Bulk Bags in Steel Mills: Electric Arc Furnace Dust, Refractories, and Steel Additives Packaging

Steelmakers convert high-grade steel scrap into new prime steel using innovative, high-tech mini-mill technology. In the mini-mill process, high-grade steel scrap is combined with pig iron, hot briquetted iron (HBI), and other metals and melted at a temperature of approximately 3,000 degrees Fahrenheit in an electric-arc furnace (EAF). 

About one-quarter of the world’s steel is produced by the electric-arc method, which uses high-current electric arcs to melt steel scrap and convert it into liquid steel of a specified chemical composition and temperature. 

Mini-mills are more cost-effective and environmentally friendly than the traditional integrated steel mills.

 

EAF Dust

Electric-arc furnace dust (EAFD) is one of the several process residues generated in mini mills during steel production. The presence of valuable zinc in EAF dust and the rising costs for waste disposal are the motivating factors for EAFD recycling or its incorporation into other materials. 

Bulk Bags are often used to package EAF dust for recycling or disposal. Their strength, functionality, and the ability to withstand harsh environments make an FIBC the perfect packaging option for the steel and heavy metals industries. 

 

Monolithic Refractories

Refractories are those materials which withstand high temperature without a significant change in chemical or physical properties. Refractory materials are very important to the electric arc furnace (EAF) operation as they provide for the containment of liquid steel. The EAF needs a variety of refractory products out of which the most important are those refractory products which are in direct contact with the liquid steel. 

Graphite, carbon, and magnesia based monolithic refractory products are commonly packaged in multi-wall paper bags, poly bags, and FIBC bulk bags. Batch inclusion style poly bags are also used to package refractory ingredients used in the steelmaking process.  

 

Steel Additives

A range of additives including carbon, calcium silicon, and nickel are used in the steelmaking process. Many of these additives are packaged in heavy industrial bags including FIBCs and multi-wall paper bags.

Heavy metal additives such as nickel briquettes can be packed in bulk bags designed to hold up to 5,000lbs of material. Furthermore, FIBCs are a safe, cost effective way to transport heavy materials within a mill.
