The development of new steel grades is an expensive and time consuming process that could involve multiple laboratory and mill trials. The process parameters that need to be employed can vary greatly from one steel mill to another as a result of the unique configuration of each mill (e.g. number of stands, power, cooling... etc.). Through process modelling has the potential to accelerate the development of new steels and to reduce the development costs by allowing the steel mill to arrive at the final product after a smaller number of trials. The Hot Strip Mill Model (HSMM) software package was released by INTEG Inc. in the year 2000 with the goal of allowing users to create a model that captures the unique configuration of each mill. A key benefit of this software package was the ability to optimize the processing schedule for a specific rolling mill, without exceeding that mill's capabilities (e.g. power or cooling rate). The HSMM, however, required input experimental data on the mechanical properties of the steel and its microstructure evolution. As a result, the model was not suitable for designing new steel grades because a lot of preliminary lab work was needed before the model could be used. This limitation could be addressed through the introduction of physics-based modelling. Over the last 20 years, the McMaster team has developed a series of physics-based models that capture the microstructure evolution of C-Mn and microalloyed steels. The McMaster TMP model was calibrated for several steel grades and is able to predict the microstructure evolution of flow stress for a wide range of compositions and processing conditions. We have demonstrated (proof of concept) the potential to use the TMP model to provide the HSMM with the microstructure evolution and flow stress data that it requires for a new steel grade, thus overcoming a major limitation for using the HSMM for steel and process design. Based on strong positive feedback from industry experts, this proposal seeks to create and test a minimum viable product (integrating the TMP and HSMM), which would then be licensed to a Start-up company, who will sell into this niche market of over 800 hot strip and plate rolling mills worldwide.

新钢级的发展是一个昂贵且耗时的过程，可能涉及多个实验室和磨坊试验。由于每个磨机的唯一配置（例如，支架，电源，动力，冷却等），需要使用的过程参数从一个钢厂到另一个钢厂的差异很大。通过流程建模有可能加速新钢的开发，并通过允许钢厂在少量试验后到达最终产品，从而降低开发成本。 Integ Inc.在2000年发布了Hot Strip Moll型号（HSMM）软件包，其目标是允许用户创建一个捕获每个磨机唯一配置的模型。该软件包的一个关键好处是能够优化特定滚动厂的处理时间表，而无需超过该工厂的功能（例如电源或冷却速率）。但是，HSMM需要有关钢的机械性能及其微结构演变的输入实验数据。结果，该模型不适合设计新的钢等级，因为在使用模型之前需要大量初步的实验室工作。可以通过引入基于物理的建模来解决此限制。在过去的20年中，McMaster团队开发了一系列基于物理的模型，以捕获C-MN和微合同钢的微观结构演化。 MCMASTER TMP模型被校准了几个钢等级，并能够预测各种组成和加工条件的流动应力的微观结构演变。我们已经证明了（概念证明）使用TMP模型为HSMM提供微观结构演化和流动应力数据的潜力，这是新的钢级级别所需的，从而克服了将HSMM用于钢和过程设计的主要限制。根据行业专家的强烈积极反馈，该提案旨在创建和测试最低可行的产品（整合TMP和HSMM），然后将其许可给一家初创公司，该公司将销售到全球800多个热条和板块滚动机的利基市场。
