環(huán)形加熱爐設計淺析
A Brief Analysis of Designing of Rotary Hearth Heating Furnace
-
摘要: 環(huán)形加熱爐在鋼管生產中起著重要的作用,其設計是否合理,將直接影響鋼管產品的質量和鋼管軋制生產節(jié)奏。介紹了如何合理確定環(huán)形加熱爐的設計參數(shù)和布料角,以及爐底砌筑結構設計、爐底與爐膛中心差值的選取方法等,并提出了新的環(huán)形加熱爐烘爐方案。實際應用表明,所設計的平均直徑24m環(huán)形加熱爐運行工況良好。Abstract: Since the rotary hearth heating furnace plays a critical role in the manufacturing process of steel pipes,whether its design is proper or not will directly affect pipe quality and the pipe rolling cycles.Elaborated here in the article are proper determination of the design data and the billet arrangement angle in the hearth,the design of the furnace bottom masonry structure as well as the selection method for the D-value of the hearth center,etc.Also put forward is a new feasibility solution for drying out of the furnace.The actual operation of the furnace as designed with the average diameter of 24 m are satisfactory.
