Embodiment
Fig. 1 is one-piece construction schematic diagram of the present utility model (structure that not shown inside is detailed), the internal structure showing furnace roller that Fig. 2 is then detailed.Furnace roller of the present utility model comprises roller 2 and is fixed on the spindle nose 1,6 at roller 2 two ends, furnace roller also comprises the water-cooled core pipe 8 being enclosed within refractory fiber floor 4 outside roller 2, being positioned at roller, the spindle nose of roller 2 side is provided with through hole, the spindle nose of roller opposite side is provided with holding tank, water-cooled core pipe 8 is through the spindle nose being provided with through hole and be inserted in the holding tank of opposite side spindle nose, through hole and leave gap between holding tank and water-cooled core pipe 8, so that water coolant can flow through.Be respectively arranged with fixing block plate 5 and movable block plate 3 at the two ends of refractory fiber floor 4, fixed dam 5 can be fixed on roller 2 by welding process, and shifting board 3 can be fixed on roller 2 by half snap ring 7.
Outside water-cooled core pipe 8, cover has guide pipe 9, and this guide pipe 9 is fixed together by round steel with water-cooled core pipe 8, and can form gap like this between guide pipe 9 and water-cooled core pipe 8, water coolant can from Clearance Flow.Be fixed together by round steel between guide pipe 9 and roller 2, equally, also can form gap between guide pipe roller in September 2 and be convenient to water coolant and flow through.Refractory fiber floor 4 comprises along the spaced multiple circular fibrous magnesium silicate ring plate of roller length direction and stainless steel ring plate, and its preparation method will be described in detail later.
Be provided with multistage round steel 10 between the outer wall of water-cooled core pipe 8 and the inwall of guide pipe 9, and this multistage round steel 10 welds, with enhanced stability with the outer wall of water-cooled core pipe 8 and the inwall of guide pipe 9 respectively.Also be provided with multistage round steel between the outer wall of the through hole of spindle nose and the inwall of holding tank and water-cooled core pipe, and this multistage round steel also welds with the outer wall of water-cooled core pipe 8 and the inwall of through hole and holding tank respectively, further enhanced stability.
See Fig. 2 and Fig. 3, be also provided with multistage round steel between guide pipe 9 outer wall and roller 2 inwall, this multistage round steel, respectively at guide pipe 9 outer wall and the welding of roller 2 inwall, plays reinforcement effect, does not affect water coolant simultaneously and flow through.
The preparation method of refractory fiber floor 4 of the present utility model is as follows: in refractory pebbles cotton fibre, add the material such as a small amount of Zirconium oxide fibre and toughener (toughener is exactly the sticking glue of tool, can bond various solid mixture), be made into sheet; Again the refractory pebbles cotton fibre of sheet through on roller 2, and intert 304 stainless steel substrates in the centre of refractory pebbles cotton fibre sheet, good rear the pressurizing device of string applies pressure at two ends, refractory pebbles cotton fibre sheet and the 304 stainless steel substrates compactings that are mingled with; Roller 2 one end adds fixed gear dish 5, and the other end adds movable block plate 3, and movable block plate 3 can be dismantled, and changes refractory pebbles cotton fibre; After having press-fited, wait for body of roll release stress, namely between fibrous magnesium silicate sheet and sheet, distress resolves is shaped; Finally the asbestos roll press-fited is put on lathe and the outside of fibrous magnesium silicate sheet is lathed disc, form the profile of fibrous magnesium silicate roller.Do not allowed the surface imperfection such as crackle, scratch to exist when noting fibrous magnesium silicate roller surface working, degree of compactness wants high, does not produce sintering, does not fall block within work-ing life through high temperature.Whole refractory pebbles cotton fibre water-cooled furnace roller statical equilibrium requires to be less than 1.2 kilograms, dynamic balance grade G=6.3.
See Fig. 5, cold water enters core pipe 8 from spindle nose one end, flows to the holding tank in the other end of spindle nose, then flows back to from roller 2.
