Abstract
The invention discloses a roller way for a steel tube reheating furnace. The roller way comprises a roller body, a first cover plate, a second cover plate, a roller shaft and a water pipe, wherein the first cover plate and the second cover plate are fixedly connected with two ends of the roller body; the matched roller shaft is arranged in the center of the roller body; the roller shaft and the roller body are matched with each other to form an inner cavity; a through hole is formed in the roller shaft; the water pipe is fixedly connected to the through hole; the roller shaft extends to the end part of the roller body; a plurality of small holes are formed in the roller shaft; the inner cavity is communicated with the through hole through the small holes. According to the roller way for the steel tube reheating furnace, the roller shaft extends to the end part of the roller body so as to improve the supporting action on the stress position of the roller body and to prevent breaking of the roller body; meanwhile, cooling water enters the inner wall of the roller body to directly cool the roller body, so that the hardness of the roller body cannot be reduced due to over-high temperature, and formation of pits in the surface of the steel tube caused by adhesion of the roller body to the steel tube is avoided.
Description
Technical field
The present invention relates to a kind of roller-way, relate in particular to a kind of for the roller-way in the steel pipe reheating furnace stove.
Background technology
Before the rolling steel pipe of pilger mill is advancing sizing mill, need carry out reheat, also need to carry out reheat if heat-treat, the steel pipe reheat adopts walking-beam furnace mostly, and the turnover stove of steel pipe adopts roller-way to carry.Roller-way is the major equipment that mill transports rolled piece, and its weight accounts for about 40% of whole mill gross weight of equipment amount, is maximum equipment that uses in the mill.
The structure of the roller-way that is used for the steel pipe reheating furnace of prior art mainly comprises 1 roll body, roll shaft 4 and water pipe etc. 5 as shown in Figure 1, and wherein roll shaft 4 cooperations are installed in the roll body 1, and have constituted inner chamber 6, and water pipe 5 is arranged in roll shaft 4.Because the material of roll body is high temperature steel and as seen from the figure, water coolant wherein only plays the effect of cooling roll shaft, the pair of rollers outside surface does not play cooling effect substantially, temperature is very nearly the same in roll body surface temperature and the stove, furnace roller has in use been found some problems like this, at first is the roll body hot soak condition, insufficient strength, very easily in neck line place fracture, distortion, its in single stove year consumption reach 50-60 spare; Secondly roll body surface at high temperature and hardness reduces for a long time sticks together with the high-temperature steel tube of carrying thus, makes the body surface form pit one by one, has improved production cost, has reduced production efficiency.
Summary of the invention
Technical problem at above-mentioned existence the objective of the invention is: proposed a kind of Stability Analysis of Structures, the roller-way structure that long service life and production efficiency are high.
Technical solution of the present invention is achieved in that a kind of steel pipe reheating furnace roller-way, comprises roll body, first cover plate, second cover plate, roll shaft and water pipe; Described roll body two ends are fixedly connected with first cover plate and second cover plate respectively; Described roll body center is provided with supporting roll shaft; Described roll shaft and the roll body formation inner chamber of working in coordination; Have through hole in the described roll shaft; Described through hole internal fixing is connected with water pipe; Described roll shaft extends to the end of roll body; Have several apertures on the described roll shaft; Described inner chamber communicates by aperture with through hole.
Preferably, the quantity of described aperture is four.
Preferably, described water pipe is fixedly linked by back up pad and roll shaft.
Because the utilization of technique scheme, the present invention compared with prior art has following advantage:
Steel pipe reheating furnace roller-way of the present invention, roll shaft is elongated to the roll body end, to increase the supporting role to the stressed position of roll body, prevent the fracture of roll body, water coolant enters into the inwall of roll body simultaneously, directly roll body is cooled off, and guarantees that roll body can hardness not descend because temperature is too high, avoid roll body and steel pipe adhesion, cause steel tube surface to form pit.

Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation that the steel pipe reheating furnace of prior art is used roller-way;
Accompanying drawing 2 is the structural representation that steel pipe reheating furnace of the present invention is used roller-way;
Accompanying drawing 3 is the part sectioned view of A;
Wherein: 1, roll body; 2, first cover plate; 3, second cover plate; 4, roll shaft; 5, water pipe; 6, inner chamber; 7, through hole; 8, back up pad; 9, aperture.
Embodiment
Below in conjunction with accompanying drawing the present invention is described.
Of the present invention a kind of steel pipe reheating furnace roller-way shown in accompanying drawing 2-3 comprises roll body 1, first cover plate 2, second cover plate 3, roll shaft 4 and water pipe 5; Described roll body 1 two ends are fixedly connected with first cover plate 2 and second cover plate 3 respectively; Described roll body 1 center is provided with supporting roll shaft 4; Described roll body 1 is worked in coordination with roll shaft 4 and is constituted inner chamber 6; Have through hole 7 in the described roll shaft 4; Described through hole 7 internal fixing are connected with water pipe 5; Described roll shaft 4 extends to the end of roll body 1; Have several apertures 9 on the described roll shaft 4; Described inner chamber 6 communicates by aperture 9 with through hole 7; The quantity of described aperture 9 is four; Described water pipe 5 is fixedly linked by back up pad 8 and roll shaft 4.
Steel pipe reheating furnace of the present invention, roll shaft is elongated to the roll body end, can be used for strengthening the supporting role to the stressed position of roll body, make water coolant enter the inwall of roll body simultaneously, can directly cool off roll body, the hardness on roll body surface can not reduce, so just avoided roll body and the high-temperature steel tube of carrying to stick together, cause steel tube surface to form pit one by one, influenced production efficiency of products, reduced production cost.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
