Description
Technical field
The invention belongs to the temperature field detection technique, be specifically related to device for detecting temperature of sintering bench section.
Background technology
In sintering production process, it is very important correctly grasping the sintering process state, and especially sintering temperature distributes.The operative employee can make accurate judgment to sintering process by sintering box temperature state, take to adjust means such as raw material proportioning, the interpolation water yield, sintering material loading, ignition temperature, sintering negative pressure and revise sintering state, make sintering machine be in best running status, to reach the purpose of energy savings, raising output and quality.
Present stage mainly contains dual mode about the sintering bench section temperature detection both at home and abroad:
(1) thermocouple temperature measurement degree method is inserted in the bellows both sides:
This method is two survey the inserting thermopairs and carry out temperature detection and understand the sintering process state of bellows under sintering machine.
This technology because the temperature detecting point of its setting is few, is difficult to reflect the distribution of sintering process temperature in the sintering bench section temperature detection, secondly its check point also causes detecting the corresponding precision of data and reduces also away from the sintering machine bed of material.The temperature detecting point position does not have the representativeness of whole section temperature, can not reflect the Temperature Distribution situation of whole section, thereby causes the computational accuracy of burning point temperature too low, and the burning point has become the face of grilling thoroughly.
(2) bellows are organized temperature measure more:
This method is that the both sides of bellows under sintering machine are inserted the different many groups thermopair of length and carried out temperature detection and understand the sintering process state.
This technology is in the sintering bench section temperature detection, though the temperature survey dot density has reached requirement, but because thermopair is oversize, can't be installed in the optimum detection position of bellows top near chassis, so the detection position moves down, check point also causes detecting the corresponding precision of data and reduces also away from the sintering machine bed of material.Secondly, a plurality of check points are not in same horizontal section, and the position is unfixing, can not represent the temperature of section, can not reflect the Temperature Distribution situation of whole section, thereby cause the section temperature accuracy of detection too low.
Summary of the invention
The purpose of this invention is to provide a kind of long service life, detect effective device for detecting temperature of sintering bench section.
The objective of the invention is to be achieved through the following technical solutions:
Device for detecting temperature of sintering bench section is included in the sintering machine wind box top near the pre-buried some steel pipes of sintering pallet tail end level, open corresponding with corresponding material layer temperature check point detected the hole on each steel pipe, in steel pipe, insert the thermopair of band, the test side portion of thermopair is positioned near the detection hole of steel pipe around property.
Steel pipe can be determined corresponding size by actual measurement requirement and working condition, detects hole number and distributes and should decide according to the actual detected situation, and general the employing evenly distributes.Because common thermocouple measurement end length and material are all restricted, cause the ordinary hot galvanic couple to be subjected to stopping of process equipment of outside to be inconvenient to pierce in the steel pipe, and be not easy accurately to pierce into and be positioned at conplane different perforate in the steel pipe, therefore the present invention uses the thermopair of band around property, band is injected steel pipe around the thermopair of property, and the length of every thermopair detects the length of hole to the steel pipe outer end corresponding to it.Like this, band can be avoided the space constraint that influenced by process equipment around the use of the thermopair of property, and thermopair that can the big length of easier insertion, make simultaneously that temperature detecting point can maximum possible near the sintering pallet bed of material.The use of steel pipe is on the same horizontal section position of temperature detecting point, and measurement data has more the representativeness of section temperature, has improved the precision and the accuracy of measuring greatly.By Dynamic Data Acquiring analysis to three-dimensional temperature field, device for detecting temperature of sintering bench section institute established model data are consistent with actual sintered layer temperature analysis data trend (high temperature imaging), can correctly reflect chassis section each point temperature deviation, precision can arrive 2 ℃.And thermocouple temperature measurement degree method is inserted in both sides and bellows are organized the deviation that temperature measure almost can not effectively be analyzed the sintering bench section temperature more, because its mounting means determines it can not guarantee that temperature survey point is same section.Adopt pre-buried protection steel pipe to play the effect of good dustproof and waterproof protection detecting element (thermopair), reduced the loss of detector unit,, almost all need to change loss equipment every half a year because thermopair is a consumable accessory.After adopting this method, abnormal waste produced the time limit of replacing above 3 years.
Apparatus of the present invention provide unique pattern on the sintering bench section temperature detection.It is based on around resistance temperature hot in nature and measures a kind of novelty detection mode of detection technique.At first in the selection of detecting element (thermopair), adopted different length around galvanic couple hot in nature, be subjected to the restriction on the process equipment space before having overcome, be difficult to difficulty by predetermined detection point installation and measuring element; Secondly on the check point position of location temperature section, adopt pre-buried protection steel pipe and protected the method that even perforate is located on the steel pipe, realized the even distribution of the temperature detection space of points, improved the precision that bed of material section temperature detects greatly, for the foundation of sintering temperature control and models for temperature field provides more accurate and foundation widely; Adopt pre-buried protection steel pipe also to play the effect that good dustproof and waterproof is protected detecting element (thermopair), the serviceable life of having improved detecting element (thermopair) greatly simultaneously.Generally speaking, the unique pattern that apparatus of the present invention propose on the sintering bench section temperature detection has improved the precision of existing sintering bench section temperature detection greatly, is the once breakthrough on the sintering industry sintering bench section temperature checking method.
Further specify technical scheme of the present invention below in conjunction with accompanying drawing.
