This study explored the possibility of using upgraded coal and coke from Indonesian lignite in ironmaking process, specifically pulverized Injection (hereafter, “PCI”) carbon composite pellets material (sintering binder material). The found that (1) injection into blast furnace will have same effect as lime - heavy oil slurry furnace, combined infusion highly volatile matter low ash coal, flash...

Abstract. Technological knowledge of the use metals is inseparable from human in processing pyrotechnics fire as a power high temperature processes for producing objects. The used smelting and casting melting furnaces. Metal furnace heat production device, which to purify metal, this case iron. This paper aims determine development ferrous metal technology Indonesia with library research method...

Size measurement of iron ore pellets in industry is usually performed by manual sampling and sieving techniques. The manual sampling is performed infrequently and is inconsistent, invasive and time-consuming. Iron ore pellet’s sizes are critical to the efficiency of the blast furnace process in the production of steel. Overly coarse pellets affect the blast furnace process negatively, however t...

Concrete is a mixture of cement, fine aggregate, coarse aggregate and water. Concrete plays a vital role in the development of infrastructure Viz., buildings, industrial structures, bridges and highways etc. leading to utilization of large quantity of concrete. On the other side, cost of concrete is attributed to the cost of its ingredients which is scarce and expensive, this leading to usage o...

There has always been a dispute about the energy efficiency and energy cost of electro-driven and turbo-driven blast furnace (BF) blast processes. In order to find where the problem lies, energy efficiency analysis models and energy cost analysis models of electro-driven and turbo-driven blast processes were established, and the differences between the two driving processes in terms of theoreti...

A method for detecting and isolating incipient leakages in the valves of a pulverized coal injection vessel for a blast furnace process is presented. Nonlinear physical gray-box models of the plant are developed. Values of the unknown parameters are estimated by identification. Observers are constructed for these models and the residuals are used in a generalized likelihood ratio test. The meth...

This study presents an ex-ante life cycle assessment of a carbon capture and utilization technology that converts emissions from the blast furnace gas steel mill to valuable intermediates for production polyols.
