Problems solved by technology

[0002] Copper foil is made of copper plus a certain proportion of other metals. Aluminum foil products of different specifications and thicknesses have been widely used in packaging, aviation, electromechanical and other fields. However, the copper foil rolling technology is not mature enough. The rolling mill is still in the research and development stage, so the copper foil products are not yet available in the market
[0003] A six-roll copper foil rolling mill in Japan can roll out copper foil products with a thickness of less than 10 μm, but the working rolls of this copper foil rolling mill are smaller in size, the diameter of the finished product is less than 150mm, and the slenderness ratio is greater than 17

preparation example Construction

[0019] The preparation steps of the work roll are as follows:

[0020] Steel is first refined, and steel billets are manufactured to make the chemical composition and content of the steel reach the required range, and the cold-rolled billet is manufactured by conventional production technology. Cast the electrode, then anneal the electrode ingot, melt and cast the electrode ingot into an electroslag ingot, and finally test it. After the composition is qualified, the electroslag ingot is heated, forged into a forging billet, heat treated for the forging billet, and finally turned (rough turning ), after passing the inspection, carry out quenching and tempering treatment (preparation heat), the quenching and tempering treatment is carried out in a resistance furnace, the heating temperature is 850-880°C, and the holding time is 6-8h;

[0021] Then induction hardening is carried out. The heating temperature during induction hardening is 910-980°C, the quenching speed is 50-100mm / ...

Abstract

The invention discloses a working roller of a copper foil rolling machine and belongs to the field of preparation of rollers. The working roller is prepared from the following chemical components in percentage by weight: 0.7 to 1.0 percent of C, 0.2 to 1.0 percent of Si, 0.1 to 0.6 percent of Mn, 1.5 to 3.5 percent of Cr, 0.1 to 0.8 percent of Mo, less than or equal to 0.6 percent of Ni, less thanor equal to 0.5 percent of V, less than or equal to 0.02 percent of P and less than or equal to 0.02 percent of S. The working roller disclosed by the invention has the advantages of high hardness and high hardness uniformity; the thickness of a rolled copper foil can reach 10mu m or lower.

Description

technical field [0001] The invention relates to copper foil rolling equipment, in particular to a copper foil rolling mill work roll, which belongs to the field of roll preparation. Background technique [0002] Copper foil is made of copper plus a certain proportion of other metals. Aluminum foil products of different specifications and thicknesses have been widely used in packaging, aviation, electromechanical and other fields. However, the copper foil rolling technology is not mature enough. The rolling mill is still in the research and development stage, so the copper foil products are not yet available in the market. [0003] A six-roll copper foil rolling mill in Japan can roll copper foil products with a thickness of less than 10 μm, but the working rolls of this copper foil rolling mill are smaller in size, the diameter of the finished product is less than 150mm, and the slenderness ratio is greater than 17. To roll copper foil products that meet the requirements, t...
