Vacuum melting or non-vacuum melting technology is used to melt raw materials into alloy molten steel and ensure the purity of molten steel. The raw materials should meet the relevant standards, and the proportion of chemical components should be strictly controlled during the melting process.
2.Ingot casting.
The molten steel obtained from smelting is poured into the ingot mold and cooled to obtain the ingot. The size and surface quality of the ingot should meet the requirements to ensure the smooth progress of the subsequent rolling process.
3.Rolling.
The ingots are heated and rolled to make them a steel plate or strip with a certain thickness and width. In the rolling process, parameters such as temperature, rolling speed and deformation should be controlled to ensure that the mechanical properties and magnetic properties of the steel plate or strip meet the requirements.
4.Heat treatment.
Heat treatment of rolled steel plate or strip to optimize its mechanical and magnetic properties. The heat treatment process includes annealing, quenching, tempering, etc., which should be selected and adjusted according to the specific process requirements.
