Inclusion evolution during refining and continuous casting. 2014 Investigation of Hot Ductility Gradients in Duplex Stainless Steel in the Beginning of the Continuous Casting Process Key words: Continuous casting, start-cast, hot, Stainless steel can corrode in service if there is contamination of the surface. Both pickling and passivation are chemical treatments applied to the surface of stainless steel to remove contaminants and assist the formation of a continuous chromium-oxide, passive film. Pickling and passivation are both acid treatments and neither will remove grease or oil. If the fabrication is dirty, it may.

stainless steel. 1 Analysis of burn-on defect Up to now, only a few literatures reported burn-on defects on the surface of hydroturbine blade castings. As early as 1976, И.Н.Примака described a similar casting defect [3]. It was stated that this defect is caused by decomposition of calcium carbonate and magnesium carbonate in chromium sand mould at high temperature. In 2005, Huang Jin In order to meet the increased demand for stainless steel on the domestic market, POSCO produces 380 kt of stainless steel annually by the EAF-AOD---continuous casting process.

The high melting point of steel, and the lack of technology available to melt, process, and control metals at such high temperatures, delayed the development of a steel casting industry. These challenges were overcome by advances in furnace technology. The development of continuous casting to produce semi-finished products is now so far advanced that almost any grade of steel can be continuously cast, and in …

In order to meet the increased demand for stainless steel on the domestic market, POSCO produces 380 kt of stainless steel annually by the EAF-AOD---continuous casting process. The most commonly used metals are austenitic and martensitic stainless steel, Hastalloy and other nickel-based steels, tool steel, cobalt-based alloys, brass, bronze, and copper. Not all metals

continuous casting of steel. It then reviews some of the advanced mechanistic models of these phenomena and provides a few examples of the information and insights gained from them. These model applications focus on the mold region, where many continuous casting defects are generated. 2 II. Process Description In the continuous casting process, pictured in Figure 1, molten steel flows … Selected grades of duplex stainless steel castings and their welds, in comparison with their wrought counterparts, were evaluated, regarding corrosion performance and mechanical properties and weldability. Multiple heats of cast duplex stainless steel were evaluated in the as-cast, solution annealed (SA) static cast and SA centrifugal cast conditions, while their wrought counterparts were

These model applications focus on the mold region, where many continuous casting defects are generated. 2 II. Process Description In the continuous casting process, pictured in Figure 1, molten steel flows … stainless steel are evaluated against the criteria for classification, as contained in Annex VI of European Council Directive 92/32/EEC, amending Directive 67/548/EEC.

Stainless Steel Casting. Steel castings are, in general, of higher strength and ductility than cast iron. Castings of alloy steel have high strength, and those of stainless steel are highly resistant to corrosion., Stainless Steel Castings. Stainless Alloy castings can be used in a variety of applications where corrosion resistance is required at normal and elevated temperatures, along with reasonable strength, they offer good wear resistance and typical uses range from Flame proof and Explosion proof Enclosures to Valve Control equipment..

INCLUSIONS IN CONTINUOUS CASTING OF STEEL. Quality Prediction in Continuous Casting of Stainless Steel Slabs F Surface defects in the continuous casting process require treatment by grinding. This extra phase in the process causes lower throughput of final product and extra energy costs. The elimination of slab treatment after casting implies that slabs can be direct rolled or hot charged, resulting in higher throughput and lower The continuous casting of stainless steels is now an established technology, although newer processes like thin-stripcasting and horizontal casting are the harbingers ofan emerging era. This review examines the various aspects of the continuous casting of stainless steels. The different processes employed to manufacture stainless-steelbillets, blooms, slabs, and strip are described.

Alloy Shrinkage Factors for the Investment Casting Process ADRIAN S. SABAU This study deals with the experimental measurements and numerical predictions of alloy shrinkage factors (SFs) related to the investment casting process. The dimensions of the A356 aluminum alloy casting were determined from the numerical simulation results of solidification, heat transfer, fluid dynamics, and The high melting point of steel, and the lack of technology available to melt, process, and control metals at such high temperatures, delayed the development of a steel casting industry. These challenges were overcome by advances in furnace technology.
