Abstract
The utility model relates to a double acting stepping blank heating furnace, which comprises a heating furnace body (1), an immobile beam (2) fixed on the furnace body, a walking beam (3) and a stepping driving mechanism (4), wherein a plurality of blank whirling apical teeth with certain shape are arranged on the immobile beam and the walking beam, characterized in that at least two groups of blank whirling apical teeth are mounted on the walking beam and at least three on the immobile beam, the two groups of walking beams are both linked by the same stepping driving mechanism, thereby stepping at the same time, or the two groups of walking beams can be linked by two stepping driving mechanisms respectively, thereby driving the stepping solely. A spread of the apical tooth tube billet provided with single blank or two blanks are equipped side by side in the interior tube billet, thereby achieving improvement for the operating efficiency and meeting the needs of length of different blank. The utility model is applicable to rolling forging blank for general heating process requirements, in particular the heating of seamless steel tube blank such as common carbon steel, high alloy steel and stainless steel.
Description
Technical field
The utility model belongs to industrial heating furnace equipment, particularly produces the two moving beam step-by-step movement blank heating stove of seamless steel pipe.
Background technology
Heating furnace is the common equipment of heating of metal blank during smelter and forging enterprise produce.At present, be used to heat the heating furnace of steel billet at smelter, particularly in seamless steel tube production, using more now is a kind of belt heating furnace, and this heating furnace speed of service is very fast, and efficient is higher; But owing to the blank that heats in stove is not done to roll, thereby blank heating speed is slower, and very inhomogeneous.Usually be that the blank that contacts with furnace bottom partly heats less than requiring temperature, remaining portion temperature is too high and cause oxidization burning loss.
Another is a walking beam furnace, is used for the heating of fast hot steel billet or similar blanks.As China Patent No. is the walking beam furnace of disclosed steel billet of CN94101144.5 or similar blanks.Form by heating furnace body, built-in beam (Jing Liang), moving beam (step rate), step drive mechanism etc.The a plurality of blank upset top ridges (apical tooth) that on the motion beam, are provided with definite shape.The top ridge interacts in the course of the work, and making can be along its longitudinal axis revolution when blank passes body of heater forward.Because this walking beam furnace has the blank of making upset characteristics, thereby it is even to have blank heating, the advantage that heating-up temperature is convenient to control.Its weak point is to go out a blank successively, is subjected to stepping mechanism and heating furnace body length constraint, and its operating efficiency is restricted.It can satisfy the heating process requirement of general edging part blank, but, require heating not only even for the heating of seamless steel pipe blank, particularly high-alloy steel, stainless-steel seamless pipe blank, and want that discharging is fast, efficient is high, and the length of blank will adapt to the variation that the different size steel pipe requires.
Summary of the invention
The purpose of this utility model is studied at the deficiency that existing step-by-step movement blank heating stove technology exists, step-by-step movement blank heating stove is fully being kept on the basis of advantage, overcome the shortcoming of existence, carry out architecture advances, improved the operational efficiency of equipment, and adapted to the variation of different size steel pipe the charge length requirement.
To achieve these goals, the technical solution adopted in the utility model is:
Two moving beam step-by-step movement blank heating stoves are fixedly linked by heating furnace body, with body of heater, and Jing Liang, moving beam and step drive mechanism are formed together; Several blank upset apical tooths that are provided with on Jing Liang and the moving beam with definite shape; Apical tooth interacts in the course of the work, and making can be along its longitudinal axis revolution stepping when blank passes body of heater forward; Characteristics are: described moving beam has two groups at least, and Jing Liang has three groups at least.The Jing Liang on both sides and body of heater and furnace bottom are fixedly linked together, and middle Jing Liang and furnace bottom are fixedly linked together.Two groups of moving beams are linked to each other stepping simultaneously jointly by a step drive mechanism; Also can link to each other by each free step drive mechanism, drive stepping separately.Apical tooth is placed single blank, double joint blank perhaps placed side by side apart from interior pipe.
The two moving beam step-by-step movement blank heating stove that the utility model provides compared with prior art, have outstanding substantive distinguishing features and significant technological progress, main embody two aspects: at first be that to have made full use of step-by-step movement blank heating stove blank heating even, the advantage that heating-up temperature is convenient to control.Make it go out two blanks (short material) successively, also can go out a blank (long material) successively; Discharging is fast, high efficiency, and adapts to the length requirement that the different size steel pipe changes blank.Secondly not at the length constraint that is subjected to stepping mechanism and heating furnace body, can increase work efficiency effectively.
It can be used for the edging part blank of general heating process requirement, adapts to the heating of seamless steel pipe blanks such as ordinary carbon steel, high-alloy steel, stainless steel especially.

The specific embodiment
Describe the utility model specific embodiment in detail below in conjunction with accompanying drawing.
Shown in Figure 1, two moving beam step-by-step movement blank heating stoves of the present utility model.It is made up of heating furnace body 1, quiet beam 2, moving beam 3 and step drive mechanism 4; Several pipes that are provided with on Jing Liang and the moving beam (general edging part general designation blank) 5 upset apical tooths with definite shape; Apical tooth interacts in the course of the work, and making can be along its longitudinal axis revolution stepping when blank passes body of heater forward; Moving beam has two groups, and Jing Liang has three groups, and the Jing Liang on both sides and body of heater and furnace bottom are fixedly linked together, and middle Jing Liang and furnace bottom are fixedly linked together.Two groups of moving beams 3 are linked to each other by a step drive mechanism jointly, play stepping simultaneously;
Perhaps two groups of moving beam 3 each free step drive mechanisms link to each other, and drive stepping separately.
Shown in Figure 2, two moving beam step-by-step movement blank heating stoves of the present utility model.When heating, a long steel tube blank apical tooth is set apart from the single pipe 5 of interior placement on quiet beam 2 and the moving beam 3.
Shown in Figure 3, two moving beam step-by-step movement blank heating stoves of the present utility model.An apical tooth is set apart from interior pipe double joint pipe placed side by side during two short steel pipes blank heating on quiet beam 2 and the moving beam 3.
