Effect of mould expansion on pattern allowances in sand casting of steel
For steel castings produced in sand moulds, the expansion of the sand and have a significant impact on the final size and shape of the casting. Experiments are conducted using a cylindrical casting to study this effect for different sands (silica and zircon) and different sand binder systems (phenolic urethane and sodium silicate). The type of sand has a significant effect on the final casting ...
متن کاملLooking into continuous casting mould
When you look into the continuous casting mould you can see very little. Consequently, steelmakers have had to rely on plant trials, simulation experiments and physical property measurements on fluxes and steels to gain an understanding of the mechanisms responsible for process problems and product defects. However, in recent years, mathematical modelling has advanced to the stage where they ca...
متن کاملApplication of TRIZ Theory in Patternless Casting Manufacturing Technique
The ultimate goal of Patternless Casting Manufacturing (referred to as PCM) is how to obtain the casts by casting the sand mold directly. In the previous PCM, the resin content of sand mold is much higher than that required by traditional resin sand, so the casts obtained are difficult to be sound and qualified products, which limits the application of this technique greatly. In this paper, the...
متن کاملBiomaterials by freeze casting.
The functional requirements for synthetic tissue substitutes appear deceptively simple: they should provide a porous matrix with interconnecting porosity and surface properties that promote rapid tissue ingrowth; at the same time, they should possess sufficient stiffness, strength and toughness to prevent crushing under physiological loads until full integration and healing are reached. Despite...
متن کاملAnalyzing the Failure of Master Mould in Casting of Copper Anode Moulds and Suggesting a more Suitable Metal Mould
Master moulds are used to cast copper anode moulds. These iron moulds are made of grey or nodular cast irons. According to desirable properties of ductile irons, it was expected that ductile cast iron ...
