Popular passages
Page 102 - The number of passes and speed of train shall be so regulated that on leaving the rolls at the final pass, the temperature of the rail will not exceed that which requires a shrinkage allowance at the hot saws. for a rail 33 feet in length and of loo-lb.
Page 102 - The bars shall not be held for the purpose of reducing their temperature, nor shall any artificial means of cooling them be used after they leave the finishing pass. Rails, while on the cooling beds, shall be protected from snow and water.
Page 103 - FINISHING: 505. (a) All rails shall be smooth on the heads, straight in line and surface and without any twists, waves or kinks.
