Abstract

A soft contact type non-groove crystallizer for electromagnetic conticasting of steel is composed of the sleeve pipe of crystallizer, casing and induction coil. Its sleeve pipe is composed of the lower copper (or Cu-ally) segment and the upper segment made of Cu-base composite. Its advantages are high and uniform magnetic penetrability, good cooling effect, high strength and thermal deformation resistance, and high P/C ratio.

Description

technical field [0001] The invention belongs to the technical field of metallurgical continuous casting, in particular to a slitless crystallizer for soft contact electromagnetic continuous casting. Background technique [0002] At present, the electromagnetic casting process of aluminum and copper has become more and more mature. Compared with the traditional DC method, the surface quality of the billet has been significantly improved. Due to the high density of steel, the required electromagnetic thrust is large; the electrical conductivity is small, and the generated electromagnetic thrust is small, so it is difficult to completely realize the moldless electromagnetic continuous casting. Inspired by the electromagnetic casting technology of aluminum, the French scholar Ch.Vives proposed to apply an AC electromagnetic field outside the continuous casting mold, and use electromagnetic pressure to make the molten steel and the mold solidify under the condition of "soft-conta...
