REFRACTORY COMPOSITIONS OF PLUG FOR TAP HOLE OF CONVERTER USING BY WASTE Mg-Cr BRICK

摘要

The present invention relates to a main raw material comprising a waste magcrod burned product, a pulverized product, and magnesia powder; A raw material and a binder including a scale powder as an additive; The present invention relates to a refractory composition for a plug for a turning furnace using a waste magcro refractory comprising 60 to 70% by weight of pulverized waste, 10 to 15% by weight of magnesia powder, 20 to 25% by weight of scale powder By weight based on 100 parts by weight of the starting material, and 5 to 8 parts by weight of a binder, based on 100 parts by weight of the starting material, It is usefully recycled waste magnocross-resistant bricks that are produced in large quantities after they have been used in RH facilities of STEEL factories, STS VOD ladles, lime firing furnaces, cement rotary kilns, etc. to reduce the cost of disposal or disposal, It is possible to provide a refractory composition capable of manufacturing a plug for a transformer box by recycling the waste microcrack. In addition, it is possible to efficiently use finite resources, and at the same time to reduce waste and reduce the cost of disposal.
