Furnace repair part and method of repairing furnace

 

EAF Furnace repair part:

The working conditions of each part of the lining are different, and the damage is also different. The main parts of the lining damage are as follows:

Furnace wall slag line: severely damaged by high-temperature arc radiation, chemical erosion and mechanical erosion of slag and steel, and oxygen blowing operations;
Slag line hot spot: In particular, the hot spot is also severely corroded by the influence of high arc power and off-arc. The degree of damage at this point is often the basis for furnace replacement;
Near the taphole brick: it is also easy to thin due to the erosion of slag steel;
Both sides of the furnace door: It is often damaged by rapid cold and heat, scouring of flowing slag, and collision between operations and tools.

EAF Furnace repair method:

Furnace patching methods are divided into manual patching and mechanical gunning patching. According to the different mixing methods of the selected materials, they are divided into two types: dry patching and wet patching.
At present, mechanical gunning is mostly used on large electric furnaces. The mechanical gunning equipment includes door gunning machine and furnace rotary furnace repairing machine. The mechanical gunning repairing furnace is fast and effective.

The principle of furnace repair is: high temperature, quick repair, and thin repair.

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...
