Description
一种快速节能环保的金属连续熔化炉
技术领域
本实用新型属于金属冶炼设备技术领域，涉及一种金属熔化炉结构，具 体涉及一种快速节能环保的金属连续熔化炉。 背景技术
现有技术中连续铸造使用的金属材料熔化设备^主要是采用独立集中的 熔化炉和保温炉联合完成连续铸造过程，有色金属的熔化温度、保温温度和 升温温度均有所不同，它是由有色金属熔炼的工艺性所决定的，在现有的国 内外高压铸造、金属型铸造、砂型铸造和挤压铸造的企业中，通常采用燃气 或燃油的熔化炉进行集中熔化金属，用一台或多台保温炉进行配套使用，将 熔融的金属液用浇包或配送系统送入保温炉用于浇铸。由于熔化炉内的金属 熔液不断的使用，存量不断的减少，而不断的补充锭料，会使炉内温度急剧 下降，因此将炉温再次升高到设定温度，将所添加金属锭熔化后方可继续使 用。所以现有技术金属熔化大都采用这种间歇补救的作业方式进行大型、大 批铸件的连续铸造。这种方式的熔化炉在熔炼过程中处于非封闭状态，会因 燃烧能源排放出大量的二氧化硫、 一氧化碳等高温废气，热量损失大、能耗 高，存在着金属液易吸气和氧化，产品质量下降、劳动强度大、环境污染、 安全生产的可靠性降低，温度不均匀和连续作业较为困难的问题。 发明内容
本实用新型的目的是提供一种具有节能、快速、直接熔化功能并能提供连续铸造金属的熔化炉，在熔炼过程处于全封闭状态，不会有毒有害气体排 放，在进行金属熔化冶炼的过程中，通过熔化炉体外的自动推料装置将金属 锭连续推进炉内，然后再通过设置在熔化炉体内加热装置对排放在送料平台 的金属锭一边行进一边进行逐步加热，使即将熔融的金属锭从加热装置送料 平台倾斜流入熔化炉体内，经过在加热区加热装置不断的升温加热完全熔化 流向保温区，最后形成为适用浇铸、稳定的金属熔液。这种直接连续的熔化 方式及时补充了熔化炉内的金属熔液的存量，减少了因直接将室温内的金属 锭加入熔液中而使炉内熔液温度急剧下降造成的金属液不稳定的影响，可不 间断的提供浇铸使用，实现了节能、快速、直接熔化金属，解决了现有技术 金属熔化存在的热损失大、能耗高、金属液易吸气和氧化、温度不均匀和大 型、大批铸件连续作业较为困难的问题，减轻了劳动强度、改善了环境，提 高了产品质量和安全生产的可靠性。
本实用新型所采用的技术方案是， 一种快速节能环保的金属连续熔化
炉，包括熔化炉体、送料装置，所述的熔化炉体设有熔化区A和保温区B， 在熔化炉体的熔化区上部倾斜设置槽形通道的加热装置，加热装置一端与熔 化炉体的进料口外的送料装置连接，加热装置的槽形通道上平面为送料平 台，加热装置的槽形通道内设置有高温加热管，在熔化炉体的进料口处还设 有加料装置和自动推料装置，自动推料装置装有送料推杆；在熔化炉体的保 温区B上部设有用于保温的高温加热管和观察口，下部设有出液口及出液堵 头。
本实用新型快速节能环保的金属连续熔化炉，其特征还在于， 所述的加热装置采用耐高温铸铁材料。
所述的熔化炉体的熔化区和保温区的上部设有间隔墙，熔化区和保温区的底部做成便于流动的倾斜状。
所述熔化炉体的各个区域还装有用于监控温度的温度传感器。 本实用新型提供的快速节能环保的金属连续熔化炉，在进行金属熔化冶 炼的过程中，连续将添加的金属锭通过设置在熔化炉熔化区的上部的加热装 置直接加热快速升温，在将金属锭自动推进炉体内的过程中，由外向里逐渐 加热熔化，使即将熔融状态的金属锭从加热装置送料平台倾斜流入熔化炉体
内；经过在熔化区加热装置不断的升温加热完全熔化流向保温区，最后形成 为适用浇铸、稳定的金属熔液，这种直接连续的熔化方式及时补充了熔化炉 内的金属熔液的存量，减少了因直接将处于室温的金属锭加入熔液中而使炉 内熔液温度急剧下降造成的金属液不稳定的影响，可不间断的提供浇铸使 用，实现了节能、快速、直接熔化金属，解决了现有技术金属熔化存在的热 损失大、能耗高、金属液易吸气和氧化、温度不均匀和大型、大批铸件连续 作业较为困难的问题，减轻了劳动强度、改善了环境，提高了产品质量和安 全生产的可靠性。本实用新型在熔炼过程中处于全封闭状态，因此在熔化过 程中不存在有毒有害气体排放，整个熔炼过程达到废气的零排放，达到了国 家环保指标要求。 附图说明

下面结合附图和具体实施方式对本实用新型进行详细说明。
一种快速节能环保的金属连续熔化炉，如图l、图2所示，包括熔化炉 体1、送料装置2，所述的熔化炉体1设有熔化区A和保温区B，在熔化炉 体1的熔化区A上部倾斜设置槽形通道式加热装置3，加热装置3 —端与熔 化炉体1的进料口 4外的送料装置2连接，加热装置3的槽形通道上平面为 送料平台，加热装置3采用耐高温铸铁材料制成的槽形通道内设置高温加热 管5，在熔化炉体1的进料口 4处还设有加料装置10和自动推料装置6，自 动推料装置6装有送料推杆7;在熔化炉体1的保温区B上部设有用于保温 的高温加热管5和观察口 8，下部设有出液口 9及出液堵头12;熔化炉体l 的熔化区A和保温区B的上部设有间隔墙14，熔化区A和保温区B的底部 做成便于流动的倾斜状，熔化炉体的各个区域还装有用于监控温度的温度传 感器13。 '
使用本实用新型进行连续铸造生产时，在进行金属熔化冶炼的过程中， 先将金属锭11从加料装置10内取出排放在送料装置2的平台上，通过熔化 炉体1外的自动推料装置6的送料推杆7将金属锭11连续推进炉内，然后 再通过设置在熔化炉体l内熔化区的加热装置3，对排放在加热装置3上平 面送料平台的金属锭11进行直接加热，加热装置3通过高温加热管5通电 发热，可将熔化区炉内温度加热到78(TC高温，熔化区的加热装置3通过高 温加热管5加热的上平面送料平台与金属锭11直接接触传导热量，还通过 加热装置3槽形通道内设置的高温加热管5的热辐射向炉体内传导热量熔化 金属，通过熔化炉体1的各个区域装有的用于监控温度的温度传感器13，检 测和控制炉内各处温度，确保金属溶液的正常熔炼。当熔化区加热装置3末端处熔化炉体1一侧装有的温度传感器13测的 最末端的金属锭11温度达到50(TC时，外部自动推料装置6驱动送料推杆7 将熔化炉体1外的摆放的添金属锭11向前推进一锭，其作用力使排在最前 面的金属锭11，在加热装置3直接加温和炉内高温间接加热作用下成为即 将熔融状态的金属，顺着倾斜设置的加热装置3上平面送料平台直接流入熔 化炉1的熔化区A内，熔化区A的加热温度控制在780°C，经过在熔化区A 加热装置3不断的加热升温，完全熔化的浇铸金属液经倾斜的底部流动到相 对较低的保温区B，由于熔化炉体1的熔化区A和保温区B的上部设有间 隔墙14，保温区B通过上部设有用于保温的高温加热管5将温度控制在680 "C左右对金属熔液进行保温，通过保温区B通过上部设制的观察口 8观察金 属熔液状态，经过该区域装有的温度传感器13测得金属熔液稳定状态，最 后完全熔化成为适用的浇铸金属液后，拔出熔化炉体1保温区B下部位于倾 斜底部的出液口 9的出液堵头12实施浇铸。这种熔化方式及时补充了熔化 炉内的金属熔液的存量，减少了因直接将处于室温的金属锭加入熔液中而使 炉内温度急剧下降造成的金属液不稳定的影响的，可不间断的提供浇铸使 用，金属熔化实现了直接、快速、节能。由于本实用新型熔化炉的一端为进 料口，另一端为出液口，在熔炼过程中均是处于全封闭状态，因此在熔化过 程中不会有有害气体排放到空气中，实现了整个熔炼过程废气的零排放，完 全达到了国家环保指标要求。
