Specific embodiment
Principle of the invention and feature are described below in conjunction with accompanying drawing, example is served only for explaining the present invention, and
It is non-for limiting the scope of the present invention.
Embodiment：As illustrated in fig. 1 and 2, the tundish for being easy to dismounting and cleaning of the present embodiment includes tundish inclusion 1 and bag
Lid 2, above-mentioned tundish inclusion 1 is the shell structure of upper end open, and 1 one side wall outwardly convexs of above-mentioned tundish inclusion form punching
Area 11 is hit, above-mentioned clad 2 is detachably arranged in the above-mentioned openend of tundish inclusion 1, and the above-mentioned impact zone of the correspondence of above-mentioned clad 2
It is provided with breach 21 at 11 position, the bottom of above-mentioned impact zone 11 is removably inserted with oblique barricade 3, and above-mentioned oblique barricade 3 is upper
The direction that end faces away from above-mentioned impact zone 11 is obliquely installed, and the above-mentioned both sides of oblique barricade 3 are plugged on 11 liang of above-mentioned impact zone respectively
In the wall of side side, an impact chamber 4, the breach 21 are surrounded between above-mentioned oblique barricade 3 and the side wall of impact zone 11 and bottom wall jointly
In the top of the impact chamber 4, the above-mentioned bottom of tundish inclusion 1 offers the middle water containing opening 5 through it.
Round and smooth transition cambered surface 111 is provided between the side wall and bottom wall of above-mentioned impact zone 11.
Bottom is provided with top retaining wall 211 at above-mentioned breach 21, and above-mentioned top retaining wall 211 is located in above-mentioned impact chamber 4, and it is above-mentioned on
The two ends of barricade 211 contradict on the both sides inwall of above-mentioned impact zone 11 respectively.
Above-mentioned oblique barricade 3 is provided with diagonal brace 31 away from the side of above-mentioned impact zone 11, above-mentioned diagonal brace 31 away from oblique barricade 3 one
End is plugged on the above-mentioned bottom wall of tundish inclusion 1.
Above-mentioned diagonal brace 31 is provided with multiple, and the above-mentioned oblique barricade 3 that is arranged on that is uniform and being spaced deviates from the impact zone 11
Side.
