Heat treatment, including quenching and tempering, is very important for casting balls quality. It influences a lot of in HRC, Wear rate & Price for Grinding media.

Hardening Furnace

/in

Continuous hardening furnace is the tunnel type; the length of the furnace is usually long. Workpieces go through the inside of the furnace with different temperature sections. Hardening furnace consists of heating element, heat resistant material, refractory bricks, furnace front door, and back door, lifting system, hydraulic system, tipper. Each section of the furnace has […]

Quenching process (quenching furnace)

/in

In materials science, quenching is the rapid cooling of a workpiece in water, oil, or air to obtain certain material properties. For oil quenching furnace, it contents the process of heating and quenching. For casting grinding balls, quenching process can be oil quenching for common high chrome balls, air quenching for super high chrome alloyed grinding balls; and for […]
