Method for controlling surface lines of high-end beverage cans

Abstract

The invention provides a method for controlling surface lines of a high-end beverage can. The method comprises the following steps that a tin plate is poured into a double-rack temper mill to perform leveling operation, wherein the working parameters are set as follows: according to roller configuration of working rollers of the temper mill,an electric spark texturing roller is adopted as the 1# rack temper working roller with the roughness Ra controlled to be 1.45 + / -0.05 mu m, and a grinding smooth roller is adopted as the 2# rack temper working roller with the roughness Ra controlled to be 0.45 + / -0.04; temper mill temper roller grinding is carried out, wherein a grinding wheel with the particle size of 100-125 meshes is adopted, white sapphire or cubic boron nitride is adopted as the grinding material of the grinding wheel, and the hardness of the grinding wheel is selected as the middle grade 2; and the rolling force is controlled as follows: the rolling force of a 1# rack temper mill is 5500 + / -500KN, and the rolling kilometers are less than or equal to 300KM; and the rolling force of a 2# rack temper mill is 4000 + / -500KN, and the rolling kilometers are less than or equal to 200KM. By designing the unique working roller matching scheme of the temper mill, the grinding requirement of the temper rollers and the rolling process are effectively combined, and the current situations that the surface lines of the high-end beverage cans are rough, and the rolling lines of the plate face are not uniform can be fundamentally solved.

Description

technical field [0001] The invention belongs to the technical field of steel rolling, and particularly relates to a method for controlling the surface texture of a high-end beverage can. Background technique [0002] Tinplate is a cold-rolled low carbon steel sheet or steel strip plated with commercial pure tin on both sides. It has the strength and formability of steel, as well as the corrosion resistance, solderability and beautiful appearance of tin. It is suitable for packaging purposes. ideal material. The surface of tinplate is generally divided into eight forms such as B, R1, R, R2, S1, S, M, S2, among which B, R1, R and other types are the most common. These forms of surface are mostly used in the food can industry. In great demand. [0003] High-grade beverage cans are coated with transparent primer during the printing and coating process. After the printing is completed, the surface texture of the tinplate can be clearly enlarged. Therefore, the fineness and unif...
