Recently, Shandong jute pipe industry produced 499 tons of q355c brand 140mm for the first time × 140mm, 160mm × The 160mm angle steel products were successfully rolled off the production line, realizing a breakthrough in the specifications and materials of angle steel products of the new medium-sized production line. After inspection, the appearance quality, mechanical properties and low-temperature impact energy indexes of the product are all qualified, meeting the standards and customer requirements, and will be used for the manufacturing of transmission towers for State Grid projects. At present, the products have been successfully delivered to a large iron tower company in Jiangsu Province.
Facing the downward pressure of the long product market, all departments of Shandong jute pipe industry cooperated with each other. On the basis of consolidating and expanding the structural advantages of the existing medium profile varieties, they made great efforts in the structural diversification and serialization, vigorously promoted the serialization development of angle steel products in the new area production line, actively met the personalized needs of high-end customers, deeply explored the efficiency potential of the production line, and improved the profitability of the varieties.
Due to the small order quantity of single products, the large number of specifications and materials involved, the fine control of dimensional accuracy, the frequent adjustment of roll change, and the high requirements of customers for the yield strength, tensile strength, elongation after fracture, low-temperature impact performance and surface quality of products, this production is very difficult. In this regard, the marketing, technology and production departments of the company cooperate with each other to strictly control the relevant smelting components and rolling temperature, so as to ensure the stability of the finished product strength index and excellent low-temperature impact performance.
