Carbon potential operator

Abstract

The invention discloses a carbon potential operator which comprises a main controller and a mode setting unit. A programmable logic controller serves as the main controller. The main controller comprises a first carbon potential operation unit and a second carbon potential operation unit. The first carbon potential operation unit comprises a first temperature signal input interface, a first carbon potential signal input interface, a first carbonic oxide signal input interface and a first carbon potential output interface. The second carbon potential operation unit comprises a second temperature signal input interface, a second carbon potential signal input interface, a second carbonic oxide signal input interface and a second carbon potential output interface. The mode setting unit is connected with the first carbon potential signal input interface, the first carbonic oxide signal input interface, the second carbon potential signal input interface and the second carbonic oxide signal input interface. By means of the carbon potential operator, the using convenience and calculation accuracy of the carbon potential operator are greatly improved.

Description

technical field [0001] The invention relates to the field of heat treatment equipment manufacturing, in particular to a carbon potential calculator. Background technique [0002] In the carburizing equipment for heat treatment, it is necessary to measure and manage the parameters of the carburizing ability in the furnace (referred to as "carbon potential"), the carbon potential and the temperature of the atmosphere in the furnace, the content of carbon potential gas (carbon dioxide or oxygen) and carbon monoxide content is closely related. According to the type of carbon potential gas selected, the characterization methods of carbon potential include oxygen potential method and carbon dioxide potential method. The oxygen potential method can be expressed by the expression Cp=f(T, O2, CO), while the carbon dioxide formula can be expressed by The formula Cp=f(T, CO2, CO) represents, where: Cp represents the carbon potential in the furnace atmosphere, T represents the temperat...

Problems solved by technology

[0003] The measurement and calculation of carbon potential is a very complicated process. Therefore, special carbon potential controllers are generally used to achieve the purpose of carbon potential measurement and management. Most of these special carbon potential controllers are specially developed with single-chip microcomputers or It is completed by a computer with special software. Due to the high development cost and small production quantity, the price is very expensive, which affects the promotion and application of the product to a certain extent.

In addition, the existing carbon potential controller generally only has one carbon potential calculation unit, and its calculation accuracy is difficult to guarantee
