Brass rod material H59-1, H62, H65, H68, etc., brass rod production is generally divided into continuous casting rod, extrusion rod and continuous casting drawing rod, continuous casting rod production, first of all, after the copper raw materials melted into copper water, poured into the holding furnace, and then from the cleaner inside the hauling out, fixed-size cut off, hauling out of the surface of the copper rod has an oxidized layer, with the straight pulling machine to the surface of the black layer of pulling off the continuous casting of the production process of rods It is very simple, hairy rod pick a skin on the good, if sizing straightening and polishing is also possible, the surface can be done, the same as the extruded rod, only to do the crystalline phase in order to distinguish it, the extrusion of the rod of the process is relatively complex, the price is higher than the continuous casting of rods.
Continuous casting copper rod, as an important material in the field of metal processing, its production process, performance characteristics and application areas are extremely wide. This article will be from the production principle of continuous casting of copper rods, process characteristics, performance advantages, application areas, as well as with other production processes (such as extrusion of copper rods), such as the comparison, for the readers to fully analyze this material.
The production principle of continuous casting copper rods is relatively intuitive, but the process is quite delicate. Liquid copper is injected into the casting bath of a continuous casting machine at high temperatures. This process requires extremely high temperature control and purity of the liquid copper to ensure the quality of the final product. The design of the casting bath allows the liquid copper to be distributed evenly and, by increasing the cooling rate, to solidify quickly to form square or hexagonal rods. Once this step is completed, the copper rods undergo subsequent treatments such as drawing and stretching to be processed into various sizes of copper products. Continuous casting copper bar production process is relatively simple, high production efficiency, can quickly meet the needs of mass production.
In terms of process characteristics, continuous casting copper bar shows its unique advantages. Because it is made of continuous casting, its crystallization fineness is high, the crystallization direction is random, which makes the continuous casting copper bar has high strength and conductivity. This unique crystallization structure makes continuous casting copper rods have a wide range of applications in electric power, electronics, communications and other fields. In addition, continuous casting copper rods are internally homogeneous in particles, with high density and excellent performance in tensile strength, ductility and electrical conductivity. Internal purity without impurities, minimal porosity, stable physical properties, these are the important reasons why continuous casting copper rod can be widely used.
In terms of performance advantages, continuous casting copper rod is unique. Its high strength and excellent electrical conductivity, making it the ideal material for manufacturing wires, cables, motors and other power equipment. In the power industry, the stability of continuous casting copper rod can ensure the long-term stable operation of power equipment, reducing the equipment failure and maintenance costs caused by material problems. In addition, the ductility and malleability of continuous casting copper rods provide more possibilities for their use in manufacturing. Whether drawn into filaments or forged into sheets, continuous cast copper rods demonstrate excellent processability.
However, continuous cast copper rods are not perfect. The irregularities and angles of the surface are difficult to work with, which somewhat limits its use in certain applications. In addition, continuous casting copper rod for casting state organization, casting process exists in the porosity, porosity, inclusions and other defects are difficult to avoid completely. Although these defects will not seriously affect its overall performance, but in some of the application scenarios with very high material requirements, it may become a safety hazard. Therefore, when selecting continuous cast copper rods, comprehensive consideration needs to be made according to specific application scenarios and needs.
In terms of application areas, the performance of continuous casting copper rods is also impressive. In addition to the power industry, continuous casting copper rods are also widely used in shipbuilding, chemical equipment, oil and gas extraction and other fields. In the field of shipbuilding, due to its high strength and good seawater corrosion resistance, continuous cast copper rods are widely used in the piping system and propellers and other key components of ships. In chemical equipment, continuous casting copper rods are able to resist the corrosion of various chemical media and ensure the normal operation of the equipment. In oil and gas extraction, continuous casting copper rods are used to manufacture pipelines and connectors, ensuring the stable transportation and safe production of oil and gas.
In addition, continuous casting copper rods have a wide range of applications in electronic components, semiconductor materials and other fields. With the continuous development of science and technology, electronic components and semiconductor materials have higher and higher requirements for materials. Continuous casting copper rod has become one of the indispensable materials in these fields due to its excellent conductivity and processing performance. In the manufacture of electronic components, continuous casting copper rods can be processed into various shapes and specifications of wires, connectors and other parts to meet the high demand for materials for electronic components. In the field of semiconductor materials, continuous casting copper rods are also used to manufacture various connecting wires and conductive layers, which provide a strong guarantee for the performance and stability of semiconductor devices.
