近来人们成功开发了1种催化活化树脂作为含碳耐火材料的结合剂。与普通树脂相比,这种结合剂系统碳化所形成的炭为石墨结构,在室温下采用简单的3点弯曲法测定的这种结合系统结合镁碳材料的载荷与位移曲线发现,这种镁碳材料具有更高的弹性和杨氏摸量,有利于减弱其使用过程中因热冲击而形成的热应力;文中还介绍了采用普通树脂和催化活化树脂结合镁碳砖在转炉、钢包上的使用情况。
Recently, people have successfully developed a catalytic activation of the resin as a carbonaceous refractory binder. Compared with ordinary resins, the carbon formed by the carbonization of the binder system is a graphite structure. The load and displacement curves of the bonding system combined with the magnesium carbon material measured at room temperature using a simple 3-point bending method show that the magnesium The carbon material has higher elasticity and Young’s modulus, which helps to reduce the thermal stress caused by thermal shock during its use. The paper also introduces the use of common resin and catalyzed activated resin combined with magnesia-carbon brick in converter and ladle Usage.
