High Chrome Alloyed Casting & Forging Bar

Q: What is normalizing, annealing, tempering, quenching? What is the difference between forging parts and casting parts?: For the nodular cast iron, the hardness, strength and wear resistance are improved, such as used in the manufacture of automobile, tractor, diesel engine crankshaft, connecting rod and other important parts. A normalizing and hypereutectoid ball annealing before, can eliminate the mesh two cementite spheroidizing annealing, to ensure that all spheres of cementite. Annealing is a metal heat treatment process, which means the metal is slowly heated to a certain temperature, sufficient for a long time, and then cooled at an appropriate speed. The purpose is to reduce hardness, improve machinability, eliminate residual stress, stabilize size, reduce deformation and crack tendency, refine grain, adjust microstructure and eliminate tissue defects. Its purpose: (1) reduce hardness and improve machinability; (2) eliminate residual stress, stabilize size, reduce deformation and crack tendency; (3) refine grain, adjust microstructure and eliminate tissue defects. In production, annealing process is widely used.

Q: The casting defects of pores, trachoma how to repair?: Metal repair can be used to fill the repair. Airhole 2mm following LT102 recommend the use of liquid metal repairing agent.

Q: What is the reason for 304 stainless steel precision casting parts to be changed?: 304 stainless steel is easier to change than ordinary steel. Because the 304 heat conductivity is lower than that of the low doped steel, the temperature is even more uneven, and 20% of the non ferrous elements also make the distribution of internal and external elements more uneven, hard and soft inside. Each of these two produces greater internal stresses, resulting in a variant.

Q: After reaming, the roughness can reach several levels, that is to say, the sample.Casting parts in rocker arm drilling, reaming, roughness, block. After reaming, the roughness can reach several levels, that is to say, the sample.: The finish of reaming depends on the material and the sharpness of the reamer, as well as the speed and speed of the top and bottom. Marine machine tool

Q: What are the causes of pitting on the surface of a precision casting?: There is a bump on the mold. Or casting cooling fast.

Q: Heat treatment process and purpose of casting parts: Methods: artificial aging or natural aging (also called normalization) treatment.Artificial aging: heating to 2-3 Baidu, it is best to apply mechanical vibration, and maintain a period of time.

Q: What are the general technical requirements for casting parts?: Satisfy appearance quality (appearance defect, quality change, size deviation)Intrinsic quality (composition, properties, internal organization)Service performance (abrasion resistance, corrosion resistance, heat resistance, pressure resistance)

Q: When the blank is a casting, the margin is evenly distributed, how should rough machining?Please help friends from mechanical classes.There is another problem: in the NC milling plane contour machining, when the rough margin is large, how to deal with.Who can help in time, add 20 reward. Urgently!!: Problem one,1, according to drawings, castings, material requirements and machine power, choose the right diameter of roughing tools, and can process this material blade type.2, according to the actual size of the casting blank, calculate the number and path of the knife, pay attention to small cutting depth, large feed, cutting width, to ensure that the tool diameter 80 - 90%, the amount of not full knife cutting, this tool and machine tool damage.Question two,If they can not change the casting blank allowance under the condition that the quantity large diameter cutter, such as milling cutter main angle 7560 degrees can give reasonable processing parameters, the same cutting depth should not be too large, because in the same machine power, tool diameter increases, cutting depth will need smaller.

Q: Shandong foundry, casting small pieces of precision casting: Dongying Huayang precision casting factory, the smallest to do 2G pieces.

Q: The difference between sheet metal and casting parts: Commonly used in machine tools casting material is gray cast iron, casting bearing alloys can also be.
