Production method of refractory mud blank

Abstract

The invention belongs to the technical field of refractory raw material production, in particular relates to a production method of a refractory mud blank. When the refractory mud blank is produced, lignocellulose is added into the raw material. In the invention, the lignocellulose is used as a refractory mud blank additive so as to ensure that the refractory mud blank is not pulverized and cracked in the process of drying, and is not burst and chipped in the process of sintering, thereby ensuring that the sintering is even, and the operation of a kiln car is safe.

Description

technical field [0001] The invention belongs to the technical field of production of refractory raw materials, in particular to a production method of refractory mud. Background technique [0002] Usually the process of producing refractory raw materials by wet method is: ore crushing→wet grinding→filtering mud→squeezing mud into billets→drying→sintering. Since the refractory mud billet is a cuboid and normally contains 8-17% water, the temperature of its upper, lower, left, right, and inner surfaces and interiors is not uniform when it is dry, and it is easy to be inconsistent when dehydrated, so it is very easy to crack. At the same time, since the materials in the mud billet are all composed of fine powder (about 200-500 mesh), the strength decreases after dehydration, and it is very easy to appear pulverization, so that the pulverization rate of the refractory mud billet is relatively high (15-35 %). Moreover, when the refractory mud is dried and fired, since the mud m...
