The application discloses a low-temperature pre-annealing production method of oriented silicon steel, and realizes the low-temperature pre-annealing production method by using a low-temperature pre-annealing furnace, and comprises the following steps: step 1, a vertical steel coil (4) is arranged in a furnace body (1) through a sealing device (3), a heating system (2) is used for heating the furnace temperature in the furnace body from normal temperature to a first temperature, the first temperature is greater than or equal to an MgO dehydration temperature, the furnace temperature is less than or equal to 950 DEG C, water in an MgO coating on a surface of the vertical steel coil is decomposed and discharged, and a cold spot (41) of the vertical steel coil reaches a temperature higher than the MgO dehydration temperature; and step 2, after the low-temperature pre-annealing is completed, a temperature difference between the cold spot and a hot spot (42) of the vertical steel coil is not more than a temperature difference threshold value, and subsequent high-temperature annealing production is carried out on the vertical steel coil. The application can break through the capacity limitation of a conventional high-temperature annealing process, greatly improves the yield on the basis of guaranteeing the production quality, and simultaneously improves the problem of poor production and process flexibility of the high-temperature annealing process.
