PURATE TECHNOLOGY FOR CYANIDE REMOVAL FROM STEEL EFFLUENTS

Per: rafael oliveira machado queiroz (Ecolab), Fábio Schusterschitz da Silva Araújo (Ecolab)

Area: Energy and Utilities

Theme: Water treatment and reuse

Event: 41st Energy

Type: Oral

Date and time: 09/06/22 | 09h00

Room: 11

Abstract:

The need to optimize the use of water, as well as the methods used for its treatment according to the process requirements, is promoting the need for a holistic review of the best practices in effluent treatments. Therefore, at this moment, new processes, instruments, analyzers, among others, are being created and/or improved, with a focus on the environment, operating costs, quality and safety. The use of Purate technology to replace chlorine as an oxidizer has produced technical, operational and safety gains. This happens because technically, this application does not require high pHs, danger with the formation of CNCl, and requires much less time for oxidation. In terms of safety, Purate is superior since it eliminates the use of chlorine, usually supplied in solution and with large volumes stored, increasing the risk in industrial areas. In addition, the Purate technology allows for greater automation and control in its application, added to the benefits of using chlorine dioxide in the treatment of effluents due to its greater selectivity. Added to this, the reduction of corrosion in the distribution lines, the mitigation of secondary compounds with high toxicity, among other problems, are gains directly linked to the Purate technology

UPGRADE AND OPTIMIZATION OF STRETCH LEVELER / SCALE BREAKER DRIVE SYSTEMS FROM GEARBOX MANUFACTURER PERSPECTIVE

Per: THOMAS AZIG (EISENBEISS GMBH)

Area: Forming

Theme: Equipments and rolls

Event: 57th Rolling

Type: Oral

Date and time: 09/06/22 | 09h00

Room: 12

Abstract:

Enhanced material properties and improved requirements in terms of product/surface quality frequently leads existing stretch leveler/scale breaker (SL/SB) drive systems to or beyond its capabilities. The upgrade of such systems implies a variety of aspects in terms of design and optimization: key topics like power and speed enhancement, increase of control accuracy, consideration of a multitude of different load-cases,… need to be addressed simultaneously while the existing plant layout in most cases has to be kept nearly unchanged. On top a monitoring system is to be integrated many times not only to observe system key components, but also to enable predictive maintenance concepts as well as process & product quality improvements.
This article is addressing several key aspects for the conceptional design of a full mechanically coupled SL/SB drive systems, including analysis and differentiation of various load cases to be considered as well as the planetary gear box layout- and dimensional design in the context of different plant layout scenarios. Moreover, the design and implementation of a drive monitoring system to fulfill requirements with respect monitoring, predictive maintenance & process optimization is presented. The aim of this paper is to illustrate plant operators who decided to upgrade such processing lines both the potentials and main topics during the conceptional design phase.*-

ANALYSIS OF THE INFLUENCE OF PHASE TRANSFORMATION ON COIL SLUMP OF HOT ROLLED COILS'

Per: saulo morais de andrade (usiminas)

Area: Forming

Theme: Conventional hot strip mills

Event: 57th Rolling

Type: Oral

Date and time: 09/06/22 | 09h00

Room: 13

Abstract:

The hot rolling is a thermomechanical process characterized by the austenitization during the reheating of slabs, followed by rolling and cooling steps. An important step of this process is the decomposition, or transformation, of austenite during cooling. It is known that when this transformation is not completed, or at least in its majority, prior the coiling, there is a higher tendency of coil slump. This behavior is explained by the volumetric change inherent of austenite decomposition. Coil slump is a critical defect because depending on its magnitude, the coils cannot be sent to subsequent processes or customer. The paper presents a laboratory characterization of the phase transformation during cooling to better understand the occurrence of coil slump in a medium carbon steel and an evaluation based on industrial data of coil slump in steels with carbon content near to 0.10%, with and without microalloying elements, as a function of coiling temperature. To analyze the industrial data, the Choo equation was used to determine Ar3 temperature to infer the influence of phase transformation. It was confirmed that phase transformation can be associated as a determining factor in the coil slump of hot rolled coils.

A FLOW DISTORTION ANALISYS IN A HOT STRIP MILL’S REHEATING FURNACE CHIMNEY

Per: GABRIEL NAZARETH GUEDES ALCOFORADO (ARCELORMITTAL BRASIL SA)

Area: Forming

Theme: Conventional hot strip mills

Type: Oral

Date and time: 09/06/22 | 09h00

Room: 14

Abstract:

For a hot strip mill’s reheating furnace system to maintain a steady condition during normal operation, can be a real challenge. Any disturbance in the combustion process or in the fuel properties can result in environmental emissions out of the chimney. Isokinetic measurements are widely applied for dust measurement instruments calibration. Its purpose is to collect several samples from predefined points in the measurement surface and compare the results with the dust monitor measurement installed. From this comparison, a correction curve is obtained and loaded in the analyzer instrument. Aiming to achieve the best possible accuracy and representative samples, the isokinetic measurement must follow some requirements concerning the sampling points distribution, process, and flow conditions. To achieve a fully developed flow, some standardized and regulated requirements are defined, but once there is an internal pressure control damper direct installed in the stack structure, it can produce flow disturbances. This paper describes a flow profile distortion analysis after the control damper installed in a hot strip mill’s reheating furnace chimney and its possible impacts on isokinetic measurements.
