Laser system for dry pretreatment.
A back-coated fabric should be pre-treated with a laser system. The feed of roll (width of the goods: 70 cm) should be automatic. The existing winder has a motor, which must be controlled by the laser system. A mechanical system must be installed in the plant, which guarantees a defined service voltage. The laser-assisted drying pre-treatment consists mainly of the components radiation source, cooling unit, scanner / scanning system, suction with recirculated air filter, software / computerized system, conveyor mechanism of roller, a cross cutting unit at the end of the plant and the machine housing with appropriate safety technology and automated control to reach the Laser class 1 in normal operation. The OPC-UA protocol will serve as a mandatory interface within a demolinia.
The laser system is intended to provide a high variability of the laser parameters (eg, power, pulse frequency, pulse duration, focus position, traverse speed, line spacing, etc.) in order to achieve the desired surface effects for the particular textile. For the investigation of the properties under exclusion of oxygen, a connection for a process gas (nitrogen), which shields the area of the laser, is required. At the end of the drying pretreatment, the textile is cut by means of a cross-cutting device into pieces which are approximately 700 mm (L) long, which are to be transferred via an oblique plane to a storage system. The textile used has a thickness of 5 mm at the current planning level. The required cross-cutting device should, however, be able to cut a thickness of up to 20 mm in a perspective manner.
Subsequently, the pretreated textile pieces are removed by means of a robotic system for textile processing.
For current and planned research projects, a tunable femtosecond (fs) laser system consisting of an fs laser, two optical parametric amplifiers (OPA) and a delay line has to be procured.
A laser cladding system (laser application welding system) is used for the processing of specially manufactured metallic powder systems. This plant is to have all the necessary modern industrial laser welding systems that are suited to industrial conditions. The power class of the beam source (diode laser) must be at least 4000 W. For the manipulation of the laser head, it is possible to integrate a robot of the KUKA brand provided by the Technical University of Chemnitz into the plant concept or into the plant control system. The laser system has to be technically integrated into the existing HVOF spraying system of the company GTV with regard to the welding smoke extraction.
Cleaning services to industrial and waste water installations at the site Ronneburg.
Cleaning of stripping columns, thickeners, basins, manholes, pipes, tanks, chambers, pumping stations, water intakes, pipes and gutter cleaning and TV exploratory and Leak and pressure tests with regular cycles and upon request.
Framework agreement on maintenance services for KSB pump assemblies and required fittings as well as delivery of spare parts at the Ronneburg site of Wismut GmbH.
64 pcs. Pumps in the water supply, water supply, water supply, water treatment plant (WBA) and industrial settling plant (IAA) - Pump types see contract documents.
For ongoing and planned research and industrial projects, a high-pressure system with water inpressure technology (WIT) and a corresponding control and regulation unit with integrated vacuum technology and the appropriate containers for emptying and cleaning the component structure for the production of new light-weight structures are to be procured by injection molding and compression molding. The plant must also be equipped with the TIK-WIT process in order to broaden the application and application spectrum for component production.
The city of Chemnitz is planning to build a fire Technical Centre in Stelzendorf in the industrial area at the Carl-von-Bach street in Chemnitz.
The development includes three building sections: a fire technical center, an exercise room and a training tower. Furthermore, a training center with various training areas are available.
The planned building part Fire Department Technical Center consists of a central three-storey structure in massive construction and two orthogonally arranged wings as a lightweight construction hall. The building is located in different levels due to the terrain situation.
The Fire Department Technical Center will include the following usages include: maintenance hangar for vehicles Fahrzeugabstellhallen, rooms for staff, locker, plumbing and technology. Furthermore, workshop areas with a central assumption, an administrative area and a computer and radio workshop and a central training room for 80 people are provided.
The planned in a steel structure exercise hall should be accessible and serves the purpose of performing exercises with vehicles.
The drill tower is built in massive construction as reinforced concrete structure.
