Comparison of the temperature distribution and flow pattern between the conventional system or full speed and the new system with the inverter by changing speed of outflow has been made. A three-dimensional model of the transient heat transfer has been developed and validated against the real data. In this work, temperature distribution and flow pattern of gas mixture between air and solvent have been studied. To handle this, an inverter has been implemented to provide saving of electricity bill. This leads to the temperature decreasing at the drying zone of the thermal drying oven, especially to unloading. At the thermal drying oven, exhaust gas is delivered out by the blower to eliminate the solvent. Metal sheets have to be coated with food grade lacquer and dried at thermal drying oven for metal can making process. Paisan Kittisupakorn, Patsarawan Lipikanjanakul, in Computer Aided Chemical Engineering, 2015 Abstract In conclusion, metal sheets are an ideal product for many types of uses and installations, or any use that you can think of, thanks to the versatility of it.12th International Symposium on Process Systems Engineering and 25th European Symposium on Computer Aided Process Engineering All this will depend on the environment in which it is placed, since the more humid or corrosive it is, the less time will elapse until maintenance is necessary to prevent rust from appearing and affect the integrity and resistance of it. Are there materials that are cheaper? Also, but they will support less weight.Īs we mentioned when we explained the advantages of maintenance, thanks to the grating galvanizing, it can have more than 20 years lifetime. Are there materials that support more weight? Yes, but they will be more expensive. The advantage of the grating at this point lies in the resistance of this product in relation to its cost and weight/m2. As we have said before, the predominant use of metal sheets is industry, and in most cases the grating has to withstand a certain weight, whether it is people who transit the same, vehicles, machinery or palletized merchandise. We can´t stop talking about another advantage such as resistance. A metal sheet exposed to hot-dip galvanizing treatment, can be placed for more than 20 years without any maintenance action, except to check that the fasteners are tight or repair any damage that has been caused by external factors. In most cases this will consist of placing the grating on the supports (correctly to support the load to which it will be subjected) and optionally fix it with fastening parts to reduce vibration and movement in the same.Īnother advantage is its maintenance, or better said, the absence of it. We can start with its installation, which is very simple unless you decide to manufacture excessively large modules or the place where it will be placed is difficult to access. But perhaps the right question is: What advantages do I get when buying a steel grating compared to other products/materials? Its an obvious answer: because you need it and when you need it. The most common applications would be the following: Walkways, stairs, gutters, shelves, fences, tree guards and false ceilings, among others. At other times, using only the word grid or grating can also be a somewhat ambiguous definition, since for example we call the grill the utensil where the meat is put on a barbecue (although it may be more correct to call it grill) and to the plate that is used for kitchen ventilation and little have to do with those grids with an electrowelded or manual grating that can be used in a platform or for passing vehicles.Īlthough the predominant application of metal grating is in industry, it is a very versatile product and thanks to this it is possible to apply it in various areas, from a fencing to paperweight, which would also fulfill its function (if we think of unusual uses). Sometimes it can lead to misunderstanding, as it happens with metal mesh, which can be confused with electrowelded mesh (commonly used for enclosures), being a product quite different from the steel grating. Perhaps the most common word to name it is grating, followed by “tramex”, but it can also be called in many other ways: metal grating, metal lattice, tramex plates, stainless steel grating, metal grills, etc.

Depending on the nature of the junction in the knots the type of grating is determined: electrowelded grating, pressed grating or manual grating. The points of union between the two types of profiles are defined as nodes. What is a metal sheet? Toni Marín Trillo - Ī metal sheet, as we have explained in other posts, is a reticular structure formed by supporting plates joined orthogonally by transverse elements.
