Safe use steps of tubular furnacelM8Muffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
1. Stir with water in the tubular furnacelM8Muffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
Castables are subcontracted. In addition to the main ingredients, there is a small bag of additives in each bag. Pour the main ingredients and additives into the mixer. Before using the forced mixer, the castables shall be dry mixed for about 1-2 minutes. The details of the tubular furnace and clean tap water shall be mixed. 77% + 1 kg of tap water shall be added to every 100 kg of castables. Water shall be added until the materials are evenly added while mixing. The materials can be discharged only after careful use. The mixed wet materials shall be timely transported to the construction site for pouring construction. If the wet material is stored for too long, resulting in poor construction performance, it shall be discarded. It is strictly prohibited to put the materials back into the mixer and mix them with water before use.
2. Mold castinglM8Muffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
The mold is firmly supported (without a large amount of slurry running) and brushed with oil or release agent (thin and uniform). After supporting the mold, the material is evenly distributed along the mold during cutting. When the material thickness is 200-400, the vibrating rod is opened in time. The vibrating rod can move in and out quickly, vibrate evenly, and prohibit long-time vibration at the same position to prevent particle segregation. When the surface of the material is submerged and the number of bubbles changes, it indicates that the material has been dumped. When the thickness of the casting body is greater than 400mm, the layered structure shall be continuous.lM8Muffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
3. Demoulding and maintenancelM8Muffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
After the castable has high strength (12-24 hours under normal temperature), the pouring formwork shall be removed. Before the strength is insufficient to withstand greater pressure, trampling, collision, etc. must be avoided. Otherwise, cracks and corner damage may occur. The maintenance time shall be appropriately extended or thermal insulation measures shall be taken (the optimal maintenance temperature can be guaranteed to be above 10 ° C). If the construction period is short, the ambient temperature shall be appropriately increased to accelerate the hardening of the casting. After removing the mold, the casting must be kept in a warm and humid environment for more than 12-24 hours before baking.
