在冷轧成品和精整机组上为了获得带钢边部的高质量,通常采用切边剪和废边处理装置的组合配置。针对冷轧簿带钢废边处理用的压块机和卷球机,从其工作原理、设计能力核算、制造的难度和经济性、使用维护实绩等方面进行全面对比和分析,得出压块机适用于速度相对较低且废边丝厚度和强度适当的生产线;废边卷球机适用于机组速度较高且废边丝厚度范围更广的生产线,两者对于高强钢的优势不明显,就制造和维护成本而言,废边卷球机相对压块机具有优越性。
In cold rolled products and finishing units, in order to obtain the high quality of the strip edges, it is common to use a combination of trimming and scrap processing devices. Aiming at the briquetting and ball rolling machines used for the scrap processing of cold-rolled steel strip, the author makes a comprehensive comparison and analysis from the aspects of its working principle, design ability calculation, manufacturing difficulty and economy, service maintenance performance and so on, The machine is suitable for the production line with relatively low speed and waste edge wire thickness and strength. The waste edge ball machine is suitable for the production line with higher unit speed and wider waste edge wire thickness. The advantages of the two are not obvious for high strength steel, In terms of manufacturing and maintenance costs, the side of the ball rolling machine relative to the briquetting machine has the advantage.
