    摘要: The invention provides a colloidal refractory system for an electric arc furnace or another pyrometallurgical converter having a hearth, a shell, and a roof. The colloidal silica refractory includes alumina having a range of about 55 percent through about 90 percent by weight, silicon carbide having a range of about 2.5 percent through about 30 percent by weight, silica having a range of about 2 percent through about 20 percent by weight, and carbon having a range of about 0.1 percent through about 4 percent by weight. An aqueous colloidal silica binder provides the silica. The colloidal refractory system has high-temperature strength and resists the attack from slag and off-gases.

    摘要: An improved castable refractory composition having excellent resistance to attack from slag can be efficiently transported to a destination, such as a mold, using a pump. The castable refractory composition includes about 36-92% by weight silicon carbide, about 8-20% by weight of a colloidal silica binder, and a balance substantially of other refractory materials which can include alumina, microsilica, graphite, and a setting agent. The composition of the invention can be used alone or in addition to a conventional refractory casting material to form a refractory lining. When used together, the conventional refractory composition is used to construct a lower layer in the refractory lining, and the composition of the invention is used to construct an upper refractory layer above the lower layer.

    摘要: Disclosed is a multi-part form comprising a form set with a first form part having prerecorded information thereon and overlying a second form part. Variable information recorded on the first form part is transferred to the second form part, preferably by carbonless transfer using infrared adsorptive dyes, such that the variable information appearing on the second form part is readable by current standard facsimile machines. The second form part is preferably blank, although a minimal quantity of prerecorded information may be provided on the second form part. The second form part is then used as the transmission copy for a facsimile machine whereby reduced time and costs of transmission is effected. The received copy of the facsimile transmission may be provided with an overlay whereby a reproduction of the first form part, including both variable and prerecorded information, may be provided.
