Abstract
The invention discloses a metal-ceramic thermal insulation feeding pipe capable of constraining glass fluid. The feeding pipe is composed of a corundum ceramic pipe and a metal pipe and is prepared by heating the metal pipe and then sleeving the metal pipe into the corundum ceramic pipe to tightly sleeve the two pipes together due to the different thermal expansion coefficients of corundum ceramic and metal. The external metal layer of the feeding pipe is hollow, the two external ends of the metal pipe are both connected to a metal connecting pipe, and the metal connecting pipes are arranged in the different sides of the metal pipe and used to convey the cooling water. The feeding pipe integrates the thermal insulation function of the corundum material and the cooling effect of cooling water together, reduces the heat loss, and protects the external metal layer at the same time.
