In the industry furnace of the utility model, the height of the furnace body can be adjusted to apply to the heat treatment of shaft castings and forgings with different lengths, and different machined workpieces have no free space when the heat treatment is carried out in the furnace, so that not only the energy is saved, but also the quality of the heat treatment workpiece is enhanced.
Description
[technical field]
The utility model belongs to machinery, metallurgical technology field, the vertical segmentation heat treatment industrial furnace that particularly a kind of axle class forge piece that is applicable to different lengths is heat-treated.
[background technology]
Usually, the thermal treatment of the forged shaft workpiece of machinery, metallurgy industry adopts whole well formula industrial furnace to finish.Whole pit furnace belongs to large-scale heat treatment industrial furnace, generally according to the physical dimension of the maximum product of its processing and design-build, to be satisfied with the hot-work workpiece of all sizes.But,, make whole well formula industrial furnace have following shortcoming just because of above-mentioned design.It not only to factory building require high, floor space is big, and equipment complexity, laid down cost are high and long in time limit.Except the shortcoming of above-mentioned construction aspect, in the practical application of existing well formula industrial furnace, also there are some shortcomings.For most of enterprises, the large-scale long shaft class workpiece comparatively small amt of its production, and based in, the axle class forge piece of short length.But be subjected to the restriction of existing heat treatment industrial furnace, in these, the processing work of short length also will heat-treat in same industrial furnace, make to have bigger remaining space in the industrial furnace, caused the low phenomenon of space occupancy in the industrial furnace, directly cause the increase of industrial furnace consumes energy.In addition, in, when the shaft-like workpiece of short length is come out of the stove,, quenching process is had a negative impact because that the last space of industrial furnace internal upper part makes processing work shift out in the stove extremely the timed interval of quenching greatly is long, finally influence the quality of heat treated part.Therefore, be necessary the structure of existing whole well formula industrial furnace is improved and innovated, to overcome the above-mentioned defective that exists.
[summary of the invention]
The utility model discloses a kind of vertical segmentation heat treatment industrial furnace, it can adjust the height of body of heater, to be applicable to the thermal treatment of different lengths axle class forge piece, all kinds of processing works do not have remaining space during thermal treatment in stove, like this, but both save energy can improve the quality of heat treated part again.
Technical solution adopted in the utility model: a kind of vertical segmentation heat treatment industrial furnace comprises: by the body of heater skeleton that steel are welded, the furnace lining that the fixed installation refractory materials is made on the skeleton; The furnace bottom of carrying body of heater; Bell movably, the interruption-forming sealing cover closes on bell and the body of heater; Body of heater is formed by several sections upper-lower seal snappings.
Described industrial furnace, the furnace sealing joint is plane, concavo-convex or L shaped up and down.
Described industrial furnace, furnace bottom is provided with workpiece support, and the workpiece lower end is positioned supporting seat, and top is located to supporting mechanism by workpiece side.
Described industrial furnace, the workpiece support of furnace bottom is regulated size according to diameter of work.Workpiece support is divided two portions: base and two bases.One time base is fixedly installed in the body of heater of bottom, on the basis of a base, sets up the secondary base, the secondary base is an annular, this annular base is placed on base, and different size can satisfy the support demand of different workpieces, has reduced the complicacy of frock simultaneously.
Sectional type industrial furnace of the present utility model make full use of the refractory fibre structure light and handy, sealing property is good and the advantage of anti-vibration performance, and body of heater is divided into multi-stage type capable of being combined along short transverse, length according to institute's heat treated part is regulated size of burner hearth, substitutes original whole well formula industrial furnace.When thermal treatment farm labourer part, use all the longest bodies of heater of each section composition; When thermal treatment casual labourer part, the top body of heater can be removed and removed, use the body of heater of remaining each section to get final product.By multi-section combined body of heater solved thoroughly that existing whole well formula industrial furnace real space utilization ratio is low, energy consumption is big, influence technical problem such as quenching process.
Sectional type industrial furnace of the present utility model has the following advantages.At first, most enterprises machining large long-axle workpieces less (account for shaft-like workpiece 15～20%), the middle-size and small-size shaft-like workpiece of a large amount of processing (account for shaft-like workpiece 80～85%), industrial furnace of the present utility model can be regulated the height dimension of burner hearth according to the length of required heat treated part, thereby improve the furnace inner space occupation rate, compare annual capable of reducing energy consumption about 28% with original well formula industrial furnace.Secondly, multi-use improves plant factor, save facility investment, and maintenance of the equipment is simple and easy.Once more, if from now on longer heat treated part arranged, and existing industrial furnace then can undergo technological transformation to it can't adapt to it and use the time, increases the primary reformer body again, can satisfy the heat treatment process requirement, has enlarged use range.At last because length and the body of heater of processing work is suitable, in, lack for the workpiece of length, it has reduced the timed interval midway in quenching process, reach the purpose of rapid quenching, the quality of the workpiece of guaranteeing to quench.
