Problems solved by technology

Therefore, the longer the refueling time, the greater the loss to the production unit
[0020] Nowadays, melting furnaces are all developing towards large scale. Small melting furnaces are not allowed to be rebuilt due to the needs of energy saving and emission reduction and the restrictions of national policies. The market for colored glass has the characteristics of various types of demand, and the demand for a single type is not large. Furnaces cannot adapt to the needs of this market

Embodiment

[0048] A float glass melting furnace with a production capacity of 550 tons. The melting furnace includes a feeding tank 1, a melting part 2, a neck 3 and a cooling part 4; the cooling part is connected to the tin bath via a flow channel 5 ; The neck is a narrowed kiln pool between the melting part and the cooling part. It is used in conjunction with the low chute and hanging wall to separate the gas space and the molten glass between the melting part and the cooling part; Lengthen, the neck is 9m long and 5.5m wide; the neck is used as the feeding and mixing part, and the neck is divided into feeding zone 6 and mixing zone 7; the front part of the neck is feeding zone 6, and the feeding zone 6 is provided with The feeding channel 8 of the coloring material; the feeding channel penetrates the top of the furnace and the neck, and the feeding channel 8 is preferably designed as an upper and lower flat type, so that the added coloring material can be more evenly scattered on the gl...

Abstract

The invention relates to a melting furnace for producing float glass and a colorant addition method, belonging to the technical field of glass production. According to the invention, a neck (3) is used as a charging and mixing part; and coloring materials are added into molten glass via a charging channel (8) arranged at the charging area (6) of the neck. Since the melting furnace is filled with colorless basic molten glass, the operation of coloring is performed at the neck, thereby reducing displacement amount of the molten glass and effectively shortening changing time of the molten glass; and the method enables large-size melting furnaces to adapt to features of color glass demand market, and the features of the color glass demand market include demands for various varieties and little demand for a single variety.

Description

Technical field [0001] The invention belongs to the technical field of glass production, and specifically relates to a melting furnace for producing float glass and a coloring agent adding method, and is particularly suitable for the production of small batches and multiple varieties of bulk colored float glass. Background technique [0002] As a basic material, float glass has a wide range of applications in the construction, decoration, and automotive industries. In the current float glass production, the basic structure of the furnace used is as follows figure 1 As shown, along the length of the kiln body, it is divided into a feeding tank 1, a melting part 2, a neck 3, and a cooling part 4; the rear end of the cooling part is a runner 5 connected to the tin bath. In production, the mixed raw materials (referred to as batch materials) are put into the feeding tank 1 with a feeding machine. The melting part 2 is the part where the batch materials are melted and the glass liquid...
