After the coke oven structure is constructed and installed to the point where it is ready for ignition and heating, it enters the preparatory phase prior to commencing operation. To ensure the normal functioning of the coke oven after it goes into operation, it will operate in a hot state based on the heating temperature specified for it. The tasks involved in hot-state operation generally include: 1. Sealing the joints and applying plaster to the regenerator walls of Coke Oven No. 1. Once the furnace temperature reaches 300 degrees Celsius, the joints in the regenerator walls are sealed and plastered. Before grouting or plastering, clean the walls of the heat storage chamber thoroughly. Fill any cracked joints with a mixture of asbestos rope and clay, fireclay, or glass cement, then seal them properly, and apply grout made from clay and fireclay. Plastering is carried out in two stages. During the first application, the surface should be compacted firmly, but it need not be made completely smooth; once the first layer has dried and hardened, the second layer is applied. This second layer also needs to be compacted and smoothed to achieve an attractive appearance. The plaster thickness is 20 millimeters. 2: Plastering of the exhaust gas valve – Plastering is carried out once the furnace temperature reaches 300 degrees Celsius. Plastering is carried out in three stages; the key point for the first application of plaster is to apply it carefully ； Compact the surface a second time; do not make it too smooth. Apply the third layer only after the second layer has dried and hardened ； The third layer needs to be compacted and smoothed out to ensure it looks good. The plastering thickness is 30 millimeters. 3: Vertical transportation equipment needs to be set up and taken down, mortar mixers need to be installed and removed, and temporary scaffolding used during the heating process must be taken down. Vertical transportation equipment is required to lift materials for hot-process operations, while mortar mixers are used to prepare mortar and grouting materials; temporary scaffolding is needed for furnace heating and must be removed as well. These tasks must be carried out during the furnace heating period or before production begins. The setup and removal of vertical transportation equipment and scaffolding must be done in strict accordance with construction standards and requirements, and no illegal operations are permitted. 4: Removal of the heating stove. The removal of the heating stove is carried out when the temperature of the stove reaches around 500 degrees Celsius. When removing the stove, pay attention to personal safety; be careful not to get burned by the hot refractory bricks. Do not discard the debris resulting from the removal carelessly, and strictly follow the operating procedures when removing the stove, stacking the removed materials neatly. 5: Grouting of the protective plate – Once the furnace temperature reaches 700 degrees Celsius, grouting of the protective plate is carried out. The protective plate must be filled in four stages, with each filling process waiting until no bubbles appear before proceeding to the next one. For the last time, level it out and smooth it. 6: Construction of the small burner – Once the temperature inside the furnace reaches 750 degrees Celsius, the construction of the small burner can proceed. When building this burner, it is necessary to ensure that the mortar is sufficient, that the joints between bricks are straight, and that the outer surface of the brick structure meets the specified standards for flatness. 7: Blow and clean the strip groove, grout the strip groove; blow and clean the furnace top, grout the furnace top. For blowing and cleaning, proper ventilation is required to ensure thorough cleaning. Grouting should be carried out in multiple stages, continuing until no more mortar can be poured in. 8: Construction of the resistance wall top, construction of the resistance wall sides, and finishing of the furnace top. When building the resistance wall, it is necessary to ensure that the mortar is sufficient, the joints are straight, and the surface of the brick structure meets the specified requirements for flatness. The scaffolding used must be safe, with no protruding parts. 9: Grouting of brick gas channels – The grouting of brick gas channels must be carried out at the bottom of the furnace; the client provides the equipment, and the grouting is done before the coal gas is sent back into the furnace. 10: Sealing of the riser base is carried out after the installation team seals the riser base with asbestos rope; phosphate clay mortar is used for this sealing. Make sure the base does not smoke. 11: Remove the temporary partition wall (which serves as the furnace door during gas heating), remove the temporary fire bed, place the plug bricks, and grout the grinding plates. When removing the temporary partition wall, removing the temporary fire bed, placing the plug bricks, and grouting the grinding plates, it is necessary to wear protective clothing, masks, and gloves. Operations must be carried out strictly in accordance with the prescribed procedures, and workers must be properly dressed to prevent burns and scalds.
