preparation example Construction

[0020] Specifically, as figure 1 As shown, the method for preparing rolled foil using a double-sided cladding plate according to a preferred embodiment of the present invention comprises:

[0021] The first step S1 is to cut two wrapping plates whose size is consistent with that of the foil blank; for example, the thickness of the foil blank is 1-0.05 mm; preferably, the thickness of the wrapping plate is 1.0-2.0 mm.

[0022] Preferably, the material of the foil blank is tungsten-nickel-iron, tungsten-nickel-copper, tungsten-copper, molybdenum-copper, pure molybdenum, pure tungsten and other materials. For example, the foil stock can also be a copper alloy stock.

[0023] Preferably, the cladding plate is an economical plate with good welding performance, such as iron plate, copper plate, aluminum plate, stainless steel plate, etc. For example, the cladding plate is a cladding iron plate.

[0024] In the second step S2, the two cut-out wrapping plates are respectively wrapp...

Embodiment 1

[0030] The 85Mo-Cu composite material with a size of 0.1mm*149*150 is double-sided coated with a sheathed iron plate. The thickness of the sheathed iron plate is 1.5mm. It is 1000r / min, the pressure is within 30t, and the pass reduction is 0.002-0.005mm. When the length is extended to 600mm, stop rolling. According to the principle of constant volume, the thickness of molybdenum-copper is 0.025mm at this time. The actual measured thickness is 0.024mm, and the thickness tolerance is within ±0.002mm. The surface of the style is smooth, without waves and cracks.

Embodiment 2

[0032] Cover the iron plate with pure Mo with a size of 0.05*175*192mm, the thickness of the iron plate is 2mm, and wrap it on a two-roll rolling mill. The diameter of the roll is 300mm, the speed of the roll is 1500r / min, and the pressure is Within 30t, the pass reduction is 0.002-0.005mm. When the length is extended to 385mm, stop rolling. According to the principle of constant volume, the thickness of molybdenum-copper should be 0.025mm at this time. The actual measured thickness is 0.026mm, and the thickness tolerance is within ±0.002mm. The surface of the style is smooth, without waves and cracks.

Abstract

The invention provides a preparation method by employing double-face coated jacketing plates to roll a foil. The preparation method comprises the steps that Step one, two jacketing plates of which the sizes are consistent with that of a coil blank are cut; Step two, the two faces of the coil blank are coated with and welded to the cut two jacketing plates respectively, so as to form a coated coil blank; and Step three, according to the expected thickness of the foil, the coated coil blank is rolled to form a coil sheet. In the step two, the peripheries of the jacketing plates are welded to the periphery of the foil blank, so that the edges of the jacketing plates are welded to the corresponding edge of the foil blank together. In the third step, during rolling, according to the volume constant principle, by measuring the real-time length of the coated foil blank, the coated foil blank is rolled till the foil sheet reaches the required thickness.

Description

technical field [0001] The invention relates to the technical field of pressure processing, and more specifically, the invention relates to a preparation method for rolling a foil material by using double-sided cladding plates. Background technique [0002] Metal foil rolling has very high requirements for equipment, large-scale equipment, high requirements for production workshops, and high requirements for funds. For small varieties of metals, there is neither such a large market scale nor such a large amount of capital for production companies, and there are more constraints on the front and rear processes. With the application of LED chip-level packaging, heat sink, laser, microwave communication and other fields, the demand for foil materials such as tungsten copper, molybdenum copper, pure Mo, pure W, tungsten alloy, etc. is increasing. The preparation is a problem that enterprises must face. [0003] The normal rolling process can generally produce materials with a ...
