Method for manufacturing hot rolled steel strip for vehicle component, involves enabling mixing of alloy constituents of steel melts in contact regions of steel melts during hot-rolling process to form composite cast portion

摘要

#CMT# #/CMT# The method involves circulating steel melts (8) of different alloy composition on casting tapes (5) of independent systems (A,B) subsequently and solidifying the steel melts on casting tapes in hot-rolling process. The casting tapes of the independent systems are arranged in parallel. The alloy constituents of the steel melts are mixed in contact regions of the melts during hot-rolling process to form a composite cast portion. #CMT# : #/CMT# An independent claim is included for hot rolled steel strip. #CMT#USE : #/CMT# Method for manufacturing hot rolled steel strip (claimed), used in casting plant for manufacture of vehicle component. #CMT#ADVANTAGE : #/CMT# The material properties and cross-section of the steel tape can be adjusted favorably and logistic expenditure required for provision of the steel melts can be reduced. Location-specific properties of the steel strip can be realized efficiently. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic diagram of the independent systems in casting plant. 1 : Fusion vessel 3 : Runner 5 : Casting tapes 8 : Steel melts A,B : Independent systems.
