Description
Technical field
A kind of thermal shock stove of this utility model design and thermal shock resistance experimental provision, a kind of split type thermal shock stove and anti-
Thermal shock resistance experimental provision, belongs to thermal shock resistance experimental provision technical field.
Background technology
Material stands that temperature drastically changes and non-destructive ability is referred to as thermal shock resistance (Thermal Shock
Resistance), also known as thermal-shock resistance or heat stability.
Thermal shock resistance is an important performance of Inorganic Non-metallic Materials (such as: pottery, glass, refractory material etc.).Work as material
Material is heated suddenly (or catching a cold) when expanding (or shrink), and producing heat owing to the deformation of its each several part is restricted mutually should
Power.When this thermal stress exceedes the ultimate strength of material, will produce and burst apart, peel off, rupture and destroy.The resistance to thermal shock of material
Property in addition to being affected by heat transfer conditions, depend primarily on its thermal coefficient of expansion, heat conductivity, fracture toughness, specific heat, intensity etc., with
Time also relevant with its organizational structure, shape and size etc..In order to prevent material in use, destroy because of thermal shocking, it is desirable to
Material has good resistance to heat shocks, therefore in the research process of material, it is often necessary to test its resistance to heat shocks.
The representation of thermal shock resistance and method of testing have a variety of.The anti-thermal shock of material is typically measured with chilling pattern
Property.Conventional expression and test mode have following several:
1. after material rises to different temperature, quenching (air-cooled or water-cooled), record specimen surface and produce the maximum temperature of cracking
Difference.This thermal shock resistance i.e. represented with the temperature difference.
2., after material rises to predetermined temperature, quenching (air-cooled or water-cooled), after completing stipulated number, sample remnants bending resistance is strong
Before degree and room temperature thermal shock, the ratio of bending strength, records strength retention.This thermal shock resistance i.e. weighed with strength retrogression.
3., after material rises to predetermined temperature, quenching (air-cooled or water-cooled), test is until material produces macroscopic cracking repeatedly
Number of times.This thermal shock resistance i.e. weighed with rapid heat cycle cycle-index.
At present, rare for the equipment doing thermal shock resistance experiment specially.Traditional way is: sample is placed on biography
In system high temperature furnace, after being heated to the temperature that experiment needs, fire door is opened manually, taking out one piece one piece of sample from burner hearth,
Put in coolant medium container.Due to unlimited fire door, the temperature in stove reduces, and the temperature of sample also can and then reduce；Take
Also can absorb the heat of sample when material process needs to contact between certain time, and sample with fixture, the temperature of sample can be made to enter
One step reduces, and the temperature difference (high temperature-low temperature) of experiment thus can be made to reduce；For the parallel test of multiple samples, then need repeatedly
Take out sample in turn, so that temperature when coolant medium container put into by sample is different, the temperature of the actual experience of the most each sample
Difference difference；The speed of each experimenter operation is different, and test repeatability is poor.Therefore, the experiment of above-mentioned traditional method gained tie
The accuracy of fruit, comparability, credibility are substantially reduced.
