Rebar minimill set for South Korea YK Steel, South Korea, has commissioned SMS group to supply a new minimill with integrated melting, casting and rolling, and including all electrical and automation systems.

In addition to being a strategic decision to underscore the company’s growth plans, the new plant project aims to achieve more sustainable production. To produce the steel, YK Steel plans to use a 115-ton DC Edge® electric arc furnace and an Aura® charging system, which is operated with 100 per cent steel scrap. The five-strand caster, which will produce square billets 150mm thick, can achieve casting speeds of up to 4m/min by using Convex mould technology. The cast billets are conveyed into the downstream rolling mill via a hot-charging roller table. This is connected to a walking beam furnace that offers a production capacity of 140 tons of billets per hour and is fitted with low-NOx recuperative burners. The rolling mill consists of 18 new housingless stands and a water cooling system for controlling the rolled stock temperature and for quenching. YK Steel will use the new plant to produce reinforcing steel with diameters ranging from 10 to 35mm. The products manufactured in the minimill will be sold as part packages from 6 to 12m long with a maximum weight of 450 to 550kg, and large packages weighing up to two tons.

Instead of relocating and upgrading an existing plant, originally planned at the end of 2021, YK Steel opted for a completely new minimill, allowing it to benefit from the latest technologies. The minimill will start production in 2025 at the company’s Dangjin site.
