4 results about "High carbon" patented technology

A compactor tip (10) assembly for a landfill or soil compactor comprises a base (200) and a tip that are formed from dissimilar materials. The tip (100) may be formed from high carbon steel for wear resistance, while the base (200) may be formed from low carbon steel for easy welding. The compactor tip assembly is attached to the compactor wheel by welding the base to the wheel. The tip and the base each have ground engaging surfaces (101, 201) which may be complementary to one another. A hollow pocket (11) may be formed through the base and in the tip.

The invention discloses a heat treatment quenching technology for high-carbon chromium-molybdenum-vanadium powder hubbing steel precise parts. The technology comprises the following steps that 1, workpieces with the average thickness being 32 mm are put into a quenching furnace to be preheated twice to reach the temperature being 150 DEG C; 2, heating is conducted in the quenching furnace in two stages to reach the quenching temperature being 1,018 DEG C, and heat preservation is conducted; 3, the workpieces are subjected to discharge and air cooling till the temperature is 65 DEG C; 4, the workpieces are put into a tempering furnace twice, heat preservation and tempering are conducted at 510 DEG C, and discharge and air cooling are conducted. The workpieces with the average thickness being 32 mm are put into the quenching furnace to be preheated twice, for the first time, the temperature is raised to 100 DEG C at the heating speed smaller than 75 DEG C / hour, and for the second time, the temperature is raised to 150 DEG C at the heating speed smaller than 115 DEG C / hour. Accordingly, the excellent performances such as the extremely high abrasive wear resistance and high pressure resistance strength, good toughness and good size stability of heat treatment of the precise parts are reliably guaranteed, and the use requirements of the precise parts are met.
