4. Packing Methods of High Chrome Grinding Media Ball with High Hardness & Good Wear Resistance & High Toughness & No mal-roundness
- 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: What are the requirements for casting steel castings?
- 2, the plane should be placed on the following.3, thin parts should be placed below.
- Q: What is the ejection angle of the die casting (Tan Gang)?
- Because after the wax, wax parts will have a slight contraction, which is good for demoulding. Many moulds don't do the ejection angleEspecially deep hole, and customers to discuss, generally take 0.3-1 degrees is enough
- Q: Domestic large steel castings factory which is better, recommend!
- Do the casting manufacturer of large steel castings, Hunan Jinsha heavy industry science and technology limited company, heard that their professional only more than 1 tons of steel castings, anyway, 150T just big, the company won a lot of foundry industry patents should be good.
- Q: What kind of casting process is used for cast iron parts? And what are the cast steel parts adopted?
- The main content of red sand table (Institute of soil science, China) silica 79.4%. three 1.48%. three 10.55%. two aluminum oxide iron oxide, calcium oxide 0.85%. Magnesium Oxide 0.52%. 1440. refractory mud 3.06% LOI 1.98% red sand with high silicon content, permeability is strong, durable, high refractoriness, good angle, low moisture content, less mud the casting finish is high, the basic requirements of sand should meet the following requirements: Casting of high purity and cleanliness, with silica sand as an example, iron sand SiO2 content of more than 90%, the big steel casting requests the SiO2 content of more than 97%; the high refractoriness and thermal stability; the suitable particle the shape and particle composition; it is not easy to be wetted by the liquid metal; cheap. The particle shape and composition of casting sand particle shape and particle composition permeability properties such as mobility, sand compaction, permeability, strength and resistance to liquid metal effects, is an important indicator of the quality of casting sand.
- Q: The difference between cement sand castings, resin sand castings and vacuum casting parts
- The clay wet sand castings casting weight from a few kilograms until tens of kilograms, but the clay dry type of casting production can be weighed dozens of tons.For medium and large castings, cast iron, cast steel can be self hardening sand with resin can be water glass sand production, can obtain the precise size, smooth surface castings, but casting precision, surface roughness, density and microstructure, mechanical properties and material cost of sand casting production is often poor, so when the higher performance requirements of castings, should adopt other casting methods, such as casting (lost wax casting), die casting, low pressure casting.
- Q: What should I pay attention to when designing a casting structure?
- 1 of the casting in metal mold cooling was faster than sand, metal type and let, thus casting in metal mold casting, casting stress generated in the ratio of sand casting to crack tendency is also large, but also prone to misrun and cold lap, white (for casting casting). Defect. Usually: (1) in the prevention of metal casting casting crack aspect should pay attention to the following problems: the structure of A in wall thickness, wall transition and connection to the ease, corner fillet appropriate requirements such as should be more strict than sand casting; B should be connected vertically connected with the wall to tilt C; for the weak parts of the structure should be set to strengthen ribs, bosses, to prevent casting; D should minimize the obstacle free shrinkage of the boss, casting rib, flange and other prominent part; E in the casting arrangement of ribs, but also should consider its influence on the casting shrinkage.
- Q: For example, casting parts contain many holes, inclusions and other defects, the size and the number of holes exceed which limit is not qualified
- For example, the castings shall be in accordance with the requirements of the second types of castings in the technical requirements for aluminum alloy castings of GB/T9438-1999;
- Q: Lathe processing stainless steel casting parts to use what type of tool, the speed into the amount of how much tool angle
- There is YW1 best, if not using YG6X, YG8 is ok!The speed should not be high, the greater the diameter, the lower the speed! For example, a diameter of 100 mm, speed is not greater than 80 rpm, each point is good!The main tool is the front angle to be larger, more than 6 degrees, and the groove should be wider and larger to reduce the cutting resistance! When the rear angle is properly reduced and the strength is increased, it is recommended to take 3 degrees.The main components are: spindle box, exchange gear box, feed box, slide box, tool post, tail frame, light bar, lead screw, bed, foot and cooling device.Spindle box: also known as the headstock, it is the main task of the rotary motion of the main motor came through the transmission mechanism of a series of positive and negative spindle to be required two different steering speed, the spindle box gives impetus to the movement of the box. Medium spindle is the key part of lathe. The stability of the spindle on the bearing directly affects the quality of the workpiece. Once the rotation accuracy of the main shaft is reduced, the value of the machine tool will be lowered.
- Q: Shandong foundry, casting small pieces of precision casting
- Dongying Huayang precision casting factory, the smallest to do 2G pieces.
