Abstract
The utility model provides an airtight air-cooling carbon sleeve roller which implements the complete separation of cooling gases and gases in a furnace and is suitable for the working conditions that the component and content requirements of the atmosphere in the furnace are severe, and the cooling gases in a roller core and the atmosphere in the furnace are not allowed to be leaked mutually. The airtight air-cooling carbon sleeve roller comprises a roller core and a carbon sleeve, wherein the carbon sleeve is sleeved outside the roller core; the roller core and the carbon sleeve are connected by a key and a bolt; the roller core is provided with a key slot and a threaded sleeve pipe installation hole; the carbon sleeve is provided with a key slot open pore; the key slot and the threaded sleeve pipe installation hole are arranged on the circumference of the roller core in a crosslinked mode; and the threaded sleeve pipe installation hole of the roller core is internally provided with an airtight threaded sleeve pipe which is used for mounting a bolt and separating the atmosphere in the roller core and the furnace. According to the utility model, the technical limit that the existing air cooling carbon sleeve roller can not implement 100% of airtightness can be remedied, and the airtight-type air cooling carbon sleeve roller is suitable for the working conditions that the component and content requirements of the atmosphere in the furnace are severe, and the cooling gases in the roller core and the atmosphere in the furnace are not allowed to be leaked mutually.
Description
Technical field
The utility model relates to the carbon cover roller that is applied to continuous annealing furnace, is specifically related to a kind of airproof air cooling carbon cover roller that adopts Seal Design.
Background technology
Carbon cover roller is made up of the carbon cover that roller core and cover are connected in its outside, and roller core and carbon cover are two independently parts.In the assembling process, roller core arrives these two unit constructions through special design between the carbon cover.Fig. 1 and Fig. 2 are the mode of connection of present existing two kinds of roller cores and carbon cover.
Fig. 1 is connected with the mode of carbon cover through " key+bolt " for roller core, can be through the mutual seepage in gap of threaded hole with furnace gas in the roller core.Fig. 2 is connected with the mode of carbon cover through " carbon cover set collar+bolt " for roller core, also can be through the mutual seepage in gap of bolt hole with furnace gas in the roller core.
Thereby, use such air cooling carbon cover roller, roller core inside and furnace atmosphere can not realize isolating fully, and the cooling gas in the roller core has trace and leaks into stove inside.For the strict type of furnace of protective atmosphere composition and content requirement in the stove, certain limitation is arranged.
Summary of the invention
The utility model technical problem to be solved is the technical deficiency to above-mentioned existence; A kind of isolation fully that realizes cooling gas and furnace gas is provided; Be applicable to that furnace atmosphere composition and content requirement are strict, do not allow the airproof air cooling carbon cover roller of interior cooling gas of roller core and the mutual seepage of furnace atmosphere.
The utility model solves the technical scheme that its technical problem adopted:
Airproof air cooling carbon cover roller; Include roller core and be sleeved on the outer carbon cover of roller core; Roller core is provided with keyway and threaded sleeve open hole, and the carbon cover is provided with the keyway perforate, uses key to be connected with joint bolt between roller core and the carbon cover; It is characterized in that; Described keyway and threaded sleeve open hole are cross type and are arranged symmetrically on the roller core circumference, and the keyway perforate that carbon puts also is cross type arranges, the threaded sleeve that is provided with airproof in the threaded sleeve open hole of roller core is used for erection bolt and isolates in the roller core and the atmosphere in the stove.
In such scheme, between described threaded sleeve and the roller core pressure-tight weld.
The mode of connection of the utility model roller core and carbon cover is " key+bolt " form; Set up bubble-tight threaded sleeve of welding at the roller core position of opening; This sleeve pipe can be isolated gas in the roller core and furnace gas fully, and formation can be satisfied the airproof air cooling carbon cover roller that resistance to air loss requires.
Compared with present technology the utility model can remedy existing air cooling carbon cover roller and can not realize 100% gastight technical limitation, is applicable to that furnace atmosphere composition and content requirement are strict, does not allow the interior cooling gas of roller core and the operating mode of the mutual seepage of furnace atmosphere.

Fig. 1 is a roller core and the carbon cover structure iron that is connected of the mode through " key+bolt " only
Fig. 2 is that roller core and carbon cover pass through the mode johning knot composition of " carbon cover set collar+bolt "
Fig. 3 is the utility model example structure figure
Fig. 4 is the keyway place enlarged view of the utility model embodiment
Fig. 5 is the A-A direction view of Fig. 4
Among the figure: 1-roller core; 2-carbon cover; 3-joint bolt; 4-key; 5-threaded sleeve
The perforate of 6-roller core keyway; 7-threaded sleeve open hole; The perforate of 8-carbon cover keyway.
Embodiment
Below in conjunction with embodiment, the utility model is further described:
Like Fig. 3, Fig. 4 and Fig. 5 airproof air cooling carbon cover roller; Include and comprise roller core 1 and be sleeved on the carbon cover 2 outside the roller core 1; Roller core 1 is provided with keyway perforate 6 and threaded sleeve open hole 7, and carbon cover 2 is provided with carbon cover keyway perforate 8, and use key 4 is connected with joint bolt 3 between roller core 1 and the carbon cover 2; Wherein said keyway is cross type and is arranged symmetrically on roller core 1 circumference, and the threaded sleeve 5 that is provided with airproof in the threaded sleeve open hole 7 of roller core is used to install joint bolt 3.
In the present embodiment, be pressure-tight weld between described threaded sleeve 5 and the roller core 1.
During installation, earlier threaded sleeve 5 (4) is welded on the threaded sleeve open hole 7 of roller core 1, welding process is a pressure-tight weld; Again carbon cover 2 is socketed on the roller core 1, adjust the position after, key 4 is inserted in the keyway of roller cores 1 and carbon cover 2; At last joint bolt 3 is screwed in the threaded sleeve 5, accomplishes the installation of airproof carbon cover roller.
Claims (2)
1. airproof air cooling carbon overlaps roller; Include roller core and be sleeved on the outer carbon cover of roller core; Roller core is provided with keyway and threaded sleeve open hole, and the carbon cover is provided with the keyway perforate, uses key to be connected with bolt between roller core and the carbon cover; It is characterized in that: described keyway and threaded sleeve open hole are cross type and are arranged on the roller core circumference, are provided with in the threaded sleeve open hole of roller core to be used for erection bolt and to isolate in the roller core and the threaded sleeve of the airproof of the atmosphere in the stove.
