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

Light mullite brick with mullite (3Al2O3 · 2SiO2) as the main crystal phase of high alumina refractories. General alumina content between 65% to 75%. Mineral composition In addition to mullite, which contains lower alumina also contains a small amount of glass and square quartz; higher alumina also contains a small amount of corundum. Light mullite brick imported corundum corundum, high purity fused corundum as the main raw material, Application of advanced ultrafine powder to add technology, after mixing, drying, molding, firing in high temperature shuttle kiln. Mullite light brick is widely used in residue gasifier, ammonia synthesis of two conversion furnace, carbon black furnace and refractory furnace and other equipment. Product appearance size, physical and chemical indicators, the service life are to meet customer requirements.

Pre-melted refining slag is widely used as deoxidizer. It is mainly used in steel deoxidation and other impurities, with rapid slagging and other advantages, effectively reduce the inclusion of steel. It has features as follows: 1. Smelting smoothly, reduce the water splash, which can improve the liquid steel yield of about 1%. 2. Less time of smelting cycle. refining slag , high efficiency rate, can achieve smelting time is shortened. 3. To create a good dephosphorization conditions in the furnace. To achieve the purpose of pre-dephosphorization, improve the rate of 3% to 5% dephosphorization. 4. Accelerate the lime dissolved. There is no need to use fluorite to help melt, to achieve fluorine-free steel; furnace erosion to reduce the reduction of environmental pollution. 5. To be melted quickly. As a result of pre-melting, has formed a low melting point of the mixture. It will form into liquid once added into furnace, to achieve the purpose of smelting

1.Improve molten steel yield. By using tundish exchangeable nozzle, continuous casting heat number per tundish life is increased, upper nozzle open time is decreased, accordingly, remaining molten steel, wasted billet ends are decreased, thus the yield of molten steel is improved. 2.Improve billet quality. The first and last heat of one tundish life have great impact on billet quality, with the increase of continuous casting heat number, the number of fist and last heats are decreased, therefore the quality of billet is improved; 3.Stablize production schedule. Before using tundish exchangeable nozzle, the casting speed could be unstable and unpredictable because of the expand of nozzle diameter, which could lead to accident or shutdown, brings trouble to production. By using tundish exchangeable nozzle , not only such kind of trouble can be avoided, molten steel can be saved. 4.Lower labour intensity. The increase of continuous casting heat number decre

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

Domestic magnesite prices soaring, foreign markets are also affected. Originally relatively stable European market prices are rising higher and higher nearly six months because of the shortage of supply of Chinese magnesia. As researched, The current European market fused magnesia FOB prices rose to 700-960 US dollars / ton from the beginning of the 500-680 US dollars / ton, rarely over 40%. US market fused magnesia prices have also risen, but the increase is not about 10%. FOB US prices from the beginning of the 900-1400 US dollars / ton float to 1000-1500 US dollars / ton.

The unfired brick is a kind of refractory which is can directly used for constructiion use without adobe firing. Its production process is very simple. It is made by different refractory material after resonable gradation,then bonded with organic or inorganic cementing agent that has strong binding capacity. The main type of unfired brick (1) High alumina brick with the combination of aluminate cement  (2) Clay brick Combined with Portland cement (3) High alumina bricks with the combination of industrial phosphoric acid and aluminium phosphate (4) High alumina brick with sulfate binding (5) Ordinary brick with water glass combination (6) Magnesia brick with combination of magnesium chloride and Magnesium Sulfate. The advantage of unfired brick is good shock resistance. The defect is lower high temperature crushing strength than fired brick. So it can’t be used in the load-bearing part.
