We understand that the steel industry requires a high degree of reliability and performance regarding maintaining critical temperature and humidity levels in locations such as: - Machine control centres - Switch gears - Electrical control rooms - Computer control centres - Operator control pulpits - Labs and office space

• A knowledgeable group of technical professionals assembles each one of our specially designed combinations. This is not an assembly line environment.
• Prior to shipment, each product we produce, pass through the quality control inspection and undergo extensive testing.

Our products operate in extreme environmental conditions including: - Corrosive Environment - Sulphurous and hydrochloric gases, lime and chlorine can destroy exposed aluminium and copper, and reduce air conditioners to scrap metal quickly.

Frigortec Air Conditioners, with their heavy-duty frames and epoxy-coated coils are protected from these types of destructive and corrosive elements. - Extreme Temperature - The operating range for Frigortec air conditioners is 15°C to 95°C - High Humidity - Frigortec air conditioners are designed to maintain and control specific relative humidity requirements.

Extreme Levels of Air-Latent Particulates - Airborne particulates found in steel and other metal manufacturing environments are taken into consideration in the design of Frigortec’s heat exchangers

Excessive Vibration - Overhead cranes and steel yards are two sources of excessive vibration.

Frigortec AC units are designed with flexible lines and hoses along with rugged frames made of heavy gauge steel to protect equipment from the effects of high vibration environments

Avid Impex specialize in the following mentioned Sections of Steel Plants when it comes to High Ambient Temperature Industrial Air Conditioning.

COKE OVENS AND COAL CHEMICALS :

Coke making is the process to convert coking coal, through a series of operations, into metallurgical coke. The process starts from unloading of the coal at the wagon tipplers & ends at sizing & transportation of coke to Blast furnace.

STEEL MAKING:

The Hot Metal also known as molten pig iron which is produced by Blast Furnaces contains various impurities. The primary impurity found is carbon, however there are also other impurities such as silicon, phosphorus, sulphur, and non-metallic inclusions. The process of purifying this hot metal is called steel manufacturing. Such generated steel is metal in its purest form.
Hot Metal contains around 4% of Carbon which is to be reduced below 0.10% as per the requirement. Other impurities like sulphur, phosphorus is also removed and alloying elements such as Manganese, Silicon, Nickel, Chromium and Vanadium are added to produce the exact steel required.

BLAST FURNACES

BF is a counter current heat and mass exchanger. Hot blast is supplied through the bottom of the furnace via tuyeres, while solid raw materials are charged from the top. Both the oxygen and the heat are transported from the burden to the gas and the gas to the burden. As coke and load pass through the furnace, gas rises through it. The reactions' counter current nature renders the entire process incredibly effective in lowering atmosphere. The ability to build massive blast furnaces was made possible by the development of high strength coke, which marked the true beginning of the advancement of blast furnace technology.

SINTER PLANT

Sinter plants agglomerate iron ore fines with other fine materials at high temperature, such that constituent materials fuse together to make a single porous mass. A large quantity of iron ore fines is generated in the mines which cannot be charged directly into the Blast furnace. Furthermore, the steel industry itself produces a large amount of metallurgical waste, the disposal of which is quite challenging. In order to consume this otherwise waste fine material, they are mixed with Iron ore fines and agglomerated into lumps by a process known as SINTERING. The process of sintering involves the agglomeration of tiny mineral particles into a porous, lumpy mass by initial fusion brought on by heat generated by the internal combustion of solid fuel.

HOT ROLLING

In the metalworking process known as Hot Rolling, metal is heated to a temperature higher than that of recrystallization to cause plastic deformation during the working or rolling action. By using this technique, forms may be produced with the same metal volume but with the required geometrical proportions and material qualities. To achieve a consistent thickness, lengthen, reduce cross-sectional area, and flatten the heated metal, it is passed between two rolls. The most frequent byproduct of the hot rolling process is hot-rolled steel, which is extensively utilized in the metal industry as a finished good or as a raw material for other processes. Hot rolling removes the boundaries and fractures the grain structures, allowing new, robustly bounded structures with homogeneous grain to develop.

An integrated steel plant's raw material handling plant (RMHP), ore handling plant (OHP), ore bedding and blending plant (OBBP) are crucial components. It serves as the foundation of an integrated steel plant, where all types of raw materials—aside from coal—used to make iron and steel are managed methodically. Examples of these processes include unloading, stacking, screening, crushing, bedding, blending, and reclamation.
