Detailed description of the invention
The utility model embodiment discloses a kind of Continuous Casting Rolls, to avoid Continuous Casting Rolls surface uneven and cause heat fatigue to be damaged with internal temperature, and the service life of prolongation Continuous Casting Rolls.
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 and Fig. 2, the structural representation of a kind of Continuous Casting Rolls that Fig. 1 provides for the utility model embodiment, the Continuous Casting Rolls installment state structural representation that Fig. 2 provides for the utility model embodiment.
In a kind of detailed description of the invention, Continuous Casting Rolls provided by the utility model, comprise the running roller 1 that inside is provided with wind pushing hole 2 and pore 3, one end of wind pushing hole 2 is communicated with an end face of running roller 1 and is connected with air blast 4, one end of pore 3 is communicated with wind pushing hole 2, and the other end is communicated to the outside of running roller 1.During Continuous Casting Rolls work, air blast 4 pumping gas enters wind pushing hole 2, and the gas in wind pushing hole 2 is sprayed by pore 3 again, and the gas of ejection takes away the heat of roller surface in diffusion process.
For the ease of gas circulation in running roller 1, wind pushing hole 2 can be arranged along the axis of running roller 1, and one end that now wind pushing hole 2 is communicated to running roller 1 end face is positioned at the center of running roller 1 end face.The other end of wind pushing hole 2 can be communicated to the other end of running roller 1.Certainly, for improving the operating efficiency of the air cooling system that air blast 4, wind pushing hole 2, pore 3 etc. are formed by connecting, wind pushing hole 2 can be set to blind hole, is similarly and is convenient to gas circulation, can be communicated to the other end of running roller 1.Certainly, the position of wind pushing hole 2 is not limited to vertically, also can be set to other directions, and the length of wind pushing hole 2 also can more be arranged according to the working condition of Continuous Casting Rolls.
Continuous Casting Rolls heat fatigue damage reason mainly its in the course of the work surface with internal temperature difference cause thermal stress.Therefore, for better reducing Continuous Casting Rolls 1 surface and inner temperature difference, make the Temperature Distribution of running roller 1 comparatively even, the position of pore 3 can be set to be uniformly distributed.Being uniformly distributed herein mainly refers to that the orifice position that pore 3 is communicated to running roller 1 surface is equally distributed, and its other end all can be communicated with wind pushing hole 2.Thus, the effect of gas to running roller 1 sprayed by pore 3 aperture is relatively uniform, thus makes the surface temperature uniformity of running roller 1.Consider running roller 1 problem that temperature distributing disproportionation is even diametrically because surface causes with internal temperature difference, the position of pore 3 can be set to the radial direction along running roller 1, now for making pore 3 be communicated with wind pushing hole 2, the length of wind pushing hole 2 need be arranged according to the position of pore 3.Certainly, under meeting some special requirement or some working condition, the position of pore 3 and distribution situation also can be arranged according to actual needs.
For improving the air-supply efficiency of air blast 4, the sealing of air cooling system need be improved, air blast 4 can be connected by carrier pipe 5 with wind pushing hole 3.For ensureing sealing effectiveness, one end that wind pushing hole 2 is connected with carrier pipe 5 can be set to the mouth that is threaded, and an end of carrier pipe 5 arranges the swivel joint 6 be tightly connected with the mouth that is threaded.It is pointed out that carrier pipe 5 is not limited to aforesaid way with the connected mode of wind pushing hole 2, also can adopt the mode that is tightly connected of other routines.Certainly, if do not seal, the gas sent into due to air blast 4 also can be sprayed by pore 3 via wind pushing hole 2, does not carry out sealing also can.
Sending into the cleannes of gas for improving air blast 4, screen pack 7 can be set at the air inlet mouth of pipe of air blast 4.Certainly when gas sanitizes degree meets the demands, also screen pack 7 can not be set.
Outside the main cause heat extraction fatigue damage damaged owing to causing Continuous Casting Rolls 1, wearing and tearing are also very important one side.The external diameter caused due to wearing and tearing etc. for reducing running roller 1 reduces thinning degree, delay the Continuous Casting Rolls comdemning period caused thus, the surface of running roller 1 can arrange abrasionproof overlay cladding 8 further, and the hardness of abrasionproof overlay cladding 8 can be set to be greater than 50HRC, and comprises 50HRC.Certainly, the hardness of abrasionproof overlay cladding 8 also can need to arrange according to the different operating of Continuous Casting Rolls.For guaranteeing that the conveying of product on running roller 1 is stablized, running roller 1 can arrange helicla flute 9 further, and the inwall of helicla flute 9 is cambered surface, and namely running roller 1 section outward flange is diametrically continuous print indent camber line.When running roller 1 surface is provided with helicla flute 9, the surface of helicla flute 9 when abrasionproof overlay cladding 8 is set further, should be arranged at.
Based on the Continuous Casting Rolls provided in above-described embodiment, the utility model additionally provides a kind of conticaster, and this conticaster comprises any one Continuous Casting Rolls in above-described embodiment.The mechanism of other each several parts of this conticaster please refer to prior art, repeats no more herein.The Continuous Casting Rolls in above-described embodiment is have employed, so the beneficial effect of this conticaster please refer to above-described embodiment due to this conticaster.
Concrete, the both ends, left and right of running roller 1 when mounted, can be connected in bearing block 10 by above-mentioned Continuous Casting Rolls, and are provided with the bearing 11 of cross-under in running roller about 1 both ends in bearing block 10.Certainly, the connected mode of Continuous Casting Rolls and bearing block 10 is not limited to said method, also can adopt the connected mode of other routines.
In this description, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
