    摘要: The present discloses a steel rail for high speed and quasi-high speed railways and a manufacturing method thereof. The steel rail having a superior rolling contact fatigue property can be obtained by reducing content of carbon in conjunction with controlled cooling after rolling. The steel rail includes 0.40-0.64% by weight of C, 0.10-1.00% by weight of Si, 0.30-1.50% by weight of Mn, less than or equal to 0.025% by weight of P, less than or equal to 0.025% by weight of S, less than or equal to 0.005% by weight of Al, more than 0 and less than or equal to 0.05% by weight of a rare earth element, more than 0 and less than or equal to 0.20% by weight of at least one of V, Cr, and Ti, and a remainder of Fe and inevitable impurities. The steel rail manufactured according to the method of the present invention maintains the strength and hardness of the existing steel rail for the high speed railways, while enhancing the toughness, plasticity and yield strength, and an energy value required for initiating and expanding microcracks formed at the surface of the steel rail due to fatigue is increased, and thus under the same conditions, the rolling contact fatigue property of the steel rail can be improved, thereby finally improving the service lifetime and the transportation safety of the steel rail.

    摘要: The present invention provides a roofing product comprised of an asphalt coating on a nonwoven fiberglass mat. Enhanced tear strength for the roofing product, generally an asphalt shingle, is obtained by the presence of a release agent. The release agent can be a coating on the fiberglass mat, an additive in the mat binder, or present as an additive in the asphalt itself. Preferably, the release agent is a reactive polysiloxane which can react with any component within the roofing product, including the glass surface, sizing chemicals, binder chemicals, as well as the asphalt coating. The reaction can take place either during or after the polysiloxane is added or applied.
