Slag-release anti-explosion tube mold for dry-type material tundish working lining of reserved weir plate groove

Abstract

The invention provides a slag-release anti-explosion tube mold for dry-type material tundish working lining of a reserved weir plate groove. The slag-release anti-explosion tube mould structurally comprises a long nozzle, a mold dry type material heat insulation lining, a weir plate reserved mounting groove plate, a slag stopping wall, an impact pad, a working layer, a slag stopping dam, and a shunting and slag release device, wherein the long nozzle is fixedly connected to the bottom end of the left side of the mold dry type material heat insulation lining in an electric welding mode, and theweir plate reserved mounting groove plate is fixedly arranged on the back part of the mold dry type material heat insulation lining. If a part of ports are blocked by slag in the conveying process ofmelting liquid in a tundish die, the external working personnel can be reminded through the bright color of the melting liquid, the direct proportion value of the unfolding amplitude can be adjustedaccording to the size of the pressure value, and then the internal pressure value can be visually judged, so that an shunting interface is pressed and dredged through a single-pressure double-tractionmechanism, the slag on a pressure release mechanism can be offset to an inner material pressing plate for temporary storage, the ports can return to a smooth state, and the occurrence of the tube explosion is reduced.

Description

technical field [0001] The invention belongs to the field of moulds, and more specifically relates to a slag-releasing explosion-proof pipe mold for working lining of a dry material tundish with a weir plate groove reserved. Background technique [0002] After the dry material is melted, it needs to be decompressed through the tundish mold to slow down the impact of the melt on the solidified shell of the crystallizer, and through the tundish mold, it can be shunted through multiple nozzles, so that the flow rate can be controlled while reducing the impact, and It can block most of the residues inside the melt. [0003] Based on the above description, the present inventors found that the existing slag-releasing explosion-proof pipe mold for dry-type material tundish working lining with reserved weir plate groove mainly has the following deficiencies, such as: [0004] During the conveying process of the molten liquid inside the tundish mold, because it can block most of the...

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a slag-releasing explosion-proof pipe mold for dry-type material tundish working lining with reserved weir plate grooves, so as to solve the problem of melting liquid inside the existing tundish mold during the transportation process, because it can Block most of the residue inside the melt. In order to ensure the passage rate of the melt, the setting of the baffle in the tundish mold will be higher. After being blocked by multiple baffles, some residue will still enter the passage. Because the direct output of the port is connected with the solidified embryo shell of the crystallizer, when part of the port is blocked by residue, the flow rate of the remaining ports will increase under the state of input equal pressure, and the output pressure will increase. The orifice of the through pipe is small, and it is difficult for the staff to detect it intuitively. It is easy for the other orifices to burst due to the output of high pressure, and the problem is only discovered by the staff.
