Embodiment

[0032] A manufacturing process of an iron core, comprising the following manufacturing steps: taking the following raw materials by weight ratio, silicon 3-5%, quartz 5-10%, coke 20-30%, steel scrap 60-80%; quartz, coke 1. Put the steel shavings into the blower after cleaning, and remove impurities after natural air drying; crush the quartz and coke into fine powder with a pulverizer, and put the steel shavings into the electric furnace for smelting after secondary removal of impurities. The smelting conditions are temperature 1300~2300℃ , the time is 1 to 3 hours, the smelted quartz, coke and steel chips are made into ferrosilicon; after the ferrosilicon is cooled, it is crushed and ground, the silicon is removed from impurities, crushed and ground, and then put into a powder mixer to make the raw materials uniform; The raw materials are put into the smelting furnace for smelting. The smelting conditions are temperature 1500~1600℃, and the time is kept for 2~2.5 hours to obtai...

Abstract

The invention relates to the field of iron core manufacturing, in particular to a manufacturing process of an iron core. The invention adopts silicon steel after removing impurities, so that the magnetic induction intensity (magnetic induction) is high under a strong magnetic field, which makes the iron core volume of a motor and a transformer smaller than that of the iron core. The weight is reduced and the raw materials are saved; the surface is smooth, flat and uniform, which can improve the filling factor of the iron core; the punching performance is good, which is more important for the manufacture of micro and small motors; Anti-corrosion and improved sheet punching performance; and the present invention has relatively simple manufacturing process and steps, lower requirements for production equipment, and the prepared iron core has a long service cycle, thereby reducing use and production costs.

Description

technical field [0001] The invention relates to the field of iron core manufacturing, in particular to an iron core manufacturing process. Background technique [0002] Commonly used transformer cores are generally made of silicon steel sheets. Silicon steel is a kind of steel containing silicon (silicon is also called silicon), and its silicon content is 0.8 to 4.8%. Silicon steel is used as the iron core of the transformer because silicon steel itself is a magnetic substance with strong magnetic permeability. In the energized coil, it can generate a large magnetic induction intensity, thereby reducing the volume of the transformer. [0003] For the iron core of the transformer, a cold-rolled silicon steel sheet with a thickness of 0.35 mm is generally used. According to the size of the required iron core, it is cut into long pieces, and then overlapped into a "day" or "mouth" shape. Theoretically speaking, in order to reduce eddy current, the thinner the thickness of the...
