Description
Technical Field
The invention relates to the technical field of continuous casting, in particular to a nozzle for continuous casting.
Background
The general continuous casting process is as follows: pouring molten steel contained in a ladle into a tundish, continuously pouring the molten steel poured into a casting mould, cooling the molten steel once, and spraying cooling water on the surface of the casting blank cooled once to perform secondary cooling, thereby solidifying the molten steel to manufacture the casting blank. In this case, during the process of supplying the molten steel contained in the tundish into the mold, the tapping of the molten steel is controlled by a gate or stopper provided at the tapping hole of the tundish, and the molten steel is supplied into the mold through the submerged nozzle. Alumina (Al 2O 3) inclusions are present in the molten steel, and fine inclusions which have not been removed by the floating separation adhere to the inner wall of the dipping nozzle connecting the tundish and the mold, and cause clogging of the dipping nozzle. In order to solve this problem, there have been conventionally proposed methods such as: a method in which Ar gas is supplied to the inner wall of the immersion nozzle, and the inclusion is trapped (trapping) by bubbles, thereby suppressing the adhesion of the inclusion to the inner wall of the immersion nozzle; and a method of forming a CaO-containing material layer on the inner wall of the immersion nozzle to form alumina and a low-melting point material, thereby removing the adhering inclusions. Although the method using Ar gas can reduce the adhesion of inclusions to the inner wall of the immersion nozzle to some extent, it has a limitation in suppressing the adhesion of inclusions due to the cooling effect or the like caused by Ar gas. Further, a method of forming a CaO-containing substance layer in the inner cavity portion is considered as one of the most effective methods of suppressing adhesion of inclusions to the inner wall of the impregnation nozzle. Further, if the molten steel is directly contacted with 1550 ℃ at normal temperature, the immersion nozzle may be cracked or the like due to instantaneous expansion caused by thermal shock, and thus the immersion nozzle is preheated at 800 to 1100 ℃, in which case the phase transition is accelerated and the possibility of occurrence of failure becomes high.

The sealing surface material of the current ball valve is widely used with plastics and good sealing property, is widely used in a vacuum system, is convenient to operate, is rapid to open and close, is convenient to maintain in a long distance from full open to full close as long as the ball valve rotates by 90 degrees, is simple in structure, is generally movable in sealing ring, is detached and replaced, and can not cause corrosion of the sealing surface of the valve when the ball body and the sealing surface of the valve seat are isolated from a medium in full open or full close, and the application range is wide.
S4: later when rivers pass through fixed pipe 1, the staff rotates through rotating shower nozzle 3, and shower nozzle 3 drives inside solid fixed ring 4 and rotates, and gu fixed ring 4 drives connecting rod 6 and rotates, and connecting rod 6 drives the regulating plate 7 of connecting rod 6 one end and rotate for the water yield size of shower nozzle 3 is controlled to the round hole of difference on the regulating plate 7, thereby avoids the waste of water resource.
S5: the staff pulls spacing post 32 for spacing post 32 drives spring 33 and compresses, when the staff laminates A snap ring 11 and B snap ring 15, afterwards rotate A snap ring 11 and make A buckle 13 on the A snap ring 11 and B fixture block 16 on the B snap ring 15 carry out the joint, thereby make A snap ring 11 and B snap ring 15 laminate fixedly, afterwards when making A snap ring 11 and B snap ring 15 laminate fixedly, the staff unclamps spring 33, the effort of spring 33 compression, make spacing post 32 carry out the forward movement, thereby make spacing post 32 remove to the inside of B snap ring 15 circular hole, thereby make spacing post 32 fix A snap ring 11 and B snap ring 15, thereby avoid the condition of rotation A snap ring 11 and B snap ring 15 between the staff's is unintentional.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
