Technical Field

The utility model relates to a metallurgical auxiliary assembly technical field specifically is a metal smelting deslagging device.

Background

With the development of metallurgical technology and the intense competition of the market, the method for reducing the smelting cost of the converter and improving the quality of the molten steel produced by the converter becomes a means for improving the competitiveness of a steel mill. In recent years, the domestic converter smelting process is gradually refined, and the single-slag and double-slag smelting is gradually refined into a single-slag, double-slag, duplex and multifunctional steelmaking method and the like. The dephosphorization period and the decarburization period are generally divided for the double-slag and multifunctional steelmaking method, the slag-dephosphorization slag is required to be poured out after the dephosphorization period is finished, the main characteristics of the dephosphorization slag are high phosphorus content in the slag and high sio2 content in the slag, the removal of a large amount of the dephosphorization slag is beneficial to reducing the phosphorus content in the furnace, the alkalinity of the slag in the decarburization period can be improved, the dephosphorization effect is improved, and the consumption of white lime and steel materials can be reduced for steel types with general phosphorus content requirements.

The deslagging method adopted at the end of the dephosphorization period is to pour slag by reversing the furnace after blowing in the converter dephosphorization period, about 30-40% of slag can be removed by pouring the slag, but the slag in the furnace can not be poured out continuously after the slag pouring amount reaches a certain proportion, and the phenomenon of pouring out molten iron is easy to occur if the slag pouring is continued. In order to further reduce the dephosphorization slag in the converter, a slag removing machine for the converter is developed, and the aim is to continuously improve the slag removing effect on the basis of converter deslagging and prevent molten iron in the converter from being poured out through mechanical slag removing.

The common slag raking machine is a molten iron desulphurization station slag raking machine and a ladle slag raking machine, and the liquid level is enabled to be flush with the edge of an opening under a certain inclination angle for slag raking.

The defects of the technology are as follows:

1. when the slag is removed, some molten steel can be removed out of the steel ladle together with the steel slag, so that the loss of the molten steel is caused;

2. slag or molten steel after cooling and solidification can be left and accumulated at the edge of the steel ladle, so that the molten steel can not flow out from the edge of the steel ladle when the steel ladle pours the molten steel;

3. when the slag is removed, the ladle needs to be inclined, energy is consumed, and certain danger is caused.
