The heating furnace comprises a furnace body, a steel structure, a heat supply part and a temperature control part and is characterized in that a lateral furnace wall and a furnace cover are both separated in sections, a slit which is filled with a sealing plate with the adjustable width is positioned between every two sections, furnace wall upright posts which support the furnace body are two parallel upright posts welded on a same base plate, a slit positioned between the two parallel upright posts corresponds to the slit positioned between the lateral furnace wall and the furnace cover and is on the same flat surface with the slit positioned between the lateral furnace wall and the furnace cover, and spacings of all the slits are larger than the total width of a rear furnace wall; the rear furnace wall can move, can pass through the slit positioned between the two parallel uptight posts and can also pass through and be placed into the slit without the sealing plate and positioned between the lateral furnace wall and the furnace cover so as to be connected and fixed with each section of lateral furnace wall, thereby the utility mode can achieve the purpose of changing the position of the rear furnace wall and the practical using volume of the furnace cavity according to need.
Description
Technical field
The utility model belongs to process furnace, particularly a kind ofly can change Large Furnace kiln thorax volumetrical process furnace fast.
Background technology
Various pressurized vessels, welding set, its shape, size are different, kind also varies, when carrying out postwelding stress relieving, shape, size and volumetrical to stove require also to have nothing in common with each other, can develop the process furnace that can change its furnace volume fast and satisfy the production needs that often change, the Sustainable development of conveniently producing, save energy and reduce the cost, avoid low load with strong power, reduce production costs and promote national economy is had significance.
The present domestic way that can change furnace volume has two kinds:
First kind: the inventor cooperated with Li Yang in 1993, succeeded in developing assembling (claiming assembling again) formula resistance furnace.The body of heater of this stove is to be made of self-existent unit member----furnace body plate, drop-bottom and frame electric heater, and the process furnace that can be built into different shapes, volume and power as required satisfies the needs of various heat treatment of workpieces heating.The heated furnace volume of having built application is little of 0.6m
3, arrive 2630m greatly
3, power is little of 30 kilowatts, greatly to 3000 kilowatts.Be reconstructed into the stove of different volumes and shape after this kind stove is detachable, also can move the strange land to and rebuild, to satisfy the heat treated needs in heavy construction working-yard, but every dismounting and the once also non-easy thing of assembling, also will expend the regular hour, energy, material resources, transport power are paid certain cost.
Second kind: succeeded in developing the large-scale pallet car type fuel oil heating that a furnace volume can change by Luoyang petrochemical equipment factory in 1998.The fire door of this stove is located on the end face of fire door one end chassis, and fuses with chassis.The periphery of fire door matches with the shape of the cross section of inboard wall of burner hearth, but is slightly less than inboard wall of burner hearth, and the periphery of fire door is equipped with hydraulic seal mechanism.Chassis can drive in the burner hearth and in the position of needs together with fire door and stop, and changes furnace volume by the stop place that changes chassis and fire door, and reduces the quantity of some burner, realizes energy-saving and cost-reducing purpose.The result of use of this stove is good, but also has some problems in using and have certain limitation: stove itself can not be dismantled with the strange land and rebuild, and is difficult to realize the on-the-spot thermal treatment of heavy construction; This technology is only applicable to the smooth car type furnace of inboard wall of burner hearth, is not suitable for being equipped with on the furnace wall bench vehicle type electrical resistance furnace of many electric heating elements, because the fire door on the chassis can damage the electric heating element on the furnace wall when mobile, makes sealing between furnace wall and the fire door more difficult realization that becomes.
Above-mentioned technical barrier is perplexing the people in the industry, needs to be resolved hurrily.
Summary of the invention
