Saving straight graphite crucible size, energy straight graphite crucible long manufacturers recommend straight barrel furnace crucible size, isostatic straight barrel furnace crucible size, straight barrel furnace IF crucible factory First, I plant the introduction of the most advanced isostatic crucible molding equipment and technology to advanced fire-resistant materials, the use of high-tech formula to develop a new generation of high-quality silicon carbide crucible furnace, this product has: a large volume density, high temperature, heat and fast, acid erosion, high temperature strength, oxidation resistance characteristics. Straight saving size graphite crucible, graphite crucible saving straight long service life is 5-10 times the manufacturers of clay graphite crucible. The products are widely used in various non-ferrous metal smelting and casting, stable quality, long life, a significant reduction in fuel consumption, reduce labor intensity and improve work efficiency, and create a better economic benefits. Our research team of 11 people, there are technical guidance tracking service for many years 15,830,602,532 willing to work together to communicate with the public, and seek common development. Straight barrel crucible furnace size, straight barrel IF crucible furnace crucible factory a routine operation Caution 1. Inspection: Be sure to test before using the crucible to prevent any possible damage, ensure the integrity of the crucible. Be sure to always check the use of the crucible, comprising: a crucible wall of wear, damage, ensure that the crucible is not sick job. 2. Install: A, pre-installation check coil mud packing is in good condition, nearly circular shape, if necessary, repaired and thoroughly dried. B, close to the coil layer of mud packed house smooth surface media, such as mica or glass cloth, and to ensure that overlays the same direction. C, install ground fault protection and arrangement of the ground. D, at the bottom of the furnace was added 3 to 4 inches of litter and gently ramming, remove each for gas and before the next layer of screed ramming litter. 3. Direct barrel crucible furnace size, straight barrel IF crucible furnace manufacturers, chipped: generating remove metal splashes, avoid the use of topical overheating and damage the coils. 4. Note: A, on the center of the coil may produce hot spots and cracks. B, not less than the minimum bottom of the crucible coil. C, check the crucible height and level must be adjusted if necessary. D, with wedge fixing the crucible in an electric furnace coil center. E, between the crucible and the furnace wall vibration backing Dry powder, (must be non-sintered) having a thickness of one-tenth of the diameter of the crucible. F, pound hit from the top of the crucible is about 50 ~ 75MM, it should be sealed using plastic top of the crucible and the production of the ventilation holes in the plastic can help dry. Second, the crucible 1. Use of a straight barrel furnace crucible size, straight barrel furnace IF crucible manufacturer, the crucible preheating A, crucible preheating is extended one aspect of the crucible life, in many cases, the crucible is damaged during preheating , which damaged before the molten metal is not obvious. B, when the time within the furnace refractories conservation, Do not heat the crucible, or a change in temperature will cause the adhesive oxidation. C, the crucible of the crucible is heated first, every 10 minutes, an increase of 20% power until the optimal operating power. 2. The feed crucible A, the crucible furnace straight barrel size, straight barrel intermediate frequency crucible furnace manufacturers, the bulk metal ingot vertical to join the crucible, to ensure adequate clearance between the ingot and the crucible wall. B, not to the level of the cold ingot wedged crucible because during heating, expansion of the metal can cause fracture of the crucible. C, then under no circumstances be thrown into the crucible ingot, as this will damage the edges and the crucible wall. Ingots or other heavy metal block should use special pliers carefully placed in a crucible. D, and chunks of scrap metal ingots must be added before drying, the metal material should be placed loose bottom of the crucible, the best first pieces expected to join the crucible bottom, to a large metal ingot bedding. E, crucible leave some liquid metal, can accelerate melting metal material, avoid large pieces of metal ingots were added to a small amount of liquid metal, which will cause chilling or solidification, contributed to the crucible immediately broken. F, when the furnace outage, the crucible must be completely emptied. Otherwise, due to the different expansion will cause the metal solidifies in the crucible, in the next heat, leading to rupture of the crucible. G, if added to the liquid metal, to avoid catching too full. Be sure to pay attention to not throw ingot crucible, because the sharp edges of the metal ingot can damage the crucible wall. 2. Cleaner, degassing and refining A, an additive effect for the molten metal 1, energy straight size graphite crucible, graphite crucible saving straight long factory, straight barrel IF crucible furnace manufacturers produce protective covering to prevent oxidation. 2, helps remove gas and solid impurities. 3, adjusting the alloy chemical composition, improve casting performance and basic organization. Straight saving graphite crucible size, saving manufacturers long straight graphite crucible 4, to ensure slag soft, fluffy, not hard, sticky. B, slag refining method, according to the manufacturer's instructions, the use of additives. Add only the minimum amount required to complete the slag. In order to extend the life of the crucible, the only refining agent is added prior to casting, straight barrel crucible furnace size should be at least one-third of the capacity of the molten metal in the crucible straight barrel IF furnace manufacturers crucible. 2, when the end of the day, you should clean Crucible, remove sticky residue. Because unused slag agent will penetrate slag, diffuse into the crucible, increasing the risk of erosion of refining agent. 3, the speed of the crucible refining agent is reacted with proportional to the temperature of the crucible overheating will seriously shorten life. 4, good mobility refining agent will pass through the crucible wall, oxygen and combustion gas attack crucible, the bubble glazed and larger pit from the outside is a symbol of this encroachment. 5, outside the crucible of the refining agent spillage or splashes produce the same consequences. C, a casting method, when the molten metal reaches the desired casting temperature, and according to the requirements of the degassing and deslagging, it should be cast as soon as possible. 2, is not recommended for the molten metal in the crucible prolonged heat, which shortens the crucible of life and reduce the metallurgical quality. 3, let the crucible in the casting position and continue to heat, is not operating. This can lead to breathing, metal burning, crucible wall corrosion uneven wear prematurely. 4, when pouring a small amount of metal from the large tilting crucible furnace, the next time between pouring crucible should be restored to the vertical position. 5. Special Note: When the crucible filled with molten metal, the crucible handling equipment must be firm and has been an appropriate crucible bottom support crucible. 3, straight barrel crucible furnace size, straight barrel IF crucible furnace manufacturers, slag formation A, slag produced in the molten metal bath, in order to eliminate contaminants in the liquid metal, oxides and inclusions, refining process, partially fused slag adhering to the walls of the crucible. B, when the newly formed slag is quite soft and easily removed. When the slag retained, they become extremely hard and difficult to remove. C, the crucible wall layers of slag will curb the crucible of performance, energy-saving straight graphite crucible size, energy straight graphite crucible long factory, straight barrel furnace crucible size, straight barrel furnace IF crucible manufacturers, but is the crucible in advance damaged most One of the common reasons. 4, the cleaning method A, the proper slag removal is important. B, after the first heat, when the crucible is hot, it should be thoroughly scraped slag. C, and then, when the end of the day, clean the crucible.
