He holds 2 patents that showcase his innovative approach to improving processes in the iron foundry industry. His work has significantly impacted the efficiency and effectiveness of metallurgical operations.

Latest Patents

One of J Colling's latest patents is the "Oxygen Lance," which is designed for blowing oxygen from above into a ladle of an iron foundry. This lance features a nozzle head with at least four main tuyeres of larger diameter and several ancillary tuyeres of smaller diameter. The larger tuyeres are intended for decarburizing the metal, while the smaller ones facilitate afterburning of carbon monoxide just above the melt surface. The axes of the main tuyeres are inclined at an angle of about 14 to 17 degrees, while the ancillary tuyeres are inclined at an angle exceeding that of the main tuyeres by about 30 to 50 degrees. To regulate the airflow through the ancillary tuyeres, they are equipped with inner peripheral inlays or grooves of annular or helicoidal shape.

Another significant patent is the "Refractory Piece Permeable to Gases." This invention is designed to be incorporated into the inner refractory lining of a metallurgical container, ensuring that one surface is in contact with the molten metal bath. The opposite surface is equipped with means for introducing gas under pressure. The piece is generally hexahedral and consists of a mass of nonporous refractory material with local discontinuities extending throughout its height. This design allows for the desired amounts of gas to be blown into the metal bath while maintaining the longevity of the refractory lining.
