The importance of correct refractory design

As we all know, the refractory design remains the most fundamental factor in all furnaces 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 tap hole 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.
Our technical team can give you a perfect design which is suitable for your furnaces according to specific needs, please contact us freely if you’re interested.

The importance of refractories for ladle

Sliding refractory is a central part of the slide gate, is a key component in direct contact with the control of molten steel, its physical and chemical properties is a key factor in determining whether the normal use of the sliding gate.

Ladle well block is of low hot crushing strength. When using air pick to chance upper nozzle well block, the well block would be easy to breakdown. The inner diameter would get larger, and gap between well block and upper nozzle may get bigger. The molten steel would easy to get into the gaps, and leak would easy to happen.?Ladle well block is of weak thermal resistance. During working period, like casting and hot repair, the temperature difference would be very big, and the well block would easy to break down. If can not be found in time, molten steel would leak through the gap between upper nozzle well block and nozzle.

Ladle slide plate plate is of weak erosion resistance. When doing half hole casting, the lower plate would bear higher erosion strength, and easy to appear groove. After closed the plate, molten steel would leave in the groove and get cold there, in which way the two plates can not work smoothly.

If the low slide gate plate break down, gap would easy to appear when casting, and molten steel would leave through it. If terrible, the slide gate plate would easy to break into pieces because of molten steel pressure.

Ladle sliding gate plate mortar can not bear erosion well, in which way gaps would appear and cause leak. If can not be found in time, this would cause leak between upper nozzle well block and well block, upper nozzle and upper sliding gate plate.

Construction of fire plastic material

The construction quality of fire plastic refractory raw material affects the service life of the furnace directly. When doing construction on the top of the furnace, if the construction is improper, accidents such as roof vault or roof collapse will occur. Therefore, fire plastics refractory raw material must be constructed as follows:

1.Combining fire plastic material and anchor bricks;

2.When the first layer of refractory raw material is hammered, shave the surface of plastic material with a scraper so that the bonding surface is rough; then place the second layer of plastic material and hammered in the same way;

3.Cut the expansion joint according to the design requirements;

4.Lay holes in the plastic refractory raw material after construction.

Changxing refractory provides refractory products, calcium silicate products, castable & mortar, china refractory brick, ceramic fiber felt, ladle & tundish nozzle, ceramic fiber with high quality for you. Such as high alumina refractory bricks, magnesia carbon brick, clay refractory bricks and other refractory products.
