The raw material of calcium silicon cored wire is silicon calcium powder, and the specific production method is to use silicon calcium powder as the core material, with steel skin as the outer skin, and then through the line pressing machine to make. In addition, when making cored wire, we should pay attention to whether the steel skin is tightly covered and whether there is any leakage of material. During the production, we should strictly check the problem of each ring.
Calcium silicon cored wire is widely used in daily life, but there are also many problems in the process of use, which will affect the normal use of the product. In order to effectively ensure the normal use of the product, we should understand the following common problems and solutions.
1. The product is compressed or pulled.
In addition to the hollow material of the core wire, the leakage material of the core wire is not tight and the core wire is not solid, there are also poor quality of the steel belt and the roller of the feeding machine is worn, etc., all of which will cause the core wire to be crushed or broken by the feeding machine, thus leading to the failure of the feeding wire. In this case, it is necessary to adjust the equipment, cutting speed and the particle size of silicon and calcium alloy, improve the quality of cored wire, and reflect the roller wear condition to the material unit in a timely manner.
2. Bulk material of cored wire.
In the case of bulk packing, we can weld the core coil and then add the packing tape.
