Cold-solidified briquetting is the main method for steelmaking sludge treatment in metallurgical enterprises at present.

The hydraulic protection device of the cold briquette roller press is that the hydraulic pump pumps high-pressure oil into the hydraulic cylinder to make the piston move axially. The front joint head of the piston rod of the carbon powder ball press meets the production pressure requirements on the bearing seat.

In order to make the large and medium-sized reduction electric furnaces of ferroalloy run better, it is required that the burden has proper fragmentation and ensures good air permeability. At present, the supply of high-quality lump burden which can be directly fed into the furnace is becoming increasingly tight. In order to adapt to this situation, some manufacturers at home and abroad have adopted various lump technologies to effectively utilize fine ore and concentrate and obtained better smelting indexes.

According to comprehensive analysis, LT dust can be reused while reducing environmental pollution by returning to converter for smelting after being lumped nearby, which is the best choice for its utilization mode.

Dust removal methods in the converter steelmaking process can be divided into the wet method and dry method. The traditional wet purification system is as follows: after the flue gas is treated by water spraying, the smoke dust is removed, and the sewage with smoke dust is treated by separation, concentration, and dehydration to obtain converter sludge, and the purified gas is recycled.

Industrial solid waste not only pollutes the environment but also causes huge waste of resources, which is one of the important issues concerned by the comprehensive utilization of resources and environmental protection in the world. Therefore, large enterprises finally explore recycling technology through the successful application of cold briquette technology in solid waste recycling.
