Condensation is one of the pivotal parts of a turbine generator set. A condenser converts a gas or vapor into a liquid and quickly transfers heat out of the tube. Its performance directly affects the operation of the unit. Condenser works in a high-temperature environment which is essentially an exothermic process. As the main heat…
Most of the hydraulic cylinder is composed of a cylinder, cylinder head, piston and piston rod and sealing device. The comprehensive performance of the cylinder such as pressure resistance, wear-resistance and fatigue strength, determines the service life of the hydraulic cylinder. The cylinder is usually required to withstand pressure within 20Mpa (continuous pressure), and the…
There are some necessary processes such as hot rolling, cold rolling, cold drawing, cold drawing in the steel processing. Hot rolling, as opposed to cold rolling, is rolled above the recrystallization temperature. Hot rolling can destroy the casting structure of ingot, refine the grain of the steel, eliminate the microstructure defects and improve the mechanical…
We introduced the method of nitriding steel in the last article. As we know, nitriding treatment refers to the chemical heat treatment process in which nitrogen atoms penetrate into the surface of the workpiece under a certain temperature and medium to increase the wear resistance, surface hardness, fatigue limit and corrosion resistance of steel parts.…
It is understood that the invention of stainless steel soap is accidentally discovered by steel engineers, their hands stained with the smell of heavy oil in the stainless steel alloy parts grip together, which can effectively remove the smell of the hand. Tests have shown that several stainless steel soaps rated “good” when scrubbed in…
Nitriding is a chemical heat treatment process in which nitrogen atoms penetrate into the surface of the workpiece at a certain temperature and medium. Common methods are liquid nitriding, gas nitriding, ion nitriding, the latter two types are the most commonly used. The traditional gas nitriding is to put the workpiece in a sealed container…
