TYHI is a leader in heat treatment; we own different kinds of shaft type and trolley type heat treatment furnaces. For electric heating heat treatment furnaces, the uniformity of the furnace temperature can be controlled within the range of ±5℃. We can undertake heat treatment for machinery products, matching parts for mines and factories, heavy forgings, forgings used for power stations, pressure vessels and military products. We can also carry out normalizing, annealing,hardening and tempering, quenching, industry-frequency, medium-frequency, superhigh-frequency and high frequency case induction heat treatment and chemical heat treatment such as carburizing and ionic nitriding for different kinds of products.
