Adding the CP calculation option to the advanced UT75A Digital Indicating Controller enables CP (Carbon Potential) control. CP calculation can be carried out with just one line of a UT75A ladder program.

Steam is still one of the most popular methods of providing an energy source to a process and its associated operations. The more accurate and reliable measurements that are made, the more informed decisions can be taken that affect costs and product quality.

One of the most common applications for differential pressure transmitters is flow measurement. DPharp differential pressure transmitters have some unique signal conditioning features to eliminate instability at low flow rates.

O₂ measurement is used to safely recover flue gas containing a high concentration of CO from a converter furnace. With conventional paramagnetic oxygen analyzers, O₂ concentrations are obtained through a sampling system to recovery flue gas. Therefore, there are problems with the maintenance and running costs of the sampling system, and time delays in measurement.

With its carbon potential (CP) value calculation function, the CX1000/CX2000 can be applied to a wide variety of applications involving atmospheric gas carburization, and offers a simple, high costperformance solution for improving quality and efficiency.

This paper introduces the ADMAG AXR 2-wire magnetic flomwmeter solution for dust collection water application of steel converter.

When cracks proliferate in the fire-resistant bricks used in a coke oven's combustion chamber, exhaust gases leak into the flue and the dust concentration increases there. By continuously measuring the dust concentration with DT450, emissions to the atmosphere can be controlled.

In pulverized coal injection systems used by the iron and steel industry, a bag filter separates pulverized coal from hot air. The pulverized coal is then conveyed to a storage tank and the hot air is discharged to the atmosphere. If the bag filter breaks, pulverized coal leaks out into the atmosphere.

To detect air leaks, an oxygen analyzer is used. The ZR22/ZR402 Direct In-Situ Zirconia Oxygen Analyzer has been well received due to its good response speed, stability, and maintainability.

In a hot blast stove, the by-product gas produced in a coke oven is burned to preheat the air blast for the blast furnace. To improve the combustion efficiency and conserve energy in a hot blast stove, it is essential to be able to control combustion by measuring and adjusting the oxygen concentration in the exhaust gases.

A furnace for heating slabs needs to be operated under low oxygen conditions at high temperatures of 1000°C and above to prevent oxidation of the steel. The measurement of oxygen concentrations in the furnace is essential in this process.

The discharge of improperly treated industrial chemicals and fuel gas can have a major impact on the environment, posing a serious threat to public health. Concurrent with the global growth of manufacturing operations to keep pace with market trends, many countries are taking measures to deal with environmental problems.

This paper introduces the ADMAG AXR 2-wire magnetic flomwmeter solution for chilled water application in air conditioning unit.

A belt conveyor fire detection solution employing the DTSX distributed optical fiber temperature sensor can greatly reduce crises that can threaten a company's survival.

To technology in iron & steel industry is continuously improved to obtain the best possible performance. The improved plant performance gives rise to the higher quality improvement and lower cost, and simultaneously environmental friendly plant operation.

Many messages can be output even with a limited number of remote inputs by combining the remote input, computation, alarm, and event action functions. 

In order to save energy and reduce rounds made for periodic inspections, you can set up acquisition and monitoring of power data and temperature data from converters, alarms warning against imminent shutoffs due to power overages, abnormal temperature alarms, and other mechanisms.

One important risk to manage with regard to coal stacks is preventing fires due to spontaneous combustion.

Employ the ISA100.11a-compliant YTMX580 Multipoint Wireless Transmitter. The YTMX580 has 8 channels of universal input, which is perfect for multipoint measurement applications, and it can withstand harsh operating temperatures of -40 to 85 °C.

Direct Reduction Iron (DRI) is one of the processes to reduce oxygen from iron oxide pellets for steel plant. More than 90% of DRI processes use heated LNG as process gas where PID control for temperature or interlock control is of vital importance.

Customer needed efficiency improvement of steel manufacturing by temperature monitoring for heat/cooling equipment. Previous system required periodic compensation lead changing.

An induction furnace melts metal by creating very large currents in the material. These currents are induced using three electrodes positioned inside the furnace. The furnace is automated so that once the material has been melted, the electrodes are removed and the furnace then tips the molten metal into a crucible where it can be easily transferred to the production line where it will be cast into ingots. The atmosphere is extremely aggressive and the wired infrastructure is both expensive and very unreliable to maintain. The furnace control requires a total of 20 measurement points distributed around and inside the furnace. The harmonic field effects caused by short circuit 40,000 A (300V). The causes significant interference.

The worlds of process automation and production management have been converging for some time. What once used to be islands of automation and production management functionality connected through highly proprietary integration schemes that were costly to maintain have developed into integrated platforms that provide seamless data exchange between the world of automation and the plant floor, the functions of production and operations management, and integration with business level systems.

The world of process automation is governed by procedures. While we like to refer to the process industries as being largely "continuous", this could not be further from the truth. Process manufacturing is constantly in flux.

The automation suppliers that will be successful in the long term will be those that effectively address application or industry specific problems for end users with a value proposition that cannot be ignored. These problems exist throughout the process industries today, and they won't be solved by simply offering a product, but through a combination of hardware, software, services, application expertise, and knowledge.

In ARC's view, customers need a compelling business value proposition to justify investment in any kind of automation. Vigilance and VigilantPlant were created with this in mind. Yokogawa's vision with VigilantPlant is to create an environment where plant personnel and operators are well informed, alert, and ready to take action. 

Yokogawa has come a long way in making its message clear to the world of process automation. Last year, the company embarked on a full-scale global marketing campaign to make customers aware of the company's focus on system reliability, security, dependability, and robustness. Dubbed "Vigilance", the campaign created a unified message for the company and greatly helped expand awareness of the Yokogawa brand and corporate philosophy.

Process automation end users are under more pressure than ever to do more with less. The current economic climate means that many automation capital projects are on hold. With capital budgets tighter than ever, users instead focus on operational budgets (where cost cutting is also a key concern), or on automation investments with a very rapid return on investment.

In today's dynamic industrial marketplace, the only constant is change. Raw material costs, energy costs, market demands, environmental and safety regulations, technology, and even the nature of the labor force itself are constantly changing, and not always in predictable directions.

Honeywell and Yokogawa have both been producing Distributed Control System (DCS) platforms for decades, and both are very active in this area. In 1975, Honeywell introduced its TDC2000 platform and Yokogawa brought out CENTUM. These two competing systems emerged from a similar place, oil refining and petrochemical industries, so they started out with similar basic concepts and use cases in mind.
