Abstract

A multi-layer cored wire is composed of an outer steel strip of an outer layer (1), heat insulating materials of the outer layer (2), an inner steel strip of the outer layer (3), metal powders of the outer layer (4), an outer steel strip of an inner layer (5), heat insulating materials of the inner layer (6), a inner steel strip of the inner layer (7) and metal powders of the inner layer (8). An inner steel band is formed by inserting the heat insulating materials of the inner layer between the outer steel strip of the inner layer and the inner steel strip of the inner layer, and then an inner cored wire is formed by filling the metal powders of the inner layer in the inner steel band. An outer steel band is formed by inserting the heat insulating materials of the outer layer between the outer steel strip of the outer layer and the inner steel strip of the outer layer, and then the multi-layer cored wire is formed by packaging the inner cored wire with the outer steel band and filling the metal powders of the outer layer between the outer steel band and the inner steel band. The multi-layer cored wire which has two layers of steel bands can reach the bottom of metal solution and make the metal powders be added into the metal solution uniformly.

Description

技术领域 Technical field

本实用新型涉及一种包芯线， 特别涉及一种新型多层包芯线中线。  The utility model relates to a core wire, in particular to a novel multilayer core wire center line.

背景技术 Background technique

自前， 多数包芯线生产厂商在生产包芯线时都是由单层钢带包裹金属粉的 结构制造， 其缺点在于当包芯线进入钢炉后， 由于钢水的高温包芯线未能到达 金属溶液底部就已经融化了， 这样会造成包芯线内要添加的金属粉多数都在金 属溶液的上层， 但金属溶液的下层却没有融化金属粉， 这样就会使金属粉添加 不均匀， 造成其性能不稳定或造成添加包芯线的'浪费等问题。  Since the beginning, most of the core wire manufacturers have manufactured a single-layer steel strip wrapped with metal powder in the production of the core wire. The disadvantage is that the high-temperature core wire of the molten steel cannot be reached after the core wire enters the steel furnace. The bottom of the metal solution has melted, which will cause most of the metal powder to be added in the core wire to be in the upper layer of the metal solution, but the lower layer of the metal solution does not melt the metal powder, which will cause the metal powder to be unevenly added, resulting in Its performance is unstable or causes problems such as waste of adding core wires.
