The Iwatani-Surtec (Rhesca) Hot-Dip Process Simulator (HDPS) provides a realistic simulation of the continuous galvanizing line annealing, gas jet cooling and hot-dip coating processes on a laboratory scale. This is the industry’s first simulator to include the following features, fully integrated into the control system:<br />  </p> <ul> <li>Coating wiping capability with nitrogen, air or other gases</li> <li>Induction and infrared heating</li> <li>Automated humidification of reducing or oxidizing annealing gas</li> <li>Two coating pots, test panel oscillation and usage control of 5 gases</li> </ul> <p>The HDPS provides the capability to develop and evaluate new products and process improvements. It can also assess metallurgical and coating properties for new steels such as automotive advanced high-strength steels up to and over 1180 MPa, highly formable steels with 50% elongation, and smooth galvanneal and galvanized for exposed panels.</p> <p> </p> <p>We support new products and processes development for construction and appliances as well, including new structural steels, new coatings and improvements to GALVALUME® and galvanized. Our HDPS expertise and technology allow ongoing facility process improvements for <span style="white-space: nowrap">U. S.

The HDPS eliminates part of the expense of using production units to conduct trials and allows experiments that could not be conducted at current facilities.</p> <p> </p> <p>Our ULVAC Continuous Annealing Line Simulator (CALS) shares the Simulators Laboratory infrastructure but was custom designed to process larger and stronger panels than the HDPS, which are annealed with a much larger uniformly heat treated area. This high-speed annealing simulator can achieve hotter steel temperatures and can cool panels much more rapidly.</p> <p> </p> <p>Pre-programmed thermal process cycles in the CALS direct precise infrared heating in a sealed gas atmosphere followed by cooling, which may be conducted using rapid gas jet cooling (RJC) or quenched in a temperature and flow-controlled rapid water quench (WQ).</p> <p> </p> <p>A new control system allows faster tuning to closely match the aim thermal cycles requested by product development engineers over the research computer network.

This sophisticated computer system is necessary for the development and physical verification of complicated three-dimensional mathematical models. For example, one such application could be describing the flow of steel through a caster tundish containing various dams and weirs for inclusion removal.</p> <p> </p> <p>This equipment has been used to design fixtures and nozzle systems that have been used for our tundish and strand equipment. The modeling work, which is conducted with both Process Technology and Product Technology engineers, has led to a better understanding of the flow mechanics of liquid metals and improvements in productivity, yield, product quality and facility reliability.</p></p> </div> </div> </div> </div> </div> </section> </div> </div> </div> </div> </div> </section> </div> <div class="portlet-boundary portlet-boundary_com_liferay_journal_content_web_portlet_JournalContentPortlet_ portlet-static portlet-static-end portlet-barebone portlet-journal-content " id="p_p_id_com_liferay_journal_content_web_portlet_JournalContentPortlet_INSTANCE_IfdGQo7Wa7cs_"> <span id="p_com_liferay_journal_content_web_portlet_JournalContentPortlet_INSTANCE_IfdGQo7Wa7cs"></span> <section class="portlet" id="portlet_com_liferay_journal_content_web_portlet_JournalContentPortlet_INSTANCE_IfdGQo7Wa7cs"> <div class="portlet-content"> <div class="autofit-float autofit-row portlet-header"> <div class="autofit-col autofit-col-end"> <div class="autofit-section"> <div class="visible-interaction"> </div> </div> </div> </div> <div class=" portlet-content-container"> <div class="portlet-body"> <div class="" data-fragments-editor-item-id="27701-48881" data-fragments-editor-item-type="fragments-editor-mapped-item" > <div class="journal-content-article " data-analytics-asset-id="32392520" data-analytics-asset-title="About Us Innovation Product Tech Card with White BG Duplicate 1" data-analytics-asset-type="web-content"> <section class="bg-white uss-section text-section"> <div class="container-uss"> <div class="card-employee-innovation-section"> <h6 class="text-secondary-2 text-uppercase heading">PILOT OPERATIONS PROCESSING AND CAN-MAKING FACILITIES</h6> <hr> <div class="row"> <div class="col-lg-4 col-sm-12"> <div class="card-body p-0"> <h5 class="text-primary">Vacuum Melting, Hot Rolling and Forging Laboratory</h5> </div> </div> <div class="col-lg-8 col-sm-12 d-flex flex-wrap"> <div class="card-body p-0"> <p><p>A well-coordinated team of <span style="white-space: nowrap">U.
