When being with steel to be used for Important Project or the high field of the surface requirements such as automobile, household electrical appliances, high requirement is just had for Surfaces of Hot Rolled Strip quality control; Surfaces of Hot Rolled Strip has not allowed obvious iron scale to be pressed into defect under normal circumstances.Be all utilize high-pressure spray to spray dephosphorization in prior art, before pony roughing mill group and finishing stand group, be all provided with the iron scale that a dephosphorization case removes belt steel surface avoid forming impression in the operation of rolling; Find during actual production, often residual a part of iron scale chip in dephosphorization case, this part chip can splash down back surface of steel plate, will be pressed into band steel like this, become secondary and be pressed into iron scale, have impact on product quality through rolling first frame.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of hot-strip roughing district and aspirates the iron scale fragment that online dephosphorization apparatus utilizes the falling of calibrator discovery secondary, then removes with suction port of bleeding and directly takes iron scale chip away; Suction port of bleeding is normally off and only arranges at upper surface, only just can open dust suction when finding secondary oxidation iron sheet, substantially the temperature of steel plate being had no effect, both ensure that strip surface quality, the stability of rolling accuracy can be ensured again, improve the overall performance of band steel.
The utility model is achieved in that online dephosphorization apparatus is aspirated in a kind of hot-strip roughing district, heating furnace has been disposed in order according to the direction of advance of steel plate, roughing dephosphorization case, pony roughing mill group, finish rolling dephosphorization case and finishing stand group, be provided with between described roughing dephosphorization case and pony roughing mill group and be with steel thickness measurement online instrument, suction port of bleeding is provided with between described band steel thickness measurement online instrument and pony roughing mill group, described band steel thickness measurement online instrument is connected with controller, described suction port of bleeding is arranged on lifting support, suction port of bleeding is connected with aspiration pump by exhaust pipe, described controller control connection aspiration pump, described lifting support drives suction port vertical lift of bleeding make the to bleed spacing of suction port and surface of steel plate to remain between 1 ~ 10mm.
Also crop shears are provided with between described pony roughing mill group and finish rolling dephosphorization case.
Described suction port of bleeding is positioned at the upper surface of steel plate, and suction port of bleeding is the strip pump orifice covering steel plate transverse direction.
In described pony roughing mill group every two adjacent passages pony roughing mill between be all provided with one group of dephosphorization winding-up mouth.
In described finishing stand group every two adjacent passages finishing stand between be all provided with one group of dephosphorization winding-up mouth.
Applicant is through examining discovery, the iron scale that secondary falls after rise is all the chip departed from completely with surface of steel plate, adhesion is very little between the two, and different and normal iron oxide cortex, therefore without the need to using the high pressure spray head of large impact power to carry out dephosphorization to this type of chip;
The utility model hot-strip roughing district aspirates online dephosphorization apparatus and utilizes calibrator to find the iron scale fragment that secondary falls after rise, then removes with suction port of bleeding and directly takes iron scale chip away; Suction port of bleeding is normally off and only arranges at upper surface, only just can open dust suction when finding secondary oxidation iron sheet, substantially the temperature of steel plate being had no effect, both ensure that strip surface quality, the stability of rolling accuracy can be ensured again, improve the overall performance of band steel.
Accompanying drawing explanation
Fig. 1 is the structural representation that online dephosphorization apparatus is aspirated in the utility model hot-strip roughing district.
In figure: 1 steel plate, 2 heating furnaces, 3 roughing dephosphorization casees, 4 pony roughing mill groups, 5 finish rolling dephosphorization casees, 6 finishing stand groups, 7 band steel thickness measurement online instrument, 8 are bled suction port, 9 controllers, 10 crop shears, 11 dephosphorization winding-up mouth, 12 aspiration pumps.
Detailed description of the invention
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model statement.
Embodiment 1
As shown in Figure 1, online dephosphorization apparatus is aspirated in a kind of hot-strip roughing district, heating furnace 2 has been disposed in order according to the direction of advance of steel plate 1, roughing dephosphorization case 3, pony roughing mill group 4, finish rolling dephosphorization case 5 and finishing stand group 6, be provided with between described roughing dephosphorization case 3 and pony roughing mill group 4 and be with steel thickness measurement online instrument 7, suction port 8 of bleeding is provided with between described band steel thickness measurement online instrument 7 and pony roughing mill group 4, described band steel thickness measurement online instrument 7 is connected with controller 9, described suction port 8 of bleeding is arranged on lifting support, suction port 8 of bleeding is connected with aspiration pump 12 by exhaust pipe, described controller 9 control connection aspiration pump 12, described lifting support drives suction port 8 vertical lift of bleeding make the to bleed spacing on suction port 8 and steel plate 1 surface to remain between 1 ~ 10mm, the too small conveying that may have influence on steel plate of this spacing, spacing is excessive, and suction force can be caused not enough.
