“…Second, the initial wall surface temperature of steel plate is higher than 900°C and quenching duration time is longer than 30 min. The micro-heater jet measurement method 24 and temperature oscillation IR thermography (TOIRT) method 25 are not suitable candidates for this situation, high-precision devices and methods with continuous temperature measurement of ultra-heavy plate should be developed. In addition, the difficulties in smelting and rolling of raw materials, as well as the deficiencies in mathematical models and solutions preclude in-depth investigation of heat transfer of ultra-heavy steel plate during quenching process.…”

Large-section ultra-heavy steel plates feature low cooling rate of central part during quenching process, as well as great differences in texture and performance along thickness direction. Wet jet impingement quenching test apparatus and multi-channel temperature recorder were developed to explore the temperature drop characteristics and its influential factors of ultra-heavy steel plate. The temperature drop curves of plates with different thickness (160, 220, and 300 mm) and weight (23–43 tons) were recorded during the quenching process, accompanied with the exploration on distribution rules of temperature gradient, heat flux density and cooling rate along thickness direction under different water volumes (9000–9400 m3/h) and pressures (0.4–0.8 MPa), upon which the three-dimensional inverse heat conduction model, surface heat transfer coefficient model and thermophysical parameter model were established using finite element and optimization methods. The overall results indicate the symmetric heat transfer between the upper and lower plate surfaces can be realized, when the water flow ratios of the upper and lower surfaces were 1:1.25 and 1:1.4 under pressures of 0.8 MPa and 0.4 MPa, respectively. The “temperature return” phenomenon was accompanied with changing heat flux density of wall surface of 220 mm- and 300 mm-thick plates. The lowest cooling rate along thickness direction appeared at 1/4 thickness position for the 160 mm- and 220 mm- thick plates during quenching, which was attributable to the synergy between heat flux density and temperature gradient. This work may pave a way for improving the cooling rate and quenching uniformity of ultra-heavy steel plates along thickness direction.

“…The drawbacks of the test vehicles are the higher cost and the required processing or packaging to be used in the test set-up. These test vehicles can be fabricated using simplified processing of metal heaters and RTDs on Pyrex [30] or full CMOS Si processing. In literature, only a small number of experimental studies using thermal test chips for liquid jet impingement cooling are available.…”
