Problems solved by technology

However, there are many defects in the carbon potential control of the manual carbon potential control system: although there is no oxidation and decarburization on the surface of the material with manual carbon potential control, there is a case of carbon increase, because the carbon potential control is originally used in the carbon increase process Moreover, manual control has human error and instability
[0004] Moreover, the time of a spheroidizing annealing process is between 24-48 hours. It is difficult to pay attention to the change of oxygen potential by manual control during such a long period of ti

Abstract

The invention discloses an oxygen potential control system of a spheroidizing annealing furnace. The oxygen potential control system comprises an oxygen probe unit, a pressure sensor unit, an electric actuator, a data acquiring unit and a data processing unit, wherein the oxygen probe unit, the pressure sensor unit and the electric actuator are connected with the spheroidizing annealing furnace; the data acquiring unit is connected with the oxygen probe unit and the pressure sensor unit; the data processing unit is connected with output of the data acquiring unit; and through detecting and controlling the oxygen potential of the spheroidizing annealing furnace in real time, the oxygen potential in the spheroidizing annealing furnace can be detected and regulated in real time, and a situation, such as surface oxidation, decarburization or recarburization after a metal material is annealed is avoided.

Description

technical field [0001] The invention belongs to the technical field of spheroidizing annealing furnaces, and relates to an oxygen potential control system of a spheroidizing annealing furnace. Background technique [0002] With the rapid development of the steel industry, the market demand for medium carbon steel and alloy steel is increasing, and the quality requirements for medium carbon steel and alloy steel are getting higher and higher. Medium carbon steel and alloy steel are widely used in automobiles and aviation In industry, medium carbon steel and alloy steel are required to have high mechanical properties after annealing, and at the same time require steel to have good metallographic structure and spheroidized pearlite structure. Annealing is a metal heat treatment process, which will slowly heat the metal to a certain temperature, keep it for a sufficient time, and then cool it at an appropriate speed. It can achieve the purpose of reducing hardness and improving...
