Raw material processing
Calcium silicon alloy, pure copper, etc. are the main raw materials of calcium silicon cored wire. Before production, raw materials need to be processed, such as screening, impurities, weighing and other steps to ensure that the quality of raw materials meets the requirements.
Alloy smelting
Calcium silica powder and pure copper are mixed in proportion and added to a furnace for high-temperature smelting. In this process, it is necessary to pay attention to controlling the furnace temperature and maintaining the proportion of elements in the alloy to ensure that the alloy quality meets the requirements.
extrusion forming
The molten alloy is extruded through a mold to obtain a copper core. In the extrusion forming process, it is necessary to pay attention to controlling the extrusion speed, temperature, mold pressure and other parameters to ensure that the quality of the copper core meets the requirements.
core wrapping
The copper core is wound with calcium silicate core-spun, and it is necessary to pay attention to parameters such as winding tightness and core diameter in this process to ensure that the quality of the core spun meets the requirements.
Insulation treatment
The copper core wound by the core is insulated to improve the insulation performance of the cable. In the process of insulation treatment, it is necessary to pay attention to the selection, thickness, strength and other parameters of the insulation material to ensure that the insulation performance meets the requirements.
Finished product inspection
Finally, the finished product inspection of the insulated calcium silicate cored wire includes multiple indicators such as appearance quality, electrical properties, and insulation properties. Only products that have passed the inspection can be sold out of the factory.
The above is the production process of calcium silica cored wire, which fully considers the quality control and technical requirements of each link to ensure the stability and reliability of product quality and performance.
