Platinum channel installation method considering expansion characteristic and platinum channel

Abstract

The invention discloses a platinum channel installation method considering the expansion characteristic and a platinum channel. The method comprises the steps that a throat pipe is installed at a molten glass outflow hole of a glass kiln, a heating clarification section is built and installed, so that the heating clarification section is communicated with the throat pipe, a masonry stirring feeding section is installed, so that the stirring feeding section is communicated with the forming equipment, and meanwhile, a reserved position is reserved between the stirring feeding section and the heating clarification section, a cooling section is installed at the reserved position, an expansion reserved gap is reserved between the cooling section and the heating clarification section, and the cooling section and the stirring feeding section are welded together. The method is used for installing the platinum channel, the installation technology and process of the platinum channel in the installation process can be more accurate, and the expansion size needing to be reserved is more accurate and controllable. The technical requirements of high-quality glass kiln construction are met.

Description

Technical field[0001]The invention belongs to the technical field of glass furnace engineering construction, and specifically relates to a platinum channel installation method that takes into account expansion characteristics and a platinum channel.Background technique[0002]Nowadays, in the field of glass manufacturing industry, the liquid crystal glass substrate is a basic component of the liquid crystal display, and the liquid crystal glass substrate is also an important part of the liquid crystal display.[0003]The manufacturing process of the liquid crystal glass substrate mainly includes the furnace process, the platinum channel process, the forming process, the finished product process and the packaging process. First, in the furnace process, the raw materials for preparing the liquid crystal glass substrate are melted into a liquid state to obtain the glass liquid. In the platinum channel process, the platinum channel is used to clarify and homogenize the molten glass. Then, i...

Problems solved by technology

And when platinum is installed, it does not fully consider which direction the platinum will expand and elongate when it heats up and expands, nor does it consider the refractory material that is close to the platinum when it expands, and the steel structure connecting equipment connected to the platinum, etc., and other accessories The mutual friction and interference of equipment cannot guarantee that the platinum pipe can expand freely when the temperature rises in the later stage, and there may also be problems and hazards caused by installation, and the technical requirements and accuracy of the installation process cannot be well guaranteed

Moreover, the original technology only considers the butt welding process of platinum pipes in a high-temperature thermal state after the platinum expansion is completed.

However, under high-temperature field conditions, field operators and technical personnel cannot accurately align the two sections of platinum pipes, and cannot guarantee that the welding process technology meets the precision requirements.

And under high temperature and light conditions, it is not easy to fully check and confirm after welding

In the prior art, the platinum channel is usually installed in a simple connection welding method, and the installation process is imprecise, which hinders the improvement of the quality of glass production
