Equipment Overview

The isothermal quenching furnace is primarily used for quenching mechanical workpieces using various salt solutions and mixed salts as the quenching medium. The equipment is structurally similar to a general quenching tank, made of steel plates in square or round shapes, heated by electric heating tubes to melt the salt solution. It is equipped with a circulating pump, a stainless steel plate heat exchanger, and an automatic temperature control cabinet. The quenching salt temperature is maintained at the process quenching temperature within a closed-loop cooling water system, in conjunction with an automatic temperature control system.

Configuration Features

An electric reciprocating swing feed trolley is installed on the furnace body, with workpieces placed in the trolley and reciprocating in the nitrate salt solution. A stainless steel compressed air inlet pipe is also provided. At the bottom of the crucible, a porous jet pipe is formed to rapidly circulate and agitate the nitrate salt solution. Precise temperature control is achieved through an automatic temperature control cabinet, ensuring uniform temperature throughout the nitrate salt solution. Additionally, four rapid cooling packs are configured inside the isothermal quenching furnace, enabling the quenched workpieces to be rapidly cooled to the required process temperature for isothermal quenching in a very short time, maintaining automatic isothermal control.
