摘要
对电工钢的市场需求,在过去的几年里显著增长,并且这种趋势还在持续。这种增长的趋势同时适用于取向电工钢(GO)和无取向电工钢(NGO)。电工钢作为一种高质量的产品,在其生产过程涉及到了一些工艺技术上的制约。也许其中至关重要的一个方面是取向硅钢的高温退火。这种高温退火工艺在亚洲多为使用环形炉(RBAF)进行,而在欧洲和美洲则仅使用多垛式罩式退火炉(MBAF)。MBAF一个主要的缺点是使用电加热造成较高的运行成本。为此,LOI开发了燃气加热的多垛式罩式退火炉,并成功运用到了实际生产中,其无论在退火质量,还是在运行成本方面,均成为环形炉强有力的竞争设备。多垛式罩式退火炉已经通过了生产测试一这种燃气加热的多垛式罩式退火炉已经有了5年的实际生产过程。所有当初设定的目标值均已达标。本文详细论述了LOI公司所开发的高度复杂的燃气加热多垛式罩式退火炉、环形炉和罩式炉之间的概要及生产结果上的比较、及电加热和燃气加热多垛式罩式退火炉之间的比较。
The demand for electrical steel has grown significantly over the past years and is expected to continue to grow.This applies to both,grain-oriented(GO) and non-grain-oriented grades(NGO).Electrical Steel is a high quality product with quite some technological constraints involved in its production.Probably one important aspect in this respect is the high temperature annealing of grain oriented silicon steel.Such high temperature annealing will be done in Asia mostly in Rotary Furnaces(RBAF) while in Europe and America only Multi-stack Batch Annealing Furnaces(MBAF) are used.Major disadvantage of MBAF's are the higher operating costs by using electricity as heating medium.LOI has developed and successfully put into production gas-fired Multi-stack Batch Annealing Furnaces which are absolutely competitive to Rotary Furnaces in regard to annealing quality and operating costs.The practice test has been passed-the first gas-fired Multi-stack Batch Annealing Furnace Plant is in operation for more than 5 years.All initially set targets have been met.The article describes the high sophisticated LOI-development with a detailed description of the gas-fired MBAF-technology,a general comparison between Rotary Furnaces and Batch Furnaces as well as operating results and comparison between electrically heated and gas-fired Multi-stack Batch Annealing Furnaces(MBAF's).
