弥散型透气砖采用高纯原料，经高温烧成制得。该型透气砖通过弥散贯通气孔供给氩气，具有热态强度高，抗热震、等优点，其性能通气率100%，无需氧洗维护，满足和适应特殊精品钢冶炼，对洁净钢生产有较大的优势。

The porous plug is made of high purity raw material and fired at high temperature. This type plug supplies argon through the diffusion through the porosity, has the advantages of high hot strength, thermal shock resistance, etc., its performance ventilation rate of 100%, no oxygen washing maintenance, to meet and adapt to special fine steel smelting,clean steel production has a greater advantage.
