Abstract
The present invention provides a method of producing cast steel railway wheels. After pouring and removal from the mold, the steel wheel is processed in various steps including processing in an annealing and a tempering furnace. The wheel is then passed through a wheel cooling tunnel where the wheel is cooled from approximately 900.degree. F. to about ambient temperature.
Claims5
A method of producing a cast steel railway wheel comprising the steps of assembling a mold by placing a cope section on a drag section and moving said assembled mold to a pouring station,
- pressure pouring molten steel upwardly through a pouring tube into said assembled mold,
- moving said filled assembled mold to a mold disassembly station where said cope section is removed and said cast steel railway wheel is removed from said drag section,
- removing sprues from said cast steel railway wheel,
- annealing said cast steel casing steel wheel in a beat treatment furnace,
- rim treating said cast steel railway wheel in a water spray operation,
- tempering said cast steel railway wheel in a draw furnace,
- hub treating said cast steel railway wheel in a water spray operation,
- cooling said cast steel railway wheel in a cooling tunnel by moving said cast steel railway wheel through said cooling tunnel in about two hours while moving air through said cooling tunnel at a rate sufficient to cool said cast steel railway wheel from a temperature of about 900.degree. F. when entering said cooling tunnel to near ambient temperature when exiting said cooling tunnel wherein the cooling tunnel comprising a plurality of fans for cooling the said wheel.
