rotating track line 7. During actual heating, the near-infrared lamp tubes 2 on the inner wall surface of the heating box body 5 are respectively arranged on two sides of the upper surface and the lower surface of the strip steel 1.
In order to effectively distinguish the hot zone 9 where the heating zone is located from the cold zone 8 where the cold temperature is needed, thereby effectively protecting the relevant equipment devices, the following scheme is preferred: the inner wall surface of the heating box body 5 is provided with a pair of cold zone partition plates 3, the area between the pair of cold zone partition plates 3 is a hot zone 9, and the area outside the pair of cold zone partition plates 3 is a cold zone 8. In order to ensure the effectiveness of temperature insulation, the cold zone partition 3 and the near-infrared lamp tube 2 are preferably arranged vertically to each other. In the production process, the temperature-resistant wire and the lamp holder of the near-infrared lamp tube 2 in the hot zone 9 are frequently and rapidly aged, and the lamp holder burst accident frequently occurs in the heating process, so that individual lamp tubes are damaged. Meanwhile, the filament in the near-infrared lamp tube 2 falls down to form an S shape under the action of long-term high temperature and gravity, and the filament touches the glass tube wall of the lamp tube, so that the local high temperature is deformed, bulges and leaks, and the lamp tube is damaged. When the near-infrared lamp tube 2 is damaged, the passivating liquid coating on the surface of the strip steel passing through the coverage area of the lamp tube cannot be stably solidified, so that the product quality problem of the cold-rolled strip steel is caused. Therefore, in order to overcome the above-mentioned drawbacks, it is preferable that the bases 21 at both ends of the near-infrared lamp 2 are disposed in the cold zone 8, and the filament 22 at the middle of the near-infrared lamp 2 is disposed in the hot zone 9. In actual use, in order to ensure that the temperature of the cold area 8 is at a low level, thereby prolonging the service life of the temperature-resistant wire and the lamp head 21, the cold area 8 is preferably provided with a cooling air blowing device 4.
In order to avoid the filament 22 of the near-infrared lamp tube 2 from falling under the action of long-term high temperature and gravity and reduce the damage of the lamp tube caused by short circuit of the filament, the central axis direction of the near-infrared lamp tube 2 is preferably parallel to the horizontal plane, i.e. horizontally arranged. Correspondingly, the near-infrared lamp tube 2 is arranged on the inner wall surface of the heating box body 5 through the ceramic fixing buckle, so that the near-infrared lamp tube 2 is ensured to be in a stable state.
