Influence of operation on breakout of sliding nozzle

 1. When the water inlet is installed, it is not tightened, and the pin is loose. When the pin locking the sliding plate is not tightened, the surface pressure between the two sliding plates is small, resulting in looseness during casting, and molten steel is sprayed from the loose side to burn the mechanism;

2. The dilution and consistency of refractory mud during water distribution construction are not properly controlled. If the refractory mud is too thin, it will be extruded, which can not support the sliding plate brick. At the same time, it is not resistant to the scouring of molten steel, and it is easy to form steel at this position; If it is too thick, the refractory mud cannot be spread evenly. There is a gap between the upper nozzle brick and the sliding plate, and the molten steel will be drilled out of the gap. There is less mud between the upper water outlet brick and the upper sliding gate plate, the upper part of the upper sliding plate will lose support, can not keep close cooperation with the lower sliding plate, and the molten steel will pass through between the two sliding plates.

Advantages and disadvantages of fire clay brick

图片
According to production process, fire clay brick is divided into machine made brick and handmade brick. According to structures, fire clay brick is divided into solid brick and hollow brick, and hollow brick can be divided into load-bearing brick and nonbearing brick. Fire clay brick is made at different shapes according to different using requirements. Advantages of fire clay brick： 1. Fire clay brick is environmentally friendly and belongs to resource recycling bricks, so we can rest assured use fire clay brick. Fire clay bricks won’t be harmful to our health. 2.Fire clay brick has advantages of fireproof and heat insulation. Used clay brick can be used as concrete so that to save a lot of resources. 3.The price of fire clay brick is not as expensive as that of other fire bricks. Light weight brick is more expensive than fire clay brick. Besides, fire clay brick is very cheap and very durable 4. Fire clay brick has good moisture-proof function, it also has the a...

Installation of ladle slide gate and nozzle

图片
1.Before installing the upper steel ladle, first check the use of the water block brick. When the pit or crack occurs, use the repair refractory material to repair it, and then proceed to the next step. 2. Take the water pipe test, check the gap between the nozzle brick and the brick and the positioning of the nozzle brick. It is forbidden to manually remove the head of the water inlet and install it. 3. After checking the appropriate, remove the nozzle brick and apply refractory mud evenly on the outer wall of the upper nozzle brick. The thickness of the refractory mud is controlled at about 10mm (according to the actual clearance). When the gap between the nozzle and the brick is large, the asbestos cloth can be used. The head of the nozzle is evenly wound separately. 4. When installing the water inlet, the nozzle brick should be smoothly fed into the brick. During operation, avoid the gap in the lower part of the nozzle brick. 5. The water inlet must be re...

Blast furnace accident: six reasons for the freezing of the hearth

图片
1. The furnace is out of order. In many cases, the blast furnace condition is abnormal due to poor quality of the raw fuel or improper basic operating system. 2. Operational errors The prelude to the freezing of the hearth is the furnace cool. It is normal for the blast furnace temperature to fluctuate within a certain range, and the cool furnace that causes the hearth to freeze is often caused by improper operation. 3.A large amount of cooling water leaks into the hearth. 4. Long-term rest or sealing furnace Long-term rest is a common cause of freezing of the hearth even if there is no water leakage from the cooling equipment. 5. Equipment accident If the test is not enough before the start of the furnace, it will often cause equipment accidents. 6. The quality of raw fuel deteriorates. Wanhao is a manufacturer who is specialized in designing various kinds of furnace and making refractory products for electric furnace, ladle, tundish, bla...
