What are the characteristics of furnace bottom grouting technology?
Answer: The blast furnace is one of the important equipment in the metallurgy process, which has the advantages of large output, high production efficiency and low cost. Its structure is divided into parts such as furnace throat, furnace body, furnace waist, furnace bosh, furnace hearth and furnace bottom, among which the furnace bottom is a cylinder, and the foundation of the furnace bottom is made of continuous pouring of concrete, which is the stable core of the entire blast furnace. In the process of new construction, renovation or overhaul, it is often encountered that there are gaps or leaky areas at the bottom of the furnace that need to be filled and reinforced , nano-scale micropowder, functional admixture and other materials have been strictly formulated and pre-mixed evenly. When using it, you only need to add tap water in proportion and stir evenly. It can be continuously pressed in by specific mechanical equipment. The normal temperature molding strength of the material High, compressive strength 1d>20MPa, 28>60MPa, initial fluidity 2300mm, construction operation time 22h, the material has self-compacting properties, high bonding strength, compact without hollowing after grouting, new and old foundations do not peel off, the whole Good performance, heat resistance temperature 3500°C. The ball valve switch is reserved for the grouting hole, which is used for grouting flow control and sealing. Stir the RG-X evenly according to the technical requirements, and then put it into the hopper for standby. Inhale the material through a grouting equipment with a certain power, open the reserved grouting holes one by one, wait for the grout to overflow from the observation hole, immediately close it and start the grouting of the next grouting hole, and this process cycle continues until the entire bottom of the furnace is completed. Lianrongda furnace bottom grouting technology is efficient and convenient in construction, and the pressing speed can reach 3t/h~5t/h. After verification of a large number of furnace bottom grouting projects, Lianrongda furnace bottom grouting technology is convenient, high-quality, high-quality Efficiently solve customers’ problems, RG-X has excellent material performance, and the completed projects are in normal operation
