Ferro Silicon Ferro Silicon has a melting point of 1200�¯�¿�½?�?�°C to 1250�¯�¿�½?�?�°C with a boiling point of 2355�¯�¿�½?�?�°C and Ferro Silicon contains about 2% of calcium and alluminium. Ferro Silicon, as an additive to the production process of ferrous metals, will impart several desirable properties upon the resultant alloy. Some of the primary benefits of adding Ferro Silicon to an alloy is to improve the corrosion resistant properties of the new compound, as well as to add to the high temperature heat- resistance properties of the new alloy, for example, in the production of silicon steel for use in transformer cores.
FerroChrome is a kind of Ferro alloy which is formed by Ferro and Chrome,it is an important alloy addition in steel making. Ferrochrome (Fe Cr) is an alloy of chromium and containing between 50% and 70% chromium.

Note: This is a 100A:3B mix ratio product that must be measured by weight. The choosing of suitable hardness should be according to the size and pattern design of the products. If large products and therefore multiple-piece molds are needed by customers, silicone rubber with higher hardness will be required for the molds. Conversely, soft silicon is indispensable for molds with complicated pattern and delicate details. The amount of curing agent admixture depends on the actual need of customers. More will be added for speedy drying and fast release and less when otherwise.

We offer superior quality sponge iron that is also known as direct- reduced iron. Our offered sponge iron is made for high grade, 65-70 fe
Min fem-80%, fet-90-92%, s-0.04% max. Loose in form of lumps.
Sponge iron filter material In industry through a sponge iron production equipment is widely applied iron phosphorus reduction method, method of reduction of iron ore concentrate, etc., the rolling iron phosphorus or ore concentrate after reduced iron press down into pieces, into the roasting tube into the kiln roasting, produce the high quality reduced iron. Sponge iron filter material for the first time into the deaerator, must first after backwashing, remove the sponge iron residue on the surface of the filter material float ash impurities.
Introduction of rtv 2 molding silicone rubber:
1. Two-part of rtv 2 molding silicone rubber: flowable liquid silicon and catalyst.
2. Rtv 2 molding silicone rubber cures at room temperature within 4-6 hours.
Features of rtv 2 molding silicone rubber:
1. Rtv 2 molding siliconerubber has an exceptional fluidity and good operability.
2. Rtv 2 molding silicone rubber hasgood temperature and deformation resistance as well as low shrinkage.
3. Rtv 2 molding siliconerubber has high duplication times.
Operation step for rtv 2 molding silicone rubber:
1. Step one to use rtv 2molding silicone rubber: take 100g of part a and add 2g of part b and mix thesilicon rubber and the curing agent evenly.
2. Step two to use rtv 2molding silicone rubber: vacuum pumping
3. Without exception, thistakes less than 10 minutes. Otherwise, it will cause cross linking reaction, and no more further steps will be available.
4. Step three to use rtv 2molding silicone rubber: brushing cast & perfusion molding operation.
