Quenching And Tempering For Cast Grinding Balls

 

What is grinding ball heat treatment

After grinding balls are manufactured in casting ball metal mold or automatic grinding ball molding line, the next most important process is heat treatment. Grinding ball heat treatment includes quenching and tempering. Grinding ball heat treatment is used to quenching and tempering for casting balls.


Why grinding ball need to heat treatment furnace

For casting steel ball, the most important is the balls quality. According to the casting production technology, most users are using two ways to control grinding balls quality. First, they must control well the chemical composition, this step is very easy to come true. Second, the most important is by heat treatment furnace.

The main purpose of grinding ball heat treatment furnace is to improve grinding balls quality, change its internal performance and improve its harness.

Quenching process is cooling grinding balls at a rapid rate from a predetermined high temperature. This process is important as it is key in addressing the main challenge of manufacturing steel balls of high quality. Tempering process is done to relieve the metal of any residual stresses that might be sent up during the quenching process of grinding balls.




How Does Cast Grinding Ball Works

Grinding ball heat treatment furnace is driven by hydraulic and the running is stable and reliable .It is mainly made of by heating furnace body, quenching system, loading balls basket turning machine, pushing machine, turning machine, hydraulic system and electric control system. It automatically heat treatment of grinding balls and change grinding balls' metallographic structure to improve the hardness the whole quality of grinding balls by fiber cotton, PLC, intelligent temperature controller, other detection devices and heated by resistance components.

WHAT DOES VALVE TECHNOLOGY MEAN TO YOU?

One of the components of an engine is the valve. Engine valves are mechanical components that support internal combustion. One approach is the consumption of compressed air. Based on experiences from valve manufacturer (Desu Automatic Manufacturer. Co.,Ltd), around 500 butterfly, 1,000 seat and 1,500 double seat valves are installed in your average large dairy (700 million kg raw materials p.a.). If compressed air consumption could be reduced by just a few percent, this could result in considerable savings. Another way to increase efficiency is to minimize cleaning fluid losses. An NW 65 valve with 2.5 bar line pressure can easily lose almost 2 liters of fluid per second. This loss occurs due to the necessary leakage space in double seat valves, which is cleaned when the valve disc is raised. To prevent the loss of too much cleaning fluid, the response times of the valves must be as short as possible – solutions can be found in their design.   Related products: API 6A Gate Valves...
