摘要

Method and element of a skid to reduce temperature difference heating plates and billets, and a set of "skid" that uses the same.The present invention relates to an improved method and an element of a skid for minimizing the temperature difference between a region of contact with skid and other regions in a material hotTo be heated, such as a plate or a billet in a reheating furnace and a set of "skid" that uses the same.The element of a skid has at least one ventilation channel for restriction of the heat transfer toward a lower portion of the element of a skid to support or transport the material quentAnd in the reheating furnace and allowing the passage of combustion gas using the same.To reduce the temperature difference between a region of contact and a region of contact of the hot stuff.The invention restricts the transfer of heat from the hot material to a cooling tube of a skid and introduces combustion gas in reheating furnace for the element of "skid" to compensau00e7u00e3The loss of heat in an upper portion of the element of "skid",Thereby avoiding a drop in temperature in a region of contact between a top face of the element of a skid and a lower side of the hot stuff,So that the capacity of rolling screw and the quality of hot material can be improved in processes subsequ00b3entes.
