Float process apparatus and method related to melting furnace with two production lines

Abstract

The invention relates to the technical field of float-process glass production, and in particular relates to a float-process glass production apparatus and method related to a melting furnace with two production lines. The method is characterized by employing the production lines branched vertically and transversely and comprising the following steps of: (1) feeding the melted and clarified glass liquid into the cooling part of a melting furnace, and then entering into horizontal production lines at the left and right sides through stream guidance at a triangular region under the action of vitreous humour convectio; (2) entering the glass liquid at the left side into a first tin bath through a first flow channel and forming, while entering the glass liquid at the right side into a second tin bath through a second flow channel and forming; and (3) conveying the formed glass plate at the left side to a first annealing furnace and a first cold-end cutting device through a first transition roller table, thereby obtaining a finished product; and conveying the formed glass plate at the right side to a second annealing furnace and a second cold-end cutting device through a second transition roller table, thereby obtaining a finished product. Compared with the existing longitudinally parallel branched production lines, the production lines branched vertically and transversely are smoother for the liquid to flow and guarantee the uniformity of the glass liquid and appropriate cooling strength.

Description

[technical field]

[0001] The invention relates to the technical field of float glass production equipment, in particular to a float glass production process equipment and a production method in which one melting furnace has two production lines. [Background technique]

[0002] Glass manufacturing has a history of 5,000 years. In the traditional sense, the production process of glass generally goes through stages such as raw material preparation, glass melting, glass product cooling and forming, and glass product annealing. The equipment involved includes melting furnaces, Tin baths, annealing furnaces and cutting devices.

[0003] The "one kiln and one line process" of the traditional craft, that is, a melting furnace, the cooling part of the melting furnace is connected with a tin bath through a flow channel, and the tin bath is connected with the subsequent annealing kiln through a transition roller table, and the cold end cutting equipment is connected behind the annealin...
