Heat treatment workshop

The heat treatment workshop of CHANGTAN is a member unit of China Heat Treatment Association. Since its establishment in 1958, through the continuous efforts of several generations of long-term exploration and heat treatment, it has been able to undertake heat treatment and surface treatment businesses such as quenching and tempering, quenching, normalizing, annealing, carburizing, high-frequency, nitriding, aluminum quenching and aging. In 2003, it was moved from Shuguang middle road of Changsha to Xingsha Economic and Technological Development Zone of Changsha. According to the requirements of modern plant design, the original equipment was thoroughly overhauled and updated, and the quenching medium circulation system was added. In addition, the perfect hardness and metallographic testing methods greatly improved the stability and reliability of the quality of heat treatment products. In 2004, it passed ISO9001:2000 quality management system certification.

The main equipment and processing capacity of Hunan Mega Drilltech Co., Ltd heat treatment workshop are as follows:

1、 Box type resistance furnace

Specification: rx3-45-9, rx3-60-9, rx3-75-9, rt2-85-9

It can undertake quenching, normalizing, annealing, tempering and other processes, and the maximum length of the workpiece can reach 1600mm.

II. Well type gas carburizing furnace

Specification: rjj-75-9

It can undertake carburizing of various gears and shaft parts.

III. ldmc-75f touch screen computer full process control pulse power supply glow ion nitriding furnace

Specification: ldmc-75f

The effective working area size of the furnace body is: Ф nine hundred × one thousand and four hundred

It can undertake surface nitriding and nitrocarburizing treatment of various nitrided parts such as internal and external gears and shafts.

IV. high frequency quenching equipment

Specification: gp-100c2 gp-100c3

　　Our high-frequency equipment quenching machine has one vertical and one horizontal, which is highly versatile.

　　Gp-100c3 cooperates with the newly purchased advanced gcls-1605dd CNC vertical quenching machine tool to conduct high-frequency quenching on the inner and outer surfaces of various gears, shafts and special-shaped parts. The maximum diameter of the quenched workpiece can reach Φ 500mm, and the longest quenched workpiece length is 1620mm. Through the numerical control system, the high-frequency quenching process parameters can be accurately controlled. With the frequency conversion speed control system and relevant executive parts, the product quality stability and reliability can be greatly improved.

　　Gp-100c2 can quench the outer surface of up to 6000 shaft parts with horizontal quenching machine.

V. testing equipment

The main testing equipment includes Brinell hardness tester, Rockwell hardness tester, inner hole Rockwell hardness tester, surface Rockwell hardness tester, Richter hardness tester, metallographic microscope, chemical composition testing equipment, etc.

Changtan heat treatment personnel, adhering to the consistent fine tradition, with advanced technology and reliable quality, warmly welcome new and old customers to our factory for outsourcing processing.
