Abstract
The utility model discloses a chain type heat treatment furnace used for normalizing and temper heat treatment of large-diameter seamless steel pipe in the technical field of heat treatment equipment. The chain type heat treatment furnace has reasonable structure, high working efficiency and good quality of heat-treated product, and is characterized in that a furnace bottom slide rail is arranged on a furnace bottom. One side of the chain type heat treatment furnace is provided with at least two driving gears which are connected with each other by a connecting shaft. The other side of the chain type heat treatment furnace is provided with driven gears respectively corresponding to each driving gear. Each driving gear and the driven gear corresponding to the driving gear are sleeved with a transmission chain. The transmission chain is connected with a plurality of shifting claws by a hinge. An isolation space is arranged between the adjacent two shifting claws. In addition, the chain type heat treatment furnace also comprises a driving device which can drive one of the driving gears to rotate.
Description
Technical field
The utility model belongs to the Equipment for Heating Processing technical field, relates in particular to a kind of heat treated chain type heat treatment furnace of normalized and tempered that is used for weldless steel tube.
Background technology
Existing a kind of weldless steel tube heat treatment furnace is made up of body of heater, combustion control system, furnace bottom live rollers system etc., and this process furnace is used for the usefulness of the thermal treatment heating of minor-diameter steel-tube.Steel pipe is discharged neat back and is sent in the stove along the steel pipe longitudinal direction by the stokehold charging roller.At first the head of steel pipe enters and begins heating in the stove, then along with the rotation of furnace bottom roller-way, steel pipe progressively is admitted in the process furnace to be heated, and steel pipe moves along the furnace superintendent direction and finishes thermal treatment heat-processed, and the steel pipe that heating is finished is transported out by roller-way behind the stove at last.The thermal treatment of small-caliber steel pipe during this heat treatment furnace only is applicable to then exists steel pipe vertically to reach the problem of circumferential furnace temperature inequality to large diameter steel pipe, thereby influences the steel pipe heat treatment performance; And because the longitudinally first post-heating of steel pipe, longitudinally there is the bigger temperature difference in steel pipe, causes the steel pipe cracking easily for the stronger steel alloy of heat sensitivity.Furthermore, because steel pipe does not circumferentially rotate in heat-processed, the effect steel pipe of the temperature difference bends easily.
The utility model content
Technical problem to be solved in the utility model provides a kind of rational in infrastructure, production efficiency height, the chain type heat treatment furnace that the product thermal treatment quality is good.
The utility model comprises furnace bottom, and the furnace bottom slide rail is set on the furnace bottom, arranges at least two driving toothed gears in a side of chain type heat treatment furnace, and driving toothed gear interconnects by a coupling shaft; Correspond to each driving toothed gear at the opposite side of chain type heat treatment furnace and arrange passive gear respectively, each driving toothed gear and with the corresponding passive gear of described driving toothed gear on the socket driving chain, be hinged several pusher dogs on the described driving chain, be provided with clearance space between two adjacent pusher dogs; In addition, the chain type heat treatment furnace also comprises the drive unit that can drive one of them driving toothed gear rotation.
As improvement of the present utility model, described drive unit comprises a rotating machine, socket one chain on the output terminal of described rotating machine, and described chain is socketed on one of them driving toothed gear simultaneously.
As further improvement of the utility model, the outstanding outward spacing protuberance that forms of a side direction of each the pusher dog bottom that is hinged on the driving chain.
Compare with existing weldless steel tube heat treatment furnace, the pusher dog that is provided with on the driving chain in the utility model can spur weldless steel tube, make weldless steel tube along laterally the entering in the process furnace of body of heater, owing to be uniformly along stove temperature transversely, so guaranteed weldless steel tube temperature homogeneity longitudinally.Weldless steel tube is being the continuous rolling progressive on the furnace bottom slide rail under the pulling of pusher dog, thereby guaranteed the temperature homogeneity that weldless steel tube is circumferential, and weldless steel tube is played the effect of aligning, guaranteed the straight degree of weldless steel tube, weldless steel tube rolls from burner and advances to the thermal treatment heat-processed that the stove tail has just been finished continous way, improved production efficiency, and good through the tube product quality after the chain type heat treatment furnace thermal treatment in the utility model.

Embodiment
As shown in Figure 1, a plurality of furnace bottom slide rails 2 are set on the furnace bottom 1.Arrange first driving toothed gear 3 and second driving toothed gear 4 on the right side of chain type heat treatment furnace, described first driving toothed gear 3 and second driving toothed gear 4 interconnect by coupling shaft 5.Left side and first driving toothed gear, 3 corresponding location arrangements first passive gear 6, the first driving chains 7 at the chain type heat treatment furnace are socketed on first driving toothed gear 3 and first passive gear 6; Left side and second driving toothed gear, 4 corresponding location arrangements second passive gear 8, the second driving chains 9 at the chain type heat treatment furnace are socketed on second driving toothed gear 4 and second passive gear 8.
As shown in Figure 2, the output terminal of rotating machine 10 cover chain 11, chain 11 is socketed on first driving toothed gear 3 simultaneously.First driving chain 7 is socketed on first driving toothed gear 3 and first passive gear 6.Only express the structure of part first driving chain 7 among Fig. 2,7 of first driving chains of rest part are represented with lines.Be hinged on first driving chain 7 and be connected to several pusher dogs 12, be provided with clearance space between two adjacent pusher dogs 12.Second driving chain 9 is identical with the structure of first driving chain 7, and also being hinged on second driving chain 9 is connected to pusher dog 12.As shown in Figure 3, the outstanding outward spacing protuberance 12-1 that forms of a side direction of each pusher dog 12 bottom.Spacing protuberance 12-1 in the present embodiment is arranged on the left side of pusher dog 12, promptly pusher dog 12 only to the right direction topple over.And the chain type heat treatment furnace tilts, and its left side is low, the right side is high.One end of weldless steel tube 13 is between the wherein a pair of pusher dog 12 on first driving chain 7, and the other end of weldless steel tube 13 is between the wherein a pair of pusher dog 12 on second driving chain 9.Pulling weldless steel tube 13 continuous rolling on furnace bottom slide rail 2 advances when first driving chain 7 and second driving chain 9 are synchronized with the movement.
