作者： M. Henze R. Mol M. Pelkkikanga Process and Production Control Systems ASEA Metallurgy S-721 83 Västeras Sweden ESTS BV Hoogovens Groap IJmuiden The Netherlands Rautaruuhki Oy Hämeenlinna Works Hämeenlinna Finland

This article deals with the revamping of a tandem cold strip mill at RAUTARUUKKI OY, Hameenlinna Works, Finland. The article describes how the introduction of a computer based Production and process control System to the existing mill drive equipment achieved: Increased production Increased strip product quality Improved operators working environment and safety The revamping was executed in two stages: Revamp stage 1 required 4 weeks shut down and resulted in fully automatic rolling. Revamp stage 2 required no shut down and gave further improved yield and quality. The results achieved are: Time Capacity Number of operators Thickness tolerances Off-gauge strip length Before revamp 100% 8 ± 3,0% 45m After revamp 1 120% 7 ± 2,0% 30m After revamp 2 135% 6 ± 1,5% 20m A similar revamping is now being made at the 5-stand mill at SVENSKT STÅL SSAB, Borlänge in Sweden and is applicable to any tandem cold mill suffering from poor efficiency.

Plant/operations progress 1983年第3期2卷 182-184页

作者： Kenson, Robert E. Met-Pro Corp. Harleysville Pa. 19438 He has over fifteen years' experience in chemical process engineering including petrochemicals fertilizers synfuels energy recovery and polution control processes. In his present position he is responsible for all research/development design and project management activities in pollution control and energy/resource conservation systems for Met-Pro's Systems Division. The author of numerous publications he has presented papers before national meetings of WWEMA APCA AIChE Catalysis Society ACS and AIChE. Ph.D. from Purdue University and an AB from Boston University. He is a member of AIChE APCA AMA and Sigma Xi. As a member of AIChE he has been active as session chairman national program coordinator programming committee member and task force member for the Environmental Division.

The article demonstrates that catalytic incineration is often economically attractive as an alternative to thermal incineration for petroleum and petrochemical process organic emissions. Even where the initial cost of the catalytic incinerator is greater than a comparable-performance thermal incinerator, the lower fuel costs of the catalytic incinerator pay this cost differential back very quickly (1/2 to 2 years). Catalytic incineration can not only be used for pollution control, but also for energy recovery from streams containing combustible gases.

This paper provides a context within which the role of human factors engineering (HFE) for Naval ship design may be understood. HFE is defined and its history as part of engineering design teams is traced. The role of HFE in ship systems design is defined, and the HFE Technology for Ships Program, managed by SEA 061R, is described. The rationale for inclusion of HFE in the design process is presented, the methodology whereby it is incorporated into the design process is detailed, methodology to assess the application of HFE is outlined, and the benefits that will accrue as a result of inclusion of HFE considerations in the design process are documented. The counterpoint to inclusion is illustrated through instances of design-induced human errors. A specific application of HFE in the acquisition process is illustrated through use of the Landing Craft, Air Cushion HFE program plan. The difficulties which may be encountered as the size of the target system expands are described. Potential roadblocks to the required incorporation of HFE are examined for their source and possible ameliorative steps.

The structural design of a ship's section is a complicated, repetitive and time consuming task. With the advent of new technology, high speed computers have enabled the ship designer to accomplish in a matter of seconds what would formerly take days to accomplish by hand. The Structural Synthesis Design Program (SSDP) is a N avy developed computer-aided design tool which is used to design (or to analyze) the longitudinal scantlings for a variety of ship cross sections, consisting of any practical combinations of decks, platforms, bulkheads and materials, i.e., various steel and aluminum alloys. The final hull section design will have the lowest practical weight for the chosen geometric configuration, structural arrangements, and imposed loadings. The scantling developed by the program will satisfy all U.S. N avy ship structural design criteria. An explanation of the objective and design elements of N avy ship structures is included. The rationale behind the SSDP design philosophy is developed along with the significant program capabilities. In an attempt to highlight the influence of automated design procedures on the current naval ship design process, the effect of the SSDP on the DDG 51 destroyer structural development is addressed.

Computer control of Rotary Kilns

Computer Control of Rotary Kilns

引用

American control Conference (ACC)

作者： Ray B. Bailey Donald J. Sergi Process Systems Mainager Boeing Engineering and Construction Seattle WA USA

A dynamic lime kiln simulation model has been developed and validated by extensive test data from pulp mill lime kilns. The simulation is used to evaluate control and equipment requirements during transient or upset conditions. control strategies and equipment, or kiln subsystem modifications can be perfected and implemented with a high degree of confidence in rapid installation and startup. This approach has been used to develop a computer-based rotary kiln control system which has been field-proven to meet design goals of: lower energy consumption, improved product quality, reduced equipment wear and tear, and automatic closed-loop control within days of initial installation. The rotary kiln control system is in operation at a Magnesia plant and at two West Coast pulp mills, where the systems have demonstrated an 8% - 10% fuel efficiency improvement in addition to other operational benefits.
