Description
Technical field
The utility model relates to mechanical field, relates in particular to a kind of walking beam furnace.
Background technology
According to statistics: domestic each large Metallurgical Enterprise at present, the heating of pipe blank type of furnace of using, roughly be divided into rotary heating furnace, inclined-bottom heating furnace and roller hearth type heating furnace etc., and above-mentioned several type of furnaces are in use, exist respectively as power consumption, the problems such as pipe distortion, for example: the shortcoming of rotary heating furnace: 1, mechanical means is complicated, and floor space is large, and investment cost is high; 2, gapped between blank, hearth area utilization ratio is low, and intensity of hearth is low; 3, loading door and discharge door are at a distance of too near, and feeding and discharging are too narrow at a distance of region, inconvenient operation.4, higher to the length requirement of pipe, can only scale heating.Sloping Hearth Heating Furnace shortcoming: 1, mechanization degree is low, labour intensity is large; 2, yield poorly; 3, heating of pipe blank is inhomogeneous, and thermo-efficiency is low; 4, metal loss is large.The shortcoming of roller hearth type heating furnace: 1, stopping property is poor; 2, furnace roller is easily crooked; 3, steel tube head is easily encountered furnace roller.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiency that prior art exists, and a kind of heating furnace is provided.
For solving the problems of the technologies described above, the utility model provides a kind of walking beam furnace, it comprises body of heater, and the hydraulic efficiency system, water cooling system, firing system and the electric control system that are installed on described body of heater inside, described body of heater two ends are also provided with feeding unit and drawing mechanism, it is characterized in that: in described body of heater, also set up stepped start-stop system device, described stepped start-stop system device is connected between described feeding unit and described drawing mechanism, described stepped start-stop system device comprises two groups of fixed beams and one group of walking beam, and described walking beam below is provided with several stepping mechanisms.
Further, described stepping mechanism is comprised of bottom girder, translation mechanism and hoisting appliance again, described translation mechanism and described bottom girder are actively coupled, and described bottom girder connects with described walking beam, described translation mechanism and described hoisting appliance separately be fixedly installed on described bottom of furnace body.Described translation mechanism can drive walking beam reach and retreat, and described hoisting appliance can drive walking beam to raise and reduce.When hoisting appliance raises, drive translation mechanism to raise, translation mechanism makes the walking beam segment distance that travels forward simultaneously, and when hoisting appliance reduces, translation mechanism decreases and make walking beam reset.
Further, described hoisting appliance is comprised of support roller and sloping bottom liner plate, and described support roller is clamped in the upper and lower both sides of described bottom girder; Described translation mechanism comprises the bottom girder guide type shoe of stationary installation and is fixed on the walking beam pedestal fairload composition on described bottom girder guide type shoe.
Further, described walking beam is positioned at described fixed beam below.
The beneficial effects of the utility model are: the utility model adopts stepped heating, and due to its special progression, being heated evenly property is good, and thermo-efficiency reaches 92%.The hoisting appliance control step beam of stepping mechanism rises and declines, and translation mechanism control step beam moves forward and backward, and often further when walking beam, pipe can rotate an angle and misplace and advance, thereby can make pipe better be heated, improves quality; Can reduce production loss in addition, reduce floor space.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is vertical view of the present utility model.
In figure: 1, body of heater; 2, sloping bottom liner plate; 3, bottom girder guide type shoe; 4, bottom girder; 5, walking beam pedestal fairload; 6, walking beam; 7, support roller; 8, feeding unit; 9, fixed beam; 10, firing system; 11, drawing mechanism; 12, stepping mechanism; 13, translation mechanism; 14, hoisting appliance.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further set forth.
As depicted in figs. 1 and 2, a kind of walking beam furnace, it comprises body of heater 1, and the hydraulic efficiency system, water cooling system, firing system 10 and the electric control system that are installed on body of heater 1 inside, body of heater 1 two ends are also provided with feeding unit 8 and drawing mechanism 11, have also set up stepped start-stop system device in body of heater 1, and stepped start-stop system mechanism is connected between feeding unit 8 and drawing mechanism 11, stepped start-stop system device comprises two groups of fixed beams 9 and one group of walking beam 6, and walking beam 6 is positioned at fixed beam 9 belows.Walking beam below is provided with several stepping mechanisms 12.
Stepping mechanism 12 is comprised of bottom girder 4, translation mechanism 13 and hoisting appliance 14 again, and translation mechanism 13 is actively coupled with bottom girder 4, and bottom girder 4 connects with walking beam 6, translation mechanism 13 and hoisting appliance 14 separately be fixedly installed on body of heater 1 bottom.Hoisting appliance 14 is comprised of support roller 7 and sloping bottom liner plate 2, and support roller 7 is clamped in bottom girder, and Shang Xia 4 both sides; Translation mechanism 13 comprises the bottom girder guide type shoe 3 of stationary installation and is fixed on walking beam pedestal fairload 5 compositions on bottom girder guide type shoe 3.
As depicted in figs. 1 and 2, pipe is put into after feeding unit 8, pipe is transported on fixed beam 9, now the hoisting appliance 14 by HYDRAULIC CONTROL SYSTEM stepping mechanism 12 rises, when hoisting appliance 14 rises, drive bottom girder 4 to raise simultaneously, because translation mechanism 13 and grade beam 4 are coupled to each other, so the support roller 7 of translation mechanism 13 moves to upper left side along sloping bottom liner plate 2, walking beam now 6 raises and higher than fixed beam 9, drag pipe dislocation and advance, the pipe after advancing will produce certain displacement angle, for the good condition that provides is better provided.Then hoisting appliance 14 drives bottom girder 4 and translation mechanism 13 motions, the support roller 7 of translation mechanism 13 moves to lower right along sloping bottom liner plate 2, walking beam 6 now will be lower than fixed beam 9, pipe stops certain hour and heats, and the above step that constantly circulates is afterwards carried out stepped start-stop system promotion pipe and advanced.
