Summary of the invention
Technical matters to be solved by this invention is to provide a kind of steel plant continuous casting two metamerism roller water test units, utilize this test unit to do the hydraulic testing to two metamerism rollers, while avoiding two metamerism roller work, leak, guarantee the cooling effect of equipment, improve the product quality of continuous casting billet, reduced overhaul of the equipments cost.
For solving the problems of the technologies described above, steel plant continuous casting two metamerism roller water test units of the present invention comprise water tank, three valve plates, three block pressur plates, six roots of sensation stay-bolt and hydraulic power unit, described three valve plates are respectively equipped with Inlet and outlet water passage and described water tank end face is located at interval, described six roots of sensation stay-bolt one end respectively activity is located at described water tank end face both sides and is positioned at described three valve plate positions, described three block pressur plate two ends have through hole and are inserted in respectively two stay-bolts of described three valve plate both sides, the described six roots of sensation stay-bolt other end is screwed with respectively nut, the inlet channel of described hydraulic power unit connects described water tank bottom, outlet conduit connects respectively the intake tunnel of described three valve plates.
Further, this test unit also comprises three rubber gaskets, and described three rubber gaskets are interval with respectively two through holes and are located at described three valve plate end faces, and two through holes of described rubber gasket are communicated with respectively the Inlet and outlet water passage of described valve plate.
Because steel plant continuous casting two metamerism roller water test units of the present invention have adopted technique scheme, be that this device comprises water tank, three valve plates, three block pressur plates, six roots of sensation stay-bolt and hydraulic power unit, three valve plates are respectively equipped with Inlet and outlet water passage and water tank end face is located at interval, six roots of sensation stay-bolt one end respectively activity is located at water tank end face both sides and is positioned at three valve plate positions, three block pressur plate two ends have through hole and are inserted in respectively two stay-bolts of three valve plate both sides, the six roots of sensation stay-bolt other end is screwed with respectively nut, the inlet channel of hydraulic power unit connects water tank bottom, outlet conduit connects respectively the intake tunnel of three valve plates.This test unit is done the hydraulic testing to two metamerism rollers, while avoiding two metamerism roller work, leaks, and guarantees the cooling effect of equipment, has improved the product quality of continuous casting billet, reduces overhaul of the equipments cost.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the present invention is described in further detail:
Fig. 1 is the structural representation of steel plant continuous casting two metamerism roller water test units of the present invention;
Fig. 2 is the side view of Fig. 1.
Embodiment
As depicted in figs. 1 and 2, steel plant continuous casting two metamerism roller water test units of the present invention comprise water tank 1, three valve plates 2, three block pressur plates 4, six roots of sensation stay-bolt 3 and hydraulic power unit 6, described three valve plates 2 are respectively equipped with Inlet and outlet water passage and described water tank 1 end face is located at interval, described six roots of sensation stay-bolt 3 one end respectively activity are located at described water tank 1 end face both sides and are positioned at described three valve plate 2 positions, described three block pressur plate 4 two ends have through hole and are inserted in respectively two stay-bolts 3 of described three valve plate 2 both sides, described six roots of sensation stay-bolt 3 other ends are screwed with respectively nut 5, the inlet channel of described hydraulic power unit 6 connects described water tank 1 bottom, outlet conduit connects respectively the intake tunnel of described three valve plates 2.
Further, this test unit also comprises three rubber gaskets 7, and described three rubber gaskets 7 are interval with respectively two through holes and are located at described three valve plate 2 end faces, and two through holes of described rubber gasket 7 are communicated with respectively the Inlet and outlet water passage of described valve plate 2.Arrange when rubber gasket 7 is seated three valve plates 2 to continuous casting two metamerism rollers 9 effective protection is provided, avoid the damage of three bearing seats 8 of continuous casting two metamerism rollers 9.
In this device, hydraulic power unit can be made up of motor, water pump, retaining valve, safety valve, throttling valve, tensimeter, flowmeter and filter for molten etc., and hydraulic power unit is realized the water of water tank is injected in continuous casting two metamerism rollers with certain pressure by controller control.
