Abstract

The invention discloses a heat conducting oil circular cooling system made of for amorphous magnetic materials, comprising a heat conducting oil cooling roller, a cooling roller rotating shaft and a heat conducting oil cooling tank, wherein the two ends of the axis of the cooling roller rotating shaft are coaxially connected with a heat conducting oil input pipe and a heat conducting oil output pipe, the heat conducting oil cooling roller is provided with a heat conducting oil cooling passage for enabling the heat conducting oil input pipe and the heat conducting oil output pipe to communicatewith each other, the heat conducting oil input pipe and the heat conducting oil output pipe are connected with the heat conducting oil cooling tank, a liquid nitrogen cooling pipe is arranged in theheat conducting oil cooling tank, one end of the liquid nitrogen cooling pipe is connected with a liquid nitrogen input pipe located outside the heat conducting oil cooling tank, and the other end ofthe liquid nitrogen cooling pipe is connected with a liquid nitrogen output pipe located outside the heat conducting oil cooling tank. The heat conducting oil circular cooling system made of amorphousmagnetic material further improves the cooling efficiency of the cooling roller to improve the production efficiency of amorphous alloy magnetic strips.

Description

technical field [0001] The invention relates to the technical field of non-gold alloy magnetic strip processing equipment, in particular to a heat-conducting oil circulation cooling system for amorphous magnetic materials. Background technique [0002] Iron-based amorphous alloy magnetic material is an alloy material composed of iron, silicon, boron and other elements. Its high saturation magnetic induction, magnetic permeability, excitation current and iron loss are superior to silicon steel sheets. Iron-based amorphous alloy magnetic materials are usually prepared by single-roll rapid quenching method: firstly, the raw materials containing the constituent elements of the amorphous alloy are put into the furnace for melting and calcination, and then the fully fused amorphous alloy melt is poured into the On the cooling roll that rotates rapidly and has a low surface temperature, the molten amorphous alloy material is cooled rapidly after contacting the cooling roll to form ...

AI Technical Summary

Problems solved by technology

[0003] Conventional cooling rolls in the prior art are mainly water-cooled, and the cooling efficiency of water as a coolant is limited, so it is difficult to further improve the production efficiency of amorphous alloy magnetic strips; heat transfer oil is a more high-end coolant , which has more sensitive heat balance ability and stronger heat conduction ability than cold water
