Abstract
A method for the introduction of inorganic solid bodies into hot, liquid melts, whereby inorganic solid bodies are added to a plastic containing hydrocarbon and the mixture obtained is added to the hot, liquid melt.
Claims21
A process for improving the refractory properties of a furnace wall comprising the steps of:
- adding inorganic solid particles to a hydrocarbon-containing plastic that has a surface to form a mixture, wherein the inorganic solid particles adhere to the surface of said hydrocarbon-containing plastic and wherein the inorganic solid particles comprise a titanium-containing substance;
- and
- introducing the mixture into a hot liquid melt in a furnace comprising the furnace wall, wherein 90% of the inorganic solid particles have a particle size in the range of from 0.01 μm to 5 mm, wherein the proportion of inorganic solid particles in the mixture of particles and plastic is 0.5 to 90 wt. %.
A process comprising mixing a solid plastic that has a surface with inorganic solid particles so that the inorganic solid particles adhere to the surface of the solid plastic to form a mixture, and adding the mixture to a liquid melt.
A process comprising:
- mixing particulate synthetic titanium dioxide with inorganic solid particles selected from the group consisting of iron oxide, aluminum oxide, magnesium oxide, calcium oxide, a silicate, and a slag forming additive to form a particulate inorganic mixture comprising inorganic particulates;
- and
- mixing the particulate inorganic mixture with solid plastic granules which have a surface such that the inorganic particulates of the particulate inorganic mixture adhere onto the surface of the solid plastic granules to form a granulate plastic flux mixture, wherein 90% of the inorganic solid particles have a particle size in the range of from 0.01 μm to 5 mm.
