Special Method

Many customers make requests asking for special holes to be created in already installed refractories, for purposes like installing anchors to the refractories or draining out glass. Making such holes in the refractories installed in equipments in operation is therefore one of the services we offer.


Drilling by MAP


Drilling with a core drill

Micro Arc Processing (MAP) allows quick drilling in the refractories using arc welding. Regardless of refractory material, MAP can be applied to both general bonded and electro-cast refractories.

A core drill is mainly used for drilling a hole for draining glass from glass melting furnaces.Since such drilling could cause unexpected leakage from the hole during drilling, drilling is performed only by our highly experienced experts with specialized knowledge.
