Most Common Treatments Used In Fabrication That You Should Know


Whether you're in the business of fabrication or oversee metallurgy operations, here are some of the conventional treatments used in fabrication that you should know. Every entrepreneur or industrial heaters manufacturers must be aware of these treatments. Understanding the fundamentals of these systems can help you make the right choice. Before diving into the different types of treatments, however, it's essential to understand the basics of heat treatments. 

What Is Heat Treatment?

Heat treating is a group of metalworking processes used to change the physical and chemical properties of a material. It entails the use of heating or chilling to extreme temperatures to achieve the desired results - hardening or softening of a material. The most common types of heat treatments are Annealing, Normalizing, Quenching, Tempering, and Hardening. Now, that we understand the heat treatment process, let's understand types of the heat treatment process. 

Types Of Heat Treatment

Annealing

This process refines and makes the material more comfortable to work with.  Metals are heated to a specified temperature for an extended period and then undergo cooling. Depending on the material, the cooling process can be fast or slow. 

Normalizing 
The process to achieve consistent grain size and composition throughout an alloy is called normalizing. This technique is frequently used on ferrous alloys. After normalizing, the metal cools in the open air. This process induces the production of martensite, pearlite and bainite; products that make steel malleable.  

Quenching 

The process of quenching involves cooling a metal at swiftly. Nitrogen gas is commonly used for this process, though sometimes even liquids and oils can be utilized. The impact of this process varies from alloy to alloy. Non-ferrous alloys become softer, and ferrous alloys harden when they undergo this process. 

Tempering 

Tempering releases the stress built up in material during the quenching processes. The metal is reheated at a low temperature, to attain a desirable combination of strength, hardness and durability. The time and temperature of tempering are highly controlled. 

Hardening

Hardening is a process meant to increase the durability of metal. During this process, the metal heats above the critical transformation temperature. Later it is cooled using quenching. Often hardening is followed by tempering to release stress. 

As an entrepreneur who oversees the metallurgical sector, these are the conventional treatments used in fabrication, you must know. With the right understanding of these treatments and the heat treatment process, you are equipped to make the right decisions.

What are Bi-Drum Boilers? How Do They Work?

Image
Bi-drum boilers are used for purposes of power generation and as process steam generators. This type of boiler is used up to 100MW for generating power. Bi-drum boilers are non-reheat units which are getting wiped out due to high heat rate of the plant. These boilers are used for generating high steam pressure which is used for power generation owing to their ability to accommodate high load of fluctuation and respond to load changes with more agility compared a single drum boiler. The two drums in the bi-drum boiler are connected using a large number of convective heat transfer tubes known as bank tubes or boiler bank tubes. These tubes are about one thousand in number. The bank tubes and the drum at the bottom that contains water will have a water level that will be up to the normal working level of water in the upper drum. The water availability in the bi-drum boiler makes it very adoptable for large load changes. Flue gases enter the bank tubes which are placed towards t...

How Do Electrostatic Precipitators Work?

Image
Reducing air pollutants is vital for human health and the health of the environment. Poor air quality has harmful effects on human health, particularly the respiratory and cardiovascular systems. Pollutants also damage plants and buildings, and smoke or haze can reduce visibility. Industries are largely responsible for causing pollution. They are also the ones who have access to a number of pollution control devices that absorb, filter, dilute, and disperse pollutants. One such device for pollution control is the electrostatic precipitator. This device works by removing particles and smoke from a gas stream using an electrostatic charge. Dust particles travel past wires that have a high direct current (DC) voltage applied, which ionises the surrounding gas. This corona discharge causes the particles to pick up a small electrostatic charge, without impeding the gas flow. Originally designed for recovery of valuable industrial-process materials, electrostatic precipitators are used a...

Quick overview of the Import & Export of Chemicals in India

Image
The chemical industry in India offers building blocks and essential raw materials for numerous industries such as paints, paper, textiles, pharmaceuticals, agrochemicals, soap, and detergents, etc. Let’s go through a few statistics of the chemical industry: The chemical industry in India is ranked 4th in Asia and 6th in the world. The global chemical industry is expected to be worth $4.7 trillion. The chemical companies in India contributes 3.4% to the global chemical industry. As of 2018, the chemical industry (including pharmaceuticals and fertilizers) stood at $163 billion. The Chemical sector in India is expected to grow at 9% per annum to reach $304 Bn by FY 2025. The expansion is anticipated to be pushed by rising demand in end-use segments for Specialty Chemicals and also for petrochemical intermediates. In 2015-16, the Chemical and Chemical Products sector accounted for 2.39percent of the GVA, compared to 2.23percent in 2014-15.18 Note: With India possessing a l...
