Applications:
submerged arc furnace taphole drill/block machine is used to drill and block tapholes for submerged arc furnace. This is a very mature machine. Our company has 20 years research and produce experience in this area, we hold more than 85% market share in this area in China. It suits for the submerged arc furnace above 5000kva.
Main advantages:
1. Ease the labor intensity and improve the working environment. One person operates the machine can do the furnace taphole drill/block works, which in the past need 5-6 labors.
2. Prolong the service life of the taphole and reduce the time for SAF repair. SAF repairments may result in great economical loss. Take Shanghai Shenjia Ferroalloy Company for example , in the past, the company should arrange a repairment for the furnace #601 every year due to improper maintenance of the taphole. During this time, the company loss about 890T SiMn and 440T LC-FeMn, the repair cost is about $75,000, plus other materials in the repair expenses, the total cost during the repair time (including the loss of value) up to $200,000. Using our machine, the original repair time once a year can be reduced to once two years.
3. Shorten the time for furnace taphole drill and block. It just takes only about 15 minutes from the tap hole drill until it is blocked, Timely outflow of hot ferroalloy will help to reduce heat loss, improve temperature of SAF. All these will ensure you a stable production of SAF.
4. Huge economic benefits. Reduce the times for SAF repairment, which ensures the normal production of SAF; Save energy consumption, when using burn device to open furnace taphole, it consume electricity for about 243.5kwh each time. But now with our machine you do not have to use burn device, this could save 767,000kwh electricity a year; Reduce the consumption of consumable materials and accessory material such as ladle, tractors, round steel, carbon bricks, clay brick, oxygen blowing tube and so on.
Take Shanghai Shenjia Ferroalloy Company for example, the economic benefits of one set furnace taphole-drill/mud gun machine brings to the #601 SAF is about USD$150,000 per year.
5. It can perform conveniently and safely because the action of taphole-drill/ block machine is stable, reliable and fast. With more than 85% market shares, our company is the leader in the manufacturing field of Submerged arc furnace taphole-drill/block machine in China. It is used for more than 100 SAF in China.
