Suitability of Auger Pressing Briquettes for Blast Furnace Use Based on Laboratory Tests

چکیده
Briquetting is a process in which fine materials unsuitable for use as such are agglomerated to achieve larger particle size. Auger pressing novel briquetting method efficiently improve the recycling of by-products from iron and steelmaking. The high-temperature properties auger briquettes mainly consisting blast furnace sludge mill scale were evaluated. aim was determine suitability (BF) ironmaking by studying reduction, swelling, cracking behavior using laboratory-scale furnace. simulator (BFS) capable performing non-isothermal reduction experiments with changing gas compositions used simulate different stages up 1100 °C an atmosphere N2, CO, CO2 gases. A commercial olivine pellet conventional industrial BF briquette reference samples. sample weight losses monitored thermogravimetry, swelling change volume, visual inspection. samples analyzed microscopes elemental analyzer. Based on BFS experiments, proved be promising raw material use. They self-reducing quality due their carbon content showed metallic faster compared slight, despite minor structure did not degrade.

The method of integrating many partial simulators for a complicated system in the consideration of interaction is proposed. Java Native Interface is used to integrate the simulators programmed in different languages. Remote Method Invocation is used to integrate the simulators in different computer environment. By applying the method to the partial simulators on the blast furnace, java-based in...
