Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of can improve continuous casting tundish conflux vortex TVS and the continuous casting tundish of the inherent quality of continuous casting billet effectively by inhibition, destruction conflux vortex.
The technical solution of the utility model is achieved in that continuous casting tundish conflux vortex TVS, comprise refractory material matrix, on the upper surface of described refractory material matrix, be provided with strip projected parts, and in described refractory material matrix, there is the fluid passage to lower surface from upper surface.
Above-mentioned continuous casting tundish conflux vortex TVS, the height of described refractory material matrix is 100～200mm.
Above-mentioned continuous casting tundish conflux vortex TVS, the upper surface of described refractory material matrix is plane or the conical surface.
Above-mentioned continuous casting tundish conflux vortex TVS, described refractory material matrix is cylindrical refractory material matrix, described fluid passage is along the axial setting of described cylindrical refractory material matrix.
Above-mentioned continuous casting tundish conflux vortex TVS, offers the hole with the conducting of described fluid passage on the side of described cylindrical refractory material matrix.
Above-mentioned continuous casting tundish conflux vortex TVS, the upper bottom surface of described cylindrical refractory material matrix is upper surface, described strip projected parts is radially uniformly distributed setting on the upper bottom surface of described cylindrical refractory material matrix.
Above-mentioned continuous casting tundish conflux vortex TVS, the wall thickness between described fluid passage and the side of described cylindrical refractory material matrix is 100mm.
The continuous casting tundish with above-mentioned continuous casting tundish conflux vortex TVS, described continuous casting tundish conflux vortex TVS is placed in continuous casting tundish, and is positioned at continuous casting intermediate inlet place, described fluid passage and described continuous casting intermediate inlet fluid communication.
Above-mentioned continuous casting tundish, the axis of described fluid passage and the dead in line of described continuous casting intermediate inlet.
The beneficial effects of the utility model are: the new continuous casting tundish conflux vortex TVS of this practicality is positioned over continuous casting intermediate inlet place, can eliminate or suppress conflux vortex, improves the inherent quality of continuous casting billet, the rate of reducing the number of rejects and seconds.
