Described trilateral heating zone is row's trilateral heating zone, the outer edge that they lay respectively at described upper and lower limb plate is the non-core side of web, the apex height of described trilateral heating zone is respectively greater than 1/2 of upper and lower limb plate width, and the base of described trilateral heating zone is the outward flange of described upper and lower limb plate; Concentrate and be heated to 700-800 ℃, promptly be heated the district and be garnet;
If heating does not once reach the shaping requirement, then repeat heating, repeat to heat the position and open with heating part dislocation before.
B, when side bending deformation is pointed to the core side of web, the upper and lower limb plate of described folder is carried out the heating method of trilateral heating zone respectively; Web to described folder carries out vertical wire heating simultaneously;
Described trilateral heating zone is row's trilateral heating zone, they lay respectively at the edge of the close web of described upper and lower limb plate, greater than 1/2 of the width of upper and lower limb plate, the base of described trilateral heating zone is the boundary line of upper and lower limb plate and web to the apex height of described trilateral heating zone respectively; Concentrate and be heated to 700-800 ℃, promptly be heated the district and be garnet;
To the vertical wire heating of described web, promptly vertical linear heating zone is corresponding with the trilateral heating zone on being positioned at described upper and lower limb plate, concentrates 700-800 ℃ of heating, promptly is heated the district and is dark red;
If heating does not once reach the shaping requirement, then repeat heating, repeat to heat the position and open with heating part dislocation before.
Positively effect of the present invention is to have solved the side bending deformation problem that transformer core clamping welding back occurs preferably, and shaping effect is better, and this method is simple.
