新型铸钢冷却壁的传热学数值模拟

Numerical Simulation Based on Heat Transmission of the Cast-Steel Cooling Stave of New Structure

采用数值模拟的方法对新型铸钢冷却壁稳态温度场进行了数值模拟。计算结果表明:新型铸钢冷却壁肋板基本磨损后的炉役期内,即使在渣皮刚脱落时,其热面峰值温度值也在安全温度范围内;当热面粘结渣皮厚度为10 mm时,其热面最高温度值只比铜冷却壁高28℃,并且渣皮愈厚相差愈小,趋于相同。

The steady temperature field of the new cooling Stave of cast steel is numerically simulated. The result shows that the maximum temperature of its hot-side, within the service life that fins disappear, is still in the safe range even if the slag on hot side breaks off. And the temperature is merely 28℃ higher than copper cooling stave＇s when slag of 10 mm thickness is attached to each of them. The temperature difference between them becomes less when the thickness of slag gets thicker, and eventually tiny.
