Description

The four-wheel-type continuous casting machine

The utility model relates to the continuous casting and rolling casting machine, and a kind of continuous casting machine is particularly suitable for as producing the casting machine of aldray electrician with pole stock.

The casting machine of existing continuous casting and rolling generally all is a two-wheeled, 22 the drift angles about spending of having an appointment after the structure of this two-wheeled has been picked ingot casting, and the existence one of drift angle is easily to produce micro-crack, ingot quality is not high; The 2nd, ingot casting has lateral pressure and friction to crystallizing wheel, shortens the crystallizing wheel life-span, the long ingot quality that also influences of time one.In addition, existing crystallizing wheel is generally Y type, M type, has only three coolings, and inhomogeneous cooling is even, and it is thick to make the ingot casting core occur crystal grain easily, and tissue looseness forms shrinkage porosite or shrinkage cavity phenomenon, and is bigger to the quality influence of ingot casting.

The purpose of this utility model is in order to overcome above-mentioned the deficiencies in the prior art, to propose a kind of ingot casting and picked no drift angle, the better four-wheel-type continuous casting machine of ingot quality.

Realize the technical scheme of above-mentioned purpose: the four-wheel-type continuous casting machine mainly by crystallizing wheel, water pot, access bridge, contact roller, regulating wheel, directive wheel, ring steel belt, cooling device, pick the ingot device and base is formed, crystallizing wheel is by motor-driven, access bridge places the top of picking the ingot device, the pouring mouth that waters pot is between crystallizing wheel and contact roller interface, ring steel belt is successively through returning crystallizing wheel behind crystallizing wheel, contact roller, regulating wheel and the directive wheel, and the ingot device that picks that is fixed on the base by support picks head and inserts in the crystallizing wheel grooved and be close to bottom land.

The cross section of crystallizing wheel is the H type, the inboard of H type crystallizing wheel, outside then be equipped with cooling device with the left and right sides.

The nozzle of cooling device is the sphere nozzle.

The cooling device of the crystallizing wheel outside and the left and right sides is a removable frame.

The rotating shaft of regulating wheel is contained in an end of swing arm, and the other end of swing arm connects the piston of cylinder, and swing arm middle part hinge is in the side of base, and cylinder is by base support.

Adopt the beneficial effect of technique scheme: at first, from structure guaranteed crystallizing wheel, contact roller, regulating wheel and this four wheels of directive wheel central plane, pick that the ingot device picks head, the access bridge central plane is all in same plane, alloy liquid flows in the crystallization race by watering pot pouring mouth, crystallizing wheel turns over 180 degree back aluminum alloy melts has approximately become alloy cast ingot, after having picked, enter in the access bridge groove and flow into next procedure, any drift angle does not appear in whole process ingot casting, both improve the quality of ingot casting, prolonged the life-span of crystallizing wheel again; Secondly, adopt novel H type crystallizing wheel and cooling device is installed, realize the four sides cooling, can obtain the uniform ingot casting of structure refinement in inboard, the outside and the left and right sides of H type crystallizing wheel; In addition, cooling device of the present utility model adopts the sphere nozzle, and the water liquid that has changed the ejection of duck-beak type or straight hole formula nozzle is inhomogeneous, and jet face is wide inadequately, can't eliminate defectives such as crystallizing wheel surface hotting mask, has improved cooling condition, has further improved ingot quality.

Below in conjunction with accompanying drawing in detail the utility model is described in detail:
