Problems solved by technology

However, the shortcoming of the bell furnace annealing process with a small reduction rate is that due to the need for more than ten hours of 700-degree high-temperature heat preservation annealing, it is easy to cause the precipitation of graphite carbon, which affects the comprehensive performance of the spring steel strip after quenching, making the spring The elastic tension of the steel belt is small, so this spring steel belt is easy to break and has a short service life.

Abstract

The invention relates to an elastic steel belt and a production method thereof. The elastic steel belt is characterized by being prepared from the raw materials such as waste steel, molybdenum, niobium, vanadium and the like by the steps of smelting, hot rolling, acid pickling, cold rolling and the like. The elastic steel belt is not broken easily, has long service life and is applicable to the production fields such as clocks, mechanical toys, household appliances, steel tapes, automobile safety belts and the like.

Description

technical field [0001] The invention relates to a steel strip and a production method thereof. Specifically, it is elastic steel belts and production methods thereof for the production of clocks, motor toys, household appliances and steel measuring tapes. Background technique [0002] It is known in the metallurgical industry that elastic steel belts are mainly used in the production fields of clocks, motor toys, household appliances, and steel tapes. Traditional elastic steel strips mainly include 60 silicon 2 manganese, 60 silicon 2 manganese A, 60 silicon 2 chromium A and 60 silicon 2 chromium vanadium A. The production process of the above four spring steel strips is: melting, pouring, hot rolling and cold rolling. rolled. The above-mentioned spring steel strips have the following defects. The steel strip crystal grains are easy to coarsen during hot rolling, and the brittleness tends to be serious during cold rolling, which makes it easy to crack and break. Cold rolli...
