摘要： A new and improved carbon sand and a method of treating a petroleum fluid coke, having a spherical or ovoid particle shape and a size suitable for a core or mold surface in the foundry industry, by heating or roasting the carbon particles at a temperature in the range of about 1000.degree. F. to about 1500.degree. F., particularly about 1200.degree. F. to about 1400.degree. F., for a time sufficient to volatilize from the carbon particles substantially all of the organic contaminants volatilizable at the roasting temperature, and a method of casting molten metal against the heat treated carbon particles, combined with a suitable binder, to form cast metal parts. The carbon sand also is useful in forming shell molds and shell cores and otherwise using the carbon sand to replace other molding and coremaking sands used in any of the various molding and coremaking processes with any of the various binder systems practiced by the foundry industry.

摘要： A plow for use in a sand mulling machine having a vertically axised bowl formed with a bottom wall and a cylindrical peripheral wall, and a rotatable hub upon which the vertically axised mulling rollers are mounted for mulling material against the peripheral wall. The plow comprises an elongated generally flat plate secured to the hub for rotation therewith, and located adjacent the bowl peripheral wall at a sloped angle relative to the bowl bottom wall. One narrow end of the plow forms a leading edge arranged closely adjacent to the bowl bottom wall and the opposite end of the plow forms a rear or trailing edge which is spaced from the bottom wall. The rear or trailing portion of the plow is formed with a number of elongated, spaced apart, narrow, fingers providing a comb-like structure wherein material to be mulled is picked up along the plow leading edge and moves upwardly along the plow body and upon and through the comb-like structure formed on the trailing edge portion of the plow.

摘要： A new and improved, non-porous carbon foundry sand and a method of treating a fluid coke, having a spherical or ovoid particle shape and a size suitable for a coating surface, or a core or mold surface in the foundry industry, wherein the carbon sand is processed by heating the carbon particles at a controlled rate to a temperature in the range of about 1900.degree. F. to about 2300.degree. F. during a period of time preferably of more than about 30 minutes, and preferably for a period of about 1 to 2 hours, particularly to about 2000.degree. F. to about 2200.degree. F., and a method of casting molten metal against the heat treated carbon particles wherein the non-porous carbon foundry sand is combined with a suitable binder with which mixture a mold is formed to cast metal parts. The non-porous carbon sand also is useful in forming molds, cores, shell molds and shell cores and otherwise in using the carbon sand to replace other molding an core-making sands used in the foundry industry.
摘要翻译：一种新的改进的无孔碳铸造砂和处理具有球形或卵形颗粒形状和适于涂层表面的尺寸或铸造工业中的芯或模具表面的流体焦炭的方法，其中碳通过在约1900°F至约2300°F的温度范围内以受控的速率加热碳颗粒来处理砂，优选在大于约30分钟的时间内，优选约为约30分钟 1至2小时，特别是约2000°F至约2200°F，以及将热熔处理的碳颗粒浇注熔融金属的方法，其中将无孔碳砂铸造砂与合适的粘合剂组合，模具形成铸造金属部件。无孔碳砂也可用于成型模具，芯，壳模和壳芯，否则可用于使用碳砂替代铸造业中使用的制砂砂的其他成型。
