Causes of partial breakout of sliding nozzle mechanism

 

Causes of sliding nozzle mechanism:

1) Due to long-time high temperature use, or inadvertent collision in operation, the sliding mechanism has large deformation, which leads to uneven stress on the sliding plate interface. Small gaps will be formed in the parts with small stress surface, which may cause steel penetration between sliding plates.

2) Due to long-time loading and unloading of the sliding car with the lower sliding plate, the error between the sliding car and the upper sliding plate mechanism will be generated slowly, resulting in the formation of small gap between the upper and lower sliding plates.

3) Because the spring used in the mechanism is used in high temperature environment for a long time, sometimes even though it is not in service, it may produce deformation and failure. Under the static pressure of molten steel, the gap between the sliding plates may appear, which may lead to steel penetration between the sliding plates. In serious cases, the whole mechanism may pass through the steel.

4) Due to the deformation of the top tightening sleeve of the water outlet, the installation of the water outlet is not correct, or the buckle of the sliding trolley of the top tightening sleeve of the water outlet is worn due to long-time use, so that the top tightening effect between the water outlet and the lower sliding plate can not be very good, resulting in steel penetration.

Wanhao is a manufacturer who is specialized in designing various kinds of furnace and making refractory products for electric furnace, ladle, tundish, blast furnace, AOD furnace, IF furnace, etc.

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...

The application of carburants

图片
Carburants are for casting iron. Carburants are added to steel, iron and carbon by carbon raw materials. High-quality carbon agent is essential for the production of high-quality steel auxiliary additives. At present, the vast majority of carburants are suitable for electric furnace smelting. Electric furnace smelting of the feeding method, the carbon agent should be with the scrap and other materials into the inside together, the addition of small doses can be added to the surface of the molten iron. But to avoid large quantities of molten iron to feed, to prevent excessive oxidation and the effect of carbon is not obvious and the cast carbon content is not enough. The amount of carbon agent added, according to the ratio of other raw materials and carbon content to set. Features 1.Absorption rate of it is up to 90% or more. 2.Improve the graphite form, increase the number of graphite, fine graphite, improve product mechanical properties, improve pro...

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...
