一般电阻炉内支承电阻丝的耐火砖常采用标准搁砖(又称桥形砖、小脚砖等),如图1所示。这种砖其T字形槽内安装铁丝钩(钩住电阻丝),通常容易损坏,并影响电阻丝的使用寿命。为延长电阻炉的使用期和砌筑搁砖、装拆电阻丝的方便.我们改革了电阻炉搁砖的几何形状,见图2、图3。经儿年的生产实践,证明改形搁砖比原标准 Ordinary resistance furnace support resistance wire refractory brick commonly used standard brick (also known as bridge brick, foot brick, etc.), as shown in Figure 1. The brick installed in the T-shaped groove wire hook (hook resistance wire), usually easy to damage, and affect the life of the resistance wire. In order to extend the service life of the resistance furnace and brick laying masonry, assembly and disassembly of resistance wire .We have reshaped the geometry of the resistance furnace brick, see Figure 2, Figure 3. After years of production practice, proof remodeling brick than the original standard
