There are two sets of smelting methods：

The first set, medium frequency furnace smelting, with lower cost and acceptable steel quality,

The second set, Ultra High Purity Smelting Method by EAF+LF+VD furnaces,

Combining our special heat treatment process, DHT alloy hammers (with different hardness hammers) developed for harsh working conditions have greatly increased output (service life) and saved a lot of operating costs, including but not limited to:

Labor operation cost, downtime cost, cost of wear-resistant parts quantity, etc

Highly praised by our customer's maintenance engineer.
