电工钢连退涂层机组带钢悬垂曲线模型的计算与分析

Calculation and analysis of strip suspension curve model in the continuous annealing and coating line

在无取向电工钢连退涂层机组中,带钢退火后会进行绝缘涂层的涂覆,为了保证涂层质量,避免带钢表面尚未干燥的涂液被破坏,涂层后的带钢采用悬垂的过钢方式进入漂浮炉,本文以电工钢连退涂层机组涂机与漂浮炉中间的悬垂带钢为研究对象,详细阐述了带钢悬垂曲线模型的建立过程,并且对4种不同工况下带钢的悬垂曲线进行了计算与分析,为机组的合理布置提供了理论依据.

In the continuous annealing and coating line for non-grain oriented silicon steel,the insulation coating should be coated on the strip surface after annealing.To ensure the quality of coating and avoid the undried coating liquid on the strip surface been destroyed,the coated strip was suspended to through into the floating furnace.This paper researched the strip between the coater and the floating furnace,and described the process of establishing the strip suspension curve in detail,calculating and analyzing four suspension curves under different working conditions,which can provide theoretical basis for reasonable arrangement of the unit.
