一、概述 硅钢板、镀锌原板、不锈钢板、铝板及其合金制成的各种带钢均在连续热处理炉进行热处理。入炉带钢借助于分组集体传动的炉底辊,从入侧输送到出侧,在约800～1050℃的炉温和特定的气氛下,完成一定的热处理工艺过程。 该连续热处理炉的无氧化加热段,用来对入炉带钢进行快速加热,炉温通常控制在1100～1300℃,因此,一般采用辊身水冷或空冷的炉底辊,带钢在该段温度升至约500～550℃,然后进入辐射管间接加热的加热段。
First, an overview of silicon steel, galvanized original plate, stainless steel, aluminum and its alloys are made of a variety of strip in a continuous heat treatment furnace for heat treatment. Into the furnace with the group by means of grouping furnace bottom roller, from the entrance side to the delivery side, at about 800 ~ 1050 ℃ furnace temperature and the specific atmosphere, to complete a certain heat treatment process. The continuous heat treatment furnace without oxidation heating section, used to carry out rapid heating of the incoming strip, the furnace temperature is usually controlled at 1100 ~ 1300 ℃, therefore, the general use of roller water cooling or air-cooled bottom roller, strip in the paragraph The temperature is raised to about 500-550 ° C and then into the heating section where the radiant tube is indirectly heated.
