A typical hot scarfing machine package as supplied by L-TEC includes not only the machine itself and its related auxiliary assemblies, but also the benefit of our more than 75 years of successful experience to assist in planning, commissioning and maintaining the equipment. All machines and equipment are ruggedly built to withstand severe operating conditions and ensure dependable service.
L-TEC’s hot scarfing machines are remotely controlled, "pass-through" type machines. They are designed for mounting on rails transverse to the roll table and can be retracted from the production line by the operator to facilitate servicing the machine. Generally, it is recommended that they be used for scarfing semi finished steel sections not less than 5 meters (16.4 feet) long: this minimizes the number of starts required, conserves gas, and makes high production rates possible. The mill provides smoke cleaning and slag removal facilities required for production operation.
All L-TEC scarfing machines for hot scarfing feature high-pressure water jets, which efficiently remove and granulate the scarfing slag from the steel surfaces. Many additional proprietary features are standard in these versatile machines such as: self-sizing, automatic oxygen and fuel gas valving, and EPC control system (for more information on EPC control, click here). Many customer specific options are also available with all of our Hot Scarfing Machines; including heavy corner removal, HMI (Human Machine Interface) – PLC systems that can communicate with level 1, 2, & 3 computer systems, near-end start, or end start scarfing units, and our patented smooth surface finish [patent no. 6,174,491] (for more information on smooth surface preheat blocks, click here).
