The material of the iron core of the fixed rotor core ignition coil is very hard, so it is very difficult to cut. It is necessary to master certain cutting methods to cut easily. The following is a simple understanding of the iron core of the fixed rotor core ignition coil. Oxygen cutting method:
Why should the ignition coil of the motor iron core go through the forging process?
Forging production is one of the main processing methods for the supply of mechanical parts in the iron core industry. The following for everyone to explain why the motor core through the forging process.
Through forging, not only can the shape of the mechanical parts be obtained, but also the internal structure of the metal can be improved and the mechanical and physical properties of the metal can be improved. For important mechanical parts with high stress and high requirements, most of them are manufactured by forging production methods. For example, important parts such as steam turbine shaft, rotor, impeller, blade, guard ring, large hydraulic press column, high-pressure cylinder, rolling mill roll, internal combustion engine crankshaft, connecting rod, gear, bearing, sleeve, etc., are all used for forging production.

　　This is the most basic condition for the gas cutting process to proceed normally. If the melting point of the fixed rotor core is lower than its ignition point, the fixed rotor core will first melt when preheated, and the temperature will no longer rise, so that under the action of cutting oxygen, The combustion process will not occur. Pure iron, low carbon steel and low carbon alloy steel with less alloy elements can meet this condition and therefore have good cutting performance. With the increase in carbon content, the melting point of steel decreases and the ignition point increases. For example, a high-carbon steel with a carbon content of 0.70 % has a melting point that is basically equal to the ignition point. Therefore, steel with a carbon content greater than or equal to 0.70 % is used. Gas cutting is more difficult. Aluminium, copper, cast iron and other materials have a burning point higher than the melting point, so they can not be cut using ordinary oxygen cutting methods.
Only in this way can the liquid liquid liquid oxide slag be blown away so that the cutting process continues. Otherwise, the high-melting point oxide will cover the incision in a solid state, hindering the oxidation of the rear material and making the cutting process difficult. For example, the oxide melting point of materials such as high-chromium steel, chrome-nickel rotor core, aluminum and aluminum alloy are all higher than the melting point of the material itself, and therefore can not be cut by oxygen cutting.
About why the motor core ignition coil iron core should go through the forging process, this is the first introduction here, please continue to pay attention to this website, we will continue to share it for you.
