Main application of Aluminum-silicon alloy

Aluminum silicon alloy is a kind of forging and Cast Alloy, the main composition is aluminum and silicon, generally contained 11% silicon and add a few of copper, iron, nickel to improve strength, density 2.6~2.7g/cm3, thermal conductivity 101~126 W/(m· Celsius degree), Young's modulus is 71.0GPa, impact value 7~8.5J, fatigue limit ±45MPa

Ferro-Silico-Aluminum is a deoxidizer used in steelmaking, it can improve the shape of inclusion, reduce the content of gas element in liquid steel. It is an effective new technology to improve the steel quality and reduce production cost and save aluminum. It is especially adapt to deoxygenation requirement in continuous casting steel. Experience has proved that it is not only satisfy the deoxygenation requirement in steel making, and also has desulfurization function and has advantages of high specific gravity and strong penetrating power and so on.

Q: Selection of heat preservation material for industrial furnace: In the neutral and oxidizing atmosphere, the tensile strength, toughness and fiber structure can be maintained for long term use. The temperature is 950-1400 centigrade. Excellent chemical stability; excellent thermal stability; excellent tensile strength; low thermal conductivity; low thermal capacity; excellent sound absorption and noise reduction performance.

Q: What is the difference between industrial furnaces and boilers?: Hot water or steam generated in the boiler can directly provide necessary energy for industrial production and people's life, but also by the steam power device is converted to mechanical energy, or through the generator converts mechanical energy into electrical energy. Hot water boilers are called hot water boilers. They are mainly used in daily life, and are also used in industrial production. Steam generating boilers are called steam boilers, often referred to as boilers. They are used in thermal power stations, ships, locomotives and industrial and mining enterprises.

Q: Heat treatment equipment (industrial furnace), which products generally contain what kind of, which industries need to use heat treatment industrial furnace equipment.: The main equipments of heat treatment are classified into two major categories: main equipment and auxiliary equipment. The main equipment includes heat treatment furnace, heating device, surface modification, surface oxidation device, surface mechanical enhancement device, cooling equipment, cold processing equipment, process parameter detection and control instrument; auxiliary equipment includes cleaning cleaning equipment, furnace atmosphere heating medium permeability meter preparation equipment, cooling device, quenching medium heavy transport machinery, quality testing equipment, power transmission line and auxiliary equipment, fire safety equipment, dust and other production fixture.

Q: What are the companies in the world that are currently engaged in metallurgical furnaces?: There are many kinds of furnaces in metallurgical industry,colored and black,smelting and heat treatment are also included.

Q: What are the combustion equipments used in industrial boilers?: The main auxiliary equipments of the general boiler are: upper coal machine, ash blower, blower, draught fan, economizer, feed pump and water treatment unit. Oil boilers are: oil pumps, burners, tanks and so on.

Q: Why does the burner of industrial furnace burn occasionally?: The general process for burner ignition, blowing furnace, electric spark ignition, solenoid valve, open the gas in case of delayed spark ignition, detection device detects the flame, the controller accepts signal so that the solenoid valve open, gas continuous normal combustion. However, if the ignition fails or the burner fires, the detector cannot detect the flame, which causes the solenoid valve to close and the burner flameout.

Q: How many kinds of industrial electric furnaces are there?: Industrial furnace according to the heating mode is divided into two categories: one is the fuel furnace, combustion heat with solid, liquid or gaseous fuel in the furnace for heating the workpiece; the second is in the furnace, the furnace converts electrical energy to heat the heat.

Q: What are the advantages of a vacuum furnace?: High degree of integration of mechanical and electrical. On the basis of the improvement of temperature measurement and control accuracy, the workpiece movement, air pressure regulation, power adjustment can be programmed in advance, and quenching and tempering are carried out according to the steps.

Q: Brief introduction to repair of industrial furnace: The working condition of industrial furnace is very bad. It is affected by high temperature, slag erosion and burden wear. Therefore, its working condition changes quickly and its service life is short.

Q: What is an industrial furnace pit?: In twentieth Century 50s, coreless induction furnaces were developed rapidly. Later, electron beam kilns, using electron beams to impact solid fuels, strengthen the surface to heat and fuse materials with high melting point.
