A device for effectively improving the sand filling effect of ladle

Abstract

The invention discloses a device capable of effectively improving the sand filling effect of a steel ladle and relates to sand filling devices of the steel ladle. The device capable of effectively improving the sand filling effect of the steel ladle can be used for drying ladle filler sand and is capable of improving the sand filling effect and improving the automatic casting rate of the steel ladle. According to the device capable of effectively improving the sand filling effect of the steel ladle, the device is installed on a sand filling platform and enables ladle filler sand in a ladle filler sand bin to be evenly placed into a guiding groove with a certain inclination angle through a sliding bin door, flames generated by the combustion of gas in a multihole gas steel pipe can heat a heating plate to generate heat radiation, the ladle filler sand in the guiding groove is fully and evenly preheated by the heat radiation and water is discharged, the ladle filler sand in the guiding groove is filled into a funnel-shaped conduit evenly and continuously under the dynamic action transmitted by the vibration of a vibration machine after the ladle filler sand is fully and evenly preheated by the heat radiation and water is discharged and then accurately enters the water inlet of the steel ladle, and the sand filling quality and the sand filling effect are improved.

Description

technical field [0001] The invention relates to a ladle sand filling device, which is suitable for drying the drainage sand and improving the sand filling effect so as to increase the automatic pouring rate of the ladle, in particular to a device for effectively improving the sand filling effect of the ladle. Background technique [0002] The steel ladle used for turnover in the metallurgical industry, after hot repair, pour chrome drainage sand into the ladle upper nozzle, and fill the ladle upper nozzle, so that after the ladle slide plate is opened, the drainage sand flows out first, and then the molten steel is injected into the tundish. [0003] At present, the average automatic pouring rate of ladles in domestic iron and steel enterprises is between 97% and 98%. For furnaces that cannot be automatically poured, the quality of open poured molten steel cannot be guaranteed due to secondary oxidation. In the traditional sand filling process, the drainage sand packaging ba...

AI Technical Summary

Problems solved by technology

There are two main problems in the traditional process: 1) Due to the influence of the site space, the distance from the lower opening of the drainage sand conduit to the bottom of the ladle is about 2.3m (taking a 210t ladle as an example), and there is a phenomenon of scattered flow of each bag of drainage sand during the injection process through the conduit (injection The beginning and the end are the most obvious), about 1 / 3 of the drainage sand cannot enter the upper nozzle of the ladle, which makes it difficult to fill the upper nozzle of the ladle. After the material fully absorbs heat, it solidifies and crusts, which makes the ladle unable to be poured automatically; 2) The drainage sand itself contains a certain proportion of moisture, and in addition to absorbing moisture during storage, the part of the drainage sand in contact with the molten steel is prone to hardening, and the drainage is unsuccessful. As a result, the ladle cannot be poured automatically, and the entire bag of drainage sand cannot be fully removed by baking
