Abstract

Pada industri baja, Electric Arc Furnace (EAF), Ladle Refining Furnace (LRF), Continuous Casting Machine (CCM) merupakan komponen penting dalam proses produksi baja. Air merupakan komponen penting dalam sistem pendinginan pada ketiga proses tersebut. Oleh karena itu, pompa sentrifugal yang digunakan untuk mendistribusikan air agar dapat berfungsi secara optimal agar dapat memberikan kinerja yang hemat energi.
Penelitian ini bertujuan untuk menghitung head efektif distribusi air, mengoptimalkan kondisi pompa di lokasi yang mengalami oversized dengan menghitung performa pompa sebelum dilakukan trimming impeller dan menghitung performa pompa setelah trimming impeller untuk mengatasi permasalahan besarnya penggunaan energi, dan mengeksplorasi dampak akibat trimming impeller terhadap kinerja pompa. Hasil dari Penelitian ini perhitungan head effektif yang dilakukan pada kelima sistem dengan melakukan penjumlahan secara cirucit complex maka diperoleh head 61,72m serta penggunaan dua pompa jumbo dengan trimming impeller sebesar 7,5% dan pengoperasian secara paralel, dikombinasikan dengan penyesuaian safety factor dan throttle katup, menunjukkan bahwa sistem dapat beroperasi dengan optimal dan dalam batasan yang aman. Trimming impeller sebesar 7,5% dapat menghemat energi sebesar 530 kWh atau dalam saving cost sebesar Rp. 28.627.510 per bulan

In the steel industry, the Electric Arc Furnace (EAF), Ladle Refining Furnace (LRF), and Continuous Casting Machine (CCM) are crucial components in the steel production process. Water serves as a vital cooling component in these three processes. Therefore, centrifugal pumps are used to distribute water efficiently to ensure energy-efficient performance.
This research aims to calculate the effective head for water distribution, optimize pump conditions in oversized locations by calculating pump performance before impeller trimming and calculating pump performance after impeller trimming to overcome the problem of large energy usage, and exploring the impact of impeller trimming on pump performance. The results of this research were effective head calculations carried out on the five systems by summing them in complex circuits to obtain a head of 61.72m and using two jumbo pumps with impeller trimming of 7.5% and operating in parallel, combined with safety factor and throttle valve adjustments, shows that the system can operate optimally and within safe limits. Trimming the impeller by 7.5% can save energy of 530 kWh or a saving cost of Rp. 28,627,510. per month
