Product Information

For the inlet and outlet fluid path, holes are drilled perpendicular to the main fluid path and then partially plugged to create a continuous coolant path. Unlike previous cooling technologies, MULPIC has adapted accelerated cooling technologies to include the latest automation and digitalization technologies to realize analog improvements in plate cooling. This solution allows producers of high-strength steel to see immediate improvements in quality and yield while reducing their environmental impact. Additionally, the MULPIC system provides flexibility regarding cooling options, from direct quenching to accelerated cooling, making the cooling process more efficient. MULPIC’s Digital Twin also offers the opportunity to use real-world data in an offline testing format to ensure seamless execution of trial runs and assistance with strategy, product design, development times, and the costs typically associated with such practices. With a combined mechatronic and digital solution, MULPIC offers the opportunity for steel producers to lessen their environmental impact while improving production. Accelerated cooling of hot-rolled sheets emerged in the 1980s. Today, “alloying with water” is standard practice in the steel industry, where micro-alloyed steel plates are cooled directly after rolling, achieving the desired strength, flatness, and toughness. However, the value of accelerated cooling extends beyond the ability to achieve the desired microstructure and product quality but also allows for the elimination of expensive reheating practices, efficient water utilization, improved yield, and an accelerated production time. Brazing in a high vacuum environment provides the most process control and produces the cleanest parts, free of any oxidation or scaling. It is the preferred brazing environment for brazing aerospace components, hardening medical devices and other applications that require the absolute highest part quality. While online operations can experience improvements, offline analysis of aspects of inline cooling improves the function of MULPIC—from heat transfer and metallurgical properties to the impact of the cooling machine. MULPIC’s Digital Twin is a model that utilizes the same models as the Level 2 control system and cooling model that adds a user interface to perform offline simulations. These simulations allow steel producers to optimize the cooling process fully.

By recalculating the required flow at every meter along the plate length, feedforward control compensates for variations in the incoming product temperature. Availability and Maintenance Improvements While the MULPIC system consists of a cooling machine featuring precision valve control and an advanced automation system, a process model, or “digital twin,” allows for the integration of historical data, real-time information, and model adaption to impact the efficiency of continuous operation. The "hot" side is attached to a heat sink so that it remains at ambient temperature, while the cool side goes below room temperature. In special applications, multiple coolers can be cascaded or staged together for lower temperature, but overall efficiency (COP) drops significantly. The maximum COP of any refrigeration cycle is ultimately limited by the difference between the desired (cold side) and ambient (hot side) temperature (the temperature of the heat sink). The higher the temperature difference (delta), the lower the maximum theoretical COP.

Buried Tube Cold Plates

Two unique semiconductors, one n-type and one p-type, are used because they need to have different electron densities. The alternating p & n-type semiconductor pillars are placed thermally in parallel to each other and electrically in series and then joined with a thermally conducting plate on each side, usually ceramic, removing the need for a separate insulator. When a voltage is applied to the free ends of the two semiconductors there is a flow of DC current across the junction of the semiconductors, causing a temperature difference. The side with the cooling plate absorbs heat which is then transported by the semiconductor to the other side of the device. Possibly the simplest form of cold plate where a joint free tube is embedded into a copper or aluminium carrier. When applying plate cooling technology, the benefits for steel producers are abundant, including improved cost efficiency, reduced environmental impact, increased product versatility—i.e., from structural grades to abrasion-resistant steel—, leaner manufacturing, and enhanced quality and productivity. However, previous accelerated cooling technologies were without recent developments in automation and digitalization, which now take each of these improvements one step further. Primetals Technologies has combined its competencies in mechatronics, automation, and digitalization solutions to create the MULPIC system for inline cooling. Direct quenched (DQ) or abrasion-resistant steel plates on a cooling bed Near-surface optical micrograph taken from a test sample of direct quenched (DQ) or abrasion-resistant steel plate Introducing MULPIC A profiled lid is then placed into a recess above the flow-path and is F.S.W (friction stir welded) into place. Finally the welded surface is fly-cut flat, inlet/outlet holes and component mounting holes are added. Die Cast (Liquid cold plate)

A gun-drilled cold plate is manufactured by drilling a series of holes through the length of an aluminium plate to form multiple flow paths. Industry-wide, the use of inline plate cooling technologies has proven to be essential to producing high-strength steel grades. Recently, producers have focused on decreasing their environmental impact and lowering operational costs by reducing post-processing requirements and carefully monitoring and managing water consumption. To this end, the specialists and experts at Primetals Technologies developed the MULPIC system, a comprehensive system for inline plate cooling providing unparalleled control over the plate cooling process. What is inline plate cooling? The next step beyond an open-air environment is to use a controlled atmosphere under normal or close-to-normal atmospheric pressure. In this type of environment, a high degree of control over the overall process can be achieved and open-air issues of oxidation, scaling and carbon buildup can be virtually eliminated. Vaccuum brazing Z T = ( α 2 σ T ) / κ {\displaystyle \mathbb {Z} \mathrm {T} =(\alpha This technology is ideal for prototypes and small production runs as no tooling investment is required.

Tube in Plate (Liquid cold plate)

Each bank includes an independently driven edge masking system on each side of the cooling machine, preventing overcooling which may lead to the poor flatness of the plate following the cooling process. Head and Tail Masking Thermoelectric coolers operate by the Peltier effect (one of three phenomena that make up the thermoelectric effect). [2] A thermoelectric module is made from three components; the conductors, legs, and the substrate, and many of these modules are connected electrically in series, but thermally in parallel. [2] When a DC electric current flows through the device, it brings heat from one side to the other, so that one side gets cooler while the other gets hotter. Previously, hot-rolled plates cooled to room temperature before low-temperature rolling and processing—standard practice for high-strength low alloy steel grades (HSLA). Examples of processing included normalizing and annealing or quenching and temper processing. Before inline plate cooling, steel producers used these steps to tailor the air-cooled plate microstructure for final applications, for example, abrasion-resistant plates. However, with the application of inline cooling, steel producers can achieve target microstructures with temperature control for accelerated cooling and direct quenching. A schematic diagram illustrating post-rolling options with and without inline cooling technology reveals the impact of inline cooling on manufacturing time. Moreover, inline cooling offers various cooling strategies following rolling for different steel grades. Direct Impact of inline Cooling

We apologize for the inconvenience...

Dependent on the required thermal performance and the cooling fluid to be used the tube can be copper or stainless steel and can be a simple mechanical (dry) press fit, press fit with a thermal epoxy boundary to eliminate micro voids or soldered in place for maximum thermal performance. Gun Drilled (Liquid cold plate) The extremities of the product may become overcooled due to additional water flowing across the top surface or from the rolling process itself. During the head and tail (H/T) masking, the water flow reduces by a predefined level and distance along the material to compensate for this additional cooling. Feedforward Control This is a two piece construction. The liquid flow path is CNC machined into the base. This flow-path can be complex and can even incorporate fins to enhance the heat transfer surface.
