Various methods have been used to enhance the properties of steel during solidification. The continuous casting mold and submerged entry nozzles play an important part to produce the clean and defect free solidified slabs [7]. The melt flow ...

Evidence that indoor dampness and mold growth are associated with respiratory health has been accumulating, but few studies have been able to examine health risks in relation to measured levels of indoor mold exposure. In particular, little is known about the contribution of indoor molds to the development of allergic sensitization. As a part of an ongoing study examining the effects of ambient...

Abstract: A direct-chill (DC) cast process of an aluminum ingot of size 3200×1292×320 mm is analyzed numerically by the analysis of a fixed controlled system. The study investigates the DC processes in which liquid aluminum is cooling continuously in mold and then with water spray at the exit of mold. An inverse method is applied to measure heat transfer coefficient on water cooling surface exp...

Soft tissue prostheses such as artificial ear, eye and nose are widely used in the maxillofacial rehabilitation. In this report we demonstrate how to fabricate soft prostheses mold with a low cost desktop 3D printer. The fabrication method used is referred to as Scanning Printing Polishing Casting (SPPC). Firstly the anatomy is scanned with a 3D scanner, then a tissue casting mold is designed o...

Previous studies of allergic rhinitis in children have not documented the environmental risk factors for infants at age one. We examined the relationship of environmental tobacco smoke (ETS) and visible mold exposures on the development of allergic rhinitis, rhinitis and upper respiratory infection (URI) in a birth cohort where at least one parent was skin prick test (SPT) positive. ETS exposur...

Mold powders are fluxing agents used as raw materials in the steel industry, which play very important role in processing stability and final surface quality of a product. Surface quality depends particularly on the viscosity and the heat transfer of infiltrated mold flux between the mold wall and the solidified steel shell. Heat flux across the interfacial gap depends on thermal properties of ...

Fluid flow in the mold region of the continuous slab caster at Panzhihua Steel is investigated with 0.6-scale water model experiments, industrial measurements, and numerical simulations. In the water model, multiphase fluid flow in the submerged entry nozzle (SEN) and the mold with gas injection is investigated. Top surface level fluctuations, pressure at the jet impingement point, and the flow...

relative resistance of 43 iranian as well as introduced apple cultivars to blue mold (penicillium expansum) was studied within years 2010-2011. the fruit physicochemical traits were also evaluated as measures of potential resistance to decay. local p. expansum strains were isolated from decayed apple fruits and the most aggressive isolate (5,000 spores ml-1) used as inoculum. fruits were wound-...

Fluid flow in the mold region of the continuous casting process is responsible for surface defects, slag entrainment, and other steel quality problems. Thus, it is very important to choose nozzle geometries and operating conditions that produce flow patterns within an operating window that avoids these problems. Operating conditions which control mold flow problems include the mold cross sectio...
