- Q:In addition to diamonds, Hunan there are no good carbide manufacturers? Product advantages in the ordinary blade, knife head and mining tools. Which factory's alloy is of good quality? The best size, with the original tungsten powder. Please know what to say, first thank you
- Looking for packing box manufacturers can find the letter plastic
- Q:What kind of material is the alloy drill bit?
- Alloy bit generally refers to the hard alloy bit, divided into integral, welded, indexable inserts and replaceable type.The main components of cemented carbide are tungsten carbide, cobalt, etc., the hardness is relatively high, generally above HRC90 degrees, and it is suitable for batch processing and hard processing!
- Q:General carbide and high-speed steel blade cutting speed? (about the range is OK.)
- Carbide cutting tools, cutting speed limit is 100 meters / minute, usually 50-70 meters per minute;High speed steel cutting tool cutting line speed limit is 10 meters / minute, commonly used 5-8 meters / min..
- Q:After welding, and then sharpening, grinding into 4 Pyramid shape, and then used to knock stone, which is not easy to bad, which is more durable? Model number is D224, I would like to ask you, which should I buy? I'm mainly used for knocking stones.
- YG8C is used on impact drills, which is suitable?
- Q:What alloy tool can be used as hard alloy?
- At present, the world's best tool materials used for cutting high alloy steel is CBN, CBN is the world's second hard materialsThe hard material is diamond, but the chemical composition of diamond are carbon, in high temperature processing conditions, the carbon will react with iron, so the processing of diamond is not suitable for high alloy steels
- Q:Several hard alloy cutter lathe with?
- 2 kinds! They are clamp type and welding type.
- Q:Can hard alloy be made into barrel?
- No, hard alloy too hard too fragile, not processed, there should be a rifle barrel, it is difficult to machining.
- Q:How hard is the carbide knife?
- The sintering temperature of the cemented carbide is about 1200 degrees centigrade. The welding temperature of the tool copper is about 850 degrees, the brazing of silver is about 700 degrees centigrade, the temperature of the metal cutting point is about 800 degrees, and the cutting temperature of the woodworking will not exceed 100 degrees centigrade.
- Q:What is the heat treatment process of cemented carbide?
- To put it plainly, that is, hardening of cemented carbide, that is, heating to a certain temperature, insulation for a certain period of time, and then suddenly into the inert gas, so that it suddenly cooling.. The same as steel quenching. After quenching generally tempered, to eliminate the stress produced by quenching, it is mainly to change the bonding phase components, that is, the organizational structure, improve the strength of cemented carbide, hardness and comprehensive performance
- Q:Use of waste cemented carbide
- Two, crushing methodFor hard alloy containing drilling is not high, because the hardness is relatively low, can use manual or mechanical means broken to a certain fineness in wet grinding mill for a period of time, to reach a certain size for reproduction of hard alloy. This force is a method has the advantages of simple process, short process, low energy consumption, no pollution to the environment, but often in the manual crushing hard alloy, metallic materials due to debris into the tools have broken material pollution, in addition, due to the hard alloy drill containing high amount of easily broken, mechanical crushing method is very limited; cemented carbide complex material by this method is also very difficult to ensure the quality of recycled products. Process method: artificial crushing is broken, crushed into powder 200 mesh or using bulk of hard alloy ball mill for crushing strikes the ball, then add in the bjm alcohol in wet grinding, and then enter the remanufacturing process of hard alloy.Some companies use cooling method: first crushing waste hard alloy in a muffle furnace heated to 80 above this immediately into the water quench, resulting in hard alloy cracking, and then enter the mechanical crushing process. This force is a method in the last century in 90s in Hebei Province Qinghe to gain popularity, there were dozens of county size ranging from recycling plant using the recycled and processed hard alloy, hard alloy processed over a thousand tons of annual production, the total output value of 300 million yuan, becoming one of the local pillar industry. At present, there is still a certain space for development of the crushing method, and the crushing method still needs to be improved by adopting more advanced and clean crushing equipment or by means of the force method which does not destroy the microstructure of cemented carbide with high efficiency.
