Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Embodiment of the present invention steel billet temperature on-line acquisition system, as shown in Figure 1, it mainly comprises water tank 1, heat-barrier material 1, heat-barrier material 2 2.2, ceramic fiber blanket 3, steel plate box 4, registering instrument 6, steel plate box 4 and thermopair 11.
As shown in Figure 1, water tank 1 top has vent port 13, and gasification liquid 12 is equipped with in inside, and gasification liquid 12 is generally water, and the most heats that utilize its gasification latent heat that hot environment is imported into are taken away by the vent port 13 of tank top.The outer wall of water tank 1 is coated heat-barrier material 1, the outer wall of heat-barrier material 1 is coated ceramic fiber blanket 3, the periphery of ceramic fiber blanket 3 (surrounding and bottom surface do not comprise end face) is encapsulated by steel plate box 4, forms the body 17(of this system as shown in Figure 5, Figure 6).Because the coefficient of heat conductivity of heat-barrier material is extremely low but maximum temperature that can bear is not high, general 900 ℃ of left and right, and the relative heat-barrier material of ceramic fiber blanket 3 coefficient of heat conductivity is slightly high but maximum temperature that can bear is very high, can reach 1400 ℃ of left and right, can directly be placed in hot environment, so adopt internal layer to coat heat-barrier material, the double-decker of outer coating ceramic tapetum fibrosum, the effect of heat insulation optimum, thereby make that even whole system is long-time uses the registering instrument 6 that also can guarantee in water tank cavity image data safely and reliably under hot environment, and can not burnt.
A cavity 14 is arranged, in order to place registering instrument 6 and filling with insulation material 2 2.2 in water tank 1.In a preferred embodiment of the present invention, as shown in Figure 1, cavity 14 is arranged on a side of water tank 1, between cavity 14 bottoms and water tank 1 inwall, is provided with back-up block 5, and back-up block 5 is in order to support cavity 14.The interior placement registering instrument 6 of cavity 14, after it is started, remainder is filled with heat-barrier material 2 2.2, then with seal pad 9, seals.
As shown in Figure 1, Figure 3, the embodiment of the present invention has connection jaws 10 on the right side of steel plate box 4, thermopair 11 passes successively ceramic fiber blanket 3, passes through seal pad 9, passes heat-barrier material 2 2.2 again to these system ontology 17 inside by connection jaws 10, then with the connection terminal 7 on registering instrument 6, be connected.
As shown in Figure 4, steel plate box 4 both sides are welded with some to nut 15, and steel wire 16 two ends through the center pit of two corresponding nuts 15, then fix respectively, utilize the tension force ceramic fiber blanket that water tank 1 top is coated 3 fixing tight.
Utilize the steel billet temperature on-line acquisition system of above-described embodiment to carry out the method for steel billet temperature online acquisition, its key step comprises:
If S1 steel billet thickness is larger, at first cut out a gap 19 on the steel billet 18 for the treatment of testing temperature, gap 19 sizes should be consistent with the length and width of system ontology 17, the steel billet temperature on-line acquisition system embeds in gap 19, and fix, also can be open and clear mouthfuls 19, and the steel billet temperature on-line acquisition system is directly fixed on to steel billet 18 sidepieces; If steel billet 18 thickness are less, also can be open and clear mouthfuls 19, and directly being fixed on to steel billet 18 tops, the steel billet temperature on-line acquisition system gets final product.Select which kind of mode, can enter heating furnace and be heated smoothly by furnace charge end fire door after being fixed on steel billet 18 to guarantee the steel billet temperature on-line acquisition system, can come out of the stove and be as the criterion by heating furnace discharge end fire door smoothly after completing heating.）
S2, on steel billet, punch, form a plurality of temperature points; In one embodiment of the present of invention, can on steel billet 18, punch to the position that will measure temperature, form the first measuring point 8.1, the second measuring point 8.2, the 3rd measuring point 8.3 and the 4th measuring point 8.4, the four measuring points 8.4 and use for measuring the outside furnace gas temperature of steel billet.
S3, thermopair 11 is inserted on steel billets in each temperature point.
In preferred embodiment of the present invention, between step S2 and S3, can also, at the other welded nut 15 of each measuring point, then this system ontology 17 be embedded in gap 19, and fix.Center pit by thermopair 11 through nut 15, then be inserted in each measuring point on steel billet 18 (the first measuring point 8.1, the second measuring point 8.2, the 3rd measuring point 8.3), in order to the thermopair 11 of measuring the 4th measuring point 8.4 place's temperature, through after the center pit of nut 15, make it can in steel billet 18 heating processes, measure furnace gas temperature upward.
S4, tested steel billet 18 is sent in heating furnace and heated, now registering instrument 6 has started to record the temperature rise data of the first measuring point 8.1 that thermopair 11 gathers, the second measuring point 8.2, the 3rd measuring point 8.3, the 4th measuring point 8.4.
After S5, steel billet 18 heating finish, registering instrument 6 in cavity 14 takes out, then be connected the temperature data that each measuring point (the first measuring point 8.1, the second measuring point 8.2, the 3rd measuring point 8.3, the 4th measuring point 8.4) can be gathered derives with computing machine, then is further processed analysis.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of claims of the present invention.
