ABSTRACT:
A process for producing unburned basic refractories wherein a binder is added and kneaded with a basic refractory material and the kneaded mixture is press-formed. The binder is a thermoplastic resinous material which is obtained by removing a light fraction having a boiling point of less than 200.degree. C under a reduced pressure of 100 mmHg and having a benzene-insoluble fraction content of less than 10% by weight from at least one member selected from the group consisting of a heavy oil obtained by a steam cracking of petroleum and a polymerization product of said heavy oil. The slag penetration resistance, slag erosion resistance and slaking resistance of the given unburned basic refractories are substantially improved.
