It also introduces the application prospects and benefits of high-speed steel rolls by summarizing the use conditions, accident handling and use effects of the fully continuous bar production line in the third rolling operation area of the steel plant during the use of high-speed steel […]
Application and improvement of high-speed steel rolls in hot-rolled strip production
Description: This paper studies and analyzes the application of high-speed steel rolls in the production of hot-rolled strips, and predicts the broad prospects of high-speed steel rolls with the help of wear resistance, chemical composition, heat resistance and mechanical properties. Solutions and good suggestions are put forward for the problems existing in the production of […]
Material selection for high-speed wire mill roll
Description：High speed wire mill precision rolling unit is an important factor to ensure the high precision rolling, so high speed wire rolling mill must adopt tungsten carbide carbide roll ring, otherwise the rolling speed and the wear resistance of roll ring will not be guaranteed. So far, no material can replace the tungsten carbide carbide […]
Formation and Control of Red Scale and Copper Brittle Defects in Hot Rolled Strip Production
Red scale and copper brittle defects are common defects in the production process of hot-rolled strip steel, especially the red scale defect of high-silicon steel grades, which has always been one of the important reasons that plague the surface quality of strip steel. In recent decades, scholars from Japan and other countries have made some […]
Material selection of rolling mill rolls used in large and medium section steel mills
Description：In view of the complex section of large and medium-sized steel and the different main properties of the rolling mill rolls in each stand of the rolling mill, this paper points out the factors that should be considered in the selection of roll materials for the rough rolling unit, intermediate rolling stand and finishing rolling […]
Solve the problem of peeling off of the oxide film on the surface of the rolling mill rolls
Description: The peeling off of the oxide film on the surface of the rolling mill rolls is an important factor affecting the surface quality of the strip. Effective control of the peeling off of the oxide film on the roll surface requires a systematic and comprehensive solution Keyword: Rolling mill rolls In a 1780 mm […]
