The main function of lining materials in heating furnace

 

The main function of the heating furnace is to heat the billet to the rolling temperature until it has sufficient plasticity so that it can be rolled to the required cross-section, size or shape by the hot rolling mill. The material chemical composition and grade are different, and the required rolling temperature also varies. According to the metallurgical properties and productivity of the raw materials, the heating rate of the heating furnace must also meet specific requirements and goals. During the process of the heating furnace, the material flow continuously passes through the heating furnace to heat the raw materials to a certain temperature.
The heating furnace is mainly composed of a regenerator that is insulated by refractory materials, a furnace that supports and transports heating elements, a furnace body, and a heat recovery system. The heating furnace uses oil, natural gas, electricity and coal as the main fuels as heat sources. The furnace temperature and pressure are controlled automatically, or manually.
Refractories play an important role in controlling energy consumption and improving the efficiency of heating furnaces. The service life of refractory lining and the production efficiency of heating furnace depend to a large extent on the correct selection of refractory materials, design results and precise masonry methods.

The function of lining materials in reheating furnace is to prevent heat loss of furnace body and ensure low surface temperature of reheating furnace body, so as to meet the safe working conditions around the reheating furnace body, thus helping to achieve the target of unit fuel consumption.The design of refractories also takes into account the minimization of heat loss on side walls, top and bottom.

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...
