Thermal Dilatation

Abstract The main bulk density representation in the molding material is opening material, refractory granular material with a particle size of 0.02 mm. It forms a shell molds and cores, and therefore in addition to activating the surface of the grain is one of the most important features angularity and particle size of grains. These last two features specify the porosity and therefore the permeability of the mixture, and thermal dilatation of tension from braking dilation, the thermal conductivity of the mixture and even largely affect the strength of molds and cores, and thus the surface quality of castings. [1] Today foundries, which use the cast iron for produce of casts, are struggling with surface defects on the casts. One of these defects are veining. They can be eliminated in several ways. Veining are foundry defects, which arise as a result of tensions generated at the interface of the mold and metal. This tension also arises due to abrupt thermal expansion of silica sand and is therefore in the development of veining on the surface of casts deal primarily influences and characteristics of the filler material – opening material in the production of iron castings.

Insight Into

The paper aims to provide an insight into the thermo-physical changes of in-situ tailored hybrid polymer based composite materials based on two different synthetic reinforcements with the aim of sizing both architecture stacking sequences and reinforcement type’s influence on their effective linear coefficient of thermal dilatation (CTE). The samples were subjected to a step ramp temperature increase up to 250 °C, followed by their CTE variation monitoring and assessment. Data processing and comparison further contribute to expand knowledge and appropriate personal database aiming material design, manufacturing error minimization and cost reduction.

Leakage Assessment

Bolted flanged joint assemblies may begin to leak some time following a successful hydrostatic test. One of the reasons is that the gasket experiences a drop in its initial compressive stress due to creep, thermal dilatation, and thermal degradation. The need to pay attention to the relaxation behavior of bolted joints for high-temperature applications is recognized by the ASME Code, but no specific guidelines are given to help engineers, neither at the design nor maintenance levels. This paper deals with the basic analytical tools that have been used to develop a computer program “SuperFlange” that can be used to make accurate predictions of the relaxation of bolted flanged joints, and hence be able to provide a reasonable leakage assessment over time. A simplified analytical method of relaxation analysis will also be presented. These proposed methods are supported by test results obtained on a real bolted joint fixture and by FE modeling. A strong emphasis will be put on flanged joint rigidity, which is one of the major controlling parameters of relaxation besides the material properties involved.

This paper presents a new visualization method of complex sound sources in combined fridge freezers. Measurement method with sixty array microphones in free sound field conditions is used. Laboratory acoustic measurements using an algorithm of the complex sound sources visualization are performed. With this method, sound effects are successfully identified, localized and calculated. The individual crack noises emitted as a result of thermal dilatation of different types of material in the transitional cooling modes of the household refrigerator.
