Abstract

The invention relates to a flux-cored welding wire, particularly to a high-wear-resistant alloy steel welding wire flux core. The high-wear-resistant alloy steel welding wire flux core is prepared from the following components in percentage by weight: 8-10% of high-carbon ferrochrome alloy powder, 1.5-2% of electrolytic manganese metal powder, 2.5-4% of ferroboron alloy powder, 2-4% of ferrocolumbium alloy powder, 2-4% of ferrosilicon alloy powder, 2-3% of ferromolybdenum alloy powder, 1-2% of aluminum powder and the balance of iron powder. Three types of wear-resistant-material strong carbide forming elements of chromium, molybdenum and columbium are added into the flux core, so that the formed cubic system carbide is high in hardness and good in thermostability, and the abrasive resistance of the weld alloy can be improved; a proper amount of aluminum is added, so that not only are the deoxidization and nitrogen fixation capacities improved, but also the electrical arc stability is further improved, the carbon oxidation is inhibited, and in addition, overflow splashing of gas is reduced.

Description

technical field [0001] The invention relates to a wear-resistant welding wire, specifically a high wear-resistant alloy steel welding wire flux core. Background technique [0002] In the actual industrial production process, the wear and tear failure of mechanical equipment and parts has a huge impact on production. Reducing wear plays an important role in saving energy and materials, making full use of resources and ensuring safety. The most effective way to reduce the wear of mechanical parts is welding. The emergence and development of flux-cored wire adapts to the trend of high-efficiency, low-cost, high-quality, and automated development of welding production. With the rapid development of world industry, welding technology has gradually entered the stage of semi-automatic, automatic and intelligent, so the development of drug-cored welding wire has brought broad prospects. Flux-cored welding wire is an advanced welding material that has developed rapidly and spread ...
