The Challenge: Improving the Efficiency of a Tube Drawing Bench
ثبت نشده
چکیده
Greenville Tube Company (GT), a manufacturer of high-precision, small-diameter stainless steel tubing, conducted an in-house system performance optimization project to improve the efficiency of its No. 6 tube drawing bench. This tube drawing bench plays an integral role in the production process, but severely hindered the productivity and energy efficiency of the facility. GT’s plant engineer, with the technical assistance of Evans Electric Motors, Inc. and Baldor Electric Company, evaluated the systemic problems in GT’s production facility and replaced the original motor and inefficient eddy current clutch drive with an energyefficient motor with vector control. As a result of the changes implemented, GT, a subsidiary of the Delaware-based Chart Industries, discovered that energy efficiency and improved productivity often go hand-in-hand. This Showcase Demonstration Project reduced total annual energy consumption by 148,847 kWh, or 34 percent and resulted in electrical, labor, and material savings of $77,266. The simple payback was just over 5 months.

A hybrid approach based on numerical, statistical and intelligent techniques for optimization of tube drawing process to produced squared section from round tube
In the tube drawing process, there are a bunch of parameters which play key role in process performance. Thus, finding the optimized parameters is a controversial issue. Current study aimed to produce a squared section of round tube by tube sinking process. To simulate the process finite element method (FEM) was used. Then, to find a meaningful kinship between process input and output parameter...
متن کاملImproving Cyclone Efficiency by Recycle and Jet Impingement Streams
In this paper a new process is presented for improving efficiency of cyclone de-dusting systems. The cyclone is coupled with a specially designed cylindrical chamber which includes a rotating tube inside it with air impinging nuzzles, drilled on the peripheral surface of the tube. The nuzzles help in pushing and throwing the particles to the outer radius distances during downward flow of du...
متن کاملExperimental Study of Chemical Absorption of CO2 in a Bench-Scale Spray Dryer Absorber
The removal of CO2 through chemical absorption in a bench-scale spray dryer absorber was investigated experimentally using the lime slurry as absorbent. The effect of important operating parameters on CO2 removal efficiency has been investigated; in selected ranges of operating parameters, increasing gas inlet temperature and absorbent concentration lead to permanent efficiency decline, increas...

Deep drawing of two-layer sheet is a suitable way to achieve product with a desired shape and desired properties in sheet metal forming technology. Control of deep drawing parameter such as thinning is the most important challenge in this process. The most difficult part of this challenge is differences in material properties and geometry of each layer. In this paper, numerical approach has bee...
متن کاملStiffness-based Approach for Preliminary Design of Framed Tube Structures
A parametric formulation for preliminary design of tubed-system tall buildings is presented in which some optimality criteria and practical constraints are considered. Here, a minimum compliance optimization formulation, developed by other researchers, is applied to a framed-tube structure. The tube behavior is modeled as a cantilevered box beam. Independent variable in this problem is thicknes...
