A casting defect is an undesired irregularity in a metal casting process. Some defects can be tolerated while others can be repaired, otherwise they must be eliminated. They are broken down into five main categories: gas porosity, shrinkage defects, mould material defects, pouring metal defects, and metallurgical defects.
James Beaumont Neilson, previously foreman at Glasgow gas works, invented the system of preheating the blast for a furnace.He found that by increasing the temperature of the incoming air to 149 °C (300 °F), he could reduce the fuel consumption from 8.06 tons of coal to 5.16 tons of coal per ton of produced iron with further reductions at even higher temperatures.

The advantage of the induction furnace is a clean, energy-efficient and well-controlled melting process, compared to most other means of metal melting. Most modern foundries use this type of furnace, and many iron foundries are replacing cupola furnaces with induction furnaces to melt cast iron, as the former emit much dust and other pollutants ...
Silicon nitride has been recently used as a surface igniter for gas furnace and diesel engine glow plugs. Such heating elements or glow plugs reach a maximum temperature of 1400 °C and quickly ignite gasoline or kerosene. The material is also used in diesel and spark ignited engines for other combustion components and wear parts. [19]
For example, a low-temperature vacuum oven can be used for drying biomass much more efficiently than drying alone. [3] Similarly, microwave-vacuum drying has shown potential for drying foods like cranberries. [4] [5] At temperatures below 1200 °C, a vacuum furnace is commonly used for the heat treatment of steel alloys. Many general heat ...
As the carbon burns off, the melting temperature of the mixture rises from 1,150 to 1,540 °C (2,100 to 2,800 °F), [14] [15] so the furnace has to be continually fed during this process. The melting point increases since the carbon atoms within the mixture act as a solute in solution which lowers the melting point of the iron mixture (like ...

Directional solidification is the preferred technique for casting high temperature nickel-based superalloys that are used in turbine engines of aircraft. Some microstructural problems such as coarse dendritic structure, long dendrite side branches, and porosity hinder the full potential of single crystal ni-based alloys. [ 6 ]
