PLASTIC REFRACTORY MATERIAL Russian patent published in 2006 - IPC C04B35/66 C04B35/00 

FIELD: iron and steel industry; production of plastic refractory materials.

SUBSTANCE: the invention is pertaining to production of the plastic refractory material, which is intended for usage in the iron and steel industry, in particular, in foundry for tightening and sealing of the metal-casting equipment. The plastic refractory material contains (in mass %): the refractory filler with the inorganic binding - 50.0 - 95.0 (at the ratio of the refractory filler - 85.0 - 95.0 and the inorganic binding - 15.0 - 5.0); the elastomer in the form of caoutchouc - 3.5 - 21.0; the carbon-containing material in the form of bitumen - 0.50 - 15.0; the plasticizer in the form of the industrial oil - 0.5 - 10.0; the adhesive agent in the form of graphite - 0.5 - 4.0. The refractory filler is presented by corundum, periclase, silicon or their mixtures. The inorganic binding represents a low-melting mixture of oxides. The technical result of the stated invention is production of the composition of the plastic refractory material- with the increased slag-resistance, non-toxic, vibrations-resistant, keeping leakproofness for the whole period of operation and easily removable at dismantling the connectors and joints of the metal-casting equipment.

EFFECT: the invention ensures production of the plastic refractory material composition of increased slag-resistance, non-toxic, vibrations-resistant, saving the tightness for the whole service life, easily removable at dismantling of the metal-casting equipment connectors and joints.
