HEAT INSULATING SCREEN FOR INSULATION OF ELECTROMAGNETIC INDUCTOR, AND HEAT TREATMENT PLANT CONTAINING SUCH SCREEN Russian patent published in 2011 - IPC F27D11/06 C21D9/56 

FIELD: electricity.

SUBSTANCE: heat insulating screen permeable for magnetic flow and intended for heat insulation of electromagnetic inductor with cross or pseudo-cross field against radiation of heated item (1) is made in the form of matrix of bricks made from heat-insulating material and multiple tubes cooled by fluid medium circulated in them. At that, tubes are enclosed in brick matrix and together with bricks are installed on the bottom. Screen contains heat-conducting devices located behind bricks and intended to remove heat energy flow which passed through bricks; at that, heat-conducting devices are in thermal coupling with cooling tubes to remove heat energy flow in the direction of those tubes. There described is heat treatment plant containing such screen.

EFFECT: high heat protection of screen without notable increase of layer thickness of electrically insulating material.
