Hot rolling allows the material to be shaped in successive steps in different steps since the material is at a temperature above 0.5 Tm which is the recrystallization temperature and gives the possibility of deformation with large deformation rates. In the industry, direct applications show negative effects on time and cost. Practical processes by experimenting can be completed in short periods in some symmetrical profile section products and long periods in some asymmetric profile section products. Finite element method (FEM) can be applied in order to predict the results obtained by simulating the designed calibrations in the computer environment before testing in the rolling mill. In this study, the production of HEA 240 profile in S275JR quality is experimentally made in 21 passes and the geometric dimensions of the first three passes of this structure was compared with 3D FEM analysis results. The comparison results are compatible and high similarity ratio as 95–99.1% was found. Following to this, the analytically calculated dimensions of calibrated IPE 140 profile in S275JR quality was compared by the verified 3D FEM analysis. Considering the first 5 passes of 15 passes for saving time, the simulation and analytical results are in close relationship less than 5% deviation ratio. It is possible to say that this simulation, which has small acceptable differences, has a significant effect on minimizing losses in production processes and achieving production targets.

由于材料处于高于0.5Tm的温度，该温度是再结晶温度，因此热轧使材料能够以不同的步骤在连续的步骤中成形，并且具有以大变形率变形的可能性。在行业中，直接应用会对时间和成本产生负面影响。通过实验的实践过程可以在某些对称型材截面产品中短期内完成，而在某些非对称型材截面产品中长期内完成。可以应用有限元方法（FEM）来预测通过在轧机上进行测试之前在计算机环境中模拟设计的校准而获得的结果。在这个研究中，我们以实验方式在21个焊道中以S275JR质量生产了HEA 240轮廓，并将此结构的前三个焊道的几何尺寸与3D FEM分析结果进行了比较。比较结果是兼容的，相似度很高，为95–99.1％。此后，通过验证的3D FEM分析比较了S275JR质量中校准IPE 140轮廓的解析计算尺寸。考虑到15遍的前5遍可以节省时间，因此模拟和分析结果的紧密关系小于5％的偏差率。可以说，这种可接受的差异很小的模拟对最小化生产过程中的损失和实现生产目标具有重大影响。比较结果是兼容的，相似度很高，为95–99.1％。此后，通过验证的3D FEM分析比较了S275JR质量中校准IPE 140轮廓的解析计算尺寸。考虑到15遍的前5遍可以节省时间，因此模拟和分析结果的紧密关系小于5％的偏差率。可以说，这种可接受的差异很小的模拟对最小化生产过程中的损失和实现生产目标具有重大影响。比较结果是兼容的，相似度很高，为95–99.1％。此后，通过验证的3D FEM分析比较了S275JR质量中校准IPE 140轮廓的解析计算尺寸。考虑到15遍的前5遍可以节省时间，因此模拟和分析结果的紧密关系小于5％的偏差率。可以说，这种可接受的差异很小的模拟对最小化生产过程中的损失和实现生产目标具有重大影响。模拟和分析结果的紧密关系是偏差率小于5％。可以说，这种可接受的差异很小的模拟对最小化生产过程中的损失和实现生产目标具有重大影响。模拟和分析结果的紧密关系是偏差率小于5％。可以说，这种可接受的差异很小的模拟对最小化生产过程中的损失和实现生产目标具有重大影响。
