1. Induction Heating Surface quenching definition: is the use of a certain method to produce a certain frequency of induction current on the surface of the workpiece, the surface of the parts quickly heated, and then quickly quenching cooling heat treatment operation. PRINCIPLE: As shown in the figure, electromagnetic induction produces an induced current of […]
There are many different kinds of grinding media used in ball mills, such as forged grinding media and cast grinding media. Among them, forged grinding media are called forging balls for short; cast grinding media are called casting balls for short; cast grinding media are divided into high, medium, and low chrome. Today, the main […]
In the heat treatment process, the reject rate caused by the quenching process is usually higher. This is mainly in the quenching process, and at the same time, the formation of greater thermal stress and structural stress, in addition, it is easy to be exposed in the quenching and tempering process because of the inherent […]
1. Take a pinch. 2. Exhaust. 3.Slag collection. 4.Logo for the metal filling cavity. Casting riser is a part designed to supply the shrinkage of casting during solidification to prevent shrinkage cavity and shrinkage porosity.
High Chrome cast iron containing 12.30% chrome and 2.4-3.6% carbon can be highly alloyed and heat treated to obtain martensite or austenite or mixed matrix and special carbides of chrome. This particular carbide is a hexagonal system of Me7C3 with hardness as high as HVL200. 1600, much higher than the cementite type of carbides and common mineral […]
