Background technology
The slag viscosity tester is a kind of detecting instrument that detects its viscosity for blast furnace secondary product slag, and it mainly acts on is the secondary product slag viscosity that detects blast furnace, prevents the excessive ordinary production that influences blast furnace of blast-furnace slag viscosity.
The principle of work of slag viscosity tester is that first test standard material (castor oil) with a kind of known-viscosity value calculates instrument constant as the measurement standard material, fluid to required detection carries out the detection of torsional angle variable quantity again, at last amassing as viscosity number with instrument constant value and torsional angle variable quantity.The standard substance castor oil has different viscosity numbers under different temperatures.Therefore, before test, must carry out temperature survey, and whether measured temperature accurately directly affects the accuracy of test final data to the standard substance castor oil.
In order to improve the confidence level of test figure, must guarantee the thermometric accuracy of standard substance castor oil.Existing slag viscosity tester extensively adopts the artificial direct temperature measurement of thermometer, though its direct temperature measurement has simple operation and other advantages, but the thermometer direct temperature measurement has defectives such as thermotonus is slow, the reading of thermometer varies with each individual.

Embodiment
Embodiment one
Present embodiment is a kind of viscosity tester that is applied to the slag viscosity test, has the automatic temperature measurement function.Its structure as shown in Figure 1, the top of elevating mechanism 3 is column, body of heater position transducer 6 is settled on the top of column, viscosity torsional angle photoelectric sensor 7 is installed by indexable sleeve kink in column top, viscosity gauge head 8 is equipped with in viscosity torsional angle photoelectric sensor 7 lower ends, and the column middle part is supported heating furnace 9 and the standard substance lubricating cup 5 that the test substance crucible is housed respectively by the sway brace that extends to both sides; Settle temperature sensor in the bottom centre of standard substance lubricating cup 5.
Each sensor is respectively by the external single-chip microcomputer testing circuit 2 that is placed in the computer system 1 of signal lead.Wherein, the signal lead of temperature sensor 4 is outwards derived along the lubricating cup wall, touches element when viscosity gauge head 8 is worked to avoid influencing.Before the test, earlier each parts is installed.When slag temperature rises to or near test when temperature required, the operation detection instrument enters in the castor-oil plant fluid in the standard substance lubricating cup 5 viscosity gauge head 8, writes down the transient temperature of castor oil, and testing software will obtain this value automatically, finish the warm accurate surveying work of oil.
Then, testing software will according to these data calculate the K value of system.The K value calculating method is as follows:
Viscosity calculations formula: η=k Δ θ---(1)
In the formula: η is the standard oil viscosity; K is an instrument constant; Δ θ is the torsional angle variable quantity.
The different η of standard oil different temperatures are known, can look into tables of data and obtain, and Δ θ torsional angle variable quantity is recorded by tester system, so tester K value can obtain by following formula (2):
On this basis, record the torsional angle variable quantity of testing liquid in the body of heater again by 8 transpositions of viscosity gauge head, can accurately draw its practical viscosity rapidly.
Present embodiment has been avoided the slow problem of manual thermometric reaction, simultaneously, has avoided the problems such as distortion as a result because of the generation of operator's reading error, easy and simple to handle, safety, and can stablize thermometric to standard oil.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
