由于供电的原因,我们厂只能在深夜炼三炉钢,炉盖经常处于激冷激热状态中,再加上炉盖砖的质量太差,名为高铝砖,实为较好的粘土砖,因此,使用寿命有几年时间都在20～30炉次,最高达40炉次。如何在这样的条件下提高炉盖的寿命?车间技术人员和工人进行了多方面的研究试验和对比,并参阅了国外有关科技资料,终于大胆地采用如下步骤: 一、改变砌砖的粘结剂 砌砖的粘结剂对炉盖的使用寿命有很大的关系。关于电炉炉盖的砌砖粘结剂曾经历了两个阶段。75年以前为粘土粉加水玻璃和水。75年以后为高铝加磷酸和水。以上两种粘结剂都
Due to the power supply, our factory can only heat three furnaces in the middle of the night. The furnace cover is often in a state of chilling and heat. When the quality of the furnace cover brick is too poor, it is called high alumina brick, which is actually better clay Brick, therefore, the service life of a few years in 20 ~ 30 heats, up to 40 heats. How to improve the life of the furnace cover in such conditions? Workshop technicians and workers carried out a wide range of research experiments and comparison, and refer to the relevant foreign scientific and technological information, and finally boldly adopt the following steps: First, to change the bonding brick Binder brick binder on the life of a great relationship. Bricklayers on the furnace lid have gone through two stages. 75 years ago for clay powder plus water glass and water. After 75 years for high-aluminum add phosphoric acid and water. Both of the above binders are
