The invention discloses a production process for blue glass, and relates to the technical field of blue
glass production. The process comprises the following steps: S1,
raw material pretreatment: respectively
grinding and
drying a basic glass
raw material, a coloring agent and a functional additive, and then mixing in sequence; s2, melting the mixture in a primary
melting furnace in a
reducing atmosphere, and adding a
reducing agent; s3, transferring the primarily
molten glass liquid into a main furnace, and stirring and clarifying in a
nitrogen-
oxygen mixed protective gas environment; s4, cooling the clarified glass liquid, and continuously stirring and homogenizing; according to the preparation method, the basic raw materials, the coloring agent and the functional additive are accurately proportioned, and control steps of staged mixing,
reducing atmosphere melting, multi-stage clarification and homogenization, float forming and the like are combined, so that synergistic improvement of high optical purity and excellent mechanical performance is realized. In the process, the purity, the
granularity, the charging sequence and the thermal regulation of the raw materials are strictly controlled, so that the component uniformity and the product consistency are guaranteed.
