Abstract

271,847. United States Metals Refining Co., (Assignees of Marks. A.). May 6, 1926, [Convention date]. Addition to 244,391, Refractory substances containing magnesite.- In the manufacture of magnesite refractories wherein the ground material is mixed with linseed or other organic siccative oil to render it plastic, as described in the parent Specification, one or both of the followng modifications are introduced, viz. :-(1) the magnesite consists of a mixture of particles of different degrees of fineness, (2) the moulded articles are dried firstly in a humid atmosphere at low temperature and the humidity is gradually diminished while the temperature is raised. The magnesia is preferably of a dead.burnt mixture of Austrian and American magnesite; about half of it should pass a screen of 100 meshes per inch while all passes a screen of 30 meshes per inch. The oil, preferably linseed, is used in the proportion of 5-7 per cent by weight of the refractory material. The dried bricks &c. may be used in an unburnt condition. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following features; (1) the oil may be heated to increase its viscosity before or aiter mixing with the body material (2) thinners and driers may be added to the oil if required, (3) the bricks may be burnt at 1400-1500‹ C. This subject-matter does not appear in the Specification as accepted.
