In the production of wire and cable, because of its raw material costs accounted for more than 80% of production costs, and copper, aluminum, steel core, rubber, plastic and sheath materials and other raw materials for the cost of raw materials, which requires wire and cable enterprises in how Design a unique product, save raw materials, the development of new environmentally friendly materials and other efforts. Therefore, the future must consider the following measures to build the wire and cable industry, recycling economy:
First, out of cold rolling mill and black copper rod. The production process of the black copper rod with the cold rolling mill is backward, and its black copper rod oxide content is high, the electrical conductivity is low, the performance is poor, the pulling weight is small, the consumable material, energy consumption and serious pollution should be Out of phase.
Second, actively promote the optimization of aluminum rare earth technology. With the continuous casting and rolling process to produce electrical aluminum rod in the country has been quite popular, the performance is also good, but the equipment is still in the early 1970s development level, the technology is not much innovation. To actively promote China's unique aluminum rare earth optimization technology. And the use of the introduction of some key special equipment and technology to add aluminum zirconium alloy, aluminum melting furnace into aluminum melting oil or natural gas furnace, all the elimination of molten aluminum furnace coal dust and flue gas emissions, and set the flue gas Filtration device to purify flue gas, improve the quality of emissions, improve the yield, reduce costs, while the wire working temperature from 70 ℃ to 150 ℃, carrying capacity increased 1.6 times.
Third, the active introduction of technology, independent innovation and development of excellent performance of wire and cable equipment. At present, the leading production line of wire and cable products and foreign advanced equipment, the technical level gap is still large, mainly in the low productivity, low degree of automation, energy consumption, reliability is poor, can not meet the development of the industry Need, digestion and absorption serious lag. The technical level, performance and reliability of wire and cable equipment are of immeasurable benefits for improving the quality of wire and cable products, production efficiency and material utilization. To actively introduce technology, independent innovation and development of excellent performance, high level of wire and cable equipment, wire and cable industry to create a circular economy services. Finally, the active development of environmentally friendly wire and cable products, to strengthen the recycling of waste wire and cable products. At present, the production of wire and cable products, extensive use of rubber, polyvinyl chloride, polyethylene and other polymer chemical materials. In the production of wire and cable products in the process of producing a large number of toxic and harmful gases. Therefore, we should actively develop environmentally friendly wire and cable raw materials, production products, environmentally friendly wire and cable. Japan Fujikura and other cable companies in the development of environmentally friendly wire and cable products, in order to monopolize the market, and actively promote the government promulgated environmentally friendly wire and cable product standards. In recent years, environmentally friendly wire and cable products, the rapid increase in sales share, ordinary wire and cable and flame retardant wire and cable can not compete with it. In the production process of wire and cable produced in the corner of the remaining material, can be directly recycled. Proposed the establishment of a professional "PVC" waste recycling plant, sentinel processing, changed for other use, to avoid secondary pollution.
