What is the feature of bkh47 teeth?
1. It is effective against abrasion working condition.
2. Working process doesn't produce high temperature and spark.
What is the advantage of bkh47 teeth?
1.Long service life. Its service life is 1-1.5 time than traditional cutting teeth;
2.High efficiency. Its working efficiency is 2.5 time than traditional cutting teeth;
3. Good energy efficiency. Replacing frequency dropped substantially, shortens the coal winning machine downtime,reduce the mining cost.
What is the quality standard of bkh47 teeth?
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 companies YG10C, stable quality can accord customer needs to add welding wear-resisting layer, hardness reaches more than 65 degrees.
