Abstract
The utility model discloses a split-type multi-stage non-magnetic roll which mainly comprises roll bodies, a central shaft, transitional connection blocks, roll body locking rings and roll body positioning check rings, wherein the roll bodies are hollow; the roll bodies of the whole non-magnetic roll are jointly arranged into the three-stage form; and the multi-stage split-type assembly manner adopted in roll body assembly can avoid the axial deformation of a large-span non-magnetic roll component, guarantee the concentricity of the whole non-magnetic roll during the actual use, and ensure the operation reliability of overall equipment. Meanwhile, the unique multi-stage split-type design form can facilitate the local replacement and maintenance of large non-magnetic roll equipment, so that the maintenance cost is lowered.
Description
(1) technical field
The utility model relates to metallurgical industry field, is specifically related to the no magnetic roller member in a kind of continuous casting machinery key equipment fan-shaped section crystallizer electromagnetic agitation manipulator.
(2) background technology
Along with development of times, the steel demand with high added value is increasing, and domestic and international many steel mills have all set up the production technology of special steel material in production line.And in the special steel material production process; The development of electromagnetic agitation technology is the key process technology that guarantees the final quality of steel; Abroad since the sixties in 20th century; Electromagnetic agitating technology just becomes one of important process means that improve slab quality in the continuous casting production process gradually, and magnetic stirrer is that advanced in the world at present iron and steel enterprise produces the requisite special metallurgical equipment of high value added product.Stainless steel slab continuous casting does not have the magnetic roller; Be fan-shaped section crystallizer electromagnetic agitation manipulator core component, its performance quality is directly connected to the quality (proportion of equiaxed grain) of continuous casting billet, because some big shaped blooms foundry goods are in the casting processing process; The horizontal span of the transport of its corresponding fan-shaped section crystallizer is bigger; And make the no magnetic roller of this large span integral type owing to receive factor affecting such as roll body distortion, the mechanicalness fault very easily takes place in actual use, thereby brings irreparable damage for whole strand continuous casting working procedure; For this reason; Carry requirement to the large span of big shaped blooms foundry goods in fan-shaped section crystallizer transport, invent a kind of connect reliable, concentricity is secure and the novel no magnetic roller member of detachable demolition and maintenance, ten minutes is necessary.
(3) summary of the invention
The utility model mainly provides a kind of multistage no magnetic roller member that carries out split type Assembly And Disassembly, and main technical schemes is following:
A kind of split type multistage no magnetic roller; Mainly comprise roll body, central shaft, transition contiguous block, roll body binding ring and roll body positioning retainer ring; Roll body designs for hollow shape, and the roll body of whole no magnetic roller member is set to three grades altogether, all is installed on the central shaft through the roll body binding ring; Be provided with three groups of totally six road roll body positioning retainer rings on the central shaft; After each roll body and roll body binding ring utilized screw thread to be torqued-up to fitted position to require, the stopper slot of roll body binding ring just embedded mutually and locking with corresponding roll body positioning retainer ring, and the location that can guarantee this grade roll body is with fixing.The utility model is provided with the transition contiguous block between every grade of roll body, the diameter of transition contiguous block is less than the roll body diameter, and the material of transition contiguous block is consistent with roll body, can guarantee the technological requirement of fan-shaped section crystallizer low permeability.
The utility model is specially adapted to the steel billet transport in the large-size stainless steel continuous casting plant equipment; The material of roll body and transition contiguous block has been added the element Ni of a large amount of stable austeniteizations on technology; Can obtain single-phase austenitic steel, make roll body have low magnetic conductivity.In addition; Also add carbide formers such as a certain amount of B, Al, Ti, Mo, V in the material of roll body and transition contiguous block and carried out solid solution and precipitation strength; Can make this steel grade when having the good high-temperature antioxygenic property, have higher heat resistance and thermal fatigue resistance crack expansibility ability, can satisfy the requirement of continuous casting roller working condition preferably.
The multistage split type fit that adopts in the assembling of the utility model roll body can avoid large span not have the axial deformation of magnetic roller member, guarantees the concentricity of whole no magnetic roller in actual use, guarantees the operational reliability of entire equipment.Simultaneously, unique multistage split-type design form can make things convenient for the local replacing and the maintenance of large-scale no magnetic roller device, to reduce maintenance cost.
(4) description of drawings
Accompanying drawing is the overall structure sketch map of split type multistage no magnetic roller
(5) specific embodiment
Shown in accompanying drawing; The described a kind of split type multistage no magnetic roller of the utility model comprises roll body 1, central shaft 2, transition contiguous block 3, roll body binding ring 4 and roll body positioning retainer ring 5, and roll body 1 designs for hollow shape; The roll body of whole no magnetic roller member is set to three grades altogether; All be installed on the central shaft 2, be provided with three groups of totally six road roll body positioning retainer rings 5 on the central shaft 2, after each roll body and roll body binding ring 4 utilize screw thread to be torqued-up to fitted position to require through roll body binding ring 4; Stopper slot on the roll body binding ring 4 just embeds mutually and locking with corresponding roll body positioning retainer ring 5, and the location that can guarantee this grade roll body is with fixing.The utility model is provided with transition contiguous block 3 between every grade of roll body, the diameter of transition contiguous block 3 is less than the roll body diameter, and the material of transition contiguous block 3 is consistent with roll body 1, can guarantee the technological requirement of fan-shaped section crystallizer low permeability.
The utility model is applicable to the steel billet transport in the large-size stainless steel continuous casting plant equipment.
