Abstract
A briquette and binder for use in making the same are disclosed. The briquette including: a ferrous or ferro-alloy steel by-product; a binder mixture making up about 0.025% to about 10% of a batch weight, the binder mixture including: a polyvinyl alcohol resin comprising about 0.025% to about 30% of the binder mixture; a sodium hydroxide and diethanolamine phenolic resin comprising about 1% to about 20% of the binder mixture; and water making up the remainder of the binder mixture; a resin powder comprising about 0.01% to about 10% of the batch weight; and where the briquette, when cured, includes about 0.05% to about 10% of the binder mixture.
Claims13
A briquette, the briquette comprising:
- a ferrous or ferro-alloy steel by-product;
- a binder mixture, wherein the briquette is formed from an uncured batch material comprising about 0.025% to about 10% by weight of the binder mixture, wherein the binder mixture comprises—
- about 0.025% to about 30% of a polyvinyl alcohol resin,
- about 1% to about 20% of a phenolic resin,
- about 0.05% to about 5.0% of an ester-based hardener, and
- water forming a remainder of the binder mixture;
- a resin powder, wherein the uncured batch material comprises about 0.01% to about 10% by weight of the resin powder;
- and
- wherein the briquette, when cured, contains about 0.05% to about 10% of the binder mixture.
A binder for use in the formation of briquettes from ferrous or ferro-alloy steel byproducts,
- the binder comprising:
- about 0.025% to about 30% of a polyvinyl alcohol resin;
- about 1% to about 20% of a phenolic resin;
- about 0.05% to about 5.0% of an ester-based hardener;
- and
- water forming a remainder of the binder.
