摘要
Method for production of combined welded joints of hot-rolled strips made of alloy steel of type 20X4MT?? and steels 08, st3 of all degrees of deoxidization, which includes: selection of associated qualities of steels, surface preparation, determination of optimum section of hot-rolled strips of width exceeding 1000 mm, development of modes of welding and procedure of assembly of the etched strips into the enlarged rolls. The selection of the qualities of steels for combined welded joints of hot-rolled strips is achieved on the basis of conditions of guaranteeing the stability of the processes of etching and cold rolling in the set modes of the strips with a width exceeding 1000 mm, the development of optimum geometric parameters of the section of welded joints of hot-rolled strips includes wedging limitation - not more than 0.05 mm, transverse variation in thickness - maximal 0.06 mm, convexities of cross section - not are more than 0.05 mm.
