Scope

Scope: This standard specifies the requirements for air pollution emission control and monitoring in the foundry industry, the scope of application of terms and definitions, and the requirements for pollutant emission control and monitoring. This standard applies to existing standalone foundries and enterprises with foundry workshops in the following processes: metal melting, molding, core making, casting, sand removal, cooling, recycling of used sand, post-casting heat treatment, and surface coating, as well as the management of air pollutant emissions in foundry industrial construction projects, including environmental impact assessments, environmental protection facility design, completion environmental protection acceptance, and air pollutant emission management after operation. Main technical content: The air pollutant emission limits for foundry enterprises are divided into two levels; Level 1 applies to general areas, and Level 2 applies to key air pollution prevention and control areas. The emission concentration limits for production processes and equipment at each level are as follows: **Level 1** - Metal melting: Cupola furnace: 40, 100, 150 - Workshop or production facility exhaust stack: Electric arc furnace, refining furnace: 30-150 - Gas furnace: 20,50,200 - Other melting equipment: 20 - Molding, core making, casting, sand removal, cooling, sand recycling: Molding machines, core making machines, shot blasting machines, sand removal machines, grinding machines, sand recycling equipment, etc.: 20-50-80 **Level 2** - Metal melting: Cupola furnace: 20, 60, 100 - Gas furnace: 15,50,150 - Electric arc furnace, refining furnace: 15-150 - Other melting equipment: 15 - Molding, core making, casting, sand removal, cooling, sand recycling: Molding machines, core making machines, shot blasting machines, sand removal machines, grinding machines, sand recycling equipment, etc.: 15-50-60
