Description
Technical field
The present invention relates to the metallurgical continuous casting field, specifically a kind of immersion device for clamping water inlet.
Background technology
In continuous casting process, in order to prevent molten steel oxidation, adopt submersed nozzle to carry out totally-enclosed pouring molten steel, to avoid molten steel and air to come in contact, make molten steel directly enter in the crystallizer by submersed nozzle from tundish, thereby the raising steel quality guarantees that continuous casting carries out smoothly, we can say that the result of use of submersed nozzle has directly influenced casting efficiency and slab quality.Submersed nozzle is fixed in the bottom of filling pipe end by immersion device for clamping water inlet, and immersion device for clamping water inlet comprises a spring compression mechanism that submersed nozzle and filling pipe end are closely contacted, to prevent the bleed-out accident.Casting efficiency and production safety have directly been influenced the service life that is to say spring compression mechanism.Because the operating ambient temperature of spring compression mechanism is very high, the elasticity of spring is easy to temperature influence and reduces, and guarantees at present that therefore the technological improvement in spring compression mechanism service life all is the operating ambient temperature that reduces spring as much as possible.As Chinese patent literature CN2560456Y, a kind of tundish slide gate mechanism with the mouth of a river under the quick replacing immersion is disclosed, comprise that an air cooling system reduces the operating ambient temperature of groups of springs with cold wind; Chinese patent literature CN2558484Y and for example discloses a kind of steel ladle sliding water gap mechanism, wherein by heat insulation backplate is set spring compression mechanism and high-temperature region is isolated, to keep relatively low operating ambient temperature.But, high temperature only is to influence a spring aspect in service life, prior art has all been ignored because immersion device for clamping water inlet compresses submersed nozzle and filling pipe end by lever principle, therefore the pressure that the both sides (i.e. a side of close submersed nozzle and away from a side of submersed nozzle) that are sleeved on the spring on the guide post are subjected to gland is uneven, this unbalance stress, make the deformation length difference of these both sides of spring, the easy like this spring integral body that causes deforms, the performance of flexible member is played a role fully, also influence simultaneously the service life of flexible member, it is inevitable stressed uneven more after spring integral body deforms, will cause insufficient pressure between submersed nozzle and the filling pipe end like this, cause the mouth of a river out of control, not only cause device damage easily, security incident more likely takes place.
