Platinum channel non-heating area thermal state maintenance method

Abstract

The invention relates to the technical field of glass production, in particular to a hot-state maintenance method for a platinum channel, and more particularly relates to a hot-state maintenance method for a non-heating section of a platinum channel body, so as to change the current situation that the platinum channel body cannot be maintained in a hot state in the prior art. Comprising the following steps: additionally arranging a heating device on a heating section of a platinum channel; separating the hot repair section of the platinum channel from the muffle furnace; after the temperature of the glass liquid is reduced, an outlet of the platinum channel is cooled through external cooling; increasing the power of a heating section of the platinum channel and starting a heating device at the same time when the glass liquid in the platinum channel is static; and the platinum channel of the hot repair section is cooled, cleaned, positioned, welded and checked. According to the invention, non-disassembly type maintenance is carried out in a thermal state, thermal state repair can be carried out on defects existing in design, continuous leakage of molten glass at a damaged part is avoided, bubbles and other defects introduced in the leakage process of the molten glass are avoided, and erosion of the leaked molten glass and a refractory material is avoided.

Description

technical field [0001] The invention relates to the technical field of glass production, in particular to a method for hot-state maintenance of a platinum channel. Background technique [0002] With people's continuous pursuit of living materials, the quality requirements for special glass and medical glass are also constantly improving, and such high-end glass also uses platinum channels. Platinum channels are generally composed of platinum body and peripheral refractory materials and steel structures. , and the platinum body is made of precious metal platinum and its alloys, which has many advantages such as high temperature resistance, corrosion resistance, and little pollution to the glass liquid. In use, the platinum channel is generally divided into a heating area and a non-heating area. Specifically: the heating area refers to passing the current to the platinum pipe and using the resistance of the platinum pipe to heat it, so there are more insulation materials aroun...
