Zhengzhou Yaojuxiang Industry and Trade Co., Ltd. is a diversified development enterprise integrating scientific research, production and operation. Production and sales of bulk refractories; metallurgical materials; steel-making accessories; Distribution: AD powder, AD ball, aluminium ash ball, aluminium slag ball, silicon-aluminium alloy ball, seamless calcium wire, alumina deoxidizer, dephosphorizing agent, desulfurizing agent, covering agent, slag remover, synthetic refining slag, fluoride-free slag agent, refining flux, refining slag washing agent, graphite foaming agent Additives, ladle modifiers, refining slag regulators, sodium aluminosilicate, calcium silicate, calcium aluminate, calcium silicate slag, expanded aluminium cake, aluminium iron, high aluminium powder, aluminium products, aluminium ash, aluminium slag, aluminium chip, aluminium powder, silica powder, cryolite, copper, aluminium, iron, carbon, and other metallurgical materials.
Supply: Aluminum-calcium spheres contain Al (> 30), Ca (> 20) (Aluminum-calcium sphere composition can be adjusted according to user's requirements). The product is suitable for electric furnace, converter, intermediate frequency furnace and out-of-furnace smelting. It can replace aluminium wire, calcium silicate, aluminium silicate and calcium aluminate to better meet the deoxidation and refining operation of molten steel. It has obvious effect on changing the shape of impurities in molten steel, refining fine grains, improving the processing performance of steel and improving the quality of steel products. Our company can also customize and produce metallurgical burden products of various specifications and indicators according to customer requirements.
The composition of aluminium and calcium in aluminium-calcium spheres can be controlled and adjusted according to the user's demand. The single sphere is made of high-tech ball pressing equipment with a particle size of 15-50 mm. The product is suitable for electric furnace, converter, intermediate frequency furnace and smelting outside the furnace. It can better meet the deoxidation of molten steel. Desulfurization effect.
With uniform chemical composition, low melting point and fast melting speed, it can shorten smelting time, no fluorine, no erosion of lining and ladle, no water absorption, no moisture absorption, easy storage and transportation. Because of stable phase and fast slagging, it can reduce the pollution of dust in steel mill, stabilize the refining process in an all-round way, free of impurities such as hydrogen, nitrogen and carbon. In order to improve the quality of steel.
I. Physicochemical Standards for Aluminum-Calcium Balls:
Al>40%, Al2O3:10-20%, MgO<3.0%, CaO:10-15%, SiO_2<6.0%, S<0.50%, P<0.50%; Specification:10-50mm
2. Characteristics of aluminium-calcium ball products:
1. Uniform chemical composition, low melting point, about 1365 C, fast melting speed, can shorten the smelting time.
2. No fluorine, no corrosion of lining and ladle.
3. The structure is compact, non-absorbent and convenient for storage and transportation.
4. Because of the stable phase and fast slagging, the dust pollution to iron and steel plants can be reduced and the refining process can be completely stabilized.
5. It does not contain impurities such as hydrogen, nitrogen and carbon, so as to improve the quality of steel with good metallurgical effect.
3. Practical methods of aluminium-calcium balls:
1. The composition of aluminium-calcium spheres can be adjusted according to user's requirements.
2. It is better to add ladle after moving to refining furnace or batch adding.
3.T steel consumption is 0.8-1.5 kg.
Packing, storage and transportation of aluminium-calcium balls:
1. Packaging material and single according to user's needs.
2. Waterproof, rainproof and moisture-proof measures should be taken during storage and transportation.
In order to implement the concept of green development, energy saving and cost reduction, the products of aluminium-calcium ball deoxidizer as steel-making auxiliary material have been well received after being used in many steel plants. During the use process, the occurrence of smoke and dust is reduced, the products of deoxidization are easy to float and discharge, and the price is lower than that of pure aluminium and other metals, which increases the efficiency of steelmaking and is widely used. Experiments on 70 t electric furnace smelting welding wire steel show that the expected results have been achieved, which provides a guarantee for the development of slagging materials for new varieties of Al-Ca ball steel in the future. Good products need good scientific research team. Yao Juxiang's strong scientific research support has become a strong backing for enterprises, sincere cooperation, unity and win-win situation. Our company also produces aluminium ash ball, aluminium slag ball and other products. Welcome to choose, sincere cooperation, mutual benefit and win-win situation. Clear development orientation of steel-making environmental protection, implementation of enterprise upgrading can play a greater advantage, cohesion plays the main theme of the times.
