Brazing
Introduction
Brazing is a process of joining two objects by using a third, weaker material that remains solid at the joining temperature. The most common brazing procedure is torch-based brazing. This process uses heat to melt the filler metal, which is held in place by capillary action to join t......

vacuum furnace
Vacuum ovens are incredibly useful pieces of industrial equipment, capable of drying and degassing items that regular ovens cannot handle. A vacuum oven works by eliminating the presence of any air or moisture in the oven chamber, controlling temperature and airflow to varying degrees. Many indust......
Roll eddy current detection device and its adjustment method
Roller Vortex Flow Detection Device and Its Calibration Method
The pressure fluctuations of the working gas were analyzed by means of fast Fourier transformation, combined with vortex motion in the roll passes, and a device for online monitoring of vortex flow of rollers on the rolling mill was d......
Eddy current inspection
Introduction
Eddy current testing is a form of non-destructive testing used to detect surface and subsurface flaws or irregularities in metallic materials and electrically conductive non-metallic materials. Eddy current testing is used across many industries including aerospace, automotive, milit......
Form rolling
Cold rolling is a steel forming process in which a metal bar is passed through a pair of rolls to reduce the thickness, increase the yield strength and increase the hardness of the metal bar. This type of metal forming process involves passing the metal bar between two rolls that rotate in opposit......
Induction heating heat treatment
Inductive heating is a non-contact heating process used to heat ferromagnetic materials such as steel and iron. In this process, an alternating current flowing through a coil creates an oscillating magnetic field, which induces eddy currents in the material being heated. This phenomenon, known as ......

Induction Cooktops
Induction cooking has been around for a long time, but with today’s modern amenities and advanced technology, induction cooktops are becoming increasingly popular. Induction cooktops are a type of stovetop or cooktop that uses induction technology to heat cookware to extreme t......
Research on Reducing Sulfur in Hot Metal
Research on Reduction of Sulphur in Iron Melt
Abstract
Sulphur is a harmful and unwanted impurity in iron melt, and its control is a long-term task for ironmaking industry. In this paper, the reduction methods for different types of sulphur sources in iron melt are discussed. According to the di......
Spring steel (GB 1222-64) (1)
Spring Steel (GB 1222-64) (1) Introduction Spring steel is a special type of steel that is used in the production of springs and other related products. It is a high carbon steel with a tensile strength range of between 35 to 75 kg/mm². The main chemical elements that make up spring steel are mang......
