Abstract
Kebutuhan baja nasional terus meningkat seiring berjalannya waktu. Tetapi berdasarkan data yang dipaparkan IISIA (Indonesian Iron and Steel Industry Association) Indonesia belum bisa memenuhi kebutuhannya sampai tahun 2020. Di tahun 2013 pun 66% pasokan baja nasional diimpor dari luar negeri. Hal ini kontras sekali melihat ketersediaan cadangan besi Indonesia yang sangat melimpah sekitar 140 juta ton.
Tidak hanya untuk sekedar memenuhi kebutuhan baja nasional, diperlukan juga teknologi yang berbasis eco-energy (energi terbarukan).. Dimana dalam penelitian ini, digunakanlah charcoal sebagai reduktor pembuatan Direct Reduction Iron.
Pada penelitian ini akan membahas pengaruh penambahan variasi jenis arang pada briket pasir besi terhadap kandungan Fe total dan derajat metalisasi pada proses pembuatan sponge iron. Briket ini akan direduksi dengan cara dipanaskan menggunakan muffle furnace sampai pada Temperature 13500C selama 3 jam lalu dilakuan holding pada temperature 13500C selama 10 jam, lalu dilakukan cooling 12 jam di dalam muffle furnace. Lalu hasil proses ini dikenai pengujian karakterisasi menggunakan pengujian EDX, XRD dan derajat metalisasi.
Dari hasil penelitian terlihat bahwa briket dengan reduksi maksimal ialah briket C dengan reduktor arang kayu alaban dengan pengotor yang paling sedikit, kadar Fe total 64, 145% derajat metalisasi 88,54%. Hal ini dikarenakan arang kayu laban memiliki kandungan Volatile matter yang tinggi sehingga kemampuan memproduksi gas CO lebih banyak untuk mereduksi besi oksida. =================================================================
National demand for steel continues to increase over time. But based on the data presented IISIA (Indonesian Iron and Steel Industry Association) Indonesia has not been able to meet his needs until the year 2020. In the year 2013 was 66% of national steel supply is imported from abroad. This is in contrast to see the availability of iron reserves are highly abundant Indonesia around 140 million tonnes.
Not just to meet the national demand for steel, also required a technology based on eco-energy (renewable energy) .. Where in this study, is used charcoal as a reductant manufacture of Direct Reduction Iron.
This research will discuss the effect of variations in the type of charcoal briquette iron sands on the total Fe content and the degree of metallization in the production of sponge iron. These briquettes will be reduced by heating using a muffle furnace until the Temperature 13500C for 3 hours and then was done holding at temperature 13500C for 10 hours, then cooling is done 12 hours in muffle furnace. Then the results of this process is subjected to the test characterization using EDX testing, XRD and degree of metallization.
From the findings, it seemed that the briquettes with a maximum reduction of C with a reducing agent is briquette charcoal alaban with the fewest impurities, total Fe content of 64,145% degree of metallization 88.54%. This is because the charcoal Laban had Volatile matter content is high, so the ability to produce more CO gas to reduce iron oxide.
