The steel industry faces growing demands to meet construction needs\nwhile simultaneously reducing energy consumption and the environmental\nimpact of production processes. One technology being utilised to support\nsteel production through the use of recycled materials is the Electric\nArc Furnace (EAF).<\/p>\n
EAF technology uses electrical energy to melt selected steel scrap.\nThis material then undergoes a purification process before being shaped\ninto steel products that meet established specifications and\nstandards.<\/p>\n
The use of scrap allows steel that has reached the end of its useful\nlife to re-enter the production cycle. This cycle represents an\napplication of the circular economy, as materials can be used,\ncollected, recycled, and reprocessed into new products.<\/p>\n
Utilising scrap can also reduce the need for primary raw materials\nand the amount of material that ends up as waste. However, steel\nproduction emission levels are determined not only by furnace technology\nbut also by the source of electricity, process efficiency, raw material\nand waste management, and transportation.<\/p>\n
In the EAF process, scrap is melted using electrical energy through\nelectrodes at temperatures that can reach approximately 1,600 degrees\nCelsius. Because the material may contain various elements and\nimpurities, the chemical composition of the steel is controlled through\na refining process before being adjusted to product specifications.<\/p>\n
One steel producer using EAF technology is PT Garuda Yamato Steel\n(GYS), which operates production facilities in Cikarang, Bekasi Regency,\nWest Java. The company produces hot-rolled steel profiles for\nconstruction and infrastructure needs.<\/p>\n
Products manufactured include H-Beams, IWF (Wide Flange), Channels\n(UNP), and Equal Angles. These steel profiles are used for various\nstructural requirements, including buildings, warehouses, bridges,\nindustrial facilities, and infrastructure.<\/p>\n
Each type of profile serves a different function in construction.\nH-Beams and IWF can be used as beams or columns based on structural\ncalculations, while Channels and Equal Angles can be used for secondary\nframes, stiffeners, supports, or connection parts.<\/p>\n
Therefore, the selection of steel must consider dimensions, weight\nper metre, thickness, grade, mechanical characteristics, and product\nstandards. This information serves as the basis for ensuring materials\nmeet the technical requirements and specifications of a project.<\/p>\n
According to company materials, several of GYS\u2019s hot-rolled steel\nproducts have a Domestic Component Level (TKDN) of more than 90 per\ncent, including WF-Beams, H-Beams, U-Channels, and Angles.<\/p>\n
The President Director of PT Garuda Yamato Steel, Tony Taniwan,\nstated that innovation and sustainability are key aspects considered by\nthe company in its production activities.<\/p>\n
\u201cThe company\u2019s focus on innovation and sustainability ensures that\nGYS products meet applicable standards while contributing to national\ninfrastructure projects,\u201d said Tony.<\/p>\n
The use of steel with recycled content can also be a consideration in\nprojects implementing green building criteria, particularly regarding\nmaterial use and carbon footprint. However, sustainability assessments\nmust look at the entire material lifecycle, including energy sources,\nproduction processes, waste management, transportation, usage period,\nand the ability of the steel to be recycled again.<\/p>\n
For projects requiring large quantities of material, production\ncapacity, quality consistency, certification, product standards, and\ntechnical documentation are several factors that must be verified before\nprocurement. Consequently, the choice of producer should not be based\nsolely on claims regarding scale or company advantages, but must be\naligned with the specific requirements and structural needs of the\nproject.<\/p>", "url": "https:\/\/jawawa.id\/newsitem\/steel-industry-utilises-eaf-technology-to-reduce-carbon-emissions-1788519492", "image": "" }, "sponsor": "Okusi Associates", "sponsor_url": "https:\/\/okusiassociates.com" }
