Synergy Group is one of the leading merchant producer of Pig Iron & Slags in India with production\ncapacity of 40,000 & 12000 tons per month respectively. The Company started operating in 2017 with\ntwo blast furnaces, making with annual installed capacity of 480000 Mt of Pig Iron & 144000 MT of Slag.
\n
\n FEATURES OF PRODUCT: <\/span>\n
\n
Pig iron is produced from the blast furnace. The purpose of a blast furnace is to chemically reduce and\nphysically convert iron oxides into liquid iron called \u2018hot metal\u2019. The blast furnace is a huge, steel stack\nlined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated\nair is blown into the bottom. The raw materials require 6 to 8 hours to descend to the bottom of the furnace where they become the final product of liquid slag and liquid iron. These liquid products are\ndrained from the furnace at regular intervals. The hot air that was blown into the bottom of the furnace\nascends to the top in 6 to 8 seconds after going through numerous chemical reactions. Once a blast\nfurnace is started, it will continuously run for four to ten years with only short stops to perform planned\nmaintenance.
\n
Pig iron is an intermediate product and first product of Iron making reduced from Iron ore. Pig iron has\na very high carbon content, typically 3.5\u20134.5%, along with Silica, Manganese, Sulphur, Phosphorus and other trace elements.
\n
\n USES AND BENEFITS OF THE PRODUCT: <\/span>\n
\n
Pig Iron comprises three main types: BASIC PIG IRON which used mainly in electric arc steelmaking, FOUNDRY PIG IRON used in mainly in the manufacture of grey iron castings in cupola\nfurnaces, and NODULAR PIG IRON (SG GRADE) used in the manufacture of ductile iron castings. Pig iron\nis used for steel making, foundries, alloy making, in automotive castings and other iron based castings.
\n
\n LEVEL OF CUSTOMISATION: <\/span>\n
\n
We produce compositions within fairly narrow ranges of specifications with the objective of optimizing\ncustomer's costs due to non\u2010addition of additives, standardization of process parameters and\nminimization of rejects. We are long\u2010term suppliers to some of the global brands & OEMs from\nautomobile industry and some of the most reputed steel mills and foundries. 
\n
Given below are the indicative specification of our pig iron grades which we supply to our valued\ncustomers primarily in India and also in Middle\u2010East, Far\u2010East, South\u2013East Asia:

BLAST FU<\/span>RNACE SLAG\n <\/h5>\n

Blast furnace slag cement is the mixture of ordinary Portland cement and fine granulated blast furnace slag obtained as a by product in the manufacture of steel with percent under 70% to that of cement. Ground granulated blast furnace slag cement (GGBFS) is a fine glassy granules which contain cementatious properties. In this article we discuss about the manufacture, constituents, properties, uses, advantages and disadvantages of Blast-furnace slag cement.
\n
GGBFS is obtained as a by product in the extraction of iron from it ore. The process of extraction of iron is blast furnace. The slag that is obtained on the iron ore is separated and cooled down slowly, which results in the formation of nonreactive crystalline material. The constituents of the GGBFS are as shown in the table below.
\n
USES OF BLAST-FURNACE SLAG\nCEMENT<\/b>\n
\n
1. Used in ready mix concrete plants.
2. Used for structures meant for water retaining such as retaining wall, rivers, ports, tunnels for improvement in impermeability.
3. Used in mass concreting works such as dams, foundations which require low heat of hydration.
4. Used in the places susceptible to chloride and sulphate attacks such as sub-structure, bored piles, pre-case piles and marine structures.
\n
ADVANTAGES OF BLAST-FURNACE\nSLAG CEMENT<\/b>\n
\n
1. The initial strength achieved is lesser than that of conventional concrete, but the higher ultimate strength gained is equal and sometimes higher that conventional concrete.
2. As the slag is grounded finely, it has the capacity to fill the pores efficiently, workability is high and bleeding is low.
3. It has good resistance towards sulphate and chloride attack and even less risk of alkali-silica reaction with aggregates.
4. Due to slow hydration process, the slump retention and initial setting time is more.
5. Greater durability and reduced permeability due to fineness.
6. The hydration process if slag is an exothermic process, thus the generation of heat of hydration is slow. Due to this property, this type of cement can         be used where the problem of thermal cracking is foreseen.
7.  As the colour of GGBFS is white, the cement colour obtained is lighter coloured when compared to conventional cement.
The production cost this cement is less when compared to OPC. <\/b>\n
\n
DISADVANTAGES OF BLAST-FURNACE\nSLAG CEMENT
\n
1. Initial Strength is low, due to this it cannot be used in RCC works.
2. As the initial setting time is high, this cement is not used for emergency or repair works.
