Description
Technical field
The invention belongs to the temperature test technical field, particularly a kind of temperature calibrating loop that is used to monitor and proofread the high temperature kiln sintering procedure.
Background technology
The general parts that probe temperature all must be arranged in the kiln sintering procedure, no matter be box-type furnace, vertical heater or tunnel furnace, it is that institute is indispensable in the kiln sintering procedure that temperature is tested, has only test by temperature, could regulate control to the whole sintering process of product, to guarantee the quality of product; The such product of particularly similar pottery just needs very accurately efficient temperature measurement in sintering process, could guarantee the kiln discharge quality of ceramic product.The temperature test parts that prior art is used for the kiln sintering procedure are generally thermopair, thermopair is owing to be subjected to the time and the spatial restriction, be difficult to be placed on simultaneously the arbitrary position of burnt product, so thermopair is the envrionment temperature of energy measurement product only, whole heat effect that can not measure product itself; In addition, thermopair can only measuring radiation warm, and do not relate to the conduction heat from kiln furnitures; Caused the instability of burnt product quality for this reason, product percent of pass is descended.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of applied range is provided, measures burned product and be heated situation accurately and can improve the temperature calibrating loop that is used to monitor and proofread the high temperature kiln sintering procedure that burns till the product qualification rate greatly.
The technical solution adopted for the present invention to solve the technical problems is: a kind of temperature calibrating loop that is used to monitor and proofread the high temperature kiln sintering procedure comprises following chemical feedstocks master composition (weight percent) and micro-additive:
Magnesium oxide 10～36
Potassium oxide 3～14
Barium carbonate 3～18
Titanium dioxide 2～20
Silica 1 5～56
Aluminium sesquioxide 13～38
Described micro-additive comprises following composition (weight percent):
Zinc oxide 0.4～3
Boron trioxide 0.2～1.5
Niobium Pentxoxide 0.1～0.8
A kind of complete processing that is used to monitor and proofread the temperature calibrating loop of high temperature kiln sintering procedure, it comprises the steps:
A. prepare burden: selected chemical feedstocks master composition is carried out weighing according to prescription (weight percent);
B. ball milling: confected materials is poured in the ball mill, added the water of 1～2 times of weight, ball milling 5～12 hours;
C. dry: that the mixture behind the ball milling is put into oven drying;
D. pre-burning: dried powder is pressed into piece, pre-burning under 700～1000 ℃ temperature;
E. reinforced ball milling: add the tackiness agent of micro-additive and adding 8～20% weight ratios in the piece material after pre-burning, put into the ball mill ball milling again 8～12 hours;
F. drying and moulding: the powder behind the ball milling is carried out spray drying granulation, and last dry-pressing becomes annular;
G. burn till the contrast of diameter and temperature: the annular temperature calibrating loop is put into high-temperature electric resistance furnace, under differing temps, be incubated and burn till, accurately measure temperature-diameter synopsis and graphic representation thereof.
The invention has the beneficial effects as follows, owing to adopt magnesium oxide, potassium oxide, barium carbonate, titanium dioxide, silicon-dioxide, chemical feedstockss such as aluminium sesquioxide are main composition, above-mentioned raw materials is weighed by certain formula rate, passing through mixing, ball milling, dry, after the pre-burning, add zinc oxide again, boron trioxide, micro-additive such as Niobium Pentxoxide and a certain proportion of tackiness agent, carry out ball milling, spray drying granulation, last dry-pressing becomes the temperature calibrating loop of an annular, it can together enter in the stove in company with product, bring the difference of diameter to change by the temperature of different positions in the induction furnace, after coming out of the stove, with diameter after the burning of accurately measuring and the diameter of obtaining in advance, temperature synopsis and graphic representation thereof contrast, the temperature of three-dimensional space different positions in must coming out of the stove is to reach the control to the product sintering process.Because the temperature calibrating loop riding position is random, can press close to the actual heating status of product, accurately determine the burned product situation of being heated; Temperature calibrating loop uses maneuverability, but three-dimensional any corner in the stove is measured on simple and convenient ground; The temperature calibrating loop consistence is good, can guarantee the good reproduction of product calcining system, thereby improves the qualification rate of burning till product; Use temperature calibrating loop to reduce even no longer need geometrical shape, density and the porousness of burning till product are measured or destructive test, thereby reduce the quality Control during Production cost.So, temperature calibrating loop is a kind of applied range, not only is applicable to box-type furnace, vertical heater and continuous tunnel furnace, is applicable to that also vacuum and atmosphere burns till occasion, be used to monitor and proofread the situation of being heated of high temperature kiln sintering procedure burned product, and can improve the qualification rate of the product of burning till greatly.
