The utility model discloses an all-hydrogen bell furnace, which comprises a convection plate and a fully sealed base. The top end of the fully sealed base is provided with a refractory heat layer, the one side of the fully sealed base is perforated with a hydrogen conveying pipe, the other side of the fully sealed base is perforated with a vacuum exhaust pipe, the top center of the fully sealed base is perforated with a frequency conversion motor, and the top of the frequency conversion motor is connected with gas through a shaft. A diffuser is arranged in the middle of the top of the refractory heat layer, and a steel coil is arranged on the top of the diffuser. A convection plate is arranged in the middle of the steel coil, and a convection air is arranged in the center of the convection plate. The full hydrogen bell furnace, hydrogen is fed into the inner cover through the hydrogen conveyor pipe, there is a gap between the coil and the coil, and some coils and some coils are clamped with convection plates, with convection holes in the middle. The gas circulation impeller is driven by the frequency conversion motor, and the air flow in the inner cover is agitated, so that the contact between hydrogen and the coil is more comprehensive.

全氢罩式炉
本技术涉及钢卷热处理
,尤其涉及全氢罩式炉。
技术介绍
全氢罩式炉是冷轧钢卷的重要退火设备,它以纯氢气作为保护气体,使得钢卷退火后表面比较光洁,同时大大提高了传热效率。现有的全氢罩式炉,多为圆形或方形,其内部要置入大量的钢卷,使其全密封底座的负重过大,可能会因负重原因导致其产生裂缝,而堆积后的钢卷,使氢气不能与之全面接触,会降低钢材的质量,且冷却方式有待加强。
技术实现思路
本技术的目的是为了解决现有技术中存在的缺点,而提出的全氢罩式炉。为了实现上述目的,本技术采用了如下技术方案:全氢罩式炉,包括对流板和全密封底座,所述全密封底座上端设有耐火热层,所述全密封底座一侧贯穿设有氢气输送管,所述全密封底座另一侧贯穿设有真空抽气管,所述全密封底座顶部中心贯穿设有变频电机,且变频电机顶部通过轴连接气体循环叶轮,所述耐火热层顶部中间设有扩散器,且扩散器顶部设有钢卷,所述钢卷中间设有对流板,且对流板中心设有对流空,所述全密封底座顶部通过液压夹钳活动连接内罩,且内罩外侧罩有冷却罩,所述冷却罩下端一侧设有废水管,所述冷却罩上端设有冷却风机,所述冷却罩内部顶壁中心贯穿设有水 ...
