Six decades of basic refractories — from a pioneering Konya plant to a 40-country exporter.
KONREF began in 1966 with the involvement of Japan's Marubeni Corporation — a heritage of technology and partnership that still informs our standards today. We were the first company in Türkiye and the Middle East to make basic, magnesite-based refractories in a fully integrated way.
Decades of investment in mining, the rotary kiln, modern laboratories and computerised production lines have made KONREF the country's largest refractory producer.
The Konya plant was inaugurated in 1966 under Sümerbank — the state industrial bank that seeded much of Türkiye's heavy industry — with technology and partnership from Japan's Marubeni Corporation.
It was the first integrated basic, magnesite-based refractory works in Türkiye and the Middle East — the foundation on which KONREF grew into the country's largest refractory producer.
Konya Selçuklu Krom Magnezit Tuğla Sanayii A.Ş. is established — with the involvement of Marubeni Corporation (Japan) — as Turkey's and the Middle East's first integrated basic, magnesite-based refractory plant.
KONREF earns the TS-EN ISO 9001 quality certificate, held continuously ever since.
New investments and a modernized laboratory expand the product range by roughly 90%, covering virtually every basic-refractory need across industries.
The largest refractory producer in Türkiye, exporting to 40+ countries and part of Özkaymak Holding.
