Aluminum Chrome Intermediate Alloy Aluminium Chrome Alloy

Product Description

Hot coil continuous annealing pickling method of Fe-Cr aluminum alloy, including: material preparation, selection of Fe-Cr aluminum alloy hot coil thickness of 1.5mm ~ 6.0mm, width of 200mm ~ 2500mm and coil weight more than 1 ton; Head and tail riveting, hot coil iron chromium aluminum alloy after the hot coil head and tail and welded stainless steel plate respectively head riveting and tail riveting, riveting after rolling; Continuous annealing and pickling, the ferrochrome aluminum hot coil riveted to the head and tail of the stainless steel plate transported to the continuous annealing pickling line, the first coil uncoiling, riveted to the head of the stainless steel plate and the lead strip welding, directly over the line for heat treatment and pickling, from the second roll, the stainless steel plate riveted to the head of the hot coil and the stainless steel plate riveted to the tail of the hot coil welding, and then continuous over the line for heat Treatment and pickling. By using the method of the invention, the hot coil of Fe-Cr aluminum alloy can be operated quickly on the continuous annealing and pickling line to avoid the brittle break of the hot coil, and the hot coil can meet the requirements of cold rolling after annealing and pickling.
