practice of green metallurgy

Green metallurgy is a concept that has attracted much attention in recent years. It emphasizes the root cause of pollution in the production process, and is committed to eliminating pollutants in the production process rather than afterwards, coordinating economic and environmental benefits, and pursuing sustainable Adopt preventive strategies for environmental pollution to constitute the best model of sustainable development.



Green metallurgy and pure metallurgy pollution control are different concepts, and even have different positions. The position of pollution control is often to treat the environment that has been polluted and restore it to its pre-polluted appearance. This method often leads to an increase in the cost of the company and even weakens the company’s market competitiveness; green manufacturing emphasizes the source New strategies to prevent the generation of pollutants. We must attach great importance to green manufacturing, start with process science, technology and engineering research and development, develop environmentally friendly production processes, technical equipment, and manufacturing processes to resolve the contradiction between environmental pollution and sustainable development.

The concept of green metallurgy, that is, metallurgical production with environmental protection awareness, is a modern metallurgical material manufacturing mode that comprehensively considers the impact of the ecological environment, resources, and energy consumption. Its goal is to make metallurgical products from design, development, production, preparation, and processing By entering the entire product life cycle of material use, the negative impact on the environment is minimized, and the use efficiency of resources and energy is maximized. For example, there is a raw material for metal silicon in steel smelting. Silicon is often used as a deoxidizer. Silicon Slag was originally a solid waste from the production process of silicon metal. Some ferroalloy companies, such as Anyang Huatuo Metallurgy, and some steel plants, make Silicon Briquette through the processing of Silicon Slag, which makes Silicon Metal Scrap, which might otherwise pollute the ecological environment, become Silicon Metal Briquette that can be used for deoxidation. , This is a kind of recycling. It not only protects the environment, but also reduces costs and improves efficiency.

In the metallurgical process, the fundamental cause of environmental pollution in the metallurgical system of material preparation is the consumption of resources and energy, as well as the generation and discharge of waste. Therefore, green metallurgy embodies the inseparable relationship between resources, energy and ecological environment. In this concept, the environment is a comprehensive concept that includes both the natural environment and the production and use environment of resource consumption, energy consumption, and waste. For steel companies, a good grasp of this concept is of far-reaching significance to their sustainable development.
