Automation of Copper Anode Weighing and Casting System, Bor Copper Mine
references in metalsreferences in metals
The customer request was to provide refurbishment of the control system for liquid copper casting “machine”, which is at the end of the copper producing technology chain. Liquid purified copper (98%, after Pierce Smith converters) flows from the anode furnace through ladle mechanism, where the material is weighed. After casting the round cast table automatically turns to the lifting and horizontal transfer system. Mold capacity is 0,5t. In order to produce the anode plates of a particular shape, the allowable weighing fluctuation is ±2%. The whole casting cycle takes 36 sec (filling, weighing, emptying).
 
Scope of Work
Mikro Kontrol provided detailed and as-built design, weighing system reconstruction, drive system reconstruction, MCC and control panel manufacturing (including operator panel), application software, supervision of the electrical works at the site, as well as testing and commissioning.
Benefits
  • State-of-the Art equipment and solution; the old machine was out of work for several years
  • Increasing production capacity and product quality
  • Maximum level of reliability and availability
  • Operation and maintenance convenience
  • The whole project is done within 6 months. It’s successful realization encourages customer to plan the modernization of the second casting machine.
Technical Description
The two DC drives for round cast table positioning are substituted with AC electromotor drives coupled to the same reduction gear and controlled by a “multi-drive” frequency inverter (master – follower mode). Replacement of old AC drives for the copper plate lifting mechanism is done with new AC motor-gear drives, with frequency inverters parameterized for hoisting applications.
Instead of the old weighing system, the new Load cells and measuring amplifiers are installed. The control of the filling and emptying process is realized through proportional hydraulic valves.
The positioning of the round table and it’s movement control are based on absolute encoder and a system of binary sensors mounted on table’s construction.
The control is realized by the PLC in control cabinet in electric room where MCC and LV panels are installed. The PLC is the part of the Smelter and Refinery DCS control network.
Operator control is realized with HMI and control desk mounted at the operator room location.

Aplication Software Development for the Duo HoReCa Napkin Production line, 9. Septembar

references in mechatronicsreferences in mechatronicsMikro Kontrol developed a complete algorithm for control software based on function blocks, application software for safety controller, motion controller and HMI interface, and commissioning with performance test.

Benefits

  • Very reliable, fast and modern control system based on the last generation Omron NJ Motion controller platform
  • Safety protection integrated in safety controller and motion controller
  • Parallel work of transport cars, controlled by the Omron servo drives, contributing to a very large line capacity
  • Complete monitoring and parameter setting of the machine
  • Established fast and efficient communication between all parts of production line

Technical Description

Standard parts of napkin production line include: paper unwinder, printing section, emboser section, longitudinal cutting and perforation, counting and packaging head, transporting part and part for transporting to the packaging machine.

To incerease the line capacity, Mikro Kontrol designed  4 production channels. On every channel, there are 2 pairs of transport cars, driven by 4 servo motors. Internal communication of transportation cars provide very fast and efficient transport without any possibility of collision and accidents.

In addition to many drives controlled by frequency converters, production line includes 24 servo axis capable of very quick and efficient task completion.

In order to avoid channel congestion and capacity decrease, the unloading part of the transport system intermittently moves packages from these 4 channels to an exit chanel on the packaging machine.

Modernization of Two Gantry Cranes 160/50 t, HE PP Djerdap
Mikro Kontrol did a full reconstruction and modernization of two gantry cranes, capacity of 160/50t to support hydro-mechanical equipment in individual work as well as in coupled work.

Scope of Work
Existing wound rotor motors are replaced by corresponding induction motors with squirrel cage rotor. The speed and torque are now regulated by an energy recovery multidrive frequency converter.
Control supervision of each crane is performed by a distributed PLC with appropriate operator panel, located in the operator cab. Coupled work of both cranes encompasses the load distribution in order to equalize the speed of the same drives of each crane.
 
Benefits
  • Reliable work in both single and coupled mode
  • No portal corruption
  • The supervision and control of the load amount of each hook
  • Safety circuit implemented
  • Monitoring alarm system
  • The speed limit in relation to the position and load management driving portal in terms of drive synchronization on both sides
 
Technical Description
Installation of a new cable trolley provided reliable power supplies for energy recovery multidrive frequency converter, located on each crane. Thanks to use of these energy recovery frequency converters Mikro Kontrol increased the energy efficiency of the system.
When in a coupled mode, both PLCs connect with each other through the network by a wireless connection. In this mode one PLC is master and another is slave. This configuration enabled the possibility of a single control point, either a cab or a remote control unit of the master crane.
