Glass continuous melting furnace and melting method

Abstract

The invention discloses a glass continuous melting furnace and a melting method, and belongs to the technical field of optical glass melting production. The furance mainly solves the problem that theproduction efficiency is affected due to the fact that the stripe homogenization efficiency and the bubble clarification efficiency are limited in the continuous smelting process. The furance is mainly characterized by comprising a melting crucible, a homogenizing crucible, a clarification tank and a working crucible which are made of platinum, and a first communicating pipe, a second communicating pipe and a third communicating pipe which are connected amoung the melting crucible, the homogenizing crucible, the clarification tank and the working crucible, wherein the homogenizing crucible andthe working crucible are respectively provided with a homogenizing partition plate and a homogenizing rod which are made of platinum, a clarifying partition plate is arranged in the clarification tank, and a negative pressure stabilizer is arranged at the upper part of the clarification tank. The furnace has the characteristics that the stripe dissipation efficiency and the bubble floating efficiency in the optical glass smelting process can be effectively improved, and the comprehensive production efficiency is improved, and the furnace is mainly used for improving the production efficiencyof the optical glass continuous smelting furnace.

Description

technical field [0001] The invention belongs to the technical field of optical glass smelting production. Specifically relates to a continuous glass melting furnace and a melting method. Background technique [0002] In recent years, with the advancement of science and technology and the improvement of living standards, people have higher and higher requirements for optical products. The development trend of optical systems such as imaging, detection, and sighting is to continuously pursue high-definition products, and the transmittance It is a key parameter that affects the experience of end customers. Therefore, the market has put forward higher and higher requirements for the transmittance of optical glass as the core component of the optical system. In addition, the existing optical glass continuous melting equipment is divided into two types in terms of crucible material: porcelain platinum continuous melting furnace and full platinum continuous melting furnace, and th...
