Embodiment 1

[0044] First, prepare two industrial pure titanium plates with a width of 1200 mm and a length of 100 mm, both of which are half the thickness of the titanium coil, and prepare two stainless steel plates with the same thickness and width at the same time; one end of the stainless steel plate is cut out by laser 9 trapezoidal notches, the upper bottom of the trapezoidal notches is 100mm, the lower bottom is 50mm, the notch depth is 60mm, the distance between adjacent trapezoidal notches is equal to 160mm plus the thickness of the titanium plate, and the shape of the part between adjacent trapezoidal notches is an inverted trapezoid; Do the same, i.e. make the same notches. Secondly, along the notch of the titanium plate and the stainless steel plate and the edge of the inverted trapezoid between the notches, the groove is processed by grinding, and the groove angle is 45°. Again, a press is used to press the inverted trapezoid of the titanium plate into the gap of the stainless...

Embodiment 2

[0048] First, prepare two industrial pure titanium plates with a width of 1050mm and a length of 100mm, the thickness of which is half of the titanium coil; prepare two stainless steel plates with the same thickness and width;

[0049] One end of the titanium plate is cut with 11 T-shaped notches by laser. The long side of the T-shaped notch is 60mm, the short side is 30mm, the depth of the notch is 20+20mm, and the distance between adjacent trapezoidal notches is 90mm. The shape of the part is an inverted T shape; the same treatment is carried out on the stainless steel plate, that is, the same notch is made. Secondly, along the notch of the titanium plate and the stainless steel plate and the edge of the inverted trapezoid between the notches, the groove is processed by grinding, and the groove angle is 60° and 30°; the inverted trapezoid of the stainless steel plate is moved along the groove by a press Pressed into the gap of the titanium plate, at the same time, the invert...

Abstract

The invention discloses a method for manufacturing a transition leading tape for rolling a dissimilar metal connecting structure and a titanium coil, relates to the field of metallurgy, and firstly solves the problem that after existing dissimilar metal which is difficult to weld is connected, the thicknesses of connecting parts are unequal, and related equipment is possibly damaged. According to the technical scheme, the dissimilar metal connecting structure comprises at least two layers of connecting pieces arranged in a stacked mode, each layer of connecting piece comprises a first connecting plate and a second connecting plate which are mutually embedded, the at least two layers of connecting pieces are stacked to form a connecting body, the first connecting plates of every two adjacent layers of connecting pieces are connected in a welded mode, and the second connecting plates of every two adjacent layers of connecting pieces are connected in a welded mode. The first connecting plates and the second connecting plates are mechanically connected through mutual embedding of notches and protruding bodies, and the stress requirement between the two connecting plates is guaranteed. The first connecting plates are titanium plates, the second connecting plates are stainless steel plates, and the connecting body formed by stacking the connecting pieces is the transition leading tape for titanium coil rolling and can be used for titanium coil rolling production.

Description

technical field [0001] The invention relates to the field of metallurgy, in particular to a connection structure of dissimilar metals that are difficult to weld, and a transition leader used when steel plates are switched to titanium plates on a collinear production line between titanium and steel and a manufacturing method thereof. Background technique [0002] In the rolling production of titanium coils, it is a common practice to use rolling equipment to produce titanium coils, and the use of stainless steel leaders can reduce costs. After the titanium coil is connected to the stainless steel leader belt, the connecting joint needs to transmit a large tension and experience the high temperature of the annealing furnace at the same time during the intermediate annealing process. [0003] Conventional welding methods cannot be used to connect titanium coils and steel strips, because the physical and chemical properties of titanium and steel are quite different. When titani...
