TABLE 1 position of sensor relative to positioning block positioning surface
| Sensor with a | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 |
| Distance between two adjacent plates | 450 | 950 | 1420 | 1920 | 2320 | 2920 | 3280 | 3920 | 4320 | 4720 | 5270 | 5770 |
The length detection principle is explained by taking a detection process of a 5m long continuous casting billet as an example: when the length detection sensor 3-3 positioned at the 4720mm position of the continuous casting billet positioning end detects that a continuous casting billet exists, the length of the continuous casting billet is not less than 5 m; when the length detection sensor 3-3 positioned at the 5270mm position of the continuous casting billet detects no continuous casting billet, the length of the continuous casting billet is not more than 5.5m, and the length of the finally obtained continuous casting billet is 5 m.
Table 2 summarizes the detection conditions of all the continuous casting billets, wherein 0 represents that the sensor does not detect the continuous casting billets, and 1 represents that the sensor detects the continuous casting billets.
TABLE 2 continuous casting billet Length detection sensor Signal Table
The basic principle of the continuous casting billet section detection is to judge whether a billet exists or not. The cross section size of the continuous casting billet is 150mm multiplied by 150mm, and 180mm multiplied by 180mm is taken as an example. Because the heights of the two cross-section sizes in the vertical direction are different, the cross section of the steel billet can be judged according to the vertical size of the cross section. When the section specification detection sensors 1-11 move downwards to a height of 200mm from the upper part of the table top of the cutting workbench 3, if a continuous casting billet is detected, the section size of the continuous casting billet is 180mm multiplied by 180mm, and otherwise, the section size of the continuous casting billet is not 150mm multiplied by 150 mm. When the section specification detection sensor 1-11 continuously moves downwards to a height 170mm from the upper part of the table surface of the cutting workbench, if a continuous casting billet is detected, the section dimension of the continuous casting billet is 150mm multiplied by 150 mm.
The positions for detecting 5 specifications of the continuous casting slab are shown in table 3.
