Abstract
The utility model discloses a fire-resistant water gap used for steelmaking, which comprises a water gap body, wherein a liquid steel inlet and a liquid steel outlet are arranged on the water gap body, and an additional lining is arranged on the inner wall of the water gap body. As the additional lining is arranged on the inner wall of the water gap body, the direct contact between high-temperature liquid steel and the water gap body is avoided, and the additional lining intuitively plays a role of protecting the water gap body, so as to prolong the service life of the water gap. When the fire-resistant water gap is used in a steel mill, in spite of the high-temperature bake or the repeated maximum change of the temperature of the liquid steel, the lining in the inner wall of the water gap realizes the functions of regulating the temperature difference and protecting the outer wall of the water gap, thereby effectively avoiding the rupture of the water gap and ensuring the normal operation of the production in a steel enterprise.
Description
Technical field
The invention belongs to technical field of refractory materials, be specifically related to a kind of steel-making refractory nozzle.
Background technology
Refractory material is the basic material for the hot industry service.In numerous hot industries, steel and iron industry is the most important usefulness of refractory material, and the use amount of refractory material in steel and iron industry accounts for 65%～70% of total amount.Steel and iron industry plays a leading role in the technical development of refractory industry to the demand of kind, quality and the quantity of refractory material.Submersed nozzle in the past, long nozzle, do not add liner, because of passing through the liquid steel temperature height, cast starts from molten steel contact, and storehouse, mouth of a river internal surface temperature moment rises to liquid steel temperature, and outer surface contacts temperature than low many of internal surface temperature with atmosphere, can produce very big thermal stress at mouth of a river material internal, expanding appears in the mouth of a river, and thermal stress makes the mouth of a river grow now to indulge and bursts phenomenon, and accident constantly takes place.Because the goods pore is low, the high hot poor seismic behavior of density will cause goods to burst in the bake process before steel mill uses.In use, particularly one heat steel because bigger temperature contrast, the poor slightly or mouth of a river baking of quality of item bad will appearance bursts or ruptures in first time steel pouring process.Occur slightly bursting and to cause molten steel outside seepage from the parietal suture of the mouth of a river, will cause that molten steel is excessive to be caused device damage even also can bring disaster to site operation personnel's life if severe bursts or ruptures.
The utility model content
The utility model provides a kind of steel-making refractory nozzle safe in utilization, long-life.
A kind of steel-making refractory nozzle comprises mouth of a river body, on the body of the described mouth of a river molten steel import and molten steel outlet is set, and on the inwall of the described mouth of a river body supplemental inner is set.
Because the utility model is provided with supplemental inner on the inwall of mouth of a river body, avoided high-temperature molten steel directly to contact with mouth of a river body, supplemental inner has played the effect of protection mouth of a river body very intuitively, has improved the service life at the mouth of a river.In steel mill uses; no matter be that high-temperature baking or liquid steel temperature greatly change repeatedly; liner in the inwall of the mouth of a river has been given play to fabulous temperature difference adjusting and protection mouth of a river outer wall effect, has effectively prevented bursting of the mouth of a river, has guaranteed normally carrying out of iron and steel enterprise's production.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1: a kind of steel-making refractory nozzle, comprise mouth of a river body 1, molten steel import 2 and molten steel outlet 3 are set on the described mouth of a river body 1, on the inwall of described mouth of a river body 1 supplemental inner 4 is set.
Because the utility model is provided with supplemental inner 4 on the inwall of mouth of a river body 1, avoided high-temperature molten steel directly to contact with mouth of a river body, supplemental inner has played the effect of protection mouth of a river body very intuitively, has improved the service life at the mouth of a river.In steel mill uses; no matter be that high-temperature baking or liquid steel temperature greatly change repeatedly; liner in the inwall of the mouth of a river has been given play to fabulous temperature difference adjusting and protection mouth of a river outer wall effect, has effectively prevented bursting of the mouth of a river, has guaranteed normally carrying out of iron and steel enterprise's production.
Claims (1)
1. a steel-making refractory nozzle comprises mouth of a river body, on the body of the described mouth of a river molten steel import and molten steel outlet is set, and it is characterized in that: on the inwall of the described mouth of a river body supplemental inner is set.
