Abstract

The invention relates to a cold-rolled hot-dip galvanized steel sheet for an easy-open lid pull ring and a production method thereof, which mainly solves the low tensile strength and high production cost of the existing cold-roll hot-dip galvanized steel sheet for an easy-open lid pull ring question. A cold-rolled hot-dip galvanized steel sheet for an easy-open lid pull ring provided by the invention, the mass percentage of its chemical composition is: C: 0.025%-0.04%, Si: 0.005%-0.03%, Mn: 0.26%-0.35% , P≤0.015%, S≤0.013%, Alt: 0.03%~0.07%, B: 0.004%~0.005%, the balance is iron and unavoidable inclusions. The invention is mainly used for making the pull ring of the easy-open end.

Description

technical field [0001] The invention belongs to the technical field of iron-based alloys, and relates to a cold-rolled hot-dip galvanized steel sheet, in particular to a cold-rolled hot-dip galvanized steel sheet for an easy-open lid pull ring and a production method thereof. Background technique [0002] Metal packaging materials have outstanding features such as good surface decoration, high strength, and convenient storage and transportation, and are increasingly popular among people. Metal cans were originally used to package food, and metal two-piece and three-piece beverage cans have become one of the main packaging forms for carbonated beverages, fruit juices, beer, etc. At present, although there are many specifications and models of popular beverage cans on the market, most of the can lids are pull-ring type easy-open lids. The basic requirement for an easy open end tab is that it must have high strength in order to pull the seal of the metal can smoothly. The exi...
