【技术实现步骤摘要】
本专利技术涉及一种高温加热炉,尤其涉及一种锯条高温连续热处理炉。
技术介绍
金属锯条经加工成型后都必须经过热处理,以提高它的性能。为了提高提高生产 效率,锯条往往是在截成成前进行连续热处理。如图1所示为现有的锯条热处理炉截面图, 它包括外壳101和填充在外壳101内的保温棉102,保温棉102的中心布设沿锯条行进方向 设置的加热组件。如图2和图3所示,加热组件包括相互穿套的加热管103和马弗管105,加热管103 在外部,由白钢玉陶瓷制成,外壁螺旋缠绕有加热电阻丝104,马弗管105位于截面呈六边 形,内腔中设有由托架106支撑的陶瓷引导107,在锯条加热过程中,沿着陶瓷引导107行 进,同时也可以在外壳101底部垫耐火砖108,让加热组件更为牢固。为了测量加热温度,热 电偶109穿过外壳101、保温棉102和加热管103,底端位于马弗管105和加热管103之间 的间隙。由于加热电阻丝缠绕在加热管103上,无法将热量迅速传送至马弗管105,而且热 电偶检测的是马弗管105与加热管103之间间隙内的温度,而不是马弗管105内的温度,检 测的温度与锯条温度有差距, ...
【技术保护点】
1.一种锯条高温连续热处理炉,包括外壳、保温层、热电偶以及保温层内的加热模块,其特征在于,所述的加热模块包括沿锯条行进方向设置的加热室、竖直穿过保温层伸入加热室的加热棒、加热室内的马弗管以及马弗管内由托架支撑的陶瓷引导,所述的加热室由若干重复单元依次拼接组成,每个重复单元由底座、两侧对称设置的边墙以及竖直穿过保温层的顶盖围成,所述的边墙包括侧立部和设于侧立部顶端内侧的平檐部,其中侧立部底端内侧面与底座密封配合,平檐部内侧面为竖直平面,并与顶盖的侧壁密封配合,侧立部内侧两端设有用于支撑顶盖的挡板,两挡板之间的平檐部上设有供加热棒穿过的通孔。
