Example Embodiment
[0030] Example one: such as figure 1 As shown, the light-weight long-life tundish cover in this embodiment includes a steel structure, a refractory material filling layer 1, a slag hole 2 and a stopper hole 3. The steel structure includes a stainless steel frame 4 and a stainless steel frame. A stainless steel mesh 5, the lower side of the stainless steel mesh 5 is evenly connected with anchors 6, the middle of one side of the stainless steel mesh 5 is provided with a slag hole 2, and the outer edge of the slag hole 2 is provided with a stainless steel frame 7 The stainless steel mesh 5 is also provided with a number of stopper holes 3, and the outer edge of the stopper hole 3 is provided with a stainless steel frame 7. The stopper hole 3 can be used as an observation hole and a temperature measurement hole at the same time. The upper and lower sides of the stainless steel mesh 5 are both light-weight refractory filled layers 1.
