一、概述热处理加热炉的种类是多样的,按热源可分电炉和燃料炉两类。燃料炉又可分为固体、液体和气体燃料炉三种。其中采用煤气等气体燃料为热源的气体燃料炉不仅造价低、燃气经济,而且便于调整和控制炉温及炉内气氛,因此大型加热炉一般多用气体作为热源。随着世界范围能源的紧缺,很多国家的热处理设备进行了以提高效益和节约能耗为中心的技术改造。就气体燃料炉的发展来看,利用炉内废气余热再循环的方式是热处理炉节能技术发展的一种方向。本文介绍武钢冷轧薄板厂从比利时EUROFOURS炉子公司引进的强制循环节能型台车炉设备结构、特点和控制情况,为同类企业开展以节约能耗为中心的技术改造提供了一种新的借
First, an overview of the types of heat treatment furnace is diverse, according to the heat can be divided into electric furnace and fuel furnace two categories. Fuel can be divided into solid fuel, liquid and gas furnace three. Among them, the gas-fired fuel furnace using gas fuel as a heat source is not only low in cost and gas economy, but also easy to adjust and control the furnace temperature and the atmosphere in the furnace. Therefore, large-scale reheating furnace generally uses gas as heat source. With the shortage of energy in the world, the heat treatment equipment in many countries has carried out the technological transformation centered on improving efficiency and saving energy. Gas furnace on the development of view, the use of waste heat recycling furnace waste heat treatment furnace is a way of energy-saving technology development. This paper introduces the structure, characteristics and control of forced-cycle energy-saving trolley equipment introduced by the Belgian company EUROFOURS Furnace Company from WISCO cold-rolled sheet mills, providing a new kind of technology for the similar enterprises to carry out technological transformation centered on energy conservation
