Description
Technical field
The utility model belongs to the tester class, relates to a kind of trial furnace that is used to test the refractory material refractoriness, particularly a kind of refractoriness test stove that has the tubular type imaging mechanism.
Background technology
Refractoriness is basic, classical, the important performance of refractory material.Its test philosophy is, " the examination awl that refractory raw material or goods are made is planted on the frustum with the standard temperature awl of known refractory degree, and heating and the relatively more curved situation of falling are represented the refractoriness trying to bore under defined terms ".
China's national standard " GB/T 7322-1997 refractory material refractoriness test method " adopting by equation international standard " mensuration of ISO 528:1993 refractory product-Fire-check keys etc. (refractoriness) on duty ".Trial furnace shown in this standard adopts vertical tube furnace (also claiming well formula trial furnace) or batch-type furnace, and the stove planted agent keeps oxidizing atmosphere.
According to test philosophy and national standard, the key technology of test material refractoriness is: 1. heating: according to certain heating rate heating examination awl and standard temperature awl, furnace temperature should be even; 2. record: the curved situation of record examination awl, standard temperature awl; 3. result's judgement: the refractoriness of trying awl with the awl number expression that examination is bored and the most advanced and sophisticated standard temperature that contacts frustum simultaneously of standard temperature awl is bored.
Satisfying the widely used trial furnace of above-mentioned standard, mainly is vertical tubulose cryptol furnace, and its structure is: in vertical barrel type metal furnace shell heat-barrier material is set, is followed successively by heating carbon granule and high temperature resistant magnesia boiler tube in the heat-barrier material.This kind structural test stove, though simple in structure, cost is lower, used heating carbon granule is inexpensive, is easy to obtain, complex operation, labour intensity is big, and the electric heating property instability is difficult to realize automatic control; Power consumption is very big, wastes energy; Try awl, the standard pyrometric cone curved observation and the record of situation, record after the dependence operating personnel detect by an unaided eye, human error is big, and operating condition is poor.
Application number is 92210103.5 and is called the patent of " the rotary refractoriness analyzer of automatic lifting ", in order to overcome the deficiency of kryptol furnace, adopt 4 U-shaped silication molybdenum bar heater annular spread around burner hearth, furnace shell the inside is lined with refractoriness greater than 1800 ℃ light-weight refractory lining, and the side of furnace shell is provided with peep hole; But still the examination of dependence manual observation record is bored, the curved process of standard pyrometric cone.
Application number is 200710053436.7 and is called the patent of " a kind of high-temperature electric resistance furnace that is used to detect the refractory material refractoriness ", vertical installation 4-16 root chromic acid lanthanum rod is a heater in furnace lining, side in the high-temperature region is provided with peep hole, the angle of this peep hole and horizontal plane is greater than 20 °, the observed and recorded of examination awl and standard pyrometric cone adopts the outer video camera of installing of body of heater, and the position for video camera is on the line of frustum and peep hole.The deficiency of this kind structure: after 1. the frustum of installation examination awl, thermometric standard cone is sent into from the body of heater bottom, dim dull thread in the body of heater when low temperature, the display of video camera and display image can't be observed the pattern of examination awl, standard pyrometric cone, and it is suitable to be difficult for judging whether to place; 2. video camera and frustum face angle are excessive, have reached more than 20 °, are not easy to whether the observed and recorded examination is bored, standard pyrometric cone is most advanced and sophisticated contacts with frustum.
Application number is 200810230567.2 and 200820149935.6 and is called the patent of " a kind of refractoriness auto testing instrument of horizontal imaging ", it is to be horizontally disposed with a peep hole that connects with the burner hearth test cabinet on body of heater, peep hole is outside equipped with video camera, the awl dish is set in test cabinet, make the awl dish between heater and peep hole, the heater single face heats the cone in the test cabinet; Many cones shape of embarking on journey on same plane is erect and is installed on the strip awl dish, and this plane is vertical with the video camera primary optical axis with the intersection of awl dish upper surface, and camera primary optical axis and awl dish upper surface are at grade; Cone on awl dish and the awl dish is in static state in test process.The deficiency of this kind structure: 1. the awl dish is inserted in the dim rayless burner hearth together with the cone of installing on it, and the display of video camera and display image can't show the pattern of examination awl, standard pyrometric cone during low temperature, and it is suitable to be difficult for judging whether to place; When high temperature, because the high light stimulation of heater can cause that the operator sees giddy when looking into, the observation of cone and record produced interfere, cause technical sophisticationization; 2. only be provided with heater in a side that leaves standstill cone, opposite side is provided with peep hole, and cone leaves standstill, and can not rotate, and single face is heated, and the inequality of must being heated does not meet " GB/T 7322-1997 refractory material refractoriness test method ", lacks scientific; 3. the cone arrangement of embarking on journey, the curved of cone tip deviates from camera towards heater, and the cone tip can be subjected to the coverage or the interference at other positions of cone when bending, camera produces uncertain only along single horizontal direction imaging to accurately catching the contact condition of taking the photograph cone tip and awl dish upper surface; 4. only can catch and take the photograph the most advanced and sophisticated variation of static cone, can not catch the variation at the awl dish upper cone tip of perturbation attitude rotation.
Summary of the invention
