What is HBI?

Hot Briquetted Iron (HBI) is a product produced by the hot sponge iron briquetting (HDRI) process at temperatures above 650 ° C. This type of briquette is the best-known product worldwide for easy and safe transportation of sponge iron.

The iron and steel industry is one of the industries that utilize briquetting technology, such as coal briquetting, coke briquetting, and sponge iron briquetting, widely.

Sponge Iron briquette is a product used in many steel plants worldwide. The briquetting process, depending on the temperature of the sponge iron input to the briquetting machine, is divided into two groups: hot and cold briquetting.

HBI Specifications:

Among the hot briquetting properties of sponge iron that facilitate its transportation can be attributed to its low specific surface area, high mechanical strength and density, and optimum oxidation resistance.

HBI blocks the pores of DRI, decreases the accessible level, increases the density and upgrades thermal conductivity. All of these result in lowering the reactivity. Therefore, it is unexpected for HBI to be overheating. This feature results in easier and safer handling, storage and transportation compared to DRI.

 

Advantages of using HBI in EAF:

  • Low level of residual element values
  • certified and harmonious chemistry
  • homogeneous shape and form
  • High density
  • It can be continuously charged to the furnace
  • Acts as a Nitrogen scavenger.
