Method for preparing high-silicon silicon steel ribbon by hot dipping silicon method and continuous preparation device of silicon steel ribbon

Abstract

The invention discloses a method for preparing a high-silicon silicon steel ribbon by a hot dipping silicon method. A standby basis ribbon is transmitted and enabled to pass through hot dipping solution in a hot dipping tank, so that a hot dipping high-silicon plating layer is covered on the surface of the standby basis ribbon, the thickness and surface evenness of the hot dipping high-silicon plating layer are modified and controlled to obtain a high-silicon composite plate steel strip blank, and then uniform radiating treatment is carried out to continuously prepare a high-silicon steel ribbon with uniformly distributed silicon elements. The invention also discloses a continuous preparation device of silicon steel ribbon, which comprises an unreeling guide device, a preheating furnace, a plating solution continuous supply device, a hot dipping device, a radiating heat treatment device and a wrapping device which are arranged according to the precedence order of the processes. According to the method, the low-silicon steel ribbon rapidly passes through the high-silicon solution to plate a high-silicon plating layer, and the high-silicon silicon steel ribbon with excellent magnetic property is obtained through heat treatment. The method is simple to operate, and has the characteristics of high efficiency and capability of preparing continuously, and the preparation cost can be greatly reduced.

Description

technical field [0001] The invention relates to a metal material preparation process and equipment, in particular to a silicon steel strip preparation process and device, which are applied in the technical field of continuous silicon steel strip manufacturing. Background technique [0002] Silicon steel, also known as electrical steel, is an important magnetic material used in the electric power and telecommunications industry to manufacture generators, motors, transformers, transformers, relays and other electrical instruments. As we all know, the silicon content in silicon steel sheets has a great influence on the characteristics of its products, such as the obvious influence on the magnetic induction intensity and iron loss. Studies have shown that: with the increase of silicon content, the resistivity of silicon steel sheet increases, and the eddy current loss decreases, thus showing excellent magnetism at higher frequencies. When the silicon content in silicon steel she...

Problems solved by technology

In the process of hot-dip galvanizing, a sinking roll needs to be placed in the zinc bath as a non-drive turning roll. The temperature of hot-dip galvanizing is generally 440-460°C, and the requirements for the material of the sinking roll are not very strict. However, in more It is very difficult to hot-dip high-melting-point substances at high temperatures to obtain the required materials, especially for functional materials that have very strict requirements on material purity. At the same time, the relative sliding between the sinking roll and the strip will cause friction and scratches on the surface of the steel. It will also seriously affect the surface quality of the strip

It can be seen that there are still many technical problems to be solved in the process and equipment for continuous preparation and large-scale production of high-quality high-silicon steel sheets, and there is still a lack of effective means for low-cost preparation of high-silicon steel sheets
