Problems solved by technology
[0005] In order to make up for the deficiencies of the prior art, in the prior art, the circular cleaning equipment for the tapping hole cannot be applied to the wedge-shaped tapping hole, thus resulting in a wedge-shaped electric arc furnace When replacing the tapping hole, the steel slag on the outside is difficult to remove quickly. The invention proposes a cleaning device for the tapping hole of an electric arc furnace.

The invention discloses an electric arc furnace tapping hole cleaning device which comprises a tapping groove base, an adjusting mechanism and a purging mechanism, wherein the adjusting mechanism is arranged in the tapping groove base, and the purging mechanism is arranged in the adjusting mechanism; and the purging mechanism is composed of a fixing plate, a compressed air tank, an air pipe, an air control valve, a communicating pipe, a purging pipe and a purging pipe head. Air in the compressed air tank is conveyed into the purging pipe through the air control valve by utilizing the air pipe, and cooled steel slag in the tapping groove base is purged by utilizing the purging pipe, so that the cooled steel slag around the tapping groove base can be quickly cleaned, the maintenance time is saved, and the steelmaking efficiency is further improved; and through a clamping block arranged on the communicating pipe and a first sliding groove and a second sliding groove correspondingly formed in the inner wall of the purging pipe, the fit length between the communicating pipe and the purging pipe can be adjusted, so that the device adapts to tapping groove bases with different depths, and the purging effect is better in practical application.
Description
technical field [0001] The invention relates to the technical field of the metallurgical industry, in particular to an electric arc furnace tapping hole cleaning device. Background technique [0002] With the development of the national economy, large-scale construction models have been launched across the country, and under the large-scale construction model, the use of steel has risen sharply. [0003] At present, the domestic demand for steel is relatively large, and the main domestic steelmaking device is the electric arc furnace, which uses the high temperature generated by the electrode arc to smelt ores and metals, which can effectively remove impurities such as sulfur and phosphorus, and the furnace temperature is easy to control. The equipment occupies a small area, so it has strong competitiveness in domestic steelmaking industrial equipment. [0004] When replacing the tapping hole in the electric arc furnace, there is a lot of cooling steel slag outside the orig...
