High chromium alloy casting ball is also called high chrome ball.High chromium alloy cast balls are widely used in cement, building materials, metal mining, coal slurry thermal power, chemical engineering, ceramic coating, light industry, papermaking, ultrafine powder preparation of magnetic materials and other industries and further processing.

Anhui phoenix form the production of high chromium alloy cast balls

Using iron mould coated sand production line production, to ensure the stability of product performance;

By using constant temperature pouring casting, avoid molten iron in the process of casting products internal quality defects due to temperature difference is too large;

Low leakage type casting, ensure high chromium alloy cast balls inside without sand inclusion;

The sprue gate positioned filter, further control slag;

With double row push-rod continuous quenching line, quenched and tempered change sphere internal organizational structure, reduce the sphere stress;

The special quenching oil was configuration, further enhance the performance of the high chromium alloy casting ball after quenching.

 

Specialized in the production of advanced technical achievements in anhui phoenix form high chromium alloy cast balls of high hardness, high wear resistance, high toughness, low breakage rate technique index is well ahead of other high chromium alloy cast balls of the same kind of enterprise production, decrease the user with the ball, at the same time, low broken rate more protection inside the mill lining board, prolong the service life of mill liners, greatly reduce the production cost of enterprises.
