Abstract
The invention relates to a fixed section carrier roller of a continuous casting machine. The fixed section carrier roller of the continuous casting machine comprises a roller body, a roll shaft, a shaft sleeve, a retainer ring and packing. Cooling water channels are formed in the two ends of the roll shaft. A through hole is formed in the middle of the roller body. The roll shaft is arranged in the through hole of the roller body. The retainer ring is arranged on the roll shaft in a sleeving mode and is connected with the roller body in a welded mode. The packing is arranged on the roll shaft in a sleeving mode and makes contact with the retainer ring and the inner wall of the through hole of the roller body. The roll shaft is sleeved with the shaft sleeve, and the shaft sleeve is fixedly connected with the roller body through a bolt. The whole fixed section carrier roller is ingenious in structural design, convenient to disassemble, assemble, maintain and replace, and low in cost; the retainer ring is welded between the roller body and the roll shaft and the packing is arranged in the retainer ring to serve as a sealing ring, when the roller body leaks water, the bolt is tightened to fasten the shaft sleeve to abut against the packing according to the site conditions, the packing is made to compress the retainer ring, and cooling water is prevented from leaking out of the roller body; accordingly, the frequency of production halt offline maintenance is greatly reduced, the time of production half offline maintenance is greatly shortened, the production time is indirectly prolonged, and the yield is increased.
Description
Technical field
The invention belongs to the technical field of steel-making continuous casting equipment, the canned paragraph support roller device specifically in a kind of conticaster.
Background technology
In steel continuous casting production process, the durability of canned paragraph carrying roller directly affects the efficiency of bloom production.What in existing conticaster, canned paragraph carrying roller adopted is the structure that roll shaft and roller are directly weldingly connected, roll shaft being provided with bosh and passing into cooling water to its inside prevents roller from not baked bad by high temperature billet steel to carry out internal water cooling to roller, but cause occurring gap between roll shaft and roller and occur drainage due to the effect of expanding with heat and contract with cold of high temperature, and then make quality cooling water flow to steel billet affecting steel billet.Current domestic each producer does not all find the effective way solving this problem, often can only stop production and roll off the production line to maintain roller, so both waste manpower and waste fund, also cause continuous casting steel billet efficiency low, produces bring huge loss to steel plant.In view of the technical problem existed in prior art, therefore, a kind of novel idler structure of exigence solves above-mentioned technical problem.
Summary of the invention

To achieve these goals, the technical solution used in the present invention is, a kind of conticaster canned paragraph carrying roller, comprise roller, roll shaft, axle sleeve, back-up ring and packing, the two ends of described roll shaft offer bosh, the middle part of described roller offers through hole, described roll shaft is arranged in the through hole of roller, described shield ring sleeve is on roll shaft, and connect with roller welding, described packing is enclosed within roll shaft, and contacts with back-up ring and roller through-hole wall, described axle sleeve is enclosed within roll shaft, and is fixedly connected by securing member and roller.
As a modification of the present invention, the two ends of described roller offer circular groove, and be spaced apartly provided with three screwed holes groove is first-class, offer chamfering in 3*45 ° at the two ends of roller through hole, offer at roller axle end the 1.5*45 ° of rounding that radius is 2 millimeters.
As a modification of the present invention, described packing is the circular sealing ring adopting the braiding of expanded graphite line.This kind of packing has good self lubricity and thermal conductivity, and its coefficient of friction is little, and flexibility is good, and intensity is high, has protective effect to axostylus axostyle.
As a modification of the present invention, be provided with the screw thread of Rc3/4 at the bosh notch place of described roll shaft, the depth of thread is 20 millimeters, and the advantage of this screw thread is band tapering and has sealing effectiveness, prevents axle two ends from occurring drainage after water flowing; Thread size is determined according to discharge in roller during production.
As a modification of the present invention, described axle sleeve is T-shaped axle sleeve, is spaced apartly provided with the screwed hole that three apertures are 10 millimeters axle sleeve is first-class, and on axle sleeve hole, is provided with chamfering in 3*45 °.
As a modification of the present invention, because carbon steel cost is low, and performance range is wide, therefore described back-up ring adopts Q235 carbon steel to make, be provided with the outer chamfering of 5*45 ° in the side of described back-up ring, to facilitate the electric welding field between back-up ring and roller, strengthen the fastness of electric welding simultaneously.
As a modification of the present invention, J507 alkaline low-hydrogen electrode is adopted to weld with back-up ring described roller, weld bead height is between the two 5 millimeters, the flatness ensureing described back-up ring surface is needed, so that the installation of described packing, in addition after welding, need after welding to eliminate internal stress, temperature is 600 ~ 650 DEG C, and is incubated 1 ~ 2 hour, finally carries out machined.
As a modification of the present invention, described securing member is 8.8 grades of hexagon-headed bolts.
As a modification of the present invention, described back-up ring adopts the preheat temperature of 150 ~ 250 DEG C to carry out the pre-heat treatment before fixing with described roller welding.
As a modification of the present invention, described roller and roll shaft adopt 45# oil steel to make, and carry out the process of normalizing HB210 ~ 230 after roughing.
Relative to prior art, overall construction design of the present invention is ingenious, disassembly and assembly convenient maintenance and replacement, and cost is lower; By welding a back-up ring between roller with roll shaft, and put into packing as sealing ring on back-up ring side, according to field condition when drainage appears in roller, tight a bolt because fastening shaft sleeve makes it withstand packing, allow packing press back-up ring, prevent cooling water from spilling roller outer; Thus greatly reduce the number of times and time that stop production and roll off the production line and maintain, indirectly add the production time, add output.
