How to choose insulation bricks

 

How to choose insulating bricks Insulation bricks used in thermal equipment can greatly reduce heat loss and furnace weight and improve thermal efficiency and labor productivity.

For most thermal equipment, in order to save energy and improve working conditions, thermal insulation is necessary. However, for some equipment insulation is not necessary because of the pros and cons of thermal insulation. Therefore, the actual situation and the performance of thermal insulation bricks should be considered when selecting suitable thermal insulation bricks.

The thermal insulation bricks can be divided into the following types:

1) Fireclay insulation brick GB/T 3994-2005

2) High alumina thermal insulation brick

3) Mulite insulation brick

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.

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...
