Gradient heating device and method for titanium/austenitic stainless steel composite plate

A gradient heating device for a titanium/austenitic stainless steel composite plate, comprising:

• a first support frame, wherein a heating box is arranged on the first support frame;
• a second support frame arranged inside the heating box;
• a pair of clamps relatively slidably arranged inside the heating box, wherein the pair of clamps are configured to clamp a titanium steel composite plate, and the pair of clamps are respectively provided with a positive electrode interface and a negative electrode interface;
• a pulse power supply arranged on the heating box, wherein the pulse power supply is connected to the positive electrode interface and the negative electrode interface;
• a pressing plate slidably arranged on the second support frame, wherein the pressing plate is configured to abut against a steel side of the titanium steel composite plate;
• a magnetic field generator arranged on the second support frame, wherein the magnetic field generator is connected to the pulse power supply;
• and
• a cooling plate arranged on the first support frame, wherein the cooling plate is configured to abut against a titanium side of the titanium steel composite plate, a cooling fluid flows inside the cooling plate, and the cooling plate is in communication with a cooling fluid circulation and condensation system.
