In order to comply with the cooling of pin parts, circulating water or compressed air mirror moving pool water can be introduced into the pool(180 grit aluminum oxide). When quenching with hanging rail, the crown block can swing back and forth for 10 ~ 15min(corundum sand). The requirements of the dispersion treatment are the same as those of the water quenching treatment, and the temperature rise curve is shown in the figure. 


The cooling time of the cake in water shall ensure that the casting is cooled below 200 ℃(180 grit aluminum oxide). Those who pour water into the inclined part are often cooled to below 60 ℃, while those who use hanging quenching are cooled for 20 ~ 30min, based on the principle that the casting surface is not hot after water is discharged(green silicon carbide). The temperature should not be too commercial to avoid overheating and grain growth.


When determining the test time, attention should be paid to the sharp changes of different materials in different wear stages under certain test conditions(180 grit aluminum oxide); Strengthening the test conditions and shortening the test time may change the failure state. Precipitation hardening treatment, suitable for dry high carbon austenitic manganese steel containing chromium, molybdenum, sail and titanium(240 grit aluminum oxide blast media). Clean up the defects and open the weld. 


This process method is feasible in theory, but it is difficult in practice(180 grit aluminum oxide). In addition to a small amount of good production conditions, it is difficult to adopt for factories with large number of escape injection boxes, different thickness of trim parts and large production scale without special measures(aluminium oxide sandblasting grit). As all engineering components that require high toughness, higher temperature solid solution and water cooling are used. 


According to the test(120 grit aluminum oxide), when the casting waste heat is 150 ℃, the hammer head treated by water solution and the hammer head quenched by conventional water at 1050 ℃ are bent and rotated for 1031h at the same time, and the drunk ore volume is 10951 tons, which is equivalent to the wear of the two(180 grit aluminum oxide). Arc gas wound is used to repair the uneven surface of riser cutting, technical joints of castings or surface defects(220 grit aluminum oxide blast media).


After the advent of water blasting and sand cleaning, it is envisaged to integrate water blasting and sand cleaning with water quenching treatment by using casting waste heat, so as to reduce labor intensity, prevent health, save energy and shorten production cycle(aluminum oxide abrasive powder). Matters needing attention when cutting austenitic manganese copper are as follows: as cast cutting(180 grit aluminum oxide). Generally, cutting is prohibited in the cold casting state.


The castings cooled by ring solution treatment shall be reheated or reheated into the furnace and maintained at 590 ~ 800 ℃ for 8 ~ 12h to fully analyze the fine and dispersed alloy carbides(aluminum oxide suppliers usa); Finally, heat to 870 ~ 1040 ℃ for 1 ~ 2H, conduct the second quenching and cool to below 200 ℃(180 grit aluminum oxide). 1050 ~ 1080 ℃ is commonly used(silicon carbide grit). 15 ~ 20 minutes before discharging, the furnace temperature rises to 1080 ~ 1100 ℃ again.


Finally, the melting temperature is closely related to the dispersion degree, morphology and quantity of carbides, and also affects the mechanical properties, especially the influence of anti poison orientation(180 grit aluminum oxide). The most important quality inspection work after this meltdown is the metallographic inspection of the furnace sample(aluminum oxide abrasive blasting grit). Calcium oxide in bauxite is difficult to be reduced by carbon and almost all of it enters the melt. 


At present, the proportion of fixed furnace and dumping furnace used in brown corundum production in China is about 3 ∶ 4(180 grit aluminum oxide). After the aging treatment and solution treatment, the aging treatment is carried out at a temperature of 800~400℃ to precipitate out the small alloy carbide spots and improve the initial hardness and wear resistance(white aluminum oxide 80 grit). Mechanical properties after water quenching, pearlization and re quenching.


In the painful material abrasion comparative test, the results obtained are shown in the table(garnet sand). The purpose of the dispersion treatment is to obtain a more uniform distribution of dispersed high-hardness balls and granular alloy carbides on the soft austenite matrix to increase impact wear resistance and improve wear resistance(180 grit aluminum oxide). Except for part of the spacer riser, most of the risers and press seams need to be cut.


The content of chromium oxide in sintered chromium steel brick is generally lower than that in fused cast chromium corundum brick(alumina sand). The existence of as-cast carbides promotes cracks on the cutting heating surface. Spraying means that the casting is not immersed in water(180 grit aluminum oxide). What is more serious is the superposition of casting stress and cutting thermal stress, which often leads to the danger of casting explosions. 


The oxygen-acetylene grid cutting system is usually used as the main method, and the arc gas is used as an auxiliary(steel grid). Carry out conventional heating and solid solution water quenching treatment first to eliminate coarse as-cast spheroids, uniform composition, and cool to below 550~600℃ during igniting; then carry out pearlitization treatment(180 grit aluminum oxide). Austenitic manganese steel pins are mostly cut after being dissolved in water(aluminum oxide blast media canada).


When the height of the casting (including the riser) exceeds the limit size allowed by the equipment, it cannot be heated in the furnace(aluminum oxide grit blasting). When part of the riser must be cut off in the cold state, the casting body should be immersed in cold water, leaving 30~ at the root of the riser(180 grit aluminum oxide). When the cutting is in progress, there is a special person to cooperate with the cutting and spray water to cool the heating surface. 


The main way to distinguish them is from the appearance(180 grit aluminum oxide). The repair of casting defects such as pores, pinch overflow, small cracks, etc., as well as the repair of grinding parts and the increase welding of the sweet sequence surface, all adopt arc welding. When cutting, the heat-affected zone should be minimized, and immersion (water cutting) cutting or spray (wood cutting) cutting should be used(glass bead blasting media suppliers). Benze post-cut system.


The raw materials used for refractory materials are artificially synthesized(46 grit aluminum oxide). The characteristics of the common process are as follows: when the casting is cooled to about 850~800℃ and the riser is cut in the red hot state, the disadvantages of cold cutting can be avoided, but the operation requirements are rapid, and the casting should be buried in the heat immediately after cutting(180 grit aluminum oxide). Slowly cool in sand or in a hot furnace(aluminium oxide abrasive grit).


immersion is the method of casting the body into the water, the cutting part is exposed to the water surface, and the auxiliary parts are all immersed in the water after the riser is cut(180 grit aluminum oxide). When cutting, it is required to be as fast as possible, in a short time, cut flat at one time, and repair the surface with little or no repair(aluminium oxide blast media). The rating standards adopted by various industrial departments and enterprises are different.


When we choose bauxite, we must choose high-quality bauxite products according to the specific situation and let them play their role(aluminum oxide abrasive media). Sintered products usually require inner lining, and the heat loss of unlined products accounts for 24% of the energy consumption of the product, and only 4% of the heat loss of the inner lining. 50mm margin, wait for the water to cut the second time(180 grit aluminum oxide). Corundum mullite is rarely found in nature.  


The process features are as follows(aluminium oxide sand): first round solution treatment, air cooling or water cooling after heating at 940 ~ 1080 ℃. Dipping is used for large riser castings, and spray cutting is used for small risers or gating systems(white aluminum oxide 180 grit). White corundum powder is suitable for the surface beautification of various high-end products, crafts or hardware(180 grit aluminum oxide). After sandblasting, the surface is white without any impurities, eliminating the trouble of cleaning. 


With the characteristics of good toughness and high strength, it is used as a component of various reaction vessels, pipelines and chemical pumps in chemical systems(180 grit aluminum oxide). The process flow of black corundum is as follows: corundum block - coarse crushing - medium crushing - crushing - segmented screen - magnetic separation - fine screen - Inspection - packaging(100 grit aluminum oxide). Utilization of silica in bauxite containing calcium. 


Bauxite refractory castable is an amorphous refractory material mixed with a certain proportion of refractory aggregate, refractory powder and refractory binder(aluminium oxide blasting). In the grinding of the consolidated brown corundum abrasive, the brown corundum abrasive is made into pellets and bonded to many points on the grinding disc, and the density distribution of the brown corundum abrasive is controllable(180 grit aluminum oxide). 


Due to the characteristics of the hydraulic dumping system itself, it has been developed in the field of corundum smelting(aluminum oxide 80 90 grit). This ensures the health and safety of the operator and improves the visibility of the operator(180 grit aluminum oxide). Great attention must be paid to the ratio of the molten mixture of titanium dioxide and aluminum oxide to keep it at a level that can produce brown corundum that meets the technical conditions(alumina grit).
