Sliding gate damage theory and meaning of conjunction

Ladle slide gate plate mainly contains two types, alumina carbon and alumina zirconium carbon. With steel production increasing and steel quality improving, calcium treatment process is applied, therefore, calcium content in the melton steel increased. Using alumina carbon and alumina zirconium carbon slide gate plate when casting steel, SiO2 and Al2O3 in the slide gate plate would mixed with [Ca], [CaO] in the melton steel or slag and get into low-melting point materials and feldspar, which would cause damage of slide gate plate. This type low-melting point materials would be easy to crushed down by erosion, new low-melting point material would re-appear. This progress would cause the erosion heavier, in which way the slide gate plate would be damaged gradually.

Conjunction of slide gate plate can reduce the number of turnover ladle, low down ladle serves and turnover pressure. In addition, slide gate plate conjunction can low down labor working, improve ladle lining temperature, thus low down casting temperature and bring a number of benefit for production and reducing cost.
From Year 2008, our factory succeed to develop double conjunction and from Year 2010, triple conjunction is developed. With the triple slide got into the normal production, on-site production, reduce labor intensity, the effect of reducing the cost of generation is very obvious.

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.
