Steel Wire Patenting Process. The annealing and patenting lines are used to heat treat the wire in order to re-establish the original grain structure of the steel so that the wire can be further processed to make thinner products. Patenting consists of passing the wire through tubes in a furnace at about 970 o C. The patenting process first involves heating the wires in an austenitizing furnace usually direct fired or muffle tube to about 950C in order to form a uniform austenite structure of largish grain size. In steel drawing process the annealing process is also called patenting.
The process involves an in-line heat treatment at 970 degrees Fahrenheit and then cooled in a variety of mediums including air and lead. Patenting is a heat treatment process that improves the durability and strength of the wire. The fine-grained structure so formed patenting sorbite has high strength coupled with good ductility. Wire drawing is usually performed cold although there are some cases where steel rodwire is drawn hot to improve ductility. Wire ropes for haulage purposes are usually made from carbon steel wires ranging from 035 to 05 carbon and before drawing the material is subject to a heat-treatment known as patenting. This fully pearlitic structure in hypereutectoid steel wires are obtained by a special heat treatment process called lead patenting process.
Patenting is a heat treatment process that improves the durability and strength of the wire.
Wherein said steel wire consists essentially of about 9661 to about 98905 weight percent iron from about 072 to about 104 weight. The two aqueous polymer quenchants used as alternatives for lead baths. The patenting process developed in England involves running high-carbon steel wires through tubes in a furnace heated to a temperature of 970 F then rapidly cooling the wire in air or molten lead. This invention discloses a process for producing a high strength filament said process comprising the steps of. Wire ropes for haulage purposes are usually made from carbon steel wires ranging from 035 to 05 carbon and before drawing the material is subject to a heat-treatment known as patenting. To about 1100 C.
