Preparation method of light refractory brick
The invention discloses a preparation method of a light refractory brick, and belongs to the technical field of refractory materials. According to the invention, pig bones with certain fineness are subjected to hot pressing to reduce density of the refractory brick; a small amount of calcium bicarbonate is added, carbon dioxide gas is generated under the action of heat, the refractory brick can obtain rich pore structures, flowing and diffusion of melts under the action of high temperature are facilitated, a good mechanical effect can be achieved on the surfaces of the pore structures, and themechanical performance of the refractory brick can be guaranteed while the porosity of the product is guaranteed. According to the present invention, minerals are sequentially subjected to ball milling, grinding, heating and cooling to improve the internal porosity degree, and internal components are subjected to thermal polymerization at the high temperature to form new components, so that the mechanical strength of the refractory brick is improved, pig bone powder is subjected to hot pressing treatment, and the density of the formed brick material is reduced through the permeation modification of a functional reagent. The preparation method solves the problems of poor mechanical properties and high density of the common refractory brick at present.
本发明公开了一种轻质耐火砖的制备方法，属于耐火材料技术领域。本发明对一定细度的猪骨进行热压作用，降低本耐火砖的密度，添加的少量碳酸氢钙，热作用下产生二氧化碳气体，有利于本耐火砖获得丰富的孔隙结构，有利于高温作用下熔融物的流动和扩散，并能够于孔隙结构表面良好的机械作用，在保障产品孔隙率的同时，能够保障本耐火砖的机械性能。本发明采用对矿物进行有序球磨、研磨，升温降温改善内部孔隙程度，并在高温下使得内部组分热聚形成新的成分，提升本耐火砖的机械强度，对猪骨粉进行热压处理，通过功能性试剂的渗透改性，降低构成砖材的密度。本发明解决了目前常用耐火砖的机械性能不佳，密度较大的问题。
