Abstract

The invention relates to the field of crucible products, in particular to a high-temperature forming system for a quartz crucible, and solves the problem that a thick-wall crucible cannot be manufactured by the conventional technical equipment. The high-temperature forming system for the quartz crucible comprises a crucible melting main machine, an oil immersed transformer, a hydraulic transmission system, a cooling system, a control system and an exhaust system, wherein the oil immersed transformer, the hydraulic transmission system, the cooling system and the control system are connected with the crucible melting main machine through an electric signal or a pipeline respectively. Through the design and bold and scientific technical reconstruction, the system fills in the blank of producing the thick-wall crucible.

Description

[0001] The present invention is a divisional application based on the patent application No. 200910141939.9 of "26-inch thick-walled deep-cavity quartz crucible, its production method and equipment" filed on June 10, 2009. technical field [0002] The invention relates to the field of crucible products, and relates to a high-temperature forming system for a quartz crucible. Background technique [0003] The old technology in the domestic chemical and glass industries uses platinum crucibles to melt raw materials, because the market price of platinum is relatively high, resulting in a substantial increase in corporate costs. Only quartz crucibles can replace platinum crucibles, because quartz crucibles have high purity and good stability , The price is low. In the past ten years, quartz crucibles have become the preferred container for melting raw materials in the chemical and glass industries. However, when melting glass and chemical raw materials, there are certain alkali ...
