Inconel 718 Spring Production Process Diagram
Raw materials and control
Jinchuan Nickel, Niobium Bar, Molybdenum Metal, Baosteel Industrial Pure Iron Only use the best quality Jinchuan nickel and Baosteel industrial pure iron, with a nickel purity of up to 99.99% and industrial pure iron purity of up to 99.8%, to control the impurity content of materials from the source
Process Control
The entire process control is carried out from raw materials, material melting, forging, wire drawing, spring winding, finished product inspection and warehousing, and after-sales quality tracking and resolution. Quality control runs through the entire process of product design, material synthesis, spring forming, and overall operation.
Dual process --VIM+ESR:
·VIM is a method of melting furnace materials by using electromagnetic induction to generate eddy currents in metal conductors under vacuum conditions
·ESR is a method of melting using the resistance heat generated by the current passing through the slag as a heat source.
·The dual process used by OBT can control the chemical composition of the Invar smelting process to the greatest extent possible. Through processes such as electromagnetic stirring under vacuum environment, high-temperature smelting, chemical refining, and condensation crystallization, high purity, extremely low impurities, dense and uniform metallographic structure and chemical composition of the Invar alloy are produced, which has excellent physical and chemical properties.
Quality Control:
During the material melting process, OBT conducts five quality inspections, including two vacuum melting and three electroslag remelting. Strict process monitoring is carried out on the samples obtained from smelting using a spectrometer and chemical detection to ensure that the chemical composition and metallographic structure of the final steel ingot meet the highest quality requirements of the Invir alloy in the United States.
