Problems solved by technology

Therefore, the chrome-zirconium copper cooling roll must not have defects such as micro-shrinkage, pinholes, dust inclusions, cracks, etc. from the inside to the outside. This is a technical indicator that is difficult to achieve, otherwise it will affect the quality of the amorphous strip product.

Embodiment 1

[0025] Example 1: Φ1625 / Φ1470×360 chromium zirconium copper cooling roll

[0026] a. Material selection and ingredients Zr=0.4%, Cr=1.2%, the remaining copper (the total weight of the above materials is about 2.6 tons), Cr is added in the form of copper-chromium master alloy, and copper and copper-chromium master alloy are first added to the vacuum induction In the furnace, it is vacuumed and powered to melt. When the melting temperature reaches 1300°C, zirconium is added to melt and then cast an ingot.

[0027] b. Use the primary ingot as the electrode for secondary remelting. The flux is MgF30%, CaF70% binary slag agent, the weight is 150kg, and the diameter of the crystallizer is Φ520×1800. After the flux is melted, argon gas is injected into the crystallizer. First, the remelting voltage is 66V and the current is 6000A, and the secondary electrode is melted gradually. Power off after melting, melting ingot Φ500×1650.

[0028] c. Check the chemical composition of the ingo...

[0036] Example 2: Φ620 / Φ515×202 chromium zirconium copper cooling roll

[0037] a. Material selection and batching Zr=0.45%, Cr=1.%, the balance of copper (the total weight of the above materials is about 1 ton), Cr is added in the form of copper-chromium master alloy, first add copper and copper-chromium master alloy to the vacuum In the induction furnace, the vacuum is pumped and the electricity is melted. When the melting temperature reaches 1350°C, zirconium is added to melt and cast an ingot.

[0038] b. Use the primary ingot as the electrode for secondary remelting. The flux is MgF30%, CaF70% binary slag agent, the weight is 50kg, and the diameter of the crystallizer is Φ360×1800. After the flux is melted, the crystallizer is filled with argon gas. The remelting voltage is 66V and the current is 6000A. The secondary electrode is melted and gradually melted. After the power outage, the ingot Φ350.

[0039] c. Check the chemical composition of the ingot:

Abstract

The invention discloses a preparation method of a chromium-zirconium-copper cooling roll for an amorphous ribbon, which relates to a novel process of a chromium-zirconium-copper alloy material, more specifically relates to the preparation method of the chromium-zirconium-copper cooling roll for the amorphous ribbon. The invention provides the preparation method of the chromium-zirconium-copper cooling roll for the amorphous ribbon which can thoroughly overcome the loosening, air holes, slag, cracks and other defects of a chromium-zirconium-copper ingot, and solve the quality problem of the ingot. The preparation method comprises the steps of fusion casting, forging, high-temperature solution heat treatment, cold processing, aging heat treatment and machining.

Description

technical field [0001] The invention relates to a new process of a chromium-zirconium-copper alloy material, and more specifically relates to a manufacturing method of a chromium-zirconium-copper cooling roll for an amorphous belt. Background technique [0002] At present, the magnetic amorphous strip material produced in my country is a new type of energy-saving and environmentally friendly material, which can replace the silicon steel sheet in the traditional transformer. The use of magnetic amorphous strip material can improve the efficiency of the transformer, reduce and reduce the volume and weight of the transformer. , so it is a new energy-saving new material. [0003] The tool that must be used in the production of amorphous strips - chromium zirconium copper cooling roll is a key component that determines the quality and yield of amorphous strips. The application of chrome-zirconium copper cooling roll in the production of amorphous strip: that is, the molten steel ...
