Q:What reason is the bronze statue choking fire?
The casting process in boiling phenomenon, is the setting of the exhaust hole positioner position or number is not reasonable, the air cavity can not be discharged, overwhelmed by a material inlet, reflux, change mould, sincerely help you look forward to adopt,
Q:Younger brother is to do casting valve, precision casting parts, the valve internal sand serious, but the appearance is very standard, this is why, for God answers, thank you!
Increase the refractoriness and looseness of core sand
Q:Lathe processing stainless steel casting parts to use what type of tool, the speed into the amount of how much tool angle
Processing stainless steel materials, you can use YG class tools, such as YG8, YG8N. The tool geometric parameters g0=15 degrees to 18 degrees, a0=6 degrees to 8 degrees, kr=75 degrees, ls=-5 degrees to -8 degrees; cutting amount is Vc=43 m/min, ap=0.3 to 0.5 mm, f=0.16mm/r.
Q:Why does the surface of stainless steel casting mirror mirror ripple?
The surface can be improved by a little more than Xiasha
Q:We are small castings, the need for surface treatment of shot blasting machine, about how much?
The choice of shot blasting machine, this is according to the workpiece size, yield, whether can collision, and the working time and other factors considered, while the price of different blasting machine are not the same, but the vast majority of small castings used crawler shot blasting machine, according to the comprehensive consideration of factors such as yield, size of workpiece commonly used on the market the crawler shot blasting machine has Q324, Q326, Q328, Q3210, and each time the amount of their treatment were 125KG, 200KG, 400KG, 600KG, the specific use of what types also need to be determined according to the actual situation
Q:In theory, which is more expensive, forging parts or casting parts?
It depends on the structure. In theory, the shape of the forging is relatively simple, but the requirement of internal structure is relatively high
Q:How can the casting be quenched and tempered?
Another is the result of pre heat treatment (quenching or annealing) after quenching and tempering treatment, suitable for ZG35SiMNMo, ZG35CrMo and so on. Please tell the casting process is your product and material and then set tempered.: shutup:
Q:Where is the precision casting factory?
Everywhere is. Look what you want to do
Q:The casting defects of pores, trachoma how to repair?
Airhole above 2mm recommended LT101 casting defect repair agent. If repair quality requirements, high availability LT111 iron repair agent, LT112 steel repair agent, LT113 aluminum repair agent, LT114 copper repair agent.
Q:Explain the heat treatment effect of casting parts, forging parts and welding parts
Good welding of low carbon steel (alloy), probably because the weld workpiece rigidity, fast cooling, the weld internal crystallization of brittle microstructure (martensite), so after welding or welding process welding using self heat, reasonable arrangement of weld, welding seam and heat affected zone heat treatment. The welding heat treatment is often used to preheat before welding, after welding withasbestos cloth covering slow cooling annealing, reach the purpose, its main function is to reduce the internal stress, improve the weld microstructure of martensite formation, reduce brittle tendency, preventing welding cracks.
CGBM established in 1995, the largest and most specialized casting and forged products supplier in China. Min products are grinding media balls, grinding rods, cylpebs, mill liners and steel flanges, with specifications all reaching international standards and annual production capacity is over 150,000tons.
