摘要:

ABSTRACTThe mean specific heat of pure aluminum and magnesium oxides has been determined from room temperature up to 1700°C and 1800°C, respectively. The specimens were heated in a vertical carbon tube furnace with a magnesite tube liner for oxidizing conditions. A special calorimeter was designed and used to prevent the loss of heat by vaporization of the water when the white hot specimens were immerse

摘要:

ABSTRACTThe modern railroad‐car tunnel kiln can fire structural tile economically in sufficient quantities for commercial operation. The setting arrangement is important both as to arrangement of flues and also as to the stability of the structure. Various sizes of tile can also be placed on the same car. There are approximately three tons of tile on each car. The kiln used is a Harrop car tunnel kiln, 350 feet long with a cross‐section of 5 feet 8 inches by 5 feet 5 inches. Either oil or powdered coal is used as fuel. The tile are in the kiln a total of 29 hours, giving a total production of 130 tons per twenty‐four

摘要:

ABSTRACTThe method used to secure a salt glaze on a red‐firing clay which vitrifies at a temperature too low to salt glaze normally consists essentially of raising the temperature quickly for short intervals by rapid combustion of thin soft‐wood edgings and applying the salt at maximum temperature during several successive interv

摘要:

ABSTRACTAn apparatus is described which automatically plots a curve and coordinates the shrinkage associated with the drying loss at any point on the curve. From such curves correct dryir.g schedules may be developed. The apparatus may be used in a drier to indicate correct drying performance and the curves furnish valuable information as to the drying peculiarities of bodies not usually available.
