The advantages and characteristic of tundish dry vibration mix

 

Dry vibration mix is an unshaped refractory material that is vibrated and molded without adding water or liquid binder. Under the action of vibration, the material can form a dense and uniform whole, which can be strengthened by thermosetting bonding agent or ceramic sintering agent when heated. Dry vibration mix is composed of aggregate and powder、binding agent and additive.

Dry vibration mix's character is : this kind of material is easy to flow under the action of vibration force, and the powder can fill the tiny pores between particle accumulation even under the action of very small vibration force, and obtain a dense body with higher filling density. What's more, it is heated to form a working layer with certain strength. However, there is still a part of unsintered surface showing the original dense accumulation structure. This structure helps to reduce the stress caused by expansion or contraction; Prevent the spread and extension of cracks; Prevent the intrusion of financial melts and facilitates unpacking and cleaning. This material is used in the construction site by vibration method, which is simple in construction, short in construction period, without maintenance and baking, also can directly heat up the working layer and put it into use.

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...
