At present, with the increasing shortage of global ore slag resources and the urgent need for environmental management, all countries in the world have focused on improving the utilization rate of renewable resources by establishing a recycling-oriented society that reduces environmental pollution. For example, common steel slag, steel slag is a by-product of steelmaking production process, and it is a good second resource. Reasonable and effective use of steel slag will have unexpected gains.

The way iron and steel mills used to control scrap was mainly to extract 10% of scrap steel, while 90% of tailings were discarded, wasting resources and polluting the environment. Nowadays, the development and utilization of steel slag is relatively mature. The steel slag is ground into steel slag powder through a series of equipment of steel slag micro-powder production line, and mixed with slag powder to produce steel slag powder for cement and concrete production.

The steel slag micro-powder after grinding by the slag vertical roller mill can be used as a raw material in the building materials industry, which not only can save resources, reduce waste, improve the environment, but also can create the best industrial chain combination and realize the harmonious development of the industrial industry.

Use of steel slag powder

First, steel slag powder can be used in concrete production. Steel slag composite powder (fly ash, slag powder, steel slag powder) can be used to replace 20%-50% ordinary Portland cement, which can produce C20～C60 different strength grade concrete with excellent performance.

Secondly, steel slag powder can be made into Portland slag in a certain proportion, which can be made into steel slag Portland cement, low heat steel slag cement, steel slag road cement, steel slag masonry cement, etc.; it is mixed with 30%~40% cement clinker. A large proportion of steel slag composite powder can prepare P·C32.5 grade green composite cement.

Thirdly, the steel slag-based expansion agent can be developed to prepare medium and low-grade large-volume concrete. The maximum temperature rise of the insulation can be controlled below 500 °C, and the impermeability level reaches above P40, which can inhibit the formation of delayed ettringite in mass concrete. Controls concrete cracking caused by temperature rise.

Construction of industrial waste residue production line, chaeng has a wealth of construction plans and successful cases, whether in the selection of the slag production line configuration or the later production standards, chaeng can make customers satisfied. The steel slag production line has been successfully unlocked and the steel slag resource recycling model has been successfully unlocked, which brings considerable economic and social benefits to the company!
