摘要： An improved filter assembly for molten metal is described. The assembly has a canister with at least one port wherein the port allows filtered molten metal to flow from the canister. A plurality of filter elements is in the canister wherein the filter elements separate a volume of the canister into a primary chamber and a secondary chamber wherein the secondary chamber is in direct flow communication with the port. A ported cover is over the canister wherein the ported cover prohibits unfiltered molten metal from flowing directly into the secondary chamber. The molten metal flows from the primary chamber to the secondary chamber through a filter element.

摘要： The use of wollastonite fibers having relatively long average fiber lengths as reinforcement agents for unfired sanitaryware bodies. The addition of refined wollastonite to sanitaryware bodies exhibited improved resistance to propagation of cracks, reduced drying and firing shrinkage, fluxing activity, an HF release inhibition upon firing. Reduced shrinkage and increased permeability improves the resistance to cracking during rapid drying and allows faster time schedules to be employed.
摘要翻译：使用具有较长平均纤维长度的硅灰石纤维作为未烧发的卫生洁具体的增强剂。将精制硅灰石添加到卫生洁具体中表现出改善的耐裂纹扩展性，降低的干燥和焙烧收缩率，助熔活性，焙烧时的HF释放抑制。减少收缩率和增加的渗透性可以提高快速干燥时的抗裂性，并允许采用更快的时间表。

摘要： A method for inoculating molten iron. The method comprises passing the molten iron through a filter assembly at an approach velocity of about 1 to about 60 cm/sec. The filter assembly comprises a filter element and an inoculation pellet in contact with the filter element. The pellet has an inoculant dissolution rate of at least 1 mg/sec. to no more than 320 mg/sec. and comprises about 40-99.9%, by weight, carrier comprising ferrosilicon. The pellet further comprises about 0.1-60%, by weight, at least one inoculating agent selected from a group consisting of cerium, strontium, zirconium, calcium, manganese, barium, bismuth, magnesium, titanium and aluminum or from rare earths.

摘要： The desulfurization agent for molten iron is made up of 70 to 95% commercial calcium carbide, 5 to 25% silicon dioxide, 0 to 10% of a metal oxide, and 0 to 5% calcium fluoride. The metal oxides are iron oxides and manganese oxides. The desulfurizing agent has been found to reduce the amount of calcium carbide in the resulting slag.
