    炉体结构描述:

    5.1机械结构原理说明

    炉体采用钢壳磁轭炉体,金属熔液的出口通道“浇口”设在电炉底部。(高铝石墨质或氧化锆质水口)由于金属在熔炼过程中,杂质和熔渣均浮在液面;底注式浇注可避免杂质和熔渣进入铸件型腔,大大减少废品出现。 钢水出口连接有塞杆动作机构;塞杆动作机构包括塞棒、气缸和传动杠杆,塞棒底部形状与钢水出口形状相适配,且塞棒底部为由上至下渐缩形;气缸驱动传动杠杆沿一固定轴转动,传动杠杆带动塞棒作上升或下降动作。用塞杆动作机构的上升或下降运动来控制出钢口的开、关或开度,精确控制出钢点和出钢流量及出钢流速,

     

     

     


    塞杆动作机构包括塞棒2、气缸3和传动杠杆4,气缸3连接传动杠杆4的一端,气缸的底部固定;塞棒2连接传动杠杆4的另一端,塞棒2的底部形状与钢水出口形状相适配,且塞棒2的底部为由上至下渐缩形;气缸3驱动传动杠杆4沿一固定轴转动,传动杠杆4带动塞棒2作上升或下降动作。其特征在于钢水出口横截面为圆形,塞棒2的底部为圆椎形。传动杠杆4的另一端固定连接有悬挂套管5,悬挂套管5用于将塞棒2悬挂于传动杠杆4上。塞杆动作机构还包括旋转轴承6,旋转轴承6连接悬挂套管5和塞棒2之间。塞杆动作机构还包括支架7,支架7上固定连接有套筒型调正器(8);还包括缓冲弹簧10和位置固定杆9,悬挂套管5的下端与缓冲弹簧10的上端固连,缓冲弹簧(10)的下端与旋转轴承(6)的内圈固连,旋转轴承6的外圈与位置固定杆(9)相连接。

    Fifth , the furnace structure description:

    5.1 mechanical principles described structure

    The furnace body adopts a steel shell yoke furnace body, and the outlet channel "gate" of the metal melt is arranged at the bottom of the electric furnace. ( High-aluminum graphite or zirconia nozzle ) Since the metal is in the smelting process, impurities and slag float on the liquid surface; the bottom-injection casting can prevent impurities and slag from entering the casting cavity, greatly reducing the occurrence of waste. The steel water outlet is connected with a plug rod action mechanism; the plug rod action mechanism comprises a plug rod, a cylinder and a transmission lever, the bottom shape of the plug rod is adapted to the shape of the molten steel outlet, and the bottom of the plug rod is tapered from top to bottom; the cylinder drive transmission The lever rotates along a fixed axis, and the transmission lever drives the plug to raise or lower. Use the rising or falling movement of the plug rod action mechanism to control the opening, closing or opening of the taphole, and precisely control the tapping point and tapping flow rate and the tapping flow rate.

     

    The plug rod action mechanism comprises a stopper rod 2, a cylinder 3 and a transmission lever 4, the cylinder 3 is connected to one end of the transmission lever 4, and the bottom of the cylinder is fixed ; the stopper rod 2 isconnected to the other end of the transmission lever 4, the bottom shape of the stopper rod 2 and the molten steel outlet The shape is adapted, and the bottom of the stopper rod 2 is tapered from top to bottom; the cylinder 3 drives the transmission lever 4 to rotate along a fixed axis, and the transmission lever 4 drives the stopper rod 2 to ascend or descend. It is characterized in that the steel water outlet has a circular cross section, and the bottom of the stopper rod 2 has a circular cone shape. The other end of the transmission lever 4 is fixedly connected with a suspension sleeve 5 for suspending the stopper rod 2 from the transmission lever 4. The stopper action mechanism further includes a rotary bearing 6 that connects between the suspension sleeve 5 and the stopper rod 2. The plug action mechanism further includes a bracket 7 to which the sleeve type adjuster (8) is fixedly coupled; a buffer spring 10 and a position fixing rod 9 are further fixed, and the lower end of the suspension sleeve 5 is fixed to the upper end of the buffer spring 10 The lower end of the buffer spring (10) is fixed to the inner ring of the rotary bearing (6), and the outer ring of the rotary bearing 6 is connected to the position fixing rod (9)
