Provided is a method and an apparatus for transverse temperature distribution design of forming and annealing to enhance a draw rate, which relates to the technical field of glass substrate manufacturing. The method includes dividing a forming and annealing process of a glass substrate into an overflow zone, a thickness forming zone, a pre-annealing zone, a soaking zone, an annealing zone, and a subsequent annealing zone based on six physical flow characteristics of glass in an overflow forming annealing zone. Meanwhile, differentiated transverse temperature distribution strategies are adopted in different temperature control zones to achieve precise control over the transverse temperature distribution design for glass forming and annealing. Additionally, the mechanism involved in the glass annealing process is deeply analyzed using temperature difference-structural difference-thermal stress, providing a more scientific and reasonable method for the warpage size and curved shape of glass after annealing and cooling to room temperature. It is particularly suitable for the temperature distribution design of the forming and annealing zone of glass substrates with a large draw rate, a wide plate width, and a thin profile.
