Abstract

The invention discloses a resurfacing welding used drug cored steel strap and the preparation method. The steel strap is prepared from a mild steel strap and drug powder enwrapped therein, the shape of the steel strap is a tube with the longitudinal cross-section to be in a long and flat shape or in a similar rectangle shape, the longitudinal length can be determined randomly, and the transverse sides of the steel strap are connected in a seam manner or a related joint manner; the drug powder is uniformly filled in the tube rolled from the steel strap, wherein the particle diameter of the drug powder is smaller than 120 Mum, the components include (by weight) 45-70 parts of high carbon ferrochrome, 5-35 parts of ferrovanadium, 1-8 parts of No.75 ferrosilicon, 1-10 parts of high carbon ferromanganese, 2-16 parts of ferroboron, 1-8 parts of ferrotitanium, 0-5 parts of ferroniobium, 2-8 parts of ferromolybdenum, 0-10 parts of graphite, 0-5 parts of fluorite and 0-6 parts of potassium titanate. The drug cored steel strap adopting the invention can efficiently improve the abrasion resistance of the metal on the resurfacing welding layer and the stability of the electric arc, and can becoiled into coils, thereby being suitable for continuous automatic resurfacing welding.

Description

technical field

[0001] The invention relates to a welding material, in particular to a surfacing flux-cored steel strip 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 used because of its simple proces...
