Four kinds of common materials of ladle purging plug

 

Sintered magnesia purging plug: the sintered magnesia material refers to the refractory material with more than 80% MgO content, which belongs to alkaline refractory material. It has the advantages of high refractoriness, strong resistance to alkaline slag erosion, free from Ca and Cao erosion, and no pollution of molten steel.

Magnesia chrome purging plug: magnesia chrome material is a refractory material with MgO and Cr2O3 as the main components and periclase and spinel as the main mineral components. Chrome ore is not inert to steelmaking slag and has compatibility with other refractories, so the appearance of magnesia chrome material can improve the thermal shock resistance of magnesia material.

High alumina purging plug: high alumina material refers to the refractory material with more than 48% alumina content, which has the characteristics of high cold and hot strength, good wear resistance, heat shock resistance, spalling resistance and good volume stability at high temperature.

Corundum ladle purging plug: corundum material refers to the refractory material with more than 90% alumina content. Corundum is made of industrial alumina or bauxite after sintering or electric melting. When industrial alumina is used for electric melting, white corundum with more than 98.5% alumina content is obtained.

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...
