Revamping of 80T DC Electric Arc Furnace with Shaft technology

  1. Introduction

[CE 1.1]

Title:Revamping of 80T DC Electric Arc Furnace with Shaft Technology

Duration: 15 May 2013 to 4 August 2013

Location: Singapore

Organization: Natsteel Holdings Pte Ltd, Singapore.

Position: Project Engineer

  1. Background

[CE 1.2]

NatSteel traces its lineage to 1961 when it was incorporated as National Iron and Steel Mills. A pioneer and key partner in Singapore's nation-building efforts, our products are used in most construction projects island-wide, from the iconic Changi International Airport to the public housing that is the trademark of Singapore’s landscape.Singapore is home to NatSteel’s headquarters as well as its flagship plant, which boasts one of the largest single downstream rebar fabrication operations in the world. The Singapore plant is the only local steel mill with an integrated upstream and downstream operation, where steel is manufactured through recycling scrap, and fabricated according to customers’ needs. Our subsidiary, NatSteel Recycling, is also Singapore’s largest metal recycler.While typical steel mills operating electric arc furnaces use about 400 to 450 kilowatt hours of energy to produce a tonne of steel, NatSteel does the same consuming 30% less energy As the only steel mill in Singapore, NatSteel uses 100% recycled metal scrap that undergoes stringent radiation checks. This ensures the delivery of premium, high-quality reinforcement steel solutions that are sustainable and safe.

[CE 1.3]

The main objective of the upgrade was to increase productivity from 2400 tons/ per day of steel produced to 2560 ton/per day, thus increasing the output from 750K to 800K tpa. Having a net saving of $1.1M/year.Reduce the unplanned downtime of the equipment from 9% per month to 6%. Reduce maintenance cost from $11/mt to $9/mt resulting in a cost saving of $1.4M/year. Increase hot charge of steel billets produced for Merchant Bar Mill (MBM) by 2.5%, thereby increasing reheating furnace capacity from 90 tph to 120 tph as well as reducing fuel consumption from 24 lit/mt to 12 lit/mt resulting in a saving of $216K/year (value based on $0.90/lit in 2013)

[CE 1.6] Duties:

  • I conducted the feasibility study for projects covering availability and reliability improvement and new equipment installation.
  • I did the preparation of the project schedule, and resource management (equipment, tools, and manpower).
  • I drove health and safety, commercial outcomes, procurement, engineering, and people management across maintenance projects.
  • I coordinated the preparation of cost estimates, tender submissions, technical documentation, and client reports and monitored project progress and resourcing.
  • I conducted the design and engineering reviews and owned the execution and delivery of the projects.
  • I monitored site progress as well as ensured the project meets legislative and health and safety requirements.
  • I managed the complete cycle of production and energy improvement projects from inception to commissioning.
  • I supervised and inspected the installation, commissioning, and modification of equipment while executing CAPEX projects.
  • I conducted the safe operating procedure and risk assessments and supervised the technicians.
  • I conducted weekly project progress updates and reporting.

This ensures the delivery of premium, high-quality reinforcement steel solutions that are sustainable and safe.Natsteel produces about 2560 mt of steel, which goes through a refining process before it is cast into billets. Slag is produced during the refining process which amounts to about 1-1.5% of steel produced every day. Refining is the process where raw molten steel is converted to different steel grades based on carbon content. This slag is usually sent to authorized environmental agencies. The slag produced is very fine and hence they are soaked in a pool of water before they are transported
