Background

The slag guide plates under the converter are generally arranged at two sides of the converter foundation, the angle of the slag guide plates is generally 45 degrees, and the slag guide plates are used for guiding the steel slag dropped during the working of the converter and are collected in the slag pit under the converter.

At present, the conventional slag guide plate device under the converter has two forms, wherein one form of the slag guide plate is steel structure truss and heat-resistant cast iron plate, and the slag guide plate is fixed on the side wall of the converter foundation through bolts; another form is to integrate with the converter foundation to form a reinforced concrete form, and to lay an cast iron plate on the reinforced concrete slope. The steel structure truss has the advantages of convenient replacement, no bearing of impact of massive steel slag, easy deformation, short service life, frequent replacement and higher cost. Due to the disadvantages of the first form, the second slag guide plate form is derived. The second mode is that the cast iron plate is directly fixed on the concrete foundation through bolts, and has the advantages of being capable of bearing the impact of large steel slag falling down after a furnace, long in service life and not needing to be replaced frequently. However, as the slag guide plate bears high temperature and heavy impact for a long time, the cast iron plate is deformed and the bolts are broken in the use process, so that the cast iron plate slides down to the terrace, vehicles or terrace rails under the furnace are easy to smash, potential safety hazards exist, the service life of the cast iron plate is influenced, and the replacement is difficult.
