Characteristics of the present invention are:
The present invention uses the inner surface spraying one deck spray paint of spraying device special at slag ladle, after this layer spray paint can guarantee that slag enters slag ladle after slag ladle is poured out slag, not with slag ladle inner surface bonding, reach the purpose of quick deslagging, this process structure is reasonable, safe and reliable, easy and simple to handle.The spraying device special that is used for online automatic slag tank spraying process adopts the mode of camber line shape multi-angle spraying, makes the coating at each position of inner surface that is sprayed on slag ladle meet the requirements of thickness, has realized on-line spray.
The present invention has shortened the deslagging time of slag ladle, has reduced cost, has improved productivity ratio, has prolonged the service life of slag ladle.
Description of drawings
Fig. 1 is the structural representation of online automatic slag tank spraying device of the present invention.
The specific embodiment
Further specify the specific embodiment of the present invention below in conjunction with given embodiment.
A kind of online automatic slag tank spraying process of the present invention is characterized in that the inner surface spraying one deck spray paint at slag ladle, and its step is as follows:
When (1) the slag ladle internal surface temperature after discharging slag is 100-600 ℃, use spraying automatically
Equipment sprays one deck spray paint at the inner surface of this slag ladle,
(2) spray paint of described slag ladle inner surface rapid draing in the process that slag ladle transports,
Described spray paint is the water soluble mixt of fine granularity refractory material, and the percentage by weight of its each component is silica 1 5-25%, alundum (Al 20-35%, and carbon 5-10%, all the other are water.
The thickness of described spray paint is 0.5-5mm.
This technology also can be at normal temperatures, to the spraying of the slag ladle inner surface behind deslagging one deck spray paint, after spraying is finished, need be placed into the spray paint drying after, slag ladle just can come into operation.
As shown in Figure 1, a kind of device that is used for the described online automatic slag tank spraying process of claim 1, comprise hydraulic system 3, coating dynamic transfer system 5, control device 2 and shower nozzle 14, it is characterized in that comprising motor bracket 6, the hydraulic motor 7 that is located on this motor bracket 6 and is connected with described hydraulic system 3 by pipeline 4, one end is the square truss 8 that is rotatably connected of hydraulic motor 7 therewith, the jointed shaft 12 that is connected of the other end of square truss 8 therewith, the tumbler 13 that is connected of jointed shaft 12 therewith, be located at the hinged-support 9 at described square truss 8 middle parts, the hydraulic oil pipeline 11 that one end is connected with described hydraulic system 3, the coating pipeline 10 that one end is connected with described coating dynamic transfer system 5, be located near the velocity sensor 1 the slag ladle transport vehicle 16, this velocity sensor 1 is connected with described control device 2, this control device 2 is connected with described coating dynamic transfer system 5, the other end of described hydraulic oil pipeline 11 passes described hinged-support 9 and is connected with described tumbler 13, this tumbler 13 is connected with described shower nozzle 14, and the other end of described coating pipeline 10 passes described hinged-support 9 and is connected with described shower nozzle 14.
