Embodiment
Describe in further detail below in conjunction with the embodiment of accompanying drawing the utility model.
See Fig. 1, Fig. 2, Fig. 3, Fig. 4; A kind of device of measuring the converter lining corroding thickness; Comprise right angle frame 7, fixed ruler 5, adjustable rule 10, steel cable 4, limiting plate 2, described fixed ruler 5 and adjustable rule 10 are separately positioned on two square edges of right angle frame 7, and fixed ruler 5 one ends contact with limiting plate 2; Fixed ruler 5 inner chambers are provided with steel cable 4, and an end of steel cable 4 is connected with limiting plate 2; The other end is connected with adjustable rule 10; The square edge outer ledge that described right angle frame 7 is provided with adjustable rule 10 is provided with backup plate 8; Right angle frame 7 adopts rotating shaft 9 to be connected with adjustable rule 10; Adjustable rule 10 can be that 0 °～90 ° rotation is done with respect to fixed ruler 5 in the center with rotating shaft 9, and fixed ruler 5 lower ends are provided with support limit stop 11, and limiting plate 2 one sides are provided with draw ring 1; Another side adopts set collar 3 to be connected with steel cable 4, and right angle frame 7 adopts the mode of welding to be connected with fixed ruler 5, is provided with steel cable slide bar 6 in the inner chamber of the end that fixed ruler 5 is connected with right angle frame 7.
The method of use of this device is:
1) at first adjustable rule 10 being rotated to respect to fixed ruler 5 is 0 ° position, then this device is put in the converter through the converter opening, decontrols adjustable rule 10 again, and tension draw ring 1 makes adjustable rule 10 and fixed ruler 5 rectangular;
2) support limit stop 11 is stuck in converter and keeps off place, 13 doorways, fiery gate; Measure the vertical range h on platform 12 ground, fixed ruler 5 end-to-end distance stokehold; Be the axle center with support limit stop 11 then, on lift fixed ruler 5, make adjustable rule 10 bottoms and converter corrode that tested point contacts on the rear inner lining 15.At this moment, measure the vertical range y on platform 12 ground, fixed ruler 5 end-to-end distance stokehold;
3) setting corroding thickness to be measured is x; The original liner distance of setting fixed ruler 5 upper limbs to converter tested point is H; Set two segment distances of being cut apart by the fiery gate 13 of retaining on the fixed ruler 5 and be respectively R, r, as shown in Figure 4, the vertical displacement that raw bits fixed ruler 16 rotates to be when measuring position fixed ruler 17 is x
1, the distance of setting between raw bits fixed ruler 16 lower rims to the converter erosion rear inner lining 15 is removed x again
1After distance be x
2, then with R, r, H, h substitution formula:
Corroding thickness then
Because R, r, H, h value have been measured when opening new furnace, and record the y value in the actual production process, with R, r, H, h, y value substitution following formula, can obtain converter lining workplace corroding thickness x value.
