Drawings
Fig. 1 is a schematic diagram illustrating the principle of the method for detecting the deviation of the slab in the heating furnace, wherein the arrow direction indicates the running direction of the slab.
Detailed Description
The structure, operation, and the like of the present invention will be further described with reference to the accompanying drawings.
Referring to fig. 1, the heating furnace 1 includes a feeding end 2 and a discharging end 3 for the slab to pass in and out, and further includes a fixed beam 4 and a walking beam 5, the fixed beam 4 is used for supporting the slab, the walking beam 5 is used for driving the slab to advance, and the working principle is as follows: firstly, the walking beam 5 ascends to lift the slab away from the fixed beam 4 and drive the slab to move forward one step towards the side close to the discharge end 3, then the walking beam 5 descends, and the slab descends to the fixed beam 4 along with the walking beam 5, thereby completing a stepping period.
The method for detecting the deviation offset of the plate blank in the heating furnace comprises the following steps:
step one, erecting a total station 6 on one side of a feeding end 2, centering and leveling. In particular, a total station 6 may be erected on a fixed apparatus outside the heating furnace 1, near the feed end 2.
In the second step, a reference point a is selected on the side of the discharge end 3, and similarly, the reference point a may be selected as a point on a fixture located outside the heating furnace 1 and near the discharge end 3. The connecting line direction of the measuring station O where the total station 6 is located and the reference point A is parallel to the running direction of the slab.
And step three, arranging first target paper 8 with a light reflecting function on the datum point A, putting the plate blank 7 to be detected into the feeding end of the heating furnace 1, arranging a target point B on the plate blank 7 to be detected, and arranging second target paper 9 with a light reflecting function on the target point B. The target paper with the light reflecting function is adopted, so that the precision of data acquisition of the total station 6 can be improved. As shown in fig. 1, a base 10 is provided below the second target sheet 9, and the base 10 has a magnetic bottom surface that can be attracted to the blank. Of course, other conventional fixing means can be adopted for the base 10.
And fourthly, acquiring an initial horizontal angle alpha between a connecting line of the measuring station O and the datum point A and a connecting line of the measuring station O and the target point B and an initial distance L1 from the measuring station O to the target point B by using the total station 6. Wherein the initial horizontal angle alpha is the included angle of the two connecting lines when the plate blank 7 to be measured is at the feeding end 2.
And step five, after the walking beam 5 steps for at least one stepping period, acquiring a stepped horizontal angle beta between a connecting line of the measuring station O and the reference point A and a connecting line of the measuring station O and the target point B and a stepped distance L2 between the measuring station O and the target point B by using the total station 6. Wherein the horizontal angle β after stepping is the angle between the two connecting lines after the walking beam 5 is stepped. According to different precision requirements, the frequency of data acquisition by the total station 6 can be selected, i.e. data acquisition is performed once after each step of the walking beam 5 by one period to obtain data with higher precision, or data acquisition is performed once after each step of the walking beam 5 by several periods to obtain data with lower precision.
Preferably, the method for measuring the initial horizontal angle α and the stepped horizontal angle β may be a method of measuring a return. Of course, directional observation may also be used.
And sixthly, calculating the deviation delta d of the plate blank 7 to be detected according to data collected by the total station 5, wherein the data comprises an initial horizontal angle alpha, an initial distance L1, a stepped horizontal angle beta and a stepped distance L2.

Δd=L1sinα-L2sinβ。
the offset delta d can be calculated automatically through a PLC (programmable logic controller), specifically, the total station 6 is connected with a PLC (not shown in the figure), the total station 6 transmits the acquired data to the PLC, and the PLC calculates the offset delta d of the deviation of the plate blank 7 to be measured according to the data.
The slabs with different tonnages can be sequentially placed into the heating furnace 1, and the deviation delta d of each slab is measured simultaneously by adopting the detection method for the analysis of workers.
According to the method for detecting the deviation offset of the plate blank in the heating furnace, data information of a target point B on the plate blank 7 to be detected before and after stepping of the walking beam 5 is collected through a total station, and the collected data is transmitted to a PLC (programmable logic controller) for calculation, so that the deviation offset delta d of the plate blank 7 to be detected is obtained.
