Intermediate frequency furnace ramming material through the furnace

Many companies use different ramming materials when they are blasting furnaces, and different ramming materials have different functions. So it is very important to use intermediate frequency furnace ramming materials to blast furnaces. Then, when blasting furnaces, intermediate frequency furnace ramming materials How important is it?

When firing the furnace, cut the material ten centimeters thick, and then beat 6 times counterclockwise and 6 times clockwise, basically it takes half an hour to finish. According to the method, make it for another half an hour. If you want to build a one-meter-high furnace, the furnace time should be more than 5 hours. The furnace produced in this way is very lubricated, and the use time of the furnace is also longer.

Many manufacturers use quartz sand ramming material, frequency furnace ramming material, etc. when building furnaces, but when using frequency furnace and intermediate frequency furnace ramming material to wear through the furnace The furnace is built with high-alumina sand. Recently, the furnace is frequently worn. It used to be low-carbon steel. It may sometimes be cast iron, and sometimes a furnace of cast steel is made a day. I don't know why, why is it not durable in cast iron furnace after smelting cast steel?

The following editor will explain to you: dry fighting? Wet fighting? How big is the furnace? The quality of the knot? Furnace. High-alumina lining can be used for cast steel or cast iron melting, the key is the quality of the knot. In addition, when melting cast iron, the temperature should not be as high as that of cast steel, higher than 1500-1530 degrees Celsius. The key is the high-alumina lining, Low carbon steel is released at high temperature. At this time, the furnace lining is softened, creeping, and cracks may be hidden. The molten iron has good fluidity, forming cracks and drilling iron. It is not easy to find. It needs to be repaired. It may be more appropriate to use an acidic ramming material.
