Good Wear Resistance And No Reakage Forged Grinding Ball

Forged (hot rolled) grinding media steel balls for mining, cement plant, power station, chemical industry.

Features of Good Wear Resistance And No Reakage Forged Grinding Ball

1.High hardness, and hardness gradient uniform distribution.

the volume hardness more than 60HRC, which grantee the balls with good roundness during working.

2.Low breakage rate, the breakage rate of ball is less than 1%.

3. Good mechanical properties, in processing, the balls quenched in water, subsequent tempering.

Keep the ball under 180~220 Celticism, make the ball have good impact properties

Good Wear Resistance And No Reakage Forged Grinding Ball

Q:Casting parts have poor surface finish. What sand is used to make them?: Now resin sand, coated sand and other processes are also very good surface.

Q:When there is no flaw detection for large casting parts, is there any crack inside?: According to the industry standards, within the scope of the standard requirements to determine whether the product is qualified

Q:How can the casting be free of trachoma?: Measures for the prevention of trachoma in castings:1, sand compaction to high, paint two times;

Q:What method of casting does not rust? I think the sample is like oil: The surface of a general casting is easy to rust. In order to prolong the rusting period, antirust paint or antirust oil is usually sprayed. What you said should be anti rust oil.

Q:How do casting parts remove stress?: Annealing treatment, according to different casting annealing treatment, eliminate thermal stress, if need to restore hardness or increase hardness, and then quenching treatment

Q:How much is the amount of electrophoretic paint per square meter used in the casting?: In general, when the final thickness of 15-20 microns, cathode electrophoresis paint can be coated per kilogram of 6-8 square meters, the current general cathode electrophoresis paint for the price of 22 yuan / kg, so the cathodic electrophoresis electrophoresis paint cost at 4 yuan / square meters.

Q:What is the casting material?: The casting material is usually made of gray cast iron, nodular cast iron and vermicular graphite cast iron

Q:How do you mark it on the drawing? Do you need to discuss it with the manufacturer?Because the casting allowance is the standard, then, after all, is the theoretical value, the actual level depends on the manufacturer, so is it necessary to ask the manufacturer?: Casting parts do not need to provide drawings of casting blank, the casting factory according to your drawings in the required surface will be sufficient allowance, and the rest of the size according to the mechanical design manual and the casting manual can be found. The general foundry casting technology division will mark put shrinkage and the allowance of the map in your chart (usually with the red pen) for the production of wood or other material wood workers die drawings.

Q:What is normalizing, annealing, tempering, quenching? What is the difference between forging parts and casting parts?: According to the requirements of the workpiece annealing, there are many kinds of annealing process specifications, such as full annealing, spheroidizing annealing and stress relieving annealing. Steel the steel quenching is heated to the critical temperature Ac3 (hyposteel) or Ac1 (hypereutectoid steel) above a certain temperature, holding time, so that all or part of 1 Austenitic, then the cooling rate is greater than the critical cooling rate of fast cooling to below Ms (or near Ms isothermal) of martensite the body (or bainite transformation) heat treatment process. Aluminum alloys, copper alloys, titanium alloys, tempered glass and other materials are usually treated by solid solution or heat treatment with rapid cooling process. Tempering is a heat treatment process where the workpiece is hardened and heated to a temperature below AC1, which remains cool for a certain period of time and then cools to room temperature. Tempering generally followed by quenching, the purpose is: (a) to eliminate the residual stress caused by quenching, prevent deformation and cracking; (b) hardness, strength, plasticity and toughness of workpiece is adjusted, to use performance requirements; (c) the size of organization and stability, ensure the accuracy improvement; (D) and to improve the processing performance. Tempering is therefore the last important step in obtaining the desired properties of the workpiece. According to the tempering temperature range, tempering can be divided into low temperature tempering, medium temperature tempering and high temperature tempering. This answer is recommended by the questioner

Q:Is 316 casting better than 304 casting?: It is comprehensive. There is no simple comparison of the material to determine the degree of difficulty in processing
