Split cooler for a steel mill

Abstract

A cooler that is easily dis-assembled is disclosed here. The cooler has two halves which co-operate together to form a cooling passage way to cool a steel work product as it passes through the cooler. A pair of tubular half sections are fastened to each half section to expose the passage way when the two halves are separated. A steel work product normally passes through this passage way. If the steel work product should break during a rolling process then the cooler is removed and opened for inspection. If a piece of the steel work product is present in the exposed passage way it is easily removable and the cooler is reassembled and the rolling process begins

1 . A cooler for a steel mill in which substantially similar hollow shells are clamped together to which are secured sections of cooling tubes for the passage of cooling water there through, where said cooling water impinges on a work product passing through said tube sections and which is cooled by the exiting of cooling water passed through said cooling tube sections,
 said cooler being dismantable so that said cooling tube sections become accessible in said dismantled cooler so that clearing of the passageway said tube sections is facilitated.   
     
     
         2 . A cooler as claimed in  claim 1  wherein there are two shells in said cooler. 
     
     
         3 . A cooler as claimed in  claim 2  wherein said tube sections have a number of slanted openings therein to permit cooling water to exit upon said work product. 
     
     
         4 . A cooler housing a tubular enclosure extending the length of said cooler, said tubular enclosure having an interior and an exterior and comprising at least two parts,
 said tubular enclosure being separable along its length into two half tubes so that the interior of said tubular enclosure may be exposed when said tubular enclosure is dismantled,   each half of said tubular enclosure having a plurality of slots formed therein, and a source of coolant supplied to the exterior of said tubular enclosure for passage through said slots,   and said cooler is supplied with suitable container means for housing said tubular enclosure.   
     
     
         5 . A cooler as claimed in  claim 4  wherein said tubular enclosure has an entrance end and an exit end for the passage of a hot steel work product there through. 
     
     
         6 . A cooler as claimed in  claim 4  in which the slots in the parts of the tubular enclosure are slanted with respect to the longitudinal axis of said tubular enclosure. 
     
     
         7 . A cooler as claimed in  claim 4  wherein said container comprises two parts and said tubular enclosure is mounted in and supported by said container. 
     
     
         8 . A cooler to be used in a metal reducing steel mill comprising a container being constructed of at least two parts, a tubular enclosure separably joined along the longitudinal axis, mounted in said container parts,
 said tubular enclosure having entrance and an exit apertures which coincide with openings formed in said container,   and slots being formed in said tubular enclosure,   said slots being skewed with the longitudinal axis of said tubular enclosure, and,   coolant being circulated in the space existing between said container and said tubular enclosure, said coolant passing through said slots of said tubular enclosure,
