The paper describes the main stages of the development of sectional and shaped profiles by the JSC “EVRAZ NTMK” over the past years. The plant operates three longitudinal rolling mills, each of which has been producing both construction metal structures and transport products for many decades. Every year, market competition causes increased consumer requirements toward product quality and requires expansion of the product assortment. Therefore, developing new profiles is an ongoing process at the JSC “EVRAZ NTMK.” The following transport profiles have been developed: stirrup stop bar, rail pad bar R-65, insulated joint core bar ApATeK R-65 MK-BO, guard-rail angle SP850, subway conductor rail, I-beam No. 19 used in the construction of a center girder of the pivoted unit of the rail cars, and a non-standard I-beam 13C1 manufactured according to the technical agreement with the Research and Production Enterprise (RPE) “Uralvagonzavod.” Due to consumer requests, the heavy-section and rail-and-beam shops of the JSC “EVRAZ NTMK” started production of the U-channel line, since such series is more preferable when manufacturing metal constructions compared to V-channel sloping along the inner side of the flange, previously produced at the JSC “EVRAZ NTMK.” In recent years, the railand-beam shop started production of the entire line of crane rails. In just the past 5 years, over 60 standard I-beam sizes have been implemented under the wide-flange beam rolling shop conditions according to various standards, including a foreign ASTM A6/A6M-2017a standard and BS EN 10365–2017 standard, as well as GOST R 57837–2017 developed by EVRAZ together with the Central Research Institute of Building Structures (TsNIISK) named after V. A. Kucherenko. The process of developing new profiles at the JSC “EVRAZ NTMK” continues. In 2020 alone, it is planned to start production of more than 20 new types and nominal sizes of the hot-rolled sectional and shaped profiles.

新型轧材生产——以客户为中心

该论文描述了 JSC “EVRAZ NTMK” 在过去几年中开发截面和异形型材的主要阶段。该工厂运营着三台纵向轧机，每台轧机几十年来一直生产建筑金属结构和运输产品。每年，市场竞争都会导致消费者对产品质量的要求不断提高，并需要扩大产品种类。因此，开发新的配置文件是 JSC “EVRAZ NTMK” 的一个持续过程。开发了以下运输型材：箍筋止动杆、轨道垫杆 R-65、绝缘接头芯杆 ApATeK R-65 MK-BO、护栏角钢 SP850、地铁导电轨、工字钢 19 号用于建造轨道车枢转单元的中心梁，以及根据与研究和生产企业（RPE）“Uralvagonzavod”的技术协议制造的非标准工字梁 13C1。由于消费者的要求，JSC“EVRAZ NTMK”的厚型材和钢梁车间开始生产 U 型槽钢，因为与 V 型槽钢相比，这种系列在制造金属结构时更可取。法兰的内侧，之前在 JSC “EVRAZ NTMK” 生产。近年来，钢梁车间开始生产全线起重机钢轨。仅在过去的5年中，根据各种标准，包括国外ASTM A6/A6M-2017a标准和BS EN 10365-2017标准，在宽翼缘梁轧制车间条件下实施了60多种标准工字钢尺寸，以及由 EVRAZ 与以 VA Kucherenko 命名的中央建筑结构研究所 (TsNISK) 共同开发的 GOST R 57837-2017。在 JSC “EVRAZ NTMK” 开发新配置文件的过程仍在继续。仅2020年，就计划投产20多种新型号和公称尺寸的热轧异型材和异型材。
