internal cooling hot design work roll mill

2.972 How A Compression Refrigeration System Works

work = h 4 – h 3. From stage 4 to stage 1, heat is given off through the condenser, thus. q out = h 4 – h 1. The coefficient of performance describes the efficiency the evaporator to absorb heat in relation to the work put in, thus. b = refrigeration effect / work input = q in / work = (h 3 – h 1) / (h 4 – h 3).

Rolling (metalworking)

Roll stands holding pairs of rolls are grouped together into rolling mills that can quickly process metal, typically steel, into products such as structural steel (I-beams, angle stock, channel stock), bar stock, and rails. Most steel mills have rolling mill divisions that convert the semi-finished casting products into finished products.

Air Cooling vs. Liquid Cooling

In comparison to air, liquid cooling is 2-10 times more effective in transporting heat away from a source to a secondary cooling surface, where the ratio depends on the way it is utilized. An ideal coolant has a high thermal capacity, low viscosity, and low cost, and should be non-toxic and chemically inert (not causing corrosion in the cooling system).

Heat removed from one medium is transferred to another medium, or process fluid. Most often, the cooling medium is water. However, the heat transfer concepts and calculations discussed in this chapter can also be applied to other fluids.
