Description
Technical field
The present invention relates to a kind of glass melter, especially a kind of glass melter that is used to produce two kinds of low iron sheet glass.
Background technology
Formed from plate glass technology is very ripe, and the melting furnaces melting capacity is very big, and the moulding process in usefulness has two kinds at present.A kind of is the float glass process moulding process; Changeable to the glass metal demand, demand is big when producing heavy sheet glass, and demand was little when production approached glass; All be that melting furnaces are connected a float glass process moulding process production line; Basic working procedure is that raw materials mix, the fusing of melting furnaces melting end, the cooling of melting furnaces cooling end, tin groove forming, annealing furnace annealing, cold junction cutting are got sheet, is used to produce ordinary plate glass, and product is a parallel transmitted light glass; Another kind is the rolling press moulding process; Less to the glass metal demand; Mostly be that melting furnaces are connected many rolling press moulding process production lines; Basic working procedure is that raw materials mix, the fusing of melting furnaces melting end, the cooling of glass metal path, rolling press moulding, annealing furnace annealing, cold junction cutting are got sheet, is used to produce embossing plate glass, and present product all is a diffusing glass.
In the sheet glass kind, can be divided into two kinds by the glass iron level, a kind of is ordinary plate glass, is produced by the float glass process moulding process, product is mainly used in building, automobile, daily etc.; Another kind is a low iron content glass, and the product light transmission improves, thereby the ultra-clear glasses that is otherwise known as, and is produced by the rolling press moulding process, and product is mainly used in the euphotic cover plate of solar power-generating facility.
Float glass process moulding process and rolling press moulding process are all very ripe, and it is stable that process system has kept, but mold temperature is different; The float glass process mold temperature is 1150 ℃; The calendering formation temperature is 850 ℃, so float glass process forming production line and rolling press forming production line are always separate production line.
Summary of the invention
The objective of the invention is in order to overcome the defective that float glass process forming production line and rolling press forming production line are always separate production line, and a kind of glass production line that is used to produce two kinds of low iron sheet glass is provided.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of glass melter that is used to produce two kinds of low iron sheet glass; Comprise glass melter and the card neck that is connected with melting furnaces; It is characterized in that: the exit end at card neck connects a glass solution to both sides mobile horizontal passageway; On horizontal passageway, connect a glass solution mobile branch flow passage at least, the port of each branch flow passage is connected with the rolled glass forming production device; On horizontal passageway, at least also be provided with a heating unit, each connects a glass solution mobile runner at the corresponding horizontal passageway place of heating unit, and the port of each runner is connected with the float shaping production equipment.
On the basis of above-mentioned main technical schemes, can increase following further perfect technical scheme:
Preferably be chosen in a heating unit is set on the horizontal passageway, heating unit is positioned on the horizontal passageway with the shortest glass metal of card neck port path.
Preferably be chosen in the horizontal passageway two ends glass solution mobile branch flow passage is set respectively.
The bottom of described horizontal passageway is lower than the bottom of horizontal passageway and branch flow passage junction, and the width of horizontal passageway is wider than the width of horizontal passageway and branch flow passage junction.
The cooling end of melting furnaces in the beneficial effect cancellation floating process of the present invention; Between melting furnaces melting end and runner, increase a glass metal path; On the shortest glass metal path; Thin flat plate glass float glass process moulding process production line is set, and the auxiliary mold temperature that improves of heating unit is set on the glass metal path, to guarantee the float glass process mold temperature; The longer heat radiation of glass metal path is more, the calendering formation temperature is low more, on longer glass metal path, rolling press moulding process production line is set, with glass metal path length regulation and control moulding rolling press temperature; Be lower than the clarification that the effected glass metal is wider than out in outlet, glass metal duct width with glass metal path bottom, to realize two kinds low iron sheet glass of a glass melter production.
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Description of drawings:
Fig. 1 is a front view of the present invention.
