| 141 | Binding agents containing titanic acid esters for the preparation of coating compositions and refractory bodies, and a method for the preparation of these binding agents | US461072 | 1983-01-26 | US4578487A | 1986-03-25 | Dieter Barfurth; Heinz Nestler |
| The present invention relates to binding agents for coating compositions which can be used for making foundry molds. The new compositions contain known polymeric titanic acid esters which are treated with chelating agents. The preferred chelating agents are beta-dioxo compounds. The chelating agents are contained in the binding agent in amounts between 0.2 and 1 gram molecule per gram atom of titanium. The new binding agents can be prepared in a simple manner from titanic acid esters, water and the chelating agent, the amount of water being selected in accordance with the degree of condensation desired in the polymeric titanic acid ester. | ||||||
| 142 | Erosion-resistant refractory | US461175 | 1983-01-26 | US4407972A | 1983-10-04 | Bohus Brezny |
| A refractory shape having improved resistance to erosion in metal melting vessels and high modulus of rupture, comprising an anhydrous refractory material, an anhydrous organic binder, from 0.3% to about 30% finely divided elemental carbon having a particle size ranging from 0.01 to about 1 mm, and from 0.3% to about 10% particulate elemental magnesium, based on the weight of the refractory shape. Addition of both elemental carbon and elemental magnesium results in a synergistic improvement in slag erosion resistance. | ||||||
| 143 | Basic refractory cementitious material and components thereof | US371864 | 1982-04-26 | US4400474A | 1983-08-23 | Martin Copperthwaite; Michael A. Roberts |
| A cementitious formulation which is self-setting when mixed with water, and which can be cast into monolithic refractory components capable of resisting molten metal and repeated thermal shocks, has three main components: high purity magnesia (at least 94% by weight being MgO); high purity alumina (at least 98% by weight Al.sub.2 O.sub.3) and high alumina cement (preferably 75% Al.sub.2 O.sub.3) by weight, or greater). The magnesia may be 60 to 95% by weight of the three components and the alumina amounts to at least 1% by weight of the three components. Castings produced from the formulation can survive repeated flame testing even after exposure to firing at elevated temperature: known, conventionally pressed and similarly fired magnesia refractories may not survive a single flame test. | ||||||
| 144 | Amorphous refractory settable at low temperatures | US266299 | 1981-05-22 | US4393143A | 1983-07-12 | Satoru Yoshinaka; Masao Fushida; Tatsuzi Kimoto |
| An amorphous refractory settable at low temperatures comprises a usual refractory material, a metal powder in an amount of 0.5 to 5% by weight based on the whole amount of the refractory and serving as a sintering agent and a phosphate glass powder in an amount of 0.5 to 3% by weight based on the whole amount and serving as a sintering and setting agent. A pitch powder can be further incorporated in the refractory in an amount of 0.1 to 6% by weight based on the whole amount to render the refractory settable more effectively at low temperatures. The refractory is usable in the form of a dry powder without using any water or other liquid for lining troughs and containers for molten metals. | ||||||
| 145 | Coating compositions for liners of molten metal troughs and ladles | US241060 | 1981-03-06 | US4342597A | 1982-08-03 | William F. Brown |
| A composition for coating the refractory liners of ladles and troughs for pouring and/or conveying molten metals comprising an aqueous dispersion containing finely divided zirconia, a colloidal silica, finely divided mica, finely divided zircon, finely divided bentonite and, optionally, an inert coloring agent.

| 146 | Repairing mortars for silicon carbide bricks | US061551 | 1979-07-27 | US4249947A | 1981-02-10 | Haruyoshi Koga |
| In structures of silicon carbide brick the leakage of molten metal or vaporous metal through breaks in joints or a crack is prevented by hot applying mortar comprising a major component of zircon and a minor component of borates or boric acid, phosphoric acid and colloidal silica to the breakages. Adhesiveness of mortar to the breakages is improved by incorporating further agalmatolite or kaolin into the mortar. | ||||||
| 147 | High alumina-chromia plastic refractory mix | US862873 | 1977-12-21 | US4125409A | 1978-11-14 | James R. Friedrichs; Edward A. Snajdr; Bela Klaudinyi |
