Comparing with traditional oil quenching,nitrate quenching has some advantages,including high quenching temperature,small deformation of the work pieces,safety and that the nitrate is not easy to aging and can be recovered.

The temperature uniformity of a big tempering furnace.;

The new type high temperature electricity heating salt-bath tempering furnace mainly consisting of thermal couple furnace body, heater, control cabin,have the following advanges: power saving, copper material saving, structure simple, the temperature inside difference less and the quality of work piece remain steady.

In order to save natural gas consumption,a series of energy-saving technologies were adopted in the steel pipe heat treatment quenching furnace and temper furnace,so that the energy-saving effect was good.
