| description | The invention provides a control method for full decarburization of silicon spring flat steel, which comprises the following steps of: performing mechanical shot blasting on a continuous casting billet before heating in a furnace to remove surface oxide scale, quickly heating in the furnace at high temperature in an oxidizing atmosphere, respectively descaling by using high-pressure water before and after rough rolling in a rolling process, quickly passing through a structure transformation two-phase region after finish rolling, and continuously rolling to obtain the silicon spring flat steel. Burners of the heating section I and the heating section II are both closed, the temperature of the heating section III is 1250 +/-20 DEG C, and the temperature of the soaking section is 1240 +/-20 DEG C; the total time for the continuous casting billet to enter and exit from the heating furnace is less than or equal to 95 minutes, and the total heating time in the heating section III and the soaking section is controll |
