The flow field, tracer dispersion and uniformity of strands in two designs four-strand tun-dishes under normal conditions single-strand blockage are studied by numerical simulation. casting speed (flow rate) increasing uniformly or non-uniformly to improve the strand condition. cases evaluated a novel outflow percentage analysis method. results show that field tundish does not change significan...

Modern steel making processes are based on electrical arc furnaces (EAF) or converters, secondary metallurgy and CSC equipment. Steel casting processes are carried on as the continuous ones, which today are the dominating methods in global quantities of steel production. These methods make possible production of the continuous castings of predetermined profiles and dimensions, and therefore to ...

calligraphy in plaster molding has long been a unique platform for professional designers and decorative calligraphers due to the ease of molding the plaster and the longevity of the work. since the origin of the kufi alphabet used in plaster inscriptions is simplekufi, it is generallybelieved that the common letters must be drawn alike. however, as exemplified in the phrase under study, the mo...

This article is focused on the description of the main features of an online system for the real time monitoring and prediction of the liquid steel temperature in the ladle and tundish. Monitoring and prediction are based on a combination of analytical and statistical methods. Thus e.g., the temperature profiles of the walls are calculated using multi-layer implicit difference scheme taking int...

in this paper the traditional covering plaster of masonry buildings is supplied with polypropylene and steel fiber to enhance their seismic behavior. the plaster mix proportion is determined by some initial mortar tests. also, one story, single span masonry building specimen plastered with different mortars is tested on a shaking table 8 times under a seismic input and the performance of the sp...

An inner tube was inflated and then surrounded with plaster wool and plaster-of-Paris bandages. The plaster and the wool were next progressively divided. There was no significant reduction of the pressure inside the tube until both the plaster and the wool had been divided and separated from the inner tube along the entire circumference. These findings demonstrated that wool and plaster applied...

The physical properties of plaster bandages are a very important factor in achieving the basic functions of immobilization (maintaining bone fragments in the best possible position), which directly affects the speed and quality of fracture healing. This paper compares the differences between the physical properties of plaster bandages (mass, specific weight, drying rate, elasticity and strength...

Various materials have been used since ancient times to help immobilise fractures. In this review, we discuss the history and developments of these materials as well as plaster of Paris. There has been a recent trend away from non-operative management of fractures, and skills in the use of plaster of Paris are declining. For the successful treatment of patients, it is important to appreciate ho...

In the continuous casting process, fluid flow of molten steel in tundish is a non-isothermal state. Because geometric shape and process parameters multi-strand tundish, behavior each strand quite inhomogeneous, difference temperature, composition inclusion content between great, which directly affects quality products. this paper, flow, heat transfer phenomena trajectories four-strand with with...
