The invention belongs to the technical field of metallurgy and steel rolling, and relates to a production method for hot-rolled oriented silicon steel, in particular to a method for cross-rolling and manufacturing hot-rolled oriented silicon steel by means of a heat-preservation pit and a single heating furnace. According to the method, the heat-preservation pit specially for the silicon steel is utilized for conducting heat-preservation buffer on oriented silicon steel casting blanks manufactured in a steelmaking continuous casting mode; the oriented silicon steel is heated by adjusting and arranging a production plan designedly and by means of the single heating furnace, namely, a heating furnace specially for the silicon steel; and during rolling, the oriented silicon steel is classified into different rolling units, and the oriented silicon steel meeting rolling requirements and steel in ordinary heating furnaces are cross-rolled in the form of the rolling units. The silicon steel blanks are subjected to
