苏联马钢研究出并采用了一种模铸底板保护工艺,使用的是由耐火粉料、水玻璃、耐火粘土和石墨粉组成的耐火泥糊。用喷雾装置往底板上涂一耐火层。15个锭模的铸锭小车喷涂时间为3～5分钟,往底板中心和模壁下部涂厚5～20毫米的耐火保护层。涂后30分钟即可送去供铸锭用。锭模内注满钢水后,耐火泥糊中的水玻璃即分解,从而便于用压缩空气清理底板。
Soviet Union Masteel developed and applied a molded underlay protection process using a refractory paste made of refractory powder, water glass, refractory clay and graphite powder. Spray a fire-resistant layer on the floor with a spray device. 15 ingot casting mold car spraying time is 3 to 5 minutes, to the center of the bottom plate and mold wall thickness of 5 to 20 mm thick fire protection layer. After coating for 30 minutes can be sent for casting ingot. Ingot mold filled with molten steel, refractory mud in the water glass decomposition, so as to facilitate the use of compressed air to clean the floor.
