Embodiment 1

[0011] Example 1: First, use a milling machine to remove the rust and oxide layers of two titanium plates and a steel plate with the same length and width. The material of the titanium plates is TA2, the size is 500mm×200mm×1mm, and the material of the steel plate is 304 austenite Stainless steel, the size is 500mm × 200mm × 10mm; then two titanium plates and a steel plate are removed from the surface of the rust layer and oxide layer, so that they are completely overlapped to form a composite blank of titanium-steel-titanium; and then two pieces of material are TA2, a titanium plate with a size of 500mm×12mm×3mm is used as a side sealing plate to seal the long side of the combined blank, and two titanium plates with a material of TA2 and a size of 200mm×12mm×3mm are used as side sealing plates to seal the combined blank. Wide side; choose 4 steel plates with a size slightly larger than the combined blank as splints, clamp the 4 side sealing plates and the combined blank with b...

Embodiment 2

[0012] Embodiment 2: Utilize the milling machine to remove the rust layer and the oxide layer of two titanium plates and a steel plate with the same length and width, wherein the material of the titanium plate is TA2, the size is 500mm×200mm×1mm, and the material of the steel plate is 304 austenitic stainless steel , with a size of 500mm×200mm×10mm; then put two titanium plates and a steel plate with the surface where the rust layer and oxide layer have been removed facing each other, so that they are completely overlapped to form a composite blank of titanium-steel-titanium; and then use two pieces of material as TA2 , a titanium plate with a size of 500mm×12mm×3mm is used as a side sealing plate to seal the long side of the combined blank, and two titanium plates with a material of TA2 and a size of 200mm×12mm×3mm are used as side sealing plates to seal the width of the combined blank side; select 4 steel plates with a size slightly larger than the combined blank as splints, ...

Embodiment 3

[0013] Example 3: First, use a milling machine to remove the rust and oxide layers of two titanium plates and a steel plate with the same length and width, wherein the material of the titanium plates is TA2, the size is 500mm×200mm×1mm, and the material of the steel plate is 304 austenite Stainless steel, the size is 500mm × 200mm × 10mm; then two titanium plates and a steel plate are removed from the surface of the rust layer and oxide layer, so that they are completely overlapped to form a composite blank of titanium-steel-titanium; and then two pieces of material are TA2, a titanium plate with a size of 500mm×12mm×3mm is used as a side sealing plate to seal the long side of the combined blank, and two titanium plates with a material of TA2 and a size of 200mm×12mm×3mm are used as side sealing plates to seal the combined blank.

Abstract

The invention relates to a preparation method of a composite steel plate, in particular to a preparation method of a titanium-steel composite plate. The preparation method comprises the following steps of: firstly selecting titanium plates and steel plates which have equal width and length and removing rusty layers and oxide layers; then making surfaces of the titanium plates and the steel plates opposite, and completely coinciding to form a combined blank; then sealing up the periphery of the combined blank by taking four titanium plates as side seal plates, and clamping the side seal plates and the combined blank by using a clamp and then putting the side seal plates and the combined blank into a vacuum chamber together; tightly welding all contact seams of the combined blank and the side seal plates, then conveying the combined blank and the side seal plates into a heating furnace together and heating to 600-1200 DEG C, and carrying out heat preservation for 0.1-2h; and finally, conveying the heated combined blank into a rolling mill for rolling to obtain the titanium-steel composite plate with the interface bonding strength of 350MPa. The invention well solves the problem that the interface of the titanium-steel composite plate is oxidized and improves the interface bonding strength of the composite plate, and moreover, argon or brazing filler metal does not need to be added, thereby saving the cost and simplifying the flow of the production process.

Description

technical field [0001] The invention relates to a preparation method of a composite steel plate, in particular to a preparation method of a titanium-steel composite plate. Background technique [0002] Titanium-steel clad plates are widely used in energy, petroleum, chemical and marine industries due to their excellent corrosion resistance and remarkable economy. At present, especially in the field of heat exchangers, it has great application prospects. The heat exchangers used in the past are all made of pure titanium plates. If the pure titanium plates are replaced with titanium-steel composite plates, the cost will be greatly reduced. Therefore, there will be a huge demand on the market for titanium-steel composite panels with large size and thin thickness. There are two main methods of producing titanium-steel clad plates: one is the explosive clad method, and the other is the rolling clad method. The clad plate produced by the explosive cladding method is small in si...
