High power cold circular sawing plants

MFL claims to be the only manufacturer that produces layer-sawing machines up to this large layer width of 1.5m. Thereby, MFL offers completely new technology for rolling mills by cutting big profiles with carbide tipped saw blades. A complete sawing machine includes auxiliary equipment in the inlet and outlet stand-alone sawing machine. In addition, when compared to conventional friction saws, there are a number of advantages to the new technology for cutting structural steel with carbide tipped saw blades. Qualitative advantages of the final product include a smooth cutting surface, which is almost burr free. In addition, there is the benefit of a 100 per cent rectangular cut in horizontal and vertical direction. Operational advantages include a noise level of less than 92dbA, no dirt and spark pollution during operation, and an increase of lifetime to a minimum of 150 to 200 per cent.

Maschinenfabrik Liezen und Gießerei GmbH (MFL), Austria, is a leading manufacturer of high power cold circular sawing plants. The sawing plants are designed for cutting of construction and stainless steel, ferrous and non-ferrous material in the form of billets, tubes, profiles and plates.

can operate with 38-287rpm. The automatic programmable bar stop ensures precision, even when quickly changing cutting measures. A patented discharge system allows fast unloading of cut pieces and maintains the correct position of the material after the cut. This makes it easier to attach the machine to other working units. Pedrazzoli’s IMS control (intelligent motion system) allows the feeding speed, thrust These custom-made solutions are used for specific applications such as tube or profile layers, billets or plate sawing plants. Billets and tubes up to 800mm in diameter can be cut by the company’s billet and single tube sawing machines. Each of these machines utilises carbide tipped saw blades, which guarantee an accurate and high capacity by lower cost and long tool life. MFL has developed a layer sawing machine with a layer width of 1.5m that can be used for cutting tubes, I- and U-beams, sheet pilings, angles and profiles. This special sawing machine (type HKA 2200 L160) has been installed at a Chinese company that produces construction steel profiles. The MFL sawing machine is used for the cutting of several profiles in one layer to the required exact length. This sawing machine is equipped with an installed driving power of 160kW and a saw blade diameter of 2,200mm. The fully automatic sawing machine was supplied and installed in 2007.
