New steel slag polymerization spray paint or new breakthrough

A few days ago, Baosteel Steel Slag Research Institute was informed that Baosteel's steel slag research continued to advance in depth, and recently there were "Experimental Research on Pretreatment of Converter Steel Slag Pressurized Steam," "Research on Metallurgical Non-iron Dust Prepared Lightweight Blocks," and "Slag Tank for Metallurgical Use". New steel slag polymerization spray coating research" Three major steel slag processing technology to achieve a major breakthrough, and achieved good results in practical applications. Relevant experts believe that these technologies have positive significance for the improvement of the environment and have broad application prospects.

In recent years, Baosteel Steel Slag Research Institute aims to enhance steel slag processing technology, develop green utilization industry and turn waste into treasure, and actively organizes MCC Baosteel technology and other units to carry out steel slag processing technology research. According to the characteristics of Baosteel's converter steel slag, China Metallurgical Baosteel Technology carried out the "Experimental Study on Pretreatment of Converter Steel Slag Pressurized Steam." Through the application research of industry, academia, and research institutes, it has effectively solved the key technical problems of low-energy treatment, stable and safe use of steel slag, and provided technical support for opening up new ways for the high value-added use of steel slag.

In order to cooperate with Baosteel’s Zhanjiang steel project, the non-ferrous dust and mud generated from its production will be turned into waste. The Steel Slag Research Association will cooperate with MCC Baosteel Technology and Shanghai University to carry out the “Metallurgical Non-iron Dust Preparation Lightweight Masonry Block Study. Through actual application tests, with the increase in the amount of iron-free mud-free incorporation, the compressive strength and dry density of foamed concrete meet the requirements of the standard. This product has been tested in building lightweight blocks. The project development will effectively promote the development and application of industrial solid waste in the field of new energy-saving wall engineering materials.

Slag cans are the key equipment containers for the processing of steelmaking slag to steel slag. The current slag tank protective agent is a slurry and sprayed to the protective layer on the inner wall of the slag tank. It can neither completely eliminate the slag problem of the slag tank, ensure the service life of the slag tank, or affect the slag intake requirements of the slag continuous drum treatment.

For this reason, China Metallurgical Baosteel Technology developed and developed a gunning product for the inner wall of a hot slag tank based on the principle of “similar compatibility” for Baosteel’s actual steelmaking plant. After the application of this project product, it can replace the lime and clay protection agent in the original process, and the effect is obviously better than the limestone and clay protection agent. The results of the tracking of the casting residue dregs show that 90% of the slag cans can be turned over directly, and 10% of the slag cans only need to be tapped, and there is no serious sticking phenomenon. The cast residue slag cans are more effective than the electric furnace slag slag cans. obvious.

The successful research and development of the three steel slag treatment technologies reflects the concept of “recycling wastes, wastes, and wastes” as a renewable resource. It can be used in major steel plants to promote the production of a virtuous circle and improve the efficiency of steel slag treatment. Production cost control. In addition, the "Experimental Study on Pressure Steam Pretreatment of Converter Steel Slag" and "Study on Metallurgical Non-iron Dust Preparation of Lightweight Blocks" were selected for the Baoshan District Science and Technology Commission Development Project and Baoshan District Science and Technology Commission's Production, Research and Development Project.
