3/4-CONTINUOUS BROAD-STRIP MILL FOR CONTINUOUS ROLLING OF LOW-CARBON STEEL THIN STRIPS Russian patent published in 2013 - IPC B21B1/26 

FIELD: process engineering.

SUBSTANCE: invention relates to metallurgy. Proposed mill comprises heating kilns, slab width reduction press, set of roughing stands, intermediate rewinder, end cutting shears, machine for bonding and welding of breakdown, trimmer, edge heater, scale removing device, set of continuous finishing stands, strip cooling system, divider shears, clamps and reels. Proposed mill comprises looping tables with heat shields mounted at, at least, two penultimate interstand spaces of finishing set. Note here that magnitude of said spaces and loop reserve are set to comply with the conditions of complete termination of primary recrystallisation while last interstand space is defined in compliance with the sum of strain cold work at last stand for two completing reductions. At the start of run-out table arranged are the loop table with heat shields and pull rollers to allow strip reserve ahead of cooler for complete primary recrystallisation.

EFFECT: optimised thermal and strain conditions.
