Abstract
The utility model relates to an intermediate frequency furnace for the heat treatment of steel cylinders, which comprises a furnace body, a steel bottle delivery device, a medium frequency induction heater, etc. The furnace body uses a semi-enclosed sealing structure and is divided into an upper layer and a lower layer via an upper heat exchange segment and a lower heat exchange segment. The medium frequency induction heater is arranged in the innermost end of a lower layer of the furnace body for making full use of heat emitted from the heated cylinder. The heat exchange can be carried out with a cold cylinder inside the furnace body. The utility model has the advantages of less energy consumption and high thermal efficiency; the heat treatment of the steel cylinder can be ensured.
Description
The utility model relates to the heat treatment heating furnace in the steel cylinder production process.
What existing steel cylinder thermal treatment intermediate frequency furnace generally adopted is the direct-cooled type of single directly-heated, that is: cold bottle directly enters the inductor block heating from an end fire door, is heated to specified temperature and keeps certain hour, withdraws from induction heating from the other end fire door then and cools off.The shortcoming of this single-decker oven body structure is: (1) heat scatters and disappears many, and energy expenditure is big, and efficient is low; (2) to thermal treatment temp, its heat-up rate is fast by cold bottle direct heating for steel cylinder, and temperature is not steady in the stove, difficult control of temperature, though steel cylinder after heat treatment the unit elongation of its material raising is arranged, its intensity reduction is more.
The purpose of this utility model is for overcoming the deficiencies in the prior art part, provides a kind of utilization heat that the high temperature bottle after heating distributes that cold bottle is carried out preheating, thereby improves thermo-efficiency, cut down the consumption of energy, and guarantees the steel cylinder thermal treatment intermediate frequency furnace of thermal treatment quality.
The technical solution of the utility model is such: steel cylinder thermal treatment intermediate frequency furnace, include body of heater, be loaded on intravital steel cylinder e Foerderanlage of stove and medium frequency induction heater etc., special feature is the sealed structure that body of heater is semi-surrounding, the steel cylinder e Foerderanlage is upper and lower heat exchange joint, upper and lower heat exchange joint is divided into body of heater upper and lower two-layer, and medium frequency induction heater is arranged at the inner end of body of heater lower floor.Further, upper and lower heat exchange joint is made of hinge wheel and chain, and by the heat exchange actuator drives, the steel cylinder radial rolling is transmitted.The inner end correspondence that goes up the heat exchange joint in the body of heater is provided with the reversing system that steel cylinder is axially transmitted, reversing system is made of shift fork on sprocket wheel, chain, the chain and reverse drive gear, the below of corresponding reversing system is provided with the cylinder lifting device and transposition pushes away a bottle cylinder, steel cylinder can be pushed medium frequency induction heater, the outlet of medium frequency induction heater is then docked with following heat exchange joint.
Fig. 1 is a plan structure synoptic diagram of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the B-B sectional view of Fig. 2.
Below in conjunction with drawings and Examples structure of the present utility model and advantage are described further.
Referring to Fig. 1, Fig. 2 and Fig. 3, present embodiment mainly comprises body of heater 3, pot carrying machine structure, upward heat exchange joint 12, following heat exchange joint 13, reversing system, medium frequency induction heater 19, cylinder lifting device 17, transposition push away bottle cylinder 16, transfer limes 4 etc.
The pot carrying machine structure is arranged at the port of body of heater 3, is made of lifting gear 1, sprocket wheel 8,10, chain 9 and bottle supporting frame 7, radially steel cylinder 22 is promoted to body of heater 3 ports; Upper and lower heat exchange joint 12,13 is made of hinge wheel 11,14, chain and heat exchange transmission mechanism 6, radially steel cylinder 22 is carried the bodies of heater 3 of coming in and going out; Reversing system is made of sprocket wheel 15,21, chain 18, shift fork 20 and reverse drive gear 5, in body of heater 3 steel cylinder 22 is axially carried.
Working process is such: the pot carrying machine structure is moved upward by the bottle supporting frame 7 promotion steel cylinders 22 that sprocket wheel 8 and 10 drives on the chain 9 by lifting gear 1, cold bottle is sent on body of heater 3 ports on the heat exchange joint 12, drive upper and lower heat exchange joint 12 and 13 by heat exchange transmission mechanism 6 by hinge wheel 11 and 14 and press the beat motion, beat of every motion, each replenishes a steel cylinder 22 upper and lower layer, and each 22 1/3 week of spin of steel cylinder.When the upper strata steel cylinder moves to the end of heat exchange joint 13 (as Fig. 2 B-B sectional view position), transmission mechanism 5 by reversing system is pushed into steel cylinder 22 on the cylinder lifting device 17 by sprocket wheel 15 and 21 shift forks 20 that drive on the chain 18, cylinder lifting device 17 descends, after putting in place, push away bottle cylinder 16 by transposition steel cylinder 22 is pushed induction heater 19 internal heating, and the steel cylinder 22 that has heated the front is pushed into down on the heat exchange joint 13, when the output that the steel 22 on the heat exchange instantly joint 13 moves to outlet pushes away bottle cylinder 2, output pushes away bottle cylinder 2, and that steel cylinder is released body of heater 3 is outer to transfer limes 4, so far finishes the one action process.
Such structure makes full use of the heat of elevated temperature heat bottle behind induction heating, carries out cold and hot amount exchange, makes cold bottle obtain higher preheating temperature before entering induction heating, thereby cuts down the consumption of energy, and makes that temperature tends to be steady in the stove.After tested, steel cylinder of the every processing of the utility model intermediate frequency furnace can economize on electricity 0.584 kilowatt-hour, each stove can be handled 540,000 of steel cylinders every year, economized on electricity 31.5 ten thousand kilowatts hours, save nearly 360,000 yuans, and make steel cylinder thermal treatment reach the standard-required that national pressurized vessel eliminates stress, guaranteed the unit elongation and the unlikely reduction of intensity of steel cylinder material again, guaranteed the steel cylinder thermal treatment quality.
