Basic Situation Of Foundry Industry in China

According to the analysis and estimation of relevant data, there are more than 20000 foundry sites in China, and the number of employees is about.

More than 1.2 million people, with an annual output of about 12 million tons of castings. The output value of castings exceeds 40 billion yuan, ranking the second in the world. In 1994, about 550000 tons of castings were exported, with a total value of 330 million US dollars. From the perspective of industrial structure, there are a large number of foundry branches or workshops subordinate to the main engine manufacturers or companies; there are also a large number of independent professional foundries (mainly process specialization) developed in the process of implementing specialized production; there are also a large number of small-scale foundries established in townships and towns since the reform and opening up. In terms of scale and level, there are large-scale foundries with advanced technology, high degree of mechanization and an annual output of tens of thousands of tons of castings; There are also small foundries with backward technology, simple equipment and basically manual operation, with an annual output of 100 tons of castings. The labor productivity of the whole staff, taking iron castings as an example, the national average level is about 8-10 tons / person year. -- The energy consumption per ton of iron castings and steel castings in general foundry is 550-650 kg of standard coal and 900-1000 kg of standard coal respectively. In the past ten years, through technological transformation, a number of enterprises have made great progress and made changes, forming a number of backbone foundry production plants with advanced levels. However, in general, China's foundry industry still faces serious problems such as poor economic benefits, low casting quality, high energy and material consumption, poor labor conditions, and environmental pollution.
