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:What is the difference between industrial furnace masonry and ordinary masonry?
Of course, the difference is like the difference between a hog cap and a 100 story building. See the industrial furnace manual.
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's the role of anchor bricks in industrial furnaces?
Anchorage brick is a new type of anchor brick relates to an industrial furnace, in particular to anchor brick of an industrial furnace roof, including column hanging end and the anchor structure, opened in the anchor on the surface of the spacing of the grooves in the anchor on at least one surface is arranged along the length direction ribs is provided with ribs, the ribs of the reinforcement and anchorage tension, tensile and flexural strength was obviously improved, the stress generated in the groove at the bar at the barrier can not continue to transfer, so the anchor brick of this kind of structure is not easy to break.
Q:What is the difference in structure between industrial furnace and boiler?
From the way: industrial furnace (electricity, natural gas, gas, induction heating is considered electricity), boilers (coal, all kinds of hot exhaust gas, a variety of gas, seemingly less electricity).
Q:What is the difference between industrial furnaces and boilers?
Industrial kilns and industrial furnaces are collectively referred to as industrial furnaces. Industrial furnaces mainly refer to devices that heat materials by combustion reactions.
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:What are the combustion equipments used in industrial boilers?
Main auxiliary equipment for general boilers:1. domestic appliances 2. civilian gas boiler 3. industrial gas furnace.
Q:What are the advantages of a vacuum furnace?
The accuracy of furnace temperature measurement and monitoring is obviously improved. The indicating temperature of the thermocouple and the temperature of the furnace reach 1.5 C. But there is a large temperature difference in a large number of workpieces in different parts of the furnace. If the forced circulation of the rarefied gas is adopted, the temperature range of the temperature range of + 5 DEG C can still be controlled.
Q:How to use industrial furnace equipment?
If it is water cooling furnace door, but also to ensure the smooth flow of pipes, winter pipes are not frozen. When the boiler is in a limited position, the interlocking device for cutting off the power supply shall be provided when the furnace is in and out, and the number of broken wires in the pitch of the steel wire shall not exceed 10%, and the counterweight of the furnace door shall be reliably hung.
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.
