Problems solved by technology

[0010] In view of the above situation, the object of the present invention is to provide a welding core for forging and rolling high manganese steel wire, which can be used as manual electric welding core, submerged arc welding core and other high manganese steel welding core, which can effectively solve the problem of ferromanganese welding. The problem of poor welding performance such as unevenness and poor weld quality, the technical solution is to use chemical components in terms of mass fraction: 1-1.3% C, 0.3-0.5% Si, 11-14% Mn, P ≤0.035%, S≤0.025%, and the balance is Fe high-manganese steel wire to make electric welding core. Used as manual electric welding core, submerged arc welding core or other high manganese steel core, its popularization and application is a great creative contribution to high manganese steel welding

Embodiment Construction

[0011] The specific implementation manners of the present invention will be described in detail below in combination with actual conditions.

[0012] The electric welding core of the present invention is made of forged high manganese steel wire as the electric welding core, and the chemical composition of the high manganese steel wire is 1-1.3% of C (carbon) content and 0.3-0.5% of Si (silicon) content in terms of mass fraction. , Mn (manganese) content 11-14%, P (phosphorus) content ≤ 0.035%, S (sulfur) content ≤ 0.025%, and the balance is Fe (iron). The material is realized by smelting, forging, rolling, It is made of forged rod by heat treatment and then drawn. After the wire is drawn, it is processed and drilled according to the routine to form an electric welding core for forging and rolling high manganese steel. Or use other smelting and manufacturing methods to make the material of the present invention and then make it into an electric welding core. % Si, 11-14% Mn, P...

Abstract

A forged and rolled the high-Mn core wire of electrode for electric welding contains C (1-1.3 mass %), Si (0.3-0.5 mass%), Mn (11-14 mass %), P (0-0.035 mass%), S (0-0.25 mass%) and Fe (rest). its advantages are uniform welding, and high quality and strength of welded seam.

Description

1. Technical field [0001] The invention relates to a welding rod core for welding, in particular to an electric welding core made of forged and rolled high manganese steel wire. 2. Background technology [0002] The welding performance of high manganese steel is not good, but its high strength, high toughness, high wear resistance and non-magnetic excellent performance make it used in many occasions. However, because high manganese steel hardens quickly and is difficult to cut, it is generally limited to castings. Although it has been used in welding at present, the application effect is not ideal due to the unreasonable composition of the material. The materials currently used for high manganese steel welding are as follows: [0003] Types of chemical composition (%) prepare Note C mn Ni Cr Mo V Si P S Mn-Ni 0.7-0.9 13-16 ...
