Description
Technical Field
The invention belongs to the technical field of non-ferrous metal material processing, and particularly relates to a short-process rolling method of a nickel strip.
Background
Along with the pace of the rise of new energy vehicles, high-purity nickel is widely applied to industries such as power batteries and the like due to the fact that the high-purity nickel has good conductivity, excellent corrosion resistance, excellent strength and plasticity, and the nickel belt and the nickel foil are mainly used for collecting current, guiding current and fixing battery packs or elements (such as connecting sheets, lugs, leading-out sheets and intercepting sheets in rechargeable battery packs).
The traditional production process of the nickel strap comprises the steps of slitting, vacuum melting, hot rolling, pickling, cold rolling, annealing and the like. The smelting step in the process inevitably brings impurities, so that the purity of nickel is greatly reduced, the loss of raw materials is large, particularly, the steps of smelting, casting, hot rolling, acid washing and the like in the traditional process are links with high energy consumption and high pollution, and new requirements are provided for the production process of the nickel strip in the face of the pressure from the energy environment.
Disclosure of Invention
The invention aims to provide a short-process rolling method of a nickel strip, and aims to solve the problems of long period, high energy consumption, complex process links and low purity of the nickel strip in the traditional nickel strip production.
The invention is realized in such a way that a short-process rolling method of a nickel strip comprises the following steps:
(1) rolling a high-purity electrodeposited nickel plate with the surface polished to be smooth by a two-roll roughing mill at a fixed rolling speed at room temperature at a reduction rate of 5-10% to obtain a primary rolled nickel strip with the thickness of 1 mm;
(2) and (3) carrying out multi-pass reciprocating rolling on the primary rolled nickel strip at room temperature by using a four-roll finishing mill at a fixed rolling speed, wherein the single pressing amount in the four-roll rolling process is 20-30%, so as to obtain the nickel strip with the thickness of 0.2-0.5 mm.
Preferably, in step (1), the electrodeposited nickel plate has a purity of greater than 99.9% and a thickness of 10 mm.
Preferably, in the step (1), the rolling speed of the two-roller roughing mill is 10-15 m/min.
Preferably, in the step (2), the rolling speed of the four-high finishing mill is 2-5 m/s.
The invention overcomes the defects of the prior art and provides the energy-saving, environment-friendly and efficient short-process rolling method for the nickel strip. The method not only saves the hot processing process which is necessary in the traditional production, but also reduces the related equipment and the working area; and avoids the requirement of adding other elements in the smelting process so as to reduce the purity of the nickel plate, thereby ensuring the higher purity of the nickel strip; in addition, the invention has the most characteristic that the starting sheet is not stripped, the electro-deposition nickel plate is directly rolled into the nickel strap, and the direct forming is completely carried out without any annealing treatment process during the multi-pass cold rolling, thereby effectively ensuring the forming precision of the nickel strap and improving the comprehensive mechanical property; in addition, the short-flow direct rolling of the electrodeposition material has the obvious advantages of reducing the loss of the nickel in the hot working process, reducing the production cost greatly, shortening the forming period and the like, greatly saving energy and reducing energy consumption.
Compared with the defects and shortcomings of the prior art, the invention has the following beneficial effects:
(1) the invention abandons the process link of casting the electrolytic nickel plate into the nickel ingot through vacuum melting in the traditional nickel strap foil manufacturing process, and realizes the direct room temperature rolling of the electro-deposition nickel plate;
(2) the invention greatly shortens the necessary working procedures of nickel strip production by short-process room temperature rolling, reduces the production period and greatly improves the production efficiency;
(3) the process flow of the invention cancels the links of smelting and casting, simultaneously reduces the links of chemical treatment such as acid washing, saves energy, reduces emission, reduces environmental pollution, has various current situations with high energy consumption, saves energy and protects environment;
(4) the technological process of the invention cancels the technological links of hot forging cogging and hot rolling, does not need the investment of hot rolling mill equipment, has various current situations of high energy consumption, saves energy and protects environment;
(5) the method can obtain the nickel strap with high purity and low internal resistance which reaches the industrial standard;
(6) the method simplifies the process flow, reduces the equipment investment, reduces the labor cost, reduces the necessary capital investment in the early stage in many aspects, greatly reduces the production cost and greatly shortens the production period;
(7) compared with the traditional process, the method of the invention has safer production flows.

(3) and (3) carrying out multi-pass reciprocating rolling on the primary rolled nickel strip at room temperature by using a four-roll finishing mill at a rolling speed of 5m/s, wherein the single pressing amount in the four-roll rolling process is 30%, so as to obtain the nickel strip with the thickness of 0.4 mm.
