Technical field
The present invention relates to field of metallurgy, a kind of novel heat-insulation baffle plate particularly, it is a refining unit outside a kind of RH of being applied to stove.
Background technology
Thermal baffle in RH is to be installed on vacuum tank, and its effect is to open when needs are reinforced to vacuum tank, after reinforced end, closes, and prevents high-temperature gas radiation and convection current, causes the damage to associated machines, can reduce the temperature drop of vacuum tank simultaneously.
At present, in the structure of known thermal baffle, its sealing baffle adopts steel plate, and is fixedly welded on axle, under the effect of cylinder, sways, and opens or closes feed opening.The temperature of vacuum tank is more than 1200 ℃, and when sealing plate is closed, the thermal radiation in vacuum tank raises sealing plate temperature, and surface color is rubescent, easily makes the distortion of baffle plate and rotating shaft, occurs jam when opening and closing thermal baffle.When blanking, metallic particles is beaten the baffle surface in high temperature deliquescing, is easy to just cause wearing and tearing, makes the lost of life of baffle plate simultaneously.
Summary of the invention
The object of this invention is to provide a kind of novel heat-insulation baffle plate, adopt water cooling, the temperature of sealing plate and rotating shaft is reduced greatly, guarantee the strength and stiffness of baffle plate and rotating shaft, extend its work-ing life.
The present invention solves the technical scheme that its technical problem adopts: a kind of novel heat-insulation baffle plate, is characterized in that: rotating shaft is arranged on baffles body, is symmetrically arranged with up and down two permanent sleeves in rotating shaft, and permanent sleeve is fixed by holding screw; Sealing plate one side is fixedly welded on two permanent sleeves, and water-cooled tube is fixed on sealing plate; Rotating shaft is hollow structure, and centre separates by solid layer, at inner upper cavity and the lower chamber of forming of rotating shaft; Upper cavity and lower chamber near the position of solid layer radially homonymy be respectively arranged with ⅠHe hole, hole II; Upper cavity top is communicated with entrance of cooling water, and upper cavity lower end is communicated with the water-in of water-cooled tube by hole I; Lower chamber upper end is communicated with the water outlet of water-cooled tube by hole II, and lower chamber bottom is communicated with the outlet of water coolant.
Described water-cooled tube be fixedly connected on sealing plate on lower surface.
Described rotating shaft and sealing plate are all positioned at baffles body below.
Described sealing plate is corresponding with baffles body feed opening.
The method of cooling of this thermal baffle is: water coolant is the lower chamber of the upper cavity by rotating shaft, water-cooled tube, rotating shaft successively, and sealing plate is carried out cooling by water-cooled tube.
The beneficial effect of the invention is: thermal baffle of the present invention, by water cooling rotating shaft and sealing plate, reduces its temperature greatly, reduce sealing plate distortion, extend the life-span of sealing plate and rotating shaft.
