3.Packing Methods of Casting Alloy Grinding Ball Used for Mine & Cement with Dia0.75’’-Dia6’’ & High Hardness HRC60-HRC65

Q:How to get rid of casting sand inside casting parts?
Are you saying that in the sand casting cavity? We use the manual blast, he is like a pipe will be automatic shot out of the grit, into the casting cavity, to remove the internal cavity in the purpose of casting sand!
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,
Q:Casting parts have poor surface finish. What sand is used to make them?
Manual coal dust, clay sand is a little worse. Mechanical styling is not bad either.
Q:Which master knows how the casting tolerances for malleable iron, gray iron and ductile iron should be chosen? Hurry up, thank youCan you provide a tolerance scale for castings, please?
The tolerance of a specific size can be obtained from the tolerance grade and nominal size of the casting.
Q:What's the cause of the choking of the casting?,
Causes of choking fire:1., casting material in the pouring of gas;
Q:In the design of casting steps and precautions, for casting design, we have what experience?.
Two: the basic structure unit in the design of metal casting type and the parameters selected, usually should also pay attention to: (1) because of the metal type heat quickly, so the metal type casting minimum wall thickness should be bigger than the sand casting, metal type casting alloy minimum wall, different size of castings see table 1.1-31 thick can be selected; (2) the inner wall of the casting internal ribs and the thickness of wall thickness should be 0.6-0.7 connected, or as the inner wall (rib) cold slowly, cracks in the wall at the junction in the casting shrinkage;
Q:Why do casting parts have air holes?
Cangshan Qiao hidden his answer is quite comprehensive, you can try using inert gas to reduce air cover
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.
Radial drilling machine can achieve boring, reaming function, but as much as you want, according to your requirements and material to determine!
Q:How to calculate the price of casting parts?
Cost of raw materials + electricity (fuel) costs + workers' wages + managers' wages + transport costs + raw materials burned + accessories costs + equipment maintenance depreciation costs + management fees + tax. The most convenient, the raw material market price plus 2000 yuan, plus you want profits on the line.
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.
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.
