流动粒子炉在国际上被预测为今后发展最快的三种炉型之一,它具有加热速度快、热效率高、节能节电和可实现无氧化无脱碳加热等优点。1985年我国初次将以液化石油气为燃料的内燃式流动粒子炉应用于生产,但对其加热特性、工艺参数、热处理效果以及适用范围等方面的研究还很少。本文根据对实际生产的考察和试验,对其热处理加热特性作初步分析。一、燃气流动粒子炉的工作特点济南西郊热处理设备厂生产的LQ型燃气流动粒子炉的结构如图1所示。它由炉体、气管路和测温系统三部分组成。炉体包
The flow particle furnace is internationally predicted to be one of the three fastest growing furnaces in the world. It has the advantages of fast heating, high thermal efficiency, energy saving and energy saving, and non-oxidation and decarburization-free heating. In 1985, for the first time, China’s internal combustion type mobile particle furnace using liquefied petroleum gas as fuel was used in production, but few studies were made on its heating characteristics, process parameters, heat treatment effect and its application range. This article based on the actual production of inspection and test, its heat treatment heating characteristics for a preliminary analysis. First, the working characteristics of the gas-flow particle furnace LQ type gas-flow particle furnace produced by the heat treatment plant in the western suburbs of Jinan, the structure shown in Figure 1. It consists of furnace, gas pipelines and temperature measurement system of three parts. Furnace package
