耳轴销

耳轴销是耐火衬里钢包系统中的关键承载部件，设计为精密加工的圆柱形轴，与钢包耳轴环配合。它们将装满 molten metal 的钢包的全部重量传递到起重机吊钩或转塔机构，同时允许受控倾斜以进行浇注操作。这些销必须承受极端的热循环、高达数百吨的机械冲击载荷，以及来自炉渣和金属飞溅的腐蚀性环境。

耳轴销作为旋转轴和主要承载件。它们穿过焊接在钢包壳体上的耳轴环，其端部与提升机构中的轴承表面接合。在操作过程中，销承受压缩、剪切和弯曲应力，同时通过集成轴承表面或单独的轴承组件实现平稳旋转。其圆柱形几何形状均匀分布应力，而精确的公差确保钢包移动时最小间隙和振动。

Trunnion pins function as rotational axles and primary load carriers. They are inserted through trunnion rings welded to the ladle shell, with their ends engaging bearing surfaces in the lifting mechanism. During operation, the pins bear compressive, shear, and bending stresses while enabling smooth rotation through integrated bearing surfaces or separate bearing assemblies. Their cylindrical geometry distributes stress evenly, while precise tolerances ensure minimal play and vibration during ladle movement.
