Abstract
The utility model discloses a sliding water faucet compressing device by using weight droppers, which is especially used for continuously casting tundishes in metallurgy and steel production and aims to solve problems caused by that because of the fluctuation of temperature and ambient temperature, a spring compressing device causes the variation of resilience force. The utility model is characterized in that the pressure of the sliding seal of a water draining port is the push force and the pressure formed by gravity through a force arm rather than conventionally acting resilience force of a spring. The utility model has the advantages that pressure is free from the influence of temperature variation, and the force intensity is constant according to the ratio of the weight of a weight dropper and the length of a force arm. Friction resistance can be greatly reduced because no slide way is arranged.

The advantage of this structure is more simple in structure than scheme two, because there is not slideway, displacement is changed mouth of a river frictional resistance little 1/3 and is fit to the use of middle-size and small-size steel mill, it also has a not enough place, because can not changing, filling pipe end can not utilize the flow of the decentraction dislocation control molten steel at the mouth of a river up and down exactly, if control flow, the replacing mouth of a river device of filling pipe end, sliding panel, following mouth of a river three-decker must be arranged.
Technical scheme four: the fulcrum place of the arm of force (6) and the arm of force (16) all is provided with on the hook ball journal (14) that opening is suspended on and substrate (4) is connected to one, two arm of forces are connected with gravity drop hammer H hook with mouth of a river seat F and slip panel seat (15) and are connected as a single entity respectively up and down, and mouth of a river seat and slip panel seat are divided into left side seat and right seat.Its shape symmetry, be installed in when promoting the arm of force the following mouth of a river (5) in the seat of the mouth of a river and sliding panel (12) with ball journal (14) be center of circle rotational slide displacement can about seat change mutually, the top of adopting mouth of a river Q submersed nozzle under the immersion when adopting casting slab in the mouth of a river (5) under the milk-globule shape during casting square billet is that hemispherical plane process polishes and processes and inlay ZrO in the aperture
2Or the inner core ON of nitrogen oxide materials such as ZrC, ZrN, CaO.
The advantage of technique scheme is that the little but also continuous casting that the flexible and changeable square billet that is suitable for casting is fit to the very suitable middle-size and small-size steel mill of casting slab again of not only required motive force uses.
