一、前言坯料由两面进行加热的连续式加热炉的炉膛布置有很多水冷却的滑钢管和横支柱水管,这不仅造成大量的热损失,而且降低炉子的热效率,消耗大量的冷却水,同时也降低了炉膛的温度,影响着坯料加热的均匀性和炉子的生产能力。根据我公司各种连续式加热炉的测定调查结果来看,炉底水管表面积占炉底有效面积的 I. INTRODUCTION The continuous heating furnace with billet heated from both sides is equipped with a lot of water-cooled sliding steel pipes and horizontal strut pipes, which not only cause a lot of heat loss, but also reduce the thermal efficiency of the furnace and consume a large amount of cooling water, meanwhile Reduce the temperature of the furnace, affecting the uniformity of billet heating and furnace production capacity. According to my company a variety of continuous heating furnace measurement survey results, the bottom surface of the water pipe floor area accounted for the effective area
