Process for preventing glass from rainbow emergence, and material feeding apparatus thereof

Abstract

The invention relates to a process for preventing glass from rainbow emergence. According to the process, 150-400 g of pig iron with purity of 99.9% is divided into 7-9 equal parts of iron sheets, the iron sheets are poured into a material feeding apparatus, and with the material feeding apparatus, 7-9 iron sheets with the weight of 150-400 g and the purity of 99.9% are uniformly pushed into a tin liquid within every 1 h. According to the present invention, the excessive reaction of the tin liquid and the pig iron is completely solved; and the material feeding way is changed, such that the tin liquid and the pig iron are not subjected to the excessive reaction, no gas bubble is generated, and the irregular pits appearing due to the gas bubble problem are solved.

Description

technical field [0001] The invention relates to the field of float glass, in particular to a production process and a feeding device for preventing rainbows from appearing in the glass. Background technique [0002] At present, an existing technique for preventing rainbows in glass is to throw 400 grams of pig iron into the tin bath at one time. At this time, the excessive reaction between the liquid tin in the tin bath and the iron will produce certain bubbles. When this batch When bubbles appear, when the glass floats over the tin liquid, the bubbles will push out irregular small pits on the lower surface of the glass. At this time, the glass produced is a defective product and cannot be used on automobile glass. Contents of the invention [0003] The purpose of the present invention is to aim at the existing technology for preventing glass from appearing rainbows, which is to throw 400 grams of pig iron into the tin bath at one time, at this time, the excessive reacti...
