Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail, but this embodiment should not be construed as limitation of the present invention.
In Fig. 1, the implementation result of the oriented silicon steel coil of strip of prior art is existing in the introduction describes, and does not repeat them here.
See Fig. 2, the present invention scribbles the fixing means of oriented silicon steel when high temperature annealing of MgO coating, comprises the steps:
Step one, see Fig. 3, after steel coil is got, 1 to correct position is taken the lead in adjustment, described correct position be make respectively with take the lead 1 and coil of strip axis 5 perpendicular, be connected and take the lead the line 6 of 1 and coil of strip axis 5 horizontal by α angle, described α < 90 °, in the present embodiment, α=45 °, this angle ensures that follow-up bending trilateral and welding sequence can with the gesture operation of the best;
Step 2, tie (not shown) is cut into the cassette tape 2 that length is 30cm, see Fig. 4, cassette tape 2 is converted into two sections, two segment length are respectively 6 ~ 7cm and 23 ~ 24cm, in the selection insertion point, position 3 enclosing (after ensureing high temperature annealing, coil of strip is still more firm) apart from coil of strip outer ring 6 ~ 10, cassette tape 2 is inserted coil of strip, described insertion point 3 is apart from taking the lead 110 ~ 15cm;
Step 3, see Fig. 5 and Fig. 6, the steel band of taking the lead between 1 and insertion point 3 is bent into trilateral 4 downwards, two square edge length of described trilateral 4 are respectively 10 ~ 15cm and 20 ~ 30cm, wherein, first square edge 4.1 is 10 ~ 15cm, and the second square edge 4.2 is 20 ~ 30cm, and this size can ensure that trilateral 4 can push down cassette tape 2 completely, can ensure again trilateral 4 not reason size cause too greatly the steel band of loss more, cassette tape 2 pushed down by described trilateral 4;
Step 4, adjustment argon welder electric current are 50 ~ 60A, trilateral 4 is welded with cassette tape 2 overlapping part, the interior side contacts point of described trilateral 4 and cassette tape 2 is as interior solder joint 2.1 (butt welding count no requirement (NR)), and the contact outside point of described trilateral 4 and cassette tape 2 is as outer solder joint 2.2 (butt welding count no requirement (NR));
After step 5, welding, check solder joint firmness, if be firmly delivered to subsequent processing by walking beam.
See Fig. 7, can realize without tie, without sleeve after using the present invention; Greatly reduce production cost, simultaneously owing to have employed the present invention, eliminate the situation that coil of strip outer ring produces impression defect, avoid the falling phenomenon produced because steel plate hardness declines in high temperature environments at high-temperature annealing process China and foreign countries astragal head, improve quality product, ensure carrying out smoothly of production.
