Taphole drilling machines

Taphole drilling machines

An effective operation of blast furnaces directly depends on an uninterrupted operation of its cast house equipment, including taphole drilling machines. DHM GROUP is one of the leading companies in the area of designing modern hydraulic taphole machines which meet the strict requirements for quality, reliability and automation of technological processes of blast furnace operations in the 21st Century.


  • DHM GROUP units are developed individually and can be placed in optimum positions in cast houses at both rebuilt and new blast furnaces.
  • Taphole drilling machines equipped with a specially developed hydraulic HPP-1200 puncher – the unit that our designers are very proud of – in combination with properly selected drilling tools form a smooth and even taphole line, regardless of the type of taphole mix.
  • Due to the wide range of technical parameters and boring settings, operators are able to choose optimum modes of machine operation.
  • Full automation of control processes, data filing, computer visualisation of the required parameters, remote controls and many other features comply with the requirements of even most demanding Customers.
