This paper evaluates the treatment of textile dyeing wastewater by using steel scrap as adsorbents and heterogeneous catalysts for Modified Fenton oxidation. The efficiency of the process was explored as a function of the experimental parameters: pH, hydrogen peroxide concentration and Steel scrap content. The composites with high steel scrap content were effective to adsorb colour and COD in t...

M. Suliga, R. Kruzel, Czestochowa University of Technology, Czestochowa, Poland In the paper the influence of bidirectional bending on breaking force of steel cord has been assessed. Tests were carried out under laboratory conditions on three types of cord. It was found that bidirectional bending of steel cord cause the deterioration of strength properties and weakening of steel cord as a resul...

AE monitoring from various types of stress corrosion cracking (SCC) has been conducted for the past 15 years in our laboratory. This paper discusses AE results of active-path dissolution-type SCC of austenitic stainless steel in chloride solution and fused salt, fluoride and polythionic acid solutions, brass in ammonia (Mattosson's solution), and carbon steels in nitrite solution. Transgranular...

According to the characteristics of low-carbon steel pitting acoustic emission signal, one new characteristic analysis-WICA is proposed. The main idea of WICA is that based on the independent component analysis blind source separation technology as well as the wavelet transformation decomposition technology, proposed determines the low-carbon steel pitting source number according to the energy ...

The purpose of the tests was to determine whether and how sterilisation process of samples made of AISI 316L stainless steel with diff erent strain impacts their corrosion resistance. Tests were made on steel samples that had been electrochemically polished in order to assure proper surface roughness. In order to evaluate the infl uence of sterilisation on physical and chemical properties of st...

Investigations on flexural and tensile properties of GFRP laminates influenced by stainless steel wire reinforcement were carried out as a novel approach. Plain GFRP laminates and GFRP laminates reinforced with stainless steel wires at different depth with various pitch distances were fabricated by hand layup method. The composite specimens reinforced with steel wires were exposed to low freque...

Although the Steel Mill Slab problem (prob 38 of CSPLib) has already been studied by the CP community, this approach is unfortunately not used anymore by steel producers since last century. Continuous casting is preferred instead, allowing higher throughput and better steel quality. This paper presents a CP model related to scheduling of operations for steel making with continuous casting. Acti...

There are over six hundred thousand bridges in the U.S. which require great amount of human effort along with expensive and specialized equipment for maintenance. Current bridge inspections are manually performed by inspectors which are inefficient and unsafe. This paper presents visual and three dimensional (3D) structure inspection for steel bridges and steel structures using the developed cl...
