台车退火炉炉门平面尺寸较大,门关闭后在门与门框间存在的间隙会形成较多的炉气沿上侧间隙外溢及冷空气沿下侧边缘流入的现象。从而使炉门附近料温明显偏低,影响退火质量。为解决门隙漏气现象可采用炉隙涂封耐火泥,用有水平位移分量的斜导轨装置或门关闭后加水平撑紧力机构等方式,但密封效果仍不够理想。现介绍一种能作水平位移的 Larger furnace annealing furnace door flat size, the door is closed, the gap between the door and the door frame will form more gas along the upper gap overflow and cold air along the lower edge of the inflow of the phenomenon. So that the material temperature near the oven door was significantly lower, affecting the quality of annealing. In order to solve the door gap leakage phenomenon, grate gap can be used to coat refractory mud, inclined guide rail device with horizontal displacement component or horizontal tensioning mechanism with door closed, but the sealing effect is still not satisfactory. Now introduce a kind of horizontal displacement
