Abstract

The invention discloses a flux-cored steel-belt that contains steel wires and is used for surfacing and a preparation method thereof. The flux-cored steel-belt is produced from low-carbon steel belts and powder and a steel wire enwrapped therein. The shape of the steel belts is a tube, of which the vertical cross section is in a long flat shape or a rectangle-like shape and the horizontal sides are connected in a closing form or a lapping form. The powder is evenly filled in the tube rolled from the steel belts and the steel wire which is arranged vertically along the tube, has the same length with the tube and positioned at the geometric center of the vertical cross section of the flux-cored steel-belt is clamped in the middle of the powder. Through the adjustment of clamping the steel wire and the powder flux-cored steel-belt of the invention, the variety of steel belts used for surfacing is added, thus reducing cost. The flux-cored steel-belt can be wound into a disk-like shape, thus being suitable for continuous automatic surfacing, leading the application field of strip surfacing to expand, increasing the stability of electric arc and reducing the technical requirements against welding equipment.

Description

technical field

[0001] The invention relates to a welding material, in particular to a flux-cored steel strip containing steel wires for overlay welding and a preparation method thereof. Background technique

[0002] Most of the mechanical parts are made of metal materials, and wear will occur due to the relative movement between parts or between parts and materials. With the development of modern industry, mechanical parts often work under extremely complex and harsh conditions, and a large number of mechanical equipment are often scrapped due to wear and tear. This requires the surface of mechanical equipment under heavy loads and other working conditions to have good durability. grinding performance.

[0003] It is a common method to manufacture or repair wear-resistant parts at present to prepare a wear-resistant alloy layer on the metal surface by surfacing welding, thermal spraying, vapor deposition, electroplating and other technologies. Surfacing welding is widely ...
