The iron and steel industry is one of the important basic industries in China, which produces a large number of iron and steel products every year, and also produces a large number of slag from steel mills. If not treated, the accumulation of slag will pose a threat to the environment. However, there are other uses of slag in steel mills, which can recover resources and reduce environmental pollution. The following is a full analysis of the use of slag in steel mills.

1. steel mill slag to make gift boxes

steel mill slag surface is smooth, bright color, can be made into a unique gift box, walk into a large shopping mall to observe the booth selling steel slag gift boxes, can be said to be a high-value recovery in the steel industry, adding color to people's lives.

2. steel plant slag to do building materials

steel plant slag in the composition is alkaline, can be added gypsum, lime and other materials fired together to make a new type of cement raw materials, used as building materials, this new type of building materials not only reduces the waste of resources, but also has good strength and firmness, good market sales.

3. steel plant slag to do calcium fertilizer

steel plant slag contains a certain amount of iron, phosphorus, potassium, nitrogen and other nutrients, can be used to make a new type of calcium fertilizer by microbial fermentation, to provide nutrients needed for plant growth, improve plant quality and yield.

4. steel mill slag as roadbed filler

steel mill slag can be ground into a fine powder, used to strengthen the bearing capacity of highway and railway roadbed, you know this use can not only create enough bonding force, crack resistance, durability is also very strong.

5. steel plant slag to do green tree pond

steel plant slag to add fertilizer and soil mixed to become a new type of planting material, can be used to make green tree pond, beautiful and generous, more conducive to plant fertilization and growth.

To sum up, although the steel plant slag has the problem of environmental pollution, through new technologies and new uses, the steel plant slag can maximize the recovery of resources, reduce pollution, and achieve the dual goals of resource conservation and environmental protection.
