Embodiment Construction
[0041] The technical solutions of the present invention will be further described in detail according to Examples A-H.
[0042] The high-strength steel sheet for glass lining of the present invention is manufactured according to the following steps (the chemical composition ratio of each steel strip in Examples A-H is shown in Table 1, and the detailed process parameters of the high-strength steel sheet for glass lining in Examples A-H are shown in Table 2):
[0043] (1) The molten steel is subjected to converter blowing and vacuum degassing treatment;
[0044] (2) Continuous casting or die casting, the die-cast steel ingots need to be rolled into billets;
[0045] (3) After heating the steel billet or cast slab at 1100~1250℃, carry out multi-pass rolling in the austenite recrystallization zone, the total reduction ratio is ≥50%, and the final rolling temperature is controlled to 800~920℃. For the thickness 2~18mm steel plates are rolled by hot continuous rolling mills, and for steel ...
