The environmental protection indicators of agricultural machinery forgings mainly include the following requirements: Material selection: When producing agricultural machinery forgings, environmentally friendly and pollution-free materials should be selected. For example, give priority to recyclable metal materials and avoid materials containing harmful substances. Energy saving and emission reduction: In the manufacturing process of agricultural machinery forgings, measures of energy saving and emission reduction should be taken. For example, reasonable design of forging process to reduce energy consumption; Optimize equipment operation to reduce energy waste; Establish and implement effective waste gas and liquid waste treatment measures to reduce pollutant emissions. Recycling: Agricultural machinery forgings should have the characteristics of recycling after the end of their service life. Through reasonable consideration in the design and manufacturing process, the reuse value of agricultural machinery forgings is improved as much as possible. For example, the use of removable assembly, easy to repair and replace parts; Consider the degradability of forgings to facilitate subsequent treatment. Waste treatment: The waste generated in the production process should be treated reasonably. For example, the separation of waste that can be recycled for reuse; For waste that cannot be recycled, environmentally friendly treatment methods should be adopted, such as safe landfill, incineration, etc. Environmental monitoring: Environmental monitoring and assessment of the production link of agricultural machinery forgings, timely discovery and solution of environmental problems. Establish a sound environmental management system to ensure environmental compliance in the manufacturing process of agricultural machinery forgings. It should be noted that the specific environmental protection index requirements may vary according to different national, regional or industry standards, and need to be referred to and complied with according to the specific situation.
