Furnace Control System

Controlled Furnace Cool Down Refractory Contraction Control As much attention to the control of temperature levels and distribution must be given when bringing a furnace down for repair as when initially putting it into production, Increasing demands on furnace production inevitably lead to uneven wear of the various types of refractories and the need for partial repairs during the over all life of the furnace. Reversing the heat up procedure and maintaining a steady and controlled cool down after a smooth takeover from the furnace firing system gives the best chance of preserving the integrity of the refractories to be retained. At a temperature around 200 C the burner system is switched off, but the combustion air fan is left running to complete the cooling up to ambient. This process is often accompanied by the HAL Technicians taking control of the furnace contraction during the vital period, and making the necessary adjustment to the refractory retaining steel structure.

HMI gives the ability to the operator, and the management to view the Furnace in real time. Human Machine Interface can display texts, pictures, bar graphs, bitmap and animated pictures. HMI comes with host of Management Information System reports for quick and easy decision making.

Features: Corrosion resistantLonger service lifeSturdily constructed Other information: HIGH POWER (100-350 KW) MEDIUM FREQUENCY FURNACE CONTROL SYSTEMGeneration Next controller is the latest all digital smart medium resonant inverter control system. The controller is built for an AC-DC-AC type of power control providing frequency changing from 50 Hz 4-phase for resonant series converters.The system has analog interface with electrical DC current sensors and potential transformers and an isolated monitor on the DC bus for DC bus short circuits that occur frequently in resonant inverter powered application due to load instabilitiesGeneration Next controller is the latest all digital smart medium frequency series resonant inverter control system. The controller is built for an AC-DC-AC type of power control providing frequency changing form 50 Hz 4-phase for resonant series converters. The system has analog interface with electrical dc current sensors and potential transformers and an isolated monitor on the DC bus for DC bus short circuits that occur frequently in resonant inverter powered application due to load instabilities. It is suitable for application on any power levels up to 400 KW half bridge / full bridge inverter systemsModels available for lower power without AC static switch controller. The front and converter control chip provides high speed AC static switch control facility with high speed interruption within 3.3 ms on 50 Hz systems and soft start on dc bus which can charge into a large DC bus rated capacitance without danger of over currents. A micro-controller assisted text display system monitors all faults external to the system that could be harmful to the equipment. the system is self turned and normalized for analog feedback parameters rated for +/-10 V and so is load independent with proper CT and PT burden calibration on the power site.

Furnace Draft Control System

Furnace Control System A manufacturer of gas turbine components uses vacuum casting furnaces and vacuum heat treat furnaces in their operation. Vacuum furnaces use pumps to maintain an operating pressure less than 10 microns absolute pressure. These pumps are specialized and require extremely rigid control.Induction heaters are required for melting of alloy. Non-contact temperature measurement instruments are required to measure molten alloy temperature.Melting and pouring of molten super-alloy requires interactive, multi-axis motion control.The components produced are subject to lifetime audit. The process must be thoroughly documented during every thermal manufacturing operation. Objective Provide an automatic control system for furnaces used in the casting and heat treat of superalloy.Provide indisputable process documentation throughout component production. Solution Furnace control system includes 480 VAC distribution, instrumentation, inputs and output system, vacuum producing equipment, heating equipment, temperature measuring equipment, safety equipment, and Operator Interface. Sequence of Operation, motion, heaters, and all equipment are controlled by PLC. This control system permits unattended operation of the furnace.Hydraulic servos and electric servo motors move the crucible and the mold ram.Motion control is implemented in a Teach / Playback form. Using custom PLC and PC logic, Operators can manually "teach" the coordinated-axis motion sequence required to properly pour molten alloy into a crucible with a joystick.Certain components require coordinated motion of indefinite length (sometimes lasting several hours). A means of transferring motion profiles between PC and PLC, in real-time, permits Teach and Playback of pours of unlimited duration (limited only by the size of the PC hard drive !)Casting performance is logged to a network database. First generation Operator Interface was developed using Professional Basic. Later generations of this Operator Interface were developed with WonderWare InTouch

Temperature monitoring and control by sensing soaking zone temperature and regulating the air and fuel control valves by means of a PID controller, which can be either pneumatically or electrically actuated. The air : fuel ratio is built into the controller software. One of the noteworthy features of the temperature loop is the special facility provided for manual intervention on occurrence of a mill breakdown, the furnace temperature can be turned down to pre-determined levels simply at the click of a button.
