Problems solved by technology

[0006] The existing tundish mostly uses the vacuum stopper-type pouring control method, and the stopper core rod uses a lot of refractory material, which is time-consuming and labor-intensive to install the refractory material, and the refractory material needs to be baked together with the tundish, and the refractory material breaks or the stopper rod Bending will affect the normal pouring of molten steel; during the pouring process, it is necessary to manually press the lever of the stopper mechanism for a long time, which is labor-intensive. Due to the high temperature outside the ladle and the occasional splash of steel, it is easy to burn the workers

Embodiment Construction

[0033] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0034] The molten steel pouring device provided by the invention has a structure such as figure 1 As shown, it is composed of ladle 1, ladle sliding nozzle unit 2, tundish 3 and tundish sliding nozzle unit 4. The ladle sliding nozzle unit is fixed on the bottom of the ladle through eyebolt screws. The ladle and the tundish are connected through the ladle sliding nozzle unit, and the tundish slides The nozzle unit is fixed on the bottom of the tundish by screws, and the sliding nozzle unit of the tundish includes a second sliding nozzle mechanism and a driving mechanism.

[0035] The structure of the ladle sliding nozzle unit is as follows figure 2 As shown, it includes a first sliding nozzle mechanism and a long nozzle mechanism installed below the first sliding nozzle mechanism. The first sliding nozzle mechanism includes a sliding frame 21, an upp...

Abstract

The invention provides a molten steel pouring device. The device comprises a steel ladle, a middle ladle, a steel ladle sliding gate nozzle unit fixed at the bottom of the steel ladle and a middle ladle sliding gate nozzle unit fixed at the bottom of the middle ladle. The steel ladle sliding gate nozzle unit comprises a first sliding gate nozzle mechanism and a long gate nozzle mechanism. The middle ladle sliding gate nozzle unit comprises a second sliding gate nozzle mechanism and a drive mechanism. The long gate nozzle mechanism performs reciprocating rectilinear movement in molten steel along with a sliding frame to lead the molten steel into the middle ladle evenly, and accordingly, molten steel splattering can be prevented effectively, secondary oxidation caused by contact of the molten steel with the air is prevented, the molten steel purity is improved, and the casting quality is guaranteed; according to the second sliding gate nozzle mechanism, the molten steel flow is adjusted by adjusting the opening and closing of upper and lower slide brick nozzles, and the molten steel tapping amount is controlled, accordingly, various problems brought by the stopper type pouring control mode of the middle ladle is solved fundamentally, and the seal performance is good; the connection rod and slide movements are stable and accurate; the device is simple in structure, convenient to mount and dismount and good in pouring quality.

Description

technical field [0001] The invention relates to a molten steel pouring device, in particular to a molten steel pouring device composed of a ladle, a ladle sliding nozzle unit, a tundish, and a tundish sliding nozzle unit, and belongs to the technical field of molten steel pouring equipment. Background technique [0002] With the increasing requirements for steel quality, steel mills have developed various ladle refining and pouring technologies, the purpose of which is to purify molten steel and improve the purity of molten steel. The molten steel pouring device is to realize the transition of molten steel from ladle to tundish and tundish Molten steel pouring apparatus into castings. [0003] The ladle sliding nozzle mechanism is installed at the bottom of the ladle. It is a molten steel control device in the process of hydrating multiple ladles and pouring a large casting. It can adjust the flow of molten steel from the ladle to the tundish, and promote the steady flow of ...
