摘要: 介紹了熱連軋無縫鋼管生產(chǎn)工藝布置中芯棒冷卻區(qū)的設(shè)備組成；根據(jù)不同結(jié)構(gòu)的芯棒移送設(shè)備，將芯棒冷卻區(qū)設(shè)備分為步進(jìn)梁式、曲柄搖桿式和升降翻板式3類，并對比分析了各自的優(yōu)缺點(diǎn)。分析認(rèn)為：步進(jìn)梁式結(jié)構(gòu)工藝集成性高、控制簡單，曲柄搖桿式結(jié)構(gòu)的點(diǎn)檢、維護(hù)方便，而升降翻板式結(jié)構(gòu)的投資成本低；在設(shè)計芯棒冷卻區(qū)設(shè)備的布置方案時，應(yīng)綜合考慮各類結(jié)構(gòu)的優(yōu)點(diǎn)確定設(shè)計方案。Abstract: Elaborated in the paper are the equipment composition of the mandrel bar cooling area in the process layout of the mandrel mill plant for hot-rolled seamless steel pipes. According to their different structures， the mandrel bar transfer devices in the area fall into three types，i.e.，the walking-beam，the crank & rocker，and the lifting flap. The advantages and disadvantages of each of the three types are compared and analyzed. As a result，it is identified that the walking-beam structure features high technological integrity and easy control，the crank & rocker mechanism is advantageous in easy point-check and maintenance， and the lifting flap structure stays with high investment effectiveness. When designing the layout of the mandrel bar cooling area，effectively integrating the above mentioned advantages and disadvantages and of the different transfer units should be considered.
