Workpiece heating and well burning time prediction method based on gas consumption rate measurement

Abstract

The invention discloses a workpiece heating and well burning time prediction method based on gas consumption rate measurement, wherein prediction of heating and well burning time of single or batch of charged workpieces is mainly realized by measurement on the consumption rate of gas for a furnace. A gas heating furnace with a gas flow meter is used in the method, a needed heating temperature is set, single or batch of workpieces are placed in the gas furnace to be heated in a sealed environment, and the workpiece heating and well burning time is accurately predicted by measurement on the variation of gas consumption rate in the heating process. According to the method, a galvanic couple does not need to be buried at the center of the workpiece, the influence caused by workpiece shape and converter amount does not exist, the accurate prediction of the heating and well burning time of the workpieces can be realized, the operation is simple and convenient, energy is greatly saved and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of thermal processing of materials, and relates to a method for predicting the time of workpiece heating through-burning based on gas consumption rate calculation, which is suitable for heating and through-firing of workpieces in heating furnaces (including heat treatment furnaces) that use coal gas, natural gas and other gases as fuels. Burn time forecast. Background technique [0002] Thermal processing of materials is an indispensable link in mechanical manufacturing. While it is affirmed that it has the advantage of improving material properties, the huge energy loss caused by the heating process is also worthy of attention. At present, there is no relatively complete set of non-destructive prediction standards for the heating uniform time and holding time of workpieces (especially large castings and forgings). Zhang Zhong published an article "Measurement of Blow-through Time of Box-type Electric Furna...

AI Technical Summary

Problems solved by technology

In order to ensure the through-burning of the workpiece, the actual heating time is generally longer than shorter, resulting in reduced effective heat energy utilization, low production efficiency, serious energy loss and increased environmental pollution

At present, the uncertain time of workpiece through-burning and excessive heating time are the main reasons for the serious energy loss in my country's thermal processing industry.
