摘要： A rail weld treatment device improves a resulting microstructure in and around an effected zone of a rail weld and of rails surrounding the rail weld. The device includes, but is not limited to a fixture clamping and centering assembly for engaging a rail head of a rail and a heating and cooling device connected with the fixture clamping and centering assembly to be positioned over the rail head. The fixture damping and centering assembly comprises an engagement member which removably engages the railhead. The heating and cooling device includes a heating member for heating an effected zone of the rail weld and a cooling member for cooling the effected zone.

摘要： A railroad rail (120) produced by rolling a substantially round bloom (102), together with a system for manufacturing the same. The round bloom (102) may be produced by continuous casting methods. The bloom is initially rolled into a substantially rectangular shape (103) and then into a rail (120). The rolling process may be continuous and in-line to allow for the production of very long seamless rails.

摘要： A unitary one quarter mile long railroad rail and system and method for manufacturing the same. The unitary rail eliminates the problem of weld seams in the one quarter mile long sections of rails which are transported to the installation site. The method of manufacture is characterized by the use of a continuous rolling process and the in-line controlled cooling of the rail.
