Problems solved by technology

[0002] The dip tube of RH refining furnace is an important equipment for vacuum treatment of molten steel. Due to continuous work in molten steel, its refractory material layer is corroded by molten steel for a long time, causing damage and falling off. If it is not repaired in time, the dip tube will soon be scrapped and given Steel mills cause losses and increase steelmaking costs
The gunning machine of the previous technology has problems such as low gunning quality and difficult operation

Abstract

The invention belongs to the metallurgical furnace mending machinery field, in particular to a gunning machine for a submerged tube of a RH refining furnace, which is provided with a single gun structure and applicable to process an operation of hot-state gunning refractory material. The invention is consisted of a framework device, a spray gun swiveling device, a spray gun self-running device, an accessory system and a walking trolley. The invention comprises a beam, an upright column, a guideway, a slipper block, a peristyle connecting disk, a rotary decelerating motor, a small toothing fluted disc, a big toothing fluted disc, a limit switch, a straight through type rotary joint, a gunning charging bucket, a constant pressure water supply system, and an automated electric control system. The invention is characterized in that: adopting the straight through type rotary joint; no wrapping when gunning a charge pipe and a water pipe; flexible operation for the gun which can line feed up and down, and also can rotate freely for 360 degree, and can process a separate local point-to-point operation; processing with wireless remote control; a high quality mending; and high efficiency. The gunning machine needn't to be washed in routine use and has a small workload for maintaining and mending.

Description

technical field [0001] The invention belongs to the field of on-line repairing machinery for metallurgical furnaces and kilns, in particular to a RH refining furnace dip tube gunning machine with a single spray gun structure. This gunning machine is suitable for on-line thermal gunning of refractory materials on the dipping tube of the RH refining furnace, repairing the area of ​​the dipping tube corroded by molten steel, and prolonging the life of the dipping tube. Background technique [0002] The dip tube of RH refining furnace is an important equipment for vacuum treatment of molten steel. Due to continuous work in molten steel, its refractory material layer is corroded by molten steel for a long time, causing damage and falling off. If it is not repaired in time, the dip tube will soon be scrapped and given Steel mills cause losses and increase steelmaking costs. The gunning machines of the prior art have problems such as low gunning quality and difficult operation. ...
