Method for producing 1.5 mm checkered plate from common hot rolling production line sheet billet

The invention discloses a method for producing a 1.5 mm checkered plate through a common hot rolling production line thin slab, and belongs to the field of steel production, low-carbon, low-silicon and low-manganese components are adopted, a common hot rolling strip steel production line is used for production, the working procedures comprise slab heating, rough rolling, finish rolling, laminar cooling and coiling, in the slab heating process, the slab thickness is selected to be 90-105 mm, and the overall in-furnace time is controlled to be 70-140 min; the furnace temperature of the first heating furnace is controlled to be 750-900 DEG C; the furnace temperature of the second heating is controlled to be 1050-1130 DEG C, and the total in-furnace time of the first heating and the second heating is controlled to be 35-70 min; and controlling the temperature of the third heating furnace section and the soaking furnace section in combination with the in-furnace time. Compared with the prior art, the 1.5 mm checke
