Silica ramming mass lining for tundish

Because of low investment, induction furnace is still very popular in worldwhile. Out of power, financial and other elements limit, many steel plants can not do continues casting. In this way, the tundish can only do sequential for 2 or 3 heats, or even 1 heat. In this condition, many factories are using tundish board, which should be broken down after one casting.
Say for one 2-strands tundish, cost for one set tundish board would be 20-25 USD. One casting service life would be a very big cost, and also bring a heavy labor work. To sort out this problem, many of Chinese small factories choose to use silica ramming mass to do tundish lining. After every casting, they would operate as following:

1. Pure out all melton steel.
2. Blow the tundish nozzle with oxygen lance.
3. Clean slag inside the tundish.
4. Cool down the tundish in normal temperature.
5. Change the sizing nozzle.
6. Preheat the sizing nozzle and start to use the tundish again.

In this way, we should only change the tundish nozzle every casting. For the silica ramming mass lining, it would last at least 10 castings, which would save a big cost from using tundish board.

The importance of refractory design

Refractory design remains the most fundamental factor in furnace construction. Refractory design details and proven technology consideration is of paramount importance to come up with an optimum furnace life and to maintain productivity in the life span of the furnace lining.

The failure to produce a technically or operationally durable refractory design lining could give rise to premature deterioration of the refractory lining and furnace shell.

The premature failure of the furnace lining will lead to extensive heat losses, furnace bath shift, change in taphole orientation and alteration of the Pitch Circle Diameter. In this way, the pre-design of refractory lining is very important, we must pay attention to every details, finding out the most suitable refractories for each part.
