Product Information

The impact of accelerated cooling on plate production is immediately visible regarding reduced manufacturing time. For example, direct quenched (DQ) or abrasion-resistant steel plates require specific processing that traditionally utilizes reheating, quenching, and tempering to reach the necessary hardness, toughness, work-hardening, and ductility required. Producers of high-strength steel focus on these characteristics because abrasion-resistant steel is essential in mining, lifting, and excavation industries. Inline cooling technology is a viable solution for steel producers to achieve greater efficiency by applying direct quenching that bypasses the reheating step. This technology is ideal for prototypes and small production runs as no tooling investment is required. Each top header contains three chambers, with the flow controlled by a crown valve. The water flow density is uniform across the width of the fully open valves. As the valves are closed, the water flow to the end chambers lessens, and a water crown forms. One should note that crown control increases in importance as the plate width increases.

Columbia-Staver are the go to experts in liquid cooling and offer a comprehensive range of cold plate technologies such as, Serpentine (tube in plate) designs, gun drilled, and multi piece designs that can have enhanced surface areas included in the liquid path. Columbia-Staver can select the joining method of a multi-piece design to suit the design and volume required. Columbia-Staver can also offer FSW (Friction Stir Welded) cold plates, Vacuum Brazed and Dip Brazed. These cold plates are generally used for high-performance designs that require low thermal resistance, and superior leak-free reliability. They enable designers the greatest flexibility in specifying such criteria as thermal resistance, thermal flow, pressure drop, fluid path, size, shape, material hardness, surface geometry, and the ability to mount components on both sides of the plate. The internal features can be created by machining flow guides and fins from the base metal or by introducing high-performance corrugated aluminium-fin.

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? Multiple internal and external features can be incorporated into the two Die Cast tools. After casting the two halves can be bonded together by welding or by the use of an epoxy. Brazed (Liquid cold plate)

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) 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. Z T = ( α 2 σ T ) / κ {\displaystyle \mathbb {Z} \mathrm {T} =(\alpha 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. Thermoelectric cooling uses the Peltier effect to create a heat flux at the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current. Such an instrument is also called a Peltier device, Peltier heat pump, solid state refrigerator, or thermoelectric cooler ( TEC) and occasionally a thermoelectric battery. It can be used either for heating or for cooling, [1] although in practice the main application is cooling. It can also be used as a temperature controller that either heats or cools.

Cold Plate Features & Benefits

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 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. 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 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. Each manufacturing technique has advantages depending on the liquid cold plate design, the manufacturing volume required, the choice of cooling liquid, pressure drop requirements and the financial budget of the customer.
