冷捣糊
冷捣糊，也叫粗细缝糊，是以高温煅烧无烟煤，石墨粉，冶金焦为主要原料，以添加煤沥青，煤焦油为粘结剂制成的低温粗细缝糊，用作炉底炭捣打层，填充炭块与炭块之间的缝隙炭素糊料产品。
Cold ramming paste, also known as thick and thin seam paste, is made of calcining anthracite, graphite powder and metallurgical coke at high temperature as the main raw materials, with the addition of coal pitch and coal tar as the binder, used as the bottom of the furnace coal ramming layer, filling the gap between the carbon block products.
