摘要： PURPOSE:To form a uniform inorganic substance film on a high-temperature object by beforehand adding a substance meltable upon coating to an aqueous solution of a high-melting inorganic substance to be coated on the high-temprature object. CONSTITUTION:In the formation of an inorganic film on the surface of an object, steel material, filtering material, etc., for protecting it from rusting, etc., 0.1-40% an alkali metal salt or alkaline earth metal salt of boric acid, phosphoric acid, etc., as an additive, is beforehand added to an aqueous slurry or solution of an inorganic substance, e.g., a metal, clay, etc., which is to be coated on an object at 300- 1,400 deg.C. Thus, the adhesiveness of the inorganic substance to the object is increased with the aid of the additive which is easily melted and bonded to the object as soon as it comes into contact with the high-temperature object, thus permitting uniform inorgnic film to be formed.

摘要： PURPOSE:To insulate the heat of steel materials efficiently by coating a heat insulating material prepd. by adding a binder to refractory inorg. fibers and inorg. particles and mixing these to the slurry form by water on the surfaces of high temp. steel materials. CONSTITUTION:At the time of subjecting high temp. steel ingots of 300-1,400 deg.C such as continuously cast steel ingots, blooms after blooming and the like further to secondary working such as hot rolling in the next process, it is necessary to raise the temp. of the ingots up to their hot working temp., and therefore the heat insulating material of the following composition is coated on the above-mentioned high temp. ingots, thereby suppressing their cooling and reducing the burden of heating furnaces. As the heat insulating material, 100 parts inorg. fibers such as asbestos, rock wool, glass fibers or slag wool and further 0.1-100 parts inorg. particles of

摘要： PURPOSE:To provide a covering agent of superior heat insulation characteristics for heat insulation of steel materials by adding a binder to a heat generating agent consisting of Al powder and an oxidizing agent and a low temp. igniting material, and mixing these to the slurry form by water. CONSTITUTION:One or >=2 kinds of phosphoric acids, boric acids, silicic acids and their alkali metal salts are added as a binder at 1-100 parts to 100 parts a heat generating agent consisting of 10-50% powder Al, 2-40% one or >=2 kinds of powders of iron oxide, manganese dioxide, nitrate, etc. as an oxygen supplying source for combustion of the same, 20-60% Al2O3 powder as a heat insulating agent, and 0.5-20% one or >=2 kinds of org. materials or carbonaceous materials such as wood meal, pulp powder, charcoal powder and the like which ignite and burn at low temps., and these are mixed. Water is added to this and the mixture is prepared into the slurry form, thence this is coated on the surfaces of high temp. steel materials such as continuously cast steel ingots, blooms after blooming and the like, so that the surface temps. of the steel materials are raised up to near their inside temps. by the combustion of Al and the combustion and heat generation of the low temp. igniting materials.
