【摘要】：冷卻輥溫度是影響非晶帶材質(zhì)量的關(guān)鍵因素,為此應(yīng)用流體動(dòng)力學(xué)軟件FLUENT模擬了冷卻輥外壁面沿圓周方向的熱流分布,以此為邊界條件,采用有限元分析法對(duì)冷卻輥進(jìn)行了穩(wěn)態(tài)溫度場(chǎng)分析,獲得了冷卻輥內(nèi)外壁溫度場(chǎng)分布,討論了冷卻輥輥厚和冷卻水通道高度對(duì)冷卻輥溫度場(chǎng)的影響規(guī)律。結(jié)果表明:減小冷卻輥厚度可降低冷卻輥外表面溫度,提高內(nèi)表面溫度;減小冷卻水通道高度可以降低冷卻輥內(nèi)外表面溫度。通過(guò)綜合分析,得到冷卻輥內(nèi)外表面溫度在一定范圍內(nèi)的最優(yōu)化設(shè)計(jì)方案,為非晶帶材冷卻輥的設(shè)計(jì)及優(yōu)化提供理論支持。
[Abstract]:The temperature of cooling roll is the key factor affecting the quality of amorphous strip. In this paper, the heat flux distribution of the outer wall of the cooling roll along the circumferential direction is simulated by using the hydrodynamic software FLUENT, which is taken as the boundary condition. The steady-state temperature field of cooling roller was analyzed by finite element method, and the distribution of temperature field inside and outside the cooling roll was obtained. The influence of cooling roll thickness and cooling water channel height on the cooling roll temperature field is discussed. The results show that reducing the cooling roll thickness can reduce the outer surface temperature of the cooling roll and increase the inner surface temperature. The inner and outer surface temperature of cooling roll can be reduced by reducing the height of cooling water channel. Through comprehensive analysis, the optimum design scheme of inner and outer surface temperature of cooling roll is obtained, which provides theoretical support for the design and optimization of amorphous strip cooling roll.
