Abstract

The utility model discloses a novel non-magnetic roller which mainly comprises a roller body, connecting shaft heads, a shaft head bolt hole, shaft head stopping shoulders and annular grooves. The whole roller body is in the solid cylinder design, the two ends of the roller body are provided with the two connecting shaft heads, the roller body and the connecting shaft heads are integrally designed, and the shaft head stopping shoulders are designed on the sides, close to the roller body, of the connecting shaft heads. According to the novel non-magnetic roller, the multiple annular grooves are formed in the circumferential direction of the whole roller body, the annular grooves are distributed in the whole roller body at equal interval, therefore, when the roller body bears the thermal state swelling stress and the cold state shrinkage stress, the whole roller body enables the borne stress to be attenuated in a grading mode through the annular grooves, and accordingly the problem that roller surface cracks or internal damage to the roller body is caused by the borne stress is solved.

Description

A kind of novel without the magnetic roller

(1) technical field

The utility model relates to metallurgical industry field, be specifically related in a kind of continuous casting machinery key equipment fan-shaped section M-EMS manipulator without the magnetic roller member.

(2) background technology

Along with the development in epoch, 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 continuous casting production process gradually, magnetic stirrer be at present in the world advanced iron and steel enterprise produce the requisite special metallurgical equipment of high value added product.Stainless steel slab continuous casting, without the magnetic roller, is fan-shaped section M-EMS manipulator core component, and its performance quality is directly connected to the quality (proportion of equiaxed grain) of continuous casting billet.Without magnetic roller device owing to moving in hot environment, therefore whole roll body need bear larger hot expansion and cold conditions shrinkage stress, for this reason, need, in this process, without the magnetic roller member, carrying out certain structural design, adapt to the operating mode of hot expansion and cold conditions shrinkage stress to meet roll body.

(3) summary of the invention

The utility model mainly provide a kind of can meet roll body adapt to hot expansion and cold conditions shrinkage stress operating mode without the magnetic roller member, main technical schemes is as follows:

A kind of novel without the magnetic roller; mainly comprise roll body, connect spindle nose, spindle nose bolt hole, spindle nose shoulder block and cannelure; whole roll body designs for solid cylinder; two ends of roll body are provided with two and connect spindle nose; be mainly used in installing the devices such as bearing, bearing block, 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, spacing for bearing.

As preferably, the utility model is provided with the multiple tracks cannelure on whole roll body is circumferential, and cannelure is covered with whole roll body by same spacing distance.In actual use, because roll body is provided with the multiple tracks cannelure, therefore when this roll body when bearing hot swelling stress and cold conditions shrinkage stress, whole roll body can carry out the classification decay by the stress born by the multiple tracks cannelure, thereby avoids roll body because being subject to stress to produce the problem of roll surface crackle or internal injury.

The utility model mainly is applicable to the fan-shaped section crystallizer second half section conveying device in large-size stainless steel continuous casting plant equipment, the roll body material has been added the element Ni of a large amount of stable austenites on technique, can obtain single-phase austenitic steel, make roll body there is low magnetic conductivity.In addition, also add the 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 there is higher heat resistance and thermal fatigue resistance Crack Extension performance when thering is good high-temperature oxidation resistance, can meet preferably the requirement of Continuous Casting Rolls working condition.

(5) specific embodiment

As shown in attached Fig. 1 and 2; described in the utility model a kind of novel without the magnetic roller; mainly comprise roll body 1, connect spindle nose 2, spindle nose bolt hole 3, spindle nose shoulder block 4 and cannelure 5; 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 installing the devices such as bearing, bearing block; roll body 1 be connected spindle nose 2 and design for integral type; 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 connecting spindle nose 2 lay on roller 1 sides, spacing for bearing.Be provided with multiple tracks cannelure 5 on whole roll body 1 circumferential, cannelure 5 is covered with whole roll body 1 by same spacing distance.

The utility model mainly is applicable to the fan-shaped section crystallizer second half section conveying device in large-size stainless steel continuous casting plant equipment, can meet preferably the requirement of Continuous Casting Rolls working condition.
