F&P Manufacturing Inc., a Tier 1 automotive part manufacturer, is expanding its capabilities to include hot forming/die quenching (HFDQ). In this process, steel sheets, called "blanks," are heating to approximately 1000C, which austentizes the steel and transforms a protective Al-Si coating into a permanent Al-Si-Fe layer that provides long-term corrosion protection. The hot blanks are then transferred to a cooled die, where they are simultaneously quenched and formed into shape. Almost all hot stamping lines heat the blanks with roller hearth furnaces. This technique has several shortcomings, however, which has motivated F&P to pursue an alternative technique in which blanks are heated by bringing them into contact with a hot surface. This approach would require significantly less floor space and consume far less energy compared to roller hearth furnaces, and could also produce parts having tailored microstructures through controlled, non-uniform heating. Preliminary research carried out by the University of Waterloo and F&P resulted in a lab-scale prototype that demonstrated the feasibility of this approach. The objectives of the proposed research are to develop a pilot-scale apparatus that combines direct contact heating and forming on a single hydraulic press. This process will eliminate the need for roller hearth furnaces, thereby realizing dramatic reductions in capital and operating costs, and improvements in process efficiency. Moreover, the highly-controlled blank heating realized through this process will facilitate tailoring and improve part quality. These improvements will give F&P a crucial advantage over international competitors. Reduced costs and improved part quality will also benefit F&P's customers, and exemplifies the innovation needed to ensure the ongoing viability of Canada's automotive sector. Finally, this research will equip two highly qualified personnel with skills in engineering design, manufacturing, and experimentation, which are all in demand by Canadian industry.

F&P Manufacturing Inc.作为一家一级汽车零部件制造商，正在扩大其能力，包括热成形/模具淬火（HFDQ）。在这个过程中，被称为“坯件”的钢板被加热到大约1000 ℃，这使钢凝固，并将保护性Al-Si涂层转化为永久性Al-Si-Fe层，提供长期的腐蚀保护。然后将热坯料转移到冷却的模具中，在那里它们同时淬火并成形。 几乎所有的热冲压生产线都使用辊底炉对坯件进行加热。然而，这种技术有几个缺点，这促使F&P寻求一种替代技术，其中通过使坯料与热表面接触来加热坯料。与辊底炉相比，这种方法需要的占地面积明显更少，消耗的能量也少得多，并且还可以通过受控的非均匀加热来生产具有定制微观结构的部件。滑铁卢大学和F&P进行的初步研究产生了实验室规模的原型，证明了这种方法的可行性。 拟议的研究的目标是开发一个中试规模的设备，结合直接接触加热和形成一个单一的液压机。该工艺将消除对辊底炉的需要，从而实现资本和操作成本的显著降低，以及工艺效率的提高。此外，通过该工艺实现的高度受控的坯料加热将有助于定制并提高零件质量。这些改进将使F&P相对于国际竞争对手具有至关重要的优势。降低成本和提高零件质量也将使F&P的客户受益，并加强确保加拿大汽车行业持续生存所需的创新。最后，这项研究将配备两个高素质的人才与技能的工程设计，制造和实验，这都是在加拿大工业的需求。
