Product Description

Ferro silicon is widely used in the steel making,iron casting ,low-carbon ferroalloy producing:

1 In the steel making field,Ferro silicon is used as deoxidizer and alloying agent to precipit and diffuse deoxidation.Adding a certain amount silicon of fe-si to the steel can obviously improve the strength ,hardness ,elasticity and permeability of steel.

2 In the iron casting,it is used as ball mile agent and alloying agent especially in the nodular iron casting, Adding ferrosilicon to cast iron ,it can prevent the formation of carbide and promote the precipitation of graphite and the nodulizing.then the mechanical capacity can be the same of steel's.

3 High-silicon ferrosilicon can be used for the production of the low-carbon reductant in ferro alloy industry.

4 In addition ,ferro silicon powder can be used as a suspended phase in the mineral processing industry and coatings for welding electrodes in the electrode manufactruing.

Q:Who know what kind of fire shutter fire rating are there?: There is no national standard for fire protection performance of fire roller shutter in China, and now the executive standard of GB14102-2005 "fire shutter": F1, fire-resistant time 1.50h; F2, fire-resistant time 2.00h; F3, fire-resistant time 3.00h; F4, fire-resistant time was 4.00h before the national standards of fire shutter grading is introduced, expert advice that fire resistance test be made according to national standard, to reach back fire surface temperature rise requirements, if the refractory limit is greater than or equal to 3.0h, it is said to be super fire shutter, if test not inspect unexposed surface temperature rise as a judgement of the conditions, the door is referred to as ordinary fire shutter doors. I hope my answer can help you

Q:Is there a worker in (Jigang refractory plant)?: Units in this way, it is necessary to slowly boil it, wages will come up. You are a labor worker, and can not share with the stock system staff. There's a difference between salary and vacation.

Q:Where is the production of refractory manganese alloy manufacturers? Manganese is recommended between 63 and 70!: There are a lot of silicon manganese alloy manufacturers, production market is relatively large, the manganese content in manganese alloys between 63 to 70 or more common

Q:What are the applications of refractory in petroleum?: It can be used in chemical filler. For general process, some insulation parts also need to use refractory.

Q:What's the fire endurance of hollow brick?: This question is really very simple. It is better no to exceed 1050℃, or it will be easily burnt. I think 980℃ is ok actually. Around 950℃, no more than 1100℃, or brick will be burnt and melted easily.

Q:How should refractory cement be used?: Refractory cement is very easy to use. Add some water and mix, and it will harden. Generally there is no need to add other binding agents, but you can add some refractory aggregate and powder. If you use only refractory cement, it will generate a lot of cracks after high temperature. Generally refractory cement can withstand temperature of about 1300 degrees.

Q:Is it normal for caable fire resistant material to catch on fire?: Abnormal; aging is certainly one of the cause of the fire. That is caused only because of poor insulation and aging caused by short circuit, but a more important reason is configuration of air switch does not meet the requirements. If the capacity of air switch equals that of the cable, trip will happen at the moment when current is overloaded, not causing a short circuit or over current fire.

Q:Concrete composition and function of magnesia bond used in refractory: According to the chemical composition and use can be divided into metallurgical magnesia, magnesia brick, magnesia brick, magnesia brick, magnesia calcium brick, magnesia brick and other varieties. Its performance is greatly affected by CaO/SiO2 ratio and impurities. High purity magnesia brick refractoriness under load and thermal shock resistance are better than the general magnesia brick. High refractoriness, has good resistance to alkaline slag and iron slag, is a kind of important senior refractories. Use of magnesia product production by sintering process, sintering temperature is 1500 ~ 1800 DEG C, in addition, you can also add chemical bond, made of brick and unshaped refractory material. Mainly used in open hearth furnace, electric furnace, converter, oxidation non-ferrous metal smelting furnace, cement kiln and alkaline refractory kiln etc..

Q:How about the prospect of refractory material?: Area depends the market. Resource-based industry

Q:What are included in fireproofing materials?: Incombustible?material of construction fire-proof material Grade A: Cement, stone, steel, coat, glass, aluminium alloy, ceramic tile, etc.; nonflammable material Grade B1: Fireproof?panel, rock wool.
