Abstract
The utility model discloses a non-magnetic roller with flume threads on a roller surface. The roller mainly comprises a roller body, connecting shaft heads, shaft head bolt holes, shaft head blocking shoulders and annular flume threads, wherein the whole roller body is a solid cylinder; two connecting shaft ends are arranged at two ends of the roller body; and the roller body and the connecting shaft ends are integrated. A plurality of annular flume threads are formed in the circumferential direction of the whole roller body and distributed on the whole body at the same intervals. During actual use, when the roller body continuously rotates in cooling water, the cooling water which is attached to the roller surface originally can be easily subjected to gravity action and falls down in a centralized mode through the plurality of annular flume threads formed in the circumferential direction, so that the quantity of the cooling water contacted with a high-temperature casting blank is greatly reduced, and the phenomenon that the surface of the casting blank is abnormally oxidized because a large amount of water vapor is evaporated is avoided to a great extent.
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; It is 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 in the second half section course of conveying of fan-shaped section crystallizer, the temperature of strand has obtained descending, often placed bosh in a lot of process units and come no magnetic roller roll body is further lowered the temperature in the no magnetic roll bracket bottom at this position; Promptly let the Lower Half of no magnetic roller be immersed in the water surface of bosh, the no magnetic roller surface of rotation can be immersed in the water continuously and lower the temperature.In this processing step; Because cooling water can be adhered in the smooth no magnetic roller face of cylinder; And in roll surface formation water membrane; Moisture film can flash evapn after touching the strand of high temperature, if evaporate a large amount of steam then can influence the total quality of strand to being in the casting billet surface accelerated oxidation in the process for cooling process and causing irregular peeling off.For this reason, need the no magnetic roller member in this process is carried out the certain structure design, to satisfy the quality requirement of strand process for cooling.
(3) summary of the invention
The utility model mainly provides a kind of can effectively reduce the no magnetic roller member that roll surface adheres to the water yield, and main technical schemes is following:
A kind of no magnetic roller of roll surface band gutter line mainly comprises roll body, connects spindle nose, spindle nose bolt hole, spindle nose shoulder block and annular gutter line, and whole roll body designs for solid cylinder; Two ends of roll body are provided with two and connect spindle nose; Be mainly used in devices such as bearing, bearing block are installed, roll body designs for integral type with being connected spindle nose, on the outside end face that connects spindle nose; Be provided with 6 spindle nose bolts hole, be mainly used in the fixing and sealing of connecting axle head protection end cap.The utility model has also designed the spindle nose shoulder block in connecting axle head rest roll body side, is used for the spacing of bearing.
As preferably, the utility model is provided with multiple tracks annular gutter line on whole roll body is circumferential, and annular gutter line is covered with whole roll body by same spacing distance.In actual use; When roll body constantly rotates in cooling water; Originally attached to the cooling water on the roll surface just can be at an easy rate through many roads annular gutter line of circumferential setting gravitate concentrate and fall downwards; Significantly reduce the cooling water water yield that contacts with the high temperature strand, also eliminated the casting billet surface abnormal oxidation phenomenon that causes because of a large amount of evaporations of steam simultaneously to a great extent.
The utility model mainly is applicable to the fan-shaped section crystallizer second half section transport in the large-size stainless steel continuous casting plant equipment; The roll body material 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 roll body material 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.

(5) specific embodiment
Shown in accompanying drawing; The no magnetic roller of the described a kind of roll surface band gutter line of the utility model mainly comprises roll body 1, connects spindle nose 2, spindle nose bolt hole 3, spindle nose shoulder block 4 and annular gutter line 5, and whole roll body 1 designs for solid cylinder; Two ends of roll body 1 are provided with two and connect spindle nose 2; Be mainly used in devices such as bearing, bearing block are installed, roll body 1 designs for integral type with being connected spindle nose 2, on the outside end face that connects spindle nose 2; Be provided with 6 spindle nose bolts hole 3, be mainly used in the fixing and sealing of connecting axle head protection end cap.The utility model has also designed spindle nose shoulder block 4 in connection spindle nose 2 lay on roller 1 side, is used for the spacing of bearing.
The utility model is provided with multiple tracks annular gutter line 5 on whole roll body 1 circumferential, annular gutter line 5 is covered with whole roll body by same spacing distance.In actual use; When roll body constantly rotates in cooling water; Originally attached to the cooling water on the roll surface just can be at an easy rate through many roads annular gutter line of circumferential setting gravitate concentrate and fall downwards; Significantly reduce the cooling water water yield that contacts with the high temperature strand, also eliminated the casting billet surface abnormal oxidation phenomenon that causes because of a large amount of evaporations of steam simultaneously to a great extent.
The utility model mainly is applicable to the fan-shaped section crystallizer second half section transport in the large-size stainless steel continuous casting plant equipment, can satisfy the requirement of continuous casting roller working condition preferably.
