Abstract
The invention, belonging to mechanical device used for heating the high temperature fatigue sample, relates the three-stage split type fatigue high temperature furnace. The ring insulating brick is installed on the inner wall to form heating cavity. The up and down furnaces have the holes used for sample head restraint crossing. The furnace filament is divided into upper segment, middle segment, and lower segment which are buried in insulating brick and connected by contact point of contact point and controlled by temperature controller and collected temperature by heat electric couple. Due to adopt three stages to control temperature, the invention possesses the advantages of nicety, convenience, high heating rate, homogeneous heating, improving the service life of furnace filament and reducing experimentation cost.
Description
Technical field
The invention belongs to the mechanism of high temperature fatigue sample heating usefulness, be specially a kind of three sections opposite opened fatigue and high temperature all-in-one ovens.
Background technology
Domestic and international various experiment process furnace present generally adopts the high-temperature electric resistance furnace silk that sample is heated, but in today of development in Hi-Tech, to the performance index of various materials require more and more higher more and more smart.Such process furnace can not satisfy the needs of accurate high temperature fatigue experiment, sample is in heat, also to do fatigue test, therefore the body of heater upper and lower surface hole that must have the sample chuck to probe into, even sealing is good again, still have heat to shed at this two place, can make the temperature everywhere in the stove inconsistent, its two, the stove silk exposes in the air of furnace chamber, sample obviously is higher than the temperature at other position near the temperature at stove silk position, cause sample temperature everywhere inconsistent, in addition, the High Temperature Furnaces Heating Apparatus silk exposes in air, easily oxidized and scrap, reduce work-ing life.
Summary of the invention
The object of the present invention is to provide a kind of interior temperature of stove that can make even, to the sample even heating, and can improve the high-temperature heating equipment in the work-ing life of stove silk, i.e. three sections opposite opened fatigue and high temperature all-in-one ovens, its purpose is to improve the level of fatique testing at elevated temperature in the laboratory.
Technical scheme of the present invention is:
A kind of three sections opposite opened fatigue and high temperature all-in-one ovens, it is characterized in that: body of heater is two portions opposite opened structure, the inwall of each part shell of body of heater is equipped with annular insulating brick, form heating chamber by annular insulating brick, on the body of heater, have the hole of passing for the sample dop down, electric stove wire is divided into, in, following three sections, be embedded on the insulating brick respectively, in, following three parts, every section electric stove wire links to each other by the point of contact of being located at the insulating brick surface, be provided with in the body of heater, in, following three thermopairs, every section electric stove wire is controlled heating and is gathered temperature in the body of heater by thermopair by temperature controller respectively.
Described body of heater is upper and lower to be equipped with insulating cotton with inside and outside surface sample dop junction.
Described opposite opened body of heater two portions connect by rotating shaft, and folding around the shaft, and when closed, two portions are locked by locking mechanism.The invention has the beneficial effects as follows:
Three sections temperature controls of the present invention are more accurate, convenient, rate of heating is fast, can make that temperature evenly rises in the stove, can make the sample thermally equivalent, and can accurately gather temperature in the stove, stove silk, body of heater are integrated, in the work-ing life of having improved the stove silk, have reduced experimentation cost.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a control section schematic diagram of the present invention.
Embodiment
Shown in Fig. 1-2, three sections opposite opened fatigue and high temperature all-in-one ovens, body of heater is two portions opposite opened structure, the inwall of each part shell 1 of body of heater is equipped with annular insulating brick 9, electric stove wire is divided into, in, following three sections, be embedded in respectively on the insulating brick 9, in, following three parts, every section electric stove wire 5 is by continuous (the point of contact a of the point of contact of being located at insulating brick 9 surfaces, b, c respectively with a ', b ', c ' links to each other), be provided with in the body of heater, in, following three thermopairs 7, every section electric stove wire is respectively by electric stove wire the other end d, d ', e, e ', f, f ' links to each other with separately temperature controller, is controlled heating and is gathered temperature in the bodies of heater by thermopair 7 by temperature controller.The upper and lower surface of described body of heater has the hole of matching with the dop 2 of sample 4, and body of heater is upper and lower to be equipped with insulating cotton 3 with inside and outside surface sample dop junction; In described opposite opened body of heater two portions, a part is fixing, and another part is connected with fixed part by rotating shaft 8, and folding around the shaft, and when closed, two portions are by Movable loop 6 lockings.
As shown in Figure 2, the structure of High Temperature Furnaces Heating Apparatus of the present invention is a three-stage heating furnace, body of heater upper, middle and lower three parts, control heating and collecting temperature by three temperature controllers respectively, this has not only improved the rate of heating of sample in the furnace chamber, also avoided causing temperature inequality in the body of heater owing to the heat radiation of two holes up and down of body of heater, and can accurately gather the temperature of different positions in the body of heater, upper and lower stove silk plays the effect of temperature compensation.
The stove silk of high temperature furnace of the present invention is embedded in the body of heater, and stove silk and body of heater are reached integrated, can make stove like this Temperature in the chamber evenly rises, and avoids the too high phenomenon of local temperature; In addition, after stove silk, body of heater are integrated, The stove silk is not exposed in the air, has avoided the defective of high-temperature oxydation, has improved the service life of stove silk.
