本文根据硅砖和粘土砖的线膨胀曲线,联系本厂多年来烘炉的实践.提出了一条可减小炉体内部的热应力、保持炉体结构的整体性和气密性的烘炉升温曲线。1.前言钢丝热处理马弗炉(以后简称炉子)是中、高碳钢丝和钢丝绳生产厂家的主要热处理设备。新建或者经过大修的炉子,一定要先按照规定的烘炉升温曲线进行 Based on the line expansion curve of silica bricks and clay bricks, this paper relates to the practice of ovens in our factory for many years.An oven heating curve which can reduce the internal thermal stress of the furnace body, maintain the integrity and airtightness of the furnace body structure, . 1. Introduction Wire heat treatment muffle furnace (hereinafter referred to as the furnace) is the main heat treatment equipment for medium and high carbon steel wire and wire rope manufacturer. New or after overhauling the stove, be sure to follow the provisions of the oven temperature curve
