Embodiment Construction

[0008] The present invention will be further described below in conjunction with accompanying drawing.

[0009] The iron-based amorphous raw materials are smelted into alloy ingots, chemically analyzed, and the molten steel is poured into the tundish (about 1300°C), and the molten steel enters the nozzle pack (about 1200°C) from the tundish, and then flows into the high-speed rotating cooling roll from the nozzle pack On, rapidly cooling to form an amorphous thin strip, finished product inspection.

[0010] in,

[0011] 1. The chemical composition of molten steel when tapping is completed by chemical analysis before the furnace. Tapping temperature control is controlled by fast thermocouple.

[0012] 2. The stability of the liquid level of the nozzle package affects the thickness and density of the amorphous strip. The closed-loop control of steel replenishment from the tundish to the nozzle package makes the liquid level of the nozzle package fluctuate at about ±2mm.

Abstract

The moving process of producing amorphous belt includes the following steps: smelting alloy ingot with amorphous iron-base material, chemical analysis, pouring molten steel into pouring basket, making molten steel enter to nozzle ladle, making molten steel flow to cooling roll in high speed rotation for chilling to form thin amorphous belt, and product inspection. The amorphous belt has no crystal, excellent magnetic, electric, chemical and mechanical performance, short production process, low production cost and other advantages.

Description

technical field [0001] The invention relates to an amorphous metal production method in the metallurgical industry, in particular to an amorphous mobile belt-making production method, which adopts a new technology of liquid metal quenching technology. Background technique [0002] The production process of the traditional metallurgical production of soft magnetic materials is: from raw materials to smelting and then forging, hot rolling, cooling, then cold hardening annealing, and then cold rolling... etc., especially the thin strips used on high-frequency devices Requires repeated cold rolling, cold hardening and annealing. Therefore, the traditional production process is long and the production process is difficult to control. Especially the investment is large and the production cost is high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a production method of amorphous mobile belt, which adopts the new te...
