Detailed description of the invention
The present invention is a kind of bearing calibration of deformed fire path wall of roasting furnace.
Related terms first by involved in roaster before describing bearing calibration of the present invention is self-defined as follows:
Composition graphs 3 and Fig. 4, it is natural integer that roaster is provided with N(N) the equal and longitudinal flue wall be parallel to each other in bar interval, the spacing playing the longitudinal flue wall of Article 1 and the longitudinal flue wall of Article 2 is from left to right referred to as quirk, the longitudinal flue wall of Article 2 and the longitudinal flue wall of Article 3 are parallel to each other by two and the equal horizontal flue wall of length is divided into several equal rectangle hoppers of volume, the long limit of rectangle hopper is set as C rice, the minor face of rectangle hopper is set as K rice, the degree of depth of rectangle hopper or be highly set as G rice.Under normal circumstances, the long limit C=7 rice of rectangle hopper, about the minor face K=0.72 rice of rectangle hopper, the degree of depth of rectangle hopper or height G=5 rice.The longitudinal flue wall of N bar is determined according to the design condition of roaster.
Upper, middle and lower three layers of carbon annode block can be piled up by auxiliary material in each rectangle hopper, the volume of carbon annode block is approximately that 6.5 × 0.6 × 1.5(is long × wide × high) about rice, under the effect of auxiliary material, carbon annode block is calcined by quirk, longitudinal flue wall and horizontal flue wall are assembled by refractory brick, the width of wall body of longitudinal flue wall and horizontal flue wall is substantially equal, the spacing of the longitudinal flue wall of Article 3 and the longitudinal flue wall of Article 4 forms quirk again, the longitudinal flue wall of Article 4 and the longitudinal flue wall of Article 5 are divided into again several equal rectangle hoppers of volume by horizontal flue wall, by that analogy to the spacing of (N-1) article longitudinal flue wall and N article of longitudinal flue wall forms quirk, by longitudinal flue wall and horizontal flue wall because the direction making body of wall bend in rectangle hopper by the change of refractory brick thermal stress and to tilt is referred to as internal strain, by longitudinal flue wall and horizontal flue wall because the direction making body of wall bend outside rectangle hopper by the change of refractory brick thermal stress and to tilt is referred to as outer distortion.The most important condition of internal strain and outer distortion is the same rectangle hopper of pointer, enterolithic flue wall this rectangle hopper relative to the direction tilted that bend is convex-shaped, the flue wall of outer distortion this rectangle hopper relative to the direction tilted that bend is concave shape, the relatively adjacent rectangle hopper of internal strain that in this rectangle hopper, a certain flue wall occurs just becomes outer distortion, the relatively adjacent rectangle hopper of outer distortion that in this rectangle hopper, a certain flue wall occurs just becomes internal strain, therefore internal strain and outer distortion must for same rectangle hoppers.Rule of thumb there is enterolithic probability higher, no matter be internal strain or be out of shape outward, the just bad filling carbon annode block and need to implement to correct to deformed fire path wall in rectangle hopper when its deflection reaches 0.5 ~ 0.11 meter.
Composition graphs 1 and Fig. 2, first bearing calibration of the present invention devises a set of school wall telephone, and the basic comprising of school wall telephone comprises cross wall push pedal 1, transverse hydraulic cylinder 2, hinged-support 3, frame 4, vertical wall push pedal 5, lower longitudinal hydraulic cylinder 6, upper longitudinal hydraulic cylinder 7, skirting 8 and balancing weight 9.
The lower end of the cross wall push pedal 1 of two pieces of area equation is separately fixed at arranged on left and right sides below frame 4 by respective hinged-support 3, the upper end of two pieces of cross wall push pedals 1 is separately fixed at arranged on left and right sides above frame 4 by respective transverse hydraulic cylinder 2, and transverse hydraulic cylinder 2 structure is identical and stroke is equal for two pieces of cross wall push pedals 1, two of using.
The vertical wall push pedal 5 of three pieces of area equation is fixed on the same side of frame 4 side by side by upper longitudinal hydraulic cylinder 7 of each self-configuring and lower longitudinal hydraulic cylinder 6, each vertical wall push pedal 5 not only structure is identical and surface area is also identical and be configured with that the upper longitudinal hydraulic cylinder 7 of longitudinal hydraulic cylinder 7 and lower longitudinal hydraulic cylinder 6, three is identical with hydraulic cylinder 6 structure longitudinal under three respectively and stroke is equal.
The area of skirting equals the gross area of the vertical wall push pedal of three pieces of area equation, and skirting is fixed on the another side of frame.
At the bottom even configuration balancing weight 9 of frame 4, under two 2, three, transverse hydraulic cylinders go up longitudinal hydraulic cylinders 7 and three, longitudinal hydraulic cylinder 6 is by a hydraulic power unit fuel feeding, hydraulic power unit is fixed in frame, and under two 2, three, transverse hydraulic cylinders go up longitudinal hydraulic cylinders 7 and three, longitudinal hydraulic cylinder 6 is all implemented to control separately by respective gauge tap.For producing injury to non-deformed fire path wall when alleviating school wall telephone work, except skirting is set, also will strengthen the deadweight steadiness of school wall telephone, balancing weight 9 role strengthens the deadweight steadiness of school wall telephone just, and the quantity and weight of balancing weight 9 can be determined according to actual needs voluntarily.
Long limit and the minor face of the length in the wall telephone appearance and size of school and width reference rectangle hopper also deduct different surplus respectively, height in the wall telephone appearance and size of school is greater than the height of carbon annode block, and the height of cross wall push pedal and vertical wall push pedal and width and school wall telephone overall volume match.
If long limit × minor face × highly=C × K × G=7 rice × 0.72 of setting rectangle hopper meter × 5 meters, the length of carbon annode block × wide × high=6.5 meters × 0.6 meter × 1.5 meters, then the overall volume of school wall telephone can mate for length×width×height=6.4 meter × 0.58 meter × 2.0 meters, height × width=1.5 of cross wall push pedal meter × 0.56 meter, height × width=1.5 of vertical wall push pedal meter × 1.0 meters, height × width=1.5 of skirting meter × 3.0 meters.
Above-mentioned each parameter value is only for reference.Because the amount of capacity of each roaster is indefinite, rectangle hopper specification is not identical yet, its specification of carbon annode block loaded in rectangle hopper is caused also to be not quite similar, therefore the appearance and size one of school wall telephone is will with the specification of rectangle hopper and carbon annode block for foundation, two is the deflections will considering flue wall, and the appearance and size of school wall telephone is followed and is as the criterion with the rectangle hopper that can load distortion smoothly.
The correcting value of school wall telephone is determined by the stroke of each hydraulic cylinder, and the correcting value of school of the present invention wall telephone can reach more than 120mm, once can complete the correction work of flue wall deflection when 50 ~ 110mm.In fact just correct when flue wall deflection reaches 50mm, now minimum to the damage of flue wall.
Composition graphs 3 and Fig. 4, for sake of convenience, assuming that the horizontal flue wall of the longitudinal flue wall in the left side of a certain rectangle hopper and its both sides all there is internal strain and internal strain amount reaches 0.5 ~ 0.11 meter time, on the left side of this rectangle hopper, there is left rectangle hopper, on the right of this rectangle hopper, there is right rectangle hopper, rectangle hopper before the front of this rectangle hopper has, rectangle hopper after the back of this rectangle hopper has, now first in this rectangle hopper, load onto two-layer carbon annode block and auxiliary material on layering uniform spreading, described right rectangle hopper is set to empty van, auxiliary material is filled with by described left rectangle hopper, described front rectangle hopper and rear rectangle hopper are set to empty van equally, join suspender high-ranking officers wall telephone by overhead traveling crane with institute put into this rectangle hopper and make three pieces of vertical wall push pedals just to enterolithic longitudinal flue wall, skirting on the wall telephone of school is just to undeformed longitudinal flue wall, start the gauge tap of two transverse hydraulic cylinders, two pieces of cross wall push pedals act on two enterolithic horizontal flue walls on around hinged-support to external expansion by the thrust of respective transverse hydraulic cylinder, because described front rectangle hopper and rear rectangle hopper are set to empty van, therefore the horizontal flue wall of two internal strains can be restored respectively, when two enterolithic horizontal flue walls return to original position, two transverse hydraulic cylinders quit work and pressurize five to ten minutes, the correction just completing the horizontal flue wall of two internal strains behind the gap stayed because pushing away wall is filled up until auxiliary material, while startup two transverse hydraulic cylinder gauge taps, the gauge tap of longitudinal hydraulic cylinder under simultaneously starting three, the lower end of three pieces of vertical wall push pedals is made first to lean against the lower end of the longitudinal flue wall of internal strain, and then start the gauge tap of three upper longitudinal hydraulic cylinders, the upper end of three pieces of vertical wall push pedals is made to act on the end of enterolithic longitudinal flue wall to external expansion gradually, when the upper end of three pieces of vertical wall push pedals and its lower end are all in vertical configuration, three upper longitudinal hydraulic cylinders quit work and pressurize five to ten minutes, now school wall telephone can produce a propulsive thrust relatively, this propulsive thrust can act on skirting, and in left rectangle hopper, be filled with auxiliary material, injury can not be produced to longitudinal flue wall undeformed in this rectangle hopper, the correction just completing the longitudinal flue wall in the internal strain left side behind the gap stayed because pushing away wall is filled up until auxiliary material, join suspender high-ranking officers wall telephone by overhead traveling crane with institute after above-mentioned correction work completes to hang out, carbon annode block is loaded onto again in this rectangle hopper He in other rectangle hopper, the internal strain stress that flue wall exists just can be eliminated, the physical dimension of basic this rectangle hopper of recovery through the sintering of a production cycle and cohesion.
School wall telephone is utilized to carry out timing, auxiliary material can flow in the gap between flue wall and carbon annode block automatically to prevent the resilience of deformed fire path wall, just can eliminate through the sintering of a production cycle and cohesion the distortional stress that deformed fire path wall exists, reach flue wall correction without the object of internal injury
After above-mentioned correction work completes, to notice that the rectangle hopper be corrected also will fill auxiliary material after loading onto carbon annode block especially, because the flue wall corrected still has built-in thermal stress, if take out carbon annode block and auxiliary material, the flue wall corrected still likely partly recovers internal strain.
When there is outer distortion in a certain rectangle hopper, under the above-mentioned assumption: this rectangle hopper is set to empty van, two-layer carbon annode block will be loaded onto and auxiliary material on layering uniform spreading in described right rectangle hopper, auxiliary material is filled with in the right rectangle hopper be close to described right rectangle hopper, described front rectangle hopper and rear rectangle hopper are all loaded onto two-layer carbon annode block and auxiliary material on layering uniform spreading, by overhead traveling crane and join suspender high-ranking officers wall telephone and put into described right rectangle hopper and make longitudinal flue wall that three pieces of vertical wall push pedals are just externally out of shape, skirting on the wall telephone of school is just to undeformed longitudinal flue wall, the gauge tap of longitudinal hydraulic cylinder under starting three, the lower end of three pieces of vertical wall push pedals is made first to lean against the lower end of the longitudinal flue wall of outer distortion, and then start the gauge tap of three upper longitudinal hydraulic cylinders, the upper end of three pieces of vertical wall push pedals is made to act on the end of longitudinal flue wall of outer distortion to external expansion gradually, when the upper end of three pieces of vertical wall push pedals and its lower end are all in vertical configuration, three upper longitudinal hydraulic cylinders quit work and pressurize five to ten minutes, now school wall telephone can produce a propulsive thrust relatively, this propulsive thrust can act on skirting, and in the rectangle hopper of described the right, be filled with auxiliary material, injury can not be produced to longitudinal flue wall undeformed in described right rectangle hopper, the correction just completing the longitudinal flue wall of outer distortion behind the gap stayed because pushing away wall is filled up until auxiliary material, then high-ranking officers' wall telephone hangs in described front rectangle hopper and rear rectangle hopper respectively, externally be out of shape horizontal flue wall by cross wall push pedal to carry out respectively correcting, join suspender high-ranking officers wall telephone by overhead traveling crane with institute after correction work completes to hang out, carbon annode block is loaded onto again in described right rectangle hopper rectangle hopper, in described front rectangle hopper and rear rectangle hopper, the outer distortional stress that flue wall exists just can be eliminated, the physical dimension of basic this rectangle hopper of recovery through the sintering of a production cycle and cohesion.Above-mentioned outer distortion correction need of work high-ranking officers wall telephone hangs out and hangs in three times, and correction work bothers relatively, but calibration result is good.
From the bearing calibration of above-mentioned internal strain and outer distortion, the vertical wall push pedal of school wall telephone and cross wall push pedal always will be aimed at the convex surface of deformed fire path wall and can not be aimed at the concave surface of deformed fire path wall, therefore the rectangle hopper at deformed fire path wall convex surface place is exactly the location of installing school wall telephone, just must load onto two-layer carbon annode block in this rectangle hopper and auxiliary material on layering uniform spreading, and the rectangle hopper at deformed fire path wall concave surface place must be just empty van is corrected in order to deformed fire path wall, this is basic norm of the present invention, under this basic norm, the bearing calibration of deformed fire path wall of roasting furnace of the present invention is not limited to above-mentioned two kinds of correcting modes.
