VKD as a more than 6years history high-tech company is always
concentrating on the production and research of cemented
carbide.the picks we are manufacturing are used widely in the field
of mining and construction etc.
Cemented carbide:Tungsten and Cobalt
Cemented carbide which has high hardness and toughness and high
wear resistance and corrosion resistance attributes is widely used
in the field of military projects,mechanical processing,metallurgy
technology, oil exploiting,electronic communication etc.
The technology and production equipment are developing
unprecedented during these years along with the continuous
upgrading of manufacturing industry in China and the research and
innovation of new engineering material. The quality of cemented
carbide of VKD is able to compete with those lending manufacturers
and famous brands in the world.
Pick for mining
Pick are one of the quick-wear parts in the coal mine and tunnel
excavation its performance decides the machine's production
capacity and power consumption and working stability and the
working life of other spare parts.It is the main tools which cut
the coal and break coal. The popular grade of steel is 42CrMo,
The hardness of the body of pick is 40-45HRC, impact tenacity not
less than 49J/cm2.
The tooth body is made of high quality cold extrusion 42CrMo, high
density not decarburization. Numerical control lathe processing
ensures consistent size. With special heat treatment process of
40-45 degrees, its surface is almost no oxidation, tooth head using
isothermal quenching process, its hardness doesn't reduce.
Production of cemented carbide by formal domestic companiesYG11C,
stable quality can accord customer needs to add welding
wear-resisting layer, hardness reaches more than 65 degrees
Our coal cutting picks bits are in all sizes, mainly used in coal
mining and roadway, tunnel, the ground trenching engineering
excavation, such as the main blending coal winning machine, boring
machine, milling planer and other equipment.
