Abstract
The utility model belongs to the corollary apparatus of continuous small-billet casting tundish sizing placingJi Shu, the stifled stream hammer of particularly a kind of continuous casting metering nozzle, including continuous casting metering nozzle, the lower end of direct rod shape handle it is affixed steel ball, refractory masses in the surface attachment of steel ball, the steel ball of attachment refractory masses is engaged with the circular conical surface of continuous casting metering nozzle horn mouth bottom, and wherein the length of direct rod shape handle is 2.5 3m.The utility model is rational in infrastructure, simple to operate, can improve the stifled stream success rate of metering nozzle, improves the service life of continuous casting metering nozzle, can reduce the labor intensity of worker, the scald phenomenon of personnel when keeping away burning-free oxygen, improve processing safety.
Description
Technical field
The utility model belongs to the corollary apparatus of continuous small-billet casting tundish sizing placingJi Shu, and particularly a kind of continuous casting is determined
The stifled stream hammer in the footpath mouth of a river.
Background technology
Continuous small-billet casting sizing placingJi Shu is a new technology, is not need stopper but rely on mouth of a river internal diameter control note
Enter the pouring procedure of the molten steel flow of crystallizer.This method advantage is：Stopper and stopper control mechanism are not needed, is reduced resistance to
Material expense and equipment and spare part expense, and the control of metering nozzle flow is relatively stable, is advantageous to the raising of continuous casting billet quality.Together
When, it is possible to achieve automatic casting, reduce worker's labor intensity.
Metering nozzle is used for continuous small-billet casting tundish without stopper running gate system, is control crystallizer molten steel flow, stably
The functional refractory of casting speed.
Metering nozzle, which casts in stop pouring process, has certain defect, and due to prolonged casting, molten steel is in metering nozzle
Wall washes away, and makes mouth of a river inwall irregular, therefore the situation that can not block up stream often occurs, production accident is caused when serious, easily
The worker of stifled stream operation is scalded, man power and material's consumption is larger, potential safety hazard be present.Traditional metering nozzle blocks up stream method and deposited
Subject matter it is as follows：
1st, because prolonged casting, molten steel wash away to metering nozzle inwall, make mouth of a river inwall irregular, therefore often
There is the situation that can not block up stream.
2nd, block up stream process and security risk be present, easily scald the worker of operation.
3rd, it is relatively low to block up stream success rate, influences continuous casting and causes to produce.
Utility model content
The purpose of this utility model is that providing a kind of stifled stream of continuous casting metering nozzle hammers into shape, and its is rational in infrastructure, simple to operate, can
To improve the stifled stream success rate of metering nozzle, the service life of continuous casting metering nozzle is improved, the labor intensity of worker can be reduced, kept away
The scald phenomenon of personnel during burning-free oxygen, improve processing safety.
What the purpose of this utility model was realized in：A kind of stifled stream hammer of continuous casting metering nozzle, including continuous casting metering nozzle,
The lower end of direct rod shape handle it is affixed steel ball, refractory masses in the surface attachment of steel ball, adhere to the steel of refractory masses
Ball is engaged with the circular conical surface of continuous casting metering nozzle horn mouth bottom, and wherein the length of direct rod shape handle is 2.5-3m.
Main improvement content is as follows：
1, this new design is to block up stream method for continuous casting metering nozzle, and a stock, steel ball surface are welded on a steel ball
Smear refractory material.
Main improvement effect：
（1）Stifled stream hammer is inserted water gap bowl portion by stifled stream process from the centre side of wrapping, simple to operate.
（2）Oxygen need not be burnt, reduces the damage to mouth of a river endoporus when burning oxygen, service life improves.
（3）The labor intensity of worker is effectively reduced, greatly improves the working environment of workers.
（4）The scald phenomenon of personnel when burning oxygen is avoided, processing safety improves.
The utility model is rational in infrastructure, simple to operate, improves the stifled stream success rate of metering nozzle, improves continuous casting sizing water
The service life of mouth, the labor intensity of worker is reduced, avoid the scald phenomenon of personnel when burning oxygen, improve safe operation
Property.
Brief description of the drawings
The utility model is further described below in conjunction with accompanying drawing, Fig. 1 illustrates for the utility model front view structure
Figure.
Embodiment
