Abstract
Material Frangible adalah material yang memiliki kemampuan untuk terdeformasi menjadi fragment fragment kecil ketika menerima beban tertentu. Material frangible telah dikembangkan sebagai material projektil peluru dengan penggunaan komposit matriks logam Cu-Sn sebagai material pada proyektil peluru frangible yang diproduksi melalui metode metalurgi serbuk mulai dari tahapan mixing, kompaksi, dan sintering. Sintering merupakan proses pembentukan ikatan antar partikel serbuk, sehingga akan menentukan sifat mekanik dari material frangible tersebut. Alat yang digunakan pada proses sintering material frangible adalah batch furnace laboratorium yang terbatas pada jumlah dan laju produksi material tersebut. Sementara untuk masuk pada industri pertahanan dibutuhkan material dengan jumlah yang tidak sedikit. Sehingga dibutuhkan continuous furnace dengan laju produksi yang lebih tinggi dibanding dengan batch furnace. Dari aspek temperatur operasi, temperatur pada continuous furnace harus disesuaikan kembali untuk mencapai temperatur material yang sama pada saat batch furnace. Dengan analisa termal yang dilakukan diperoleh temperatur operasi pada zona pre sinter adalah 250oC dan zona sinter sebesar 300oC. Kemudian dengan perancangan yang telah dibuat, diperoleh laju produksi furnace sebesar 812 butir per jam. Selanjutnya dengan perhitungan energi balance dan desain
komponen furnace, diperoleh total daya yang dibutuhkan continuous furnace sintering adalah sebesar 205.93395 kW

Frangible materials are materials that have ability to be deformed into small fragments when they received certain load. Currently frangible material have been developed as a bullet projectile material and used Cu-Sn metal matrix composite as material on frangible bullet projectiles. The Cu-Sn composite is produced through a powder metallurgy method that consisting of mixing, compaction, and sintering steps. Sintering step is an important process in the formation of bonds between powder particles, so it is enough to find the mechanical properties of the frangible material. The tool used in the process of sintering the frangible material is a batch furnace in a laboratory that is limited to the amount and rate of production of the material. In the process of sintering, the tools that used to sinter material is batch furnace which is limited in amount and rate of production frangible materials. Meanwhile, military industry required a lot of frangible material as a projectile. So continuous furnace is more reliable than batch furnace because of the rate production. Then in terms of operating temperature, the temperature at the continuous furnace must be adjusted again to meet the same temperature in batch furnace. By the thermal analysis, the operating temperature in pre sinter zone is 250oC and 300oC for sinter zone. And then, with the design that has been made, obtained the production rate of furnace of 812 bullet per hours. Furthermore, by calculating the energy balance and
furnace’s components, the total power required for continuous furnace sintering is 205.93395 kW.
