Primetals Technologies reports that South Korean Hyundai Steel has issued final acceptance certificates for two long-rolling mills—a large bar mill and a small bar and wire rod mill—it supplied for its plant in Dangjin.
A press release said that the large bar mill is designed for annual capacity of about one million metric tons. It includes a duo-reversing breakdown stand and a finishing train with rolling/sizing stands. It will also provide billets to be further processed in the other new smaller mill.
Per the release, the small bar and wire rod mill has annual capacity of 800,000 metric tons. Designed to roll 160 tons per hour, the small bar and wire rod line will have the highest production rate for a combination mill. It employs low-temperature rolling technology designed to improve the metallurgical structure and mechanical properties of end products and to enhance flexibility during the rolling operation. Special mechatronics packages and an integrated automation solution ensure the necessary high product quality throughout the plant.
Hyundai Steel is part of the Hyundai-Kia Automotive Group, which has six production facilities in South Korea and one in China. Its order with Primetals Technologies included a continuous bloom casting machine designed to produce 1.1 million metric tons of blooms per year. That operation received final acceptance in 2017.
