China's foundry industry should adopt the development model of circular economy

- Jul 21, 2018-

Adopting the development model of circular economy and establishing a resource-saving and environment-friendly foundry industry is an important way to reduce energy consumption. Various industrial furnaces and kiln in the casting production process are large consumers who consume resources and are also the source of polluting environment. Making full use of the residual heat of the kiln in the casting production process can reduce energy consumption. For example, a factory in Shandong introduced the residual heat of the cupola into the drying room to dry the painted parts, which achieved energy saving. Use the residual heat of the cupola to heat domestic water. According to the Germans, garbage is the wrong place. Waste reduction, reuse, recycling, and remanufacturing in foundry production should be given full attention. According to the introduction, the cost of dumping one ton of waste sand is higher than the cost of purchasing new sand, and the indexes of recycled sand are no less than that of new sand. According to the current domestic new sand price and the cost of reclaimed sand, the regeneration cost is only one-third of the new sand. A large amount of slag can be used as a raw material for the production of cement as a good method to reduce pollutant emissions.

For more than 20 years, the development of China's foundry industry has mainly relied on the use of cheap labor and domestic resources, energy, and even excessive investment. With the rapid development of China's economy and the continuous expansion of its scale, the constraints of domestic energy, resources and ecological environment on economic growth are increasing day by day. The development of the foundry industry is also facing a series of major challenges. If you follow the path of extensive, high growth, at the expense of resources and the environment, it will definitely not go. China has been ranked as the world's largest casting production country for six consecutive years. However, from the perspective of the increasing energy constraints faced by China's foundry industry, the increasing pressure on environmental safety, the intensification of competition in the international foundry industry and the strengthening of intellectual property protection, China's foundry must be transformed from a big country to a strong country, reducing energy consumption within five years. 20%, reducing pollutant emissions by 10%, only by innovation and improving the quality of employees, relying on the establishment of a harmonious manufacturing philosophy, relying on the development of circular economy can have hope.
