Description
Technical Field
The utility model relates to a refractory material continuous casting processing technology field, in particular to immersion nozzle of slag line position reinforcing.
Background
The submerged entry nozzle is a refractory casing for casting installed at the middle bottom and inserted below the molten steel level of a mold in a continuous casting facility. It can prevent molten steel from being oxidized and splashed, and avoid the crystallization protective slag from being involved in the molten steel. The slag line part of the submerged nozzle is the most seriously corroded part, and the materials used by the submerged nozzle in the prior art have poor erosion resistance and molten steel scouring resistance, so that the production requirement of continuous casting steel cannot be met. The utility model provides a submerged nozzle of slag line position reinforcing, it has the thermal shock nature of good molten steel of resistant and the erosion performance of good slag, molten steel of resistant.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome this technical shortcoming that the thermal shock nature of the resistant molten steel of immersion nozzle is poor among the prior art, the erosion nature of resistant slag steel melting is poor and life is short, provide an immersion nozzle of slag line position reinforcing, it has the erosion performance of the thermal shock nature of good resistant molten steel and good resistant slag steel melting, and its life is 2-3 times of current immersion nozzle.
For realizing the purpose of the utility model, the utility model discloses a technical scheme include: the submerged nozzle comprises a bowl part, a body, a lining, a slag line and side holes, wherein the slag line is made of a high-carbon material with erosion resistance and scouring resistance, and the length of the slag line is 1/5-1/4 of the length of the whole submerged nozzle.
Furthermore, the lateral opening that immersion nozzle was equipped with has 5.
Further, the lining is made of a heat insulation material.
Further, the size of the top opening of the bowl part is 2.5-2.7 times of the size of the bottom opening.
Compared with the prior art, the utility model has the advantages that: adopt the resistant high carbon material that erodees of anti erosion through the slag line position, strengthened the resistant performance that erodees of anti erosion of the long mouth of a river of immersion, the top opening size that is equipped with side opening and bowl portion at the afterbody of immersion nozzle is greater than bottom opening size, has slowed down the velocity of flow of molten steel, has improved the life of immersion nozzle, has improved production efficiency.
