Description

Refractory Carrier of Timing Ladles and Playing Tundish

The present invention is to build a built-in refractory on the inner side of the molten steel ladle (teeming ladle) and continuous casting tundish, the large size formed to discharge the molten steel on the bottom of the ladle or tundish The present invention relates to a refractory conveying device for a teaming ladle and a playing tundish that can be easily transported during construction of a well brick refractory.

In the known steelmaking process, the teams take the molten steel produced by the converter and move it to the continuous casting facility and inject the molten steel directly into the mold. And refractory bonded to the inside (slag line, wall refractory, floor refractory, wellblick), and when the injection of molten steel into the mold is completed, the inner side of the outer plate is bound within a limited time when the refractory is damaged by the hot molten steel. Some of the refractory must be replaced.

In addition, since the slag is greatly influenced by the composition and reaction time of the slag (slag), refractory materials such as mag-carbon material having excellent corrosion resistance are used. Refractory materials such as high alumina, zircon, spinel, and alumina-magnesia are used, and on one side of the bottom refractory, a flow-controlled refractory (well brick) in which molten steel exits into a tundish in a casting process (high corrosion resistance The quality Al₂O₃-MgO-C) is combined.

In addition, as shown in Figure 1, the ladle and tundish, the slag grain 102 and the wall refractory 103 and the bottom refractory 109 are respectively built on the inner surface of the ladle 101, the floor refractory The lower end of the wellbile 104 coupled to one side of the 109 is interposed between a top nozzle 105 installed to be inserted therein and a sliding nozzle plate 106 installed to block and open and close the molten steel at a lower side thereof. The collector nozzle 107 is installed, and the shroud nozzle 108 for preventing the oxidation of molten steel and injecting molten steel with a tundish is connected to the lower side of the collector nozzle 107.

On the other hand, the tundish is installed on one side of the floor refractory refractory for flow control, the refractory is composed of a submerged nozzle (Subentry) for supplying molten steel is immersed in the casting mold.

In addition, the wellblick 104 of the ladle and tundish is installed in a place where molten steel flows out at a high speed so that abrasion and erosion occurs badly due to the hot molten steel, cooling the molten steel in the wellbrick and the main surface after the molten steel injection operation Due to the high adhesion of residues, the cleaning process is carried out by oxygen and dropping occurs.

In addition, the shape of the well 104 is a rectangular column or columnar outer shape, the inner shape of the molten steel is in contact with the central portion is narrow, the upper and lower parts are wide, the molten steel flows easily from the top, The top nozzle 105, which is a refractory for flow rate adjustment, is easily inserted, and the wellbile 104 receives a shock after the injection of molten steel so that the molten steel may be leaked to the lower part of the ladle due to cracking and dropping. The wellblic 104 located deep in the bottom of the tundish is to be replaced using a wire or the like after a predetermined time of molten steel injection.

However, in the construction of the wellbrick as described above, the weight of the wellbrick is not only a heavy load but also a ladle (tondish) 101 when replacing and installing the wellbrick 104 located on the bottom of the ladle and the tundish. Due to the narrow shape of the inner hole, it is difficult to handle the wellblick 104, and the wellblick 104 is difficult to handle due to the carbon-containing material. There have been many problems such as increase in the working time accordingly.

The present invention is to improve the various problems as described above, its purpose is to carry out a safe work by preventing the fall by safely performing by a well-supporting device when replacing and installing a large-size wellbrick It is to provide a refractory conveying device of the teaming ladle and playing tundish to prevent the breakage of the operator and subsequent safety accidents of the worker.
