Abstract
Addition agents are blended with a modified tall oil pitch binder and briquetted, extruded, molded, pelletized, or tabletized into a unitary composition. This compacted composition is then fed into a metallurgical operation, such as steel-making, at an appropriate stage in the operation to effect a desirable composition or property. The tall oil pitch binder being modified chemically with either a polycarboxylic acid, a polyamine, a polyisocyanate, an epoxy resin or a polyol.
Claims11
A method of introducing addition agents into a metallurgical operation which comprises:
- (a) blending the addition agents under hot melt conditions with a modified tall oil pitch binder having a tensile strength greater than 25 psi and a deflection index greater than 1;
- (b) compacting the blend into a unitary structure;
- and
- (c) feeding the compacted structure into an appropriate stage in the metallurgical operation to effect the desired composition or property.
A method of introducing addition agents into a metallurgical operation which comprises:
- (a) blending from about 50 to 99 weight percent of the addition agents under hot melt conditions with from about 1 to 50 weight percent of a modified tall oil pitch binder wherein the binder comprises from about 1 to 50 weight percent of an organic or inorganic filler and from about 99 to 50 weight percent of a tall oil pitch chemically modified with either a polycarboxylic acid, a polyamine, a polyisocyanate, a polyol, an epoxy resin, an alkylated amino resin or a combination thereof to provide a tall oil pitch containing polyamide, polyester, polyether, or polyurethane structural moieties, or combinations thereof;
- (b) compacting the blend into a unitary structure wherein the manner of compacting is selected from the group consisting of briquetting, extruding, molding, pelletizing, and tabletizing;
- and
- (c) feeding the compacted structure into an appropriate stage in the metallurgical operation to effect the desired composition or property.
