Technical Supports

The factories of CNBM invested 2.3 billion RMB for large-scale technical innovation during the “Eleventh Five -Year Plan”. Our company has completed equipment and technology upgrade transformation at the end of 2008, which was concentrated on three projects, production line of centrifugal casting rolls for hot strip and plate mill, forged roll for cold/hot strip mill, national class technology center and roll material lab. Through upgrade transformation, the following targets have been achieved:

(1) It becomes the world’s biggest specialized mill roll maker with the largest production scale, the most complete specifications of products and the most extensive coverage of various rolls used on rolling mill. 

(2) The technology of equipments has reached international leading level.

(3) “Mechanization, automation, intellectualization, digitization” of equipments obviously improve the quality control ability.

(4) New types of research instruments improve the R&D capacity of products.

Q:Why are powder metallurgy parts generally small?
Most of the forming technologies of powder metallurgy products are pressing forming and injection molding, which limits the size and shape of parts.
Q:How to strengthen the shock resistance of powder metallurgy metal parts?
Sintering technology should be excellent, if possible, hot isostatic pressing (low pressure) sintering furnace sintering, the stress is small, uniform structure.
Q:How can make powder metallurgy machinery fittings have hardness, toughness?
The methods are as follows:Increasing the density of powder metallurgy parts.
Q:What is the manufacture of powder metallurgy machinery parts?
Powder metallurgy is similar to the production of ceramics, all belong to powder sintering technology. Therefore, a series of powder metallurgy new technology can also be used for the preparation of ceramic materials. Because of the advantages of powder metallurgy technology, it has become the key to solve the problem of new materials and plays an important role in the development of new materials.
Q:Why does the aspect ratio of powder metallurgy machine parts need to be controlled?
The traditional unidirectional pressing leads to uneven density distribution, which leads to the limited ratio of height to diameter, and to friction compaction.
Q:What kind of high temperature anticorrosive coating is used for metallurgical high temperature parts?
High temperature paint, if not thermal shock, easy to crack, and more functions can not be achieved.
Q:What are the types of powder metallurgy machinery parts?
There are two kinds of powder metallurgy parts forming: press forming and injection molding.
Q:What kind of imported metallurgical machinery parts do steel mills need to rely on?
Basically, the technical content of high quality, good import, I do not say one by one, too much.
Q:What is the cost of the powder metallurgy machine parts?
The cost of raw materials, auxiliary materials, generally by the artificial and manufacturing cost etc.. Powder metallurgy. The material must be lower than the casting parts. I think it is equivalent to adding a casting process from powder metallurgy to an ordinary casting part.
Q:Process flow of powder metallurgy parts plating
Prior to the powder metallurgy electroplating, the utility model needs baking, deoiling and sealing the pores, and thoroughly cleaning and drying after plating. At the same time, all kinds of treatment solution should be chosen as low as possible.
