How to Buy Proper Melting Furnaces?
2023-03-23
In the forging industry, melting furnaces are widely used and frequently replaced. However, the quality of melting furnaces on the market is uneven, making it difficult to choose. So, how can you buy the right melting furnace? Today, Luoyang Hongteng will give you a detailed introduction to the knowledge about melting furnaces and how to choose a melting furnace. What Is A Melting Furnace? A melting furnace is a furnace or electric furnace used to heat iron, steel, or other metals. A furnace heats metal to a temperature that makes it easier to shape it by forging or heats it until it melts into a liquid state before casting it. Types and Working Principles of Melting Furnaces There are many types of melting furnaces depending on factors such as heating methods and uses. Electric Arc Furnace: An electric arc furnace is a furnace that uses electric arcs to heat and melt substances. It is usually used in metallurgy, steel, non-ferrous metals, and other industries. The method of use is to put the material into the furnace and discharge the electrode into the furnace to generate arc heating until the material melts. Induction Furnace: An induction furnace is a device that uses...
Application of Electric Induction Melting Furnaces in Scrap Metal Recycling
2023-03-14
Electric induction melting furnaces is a kind of heating equipment, which is widely used in metal heat treatment, thermoforming, metal smelting, and other industries. Electric induction melting furnaces play an important role in melting scrap steel, scrap aluminum, scrap copper, and other materials and recycling the corresponding metals. Today, we will introduce to you the application of electric induction melting furnaces in scrap metal recycling. Recycling and reuse of ferrous metal scrap steel Recycling, smelting, and reusing scrap steel to produce steel (short-process steelmaking) can reduce mine waste by 97%, reduce air pollution by 86%, and reduce air pollution by 76% compared to steel obtained from mining and smelting (long-process steelmaking). It can reduce water pollution by 40%, save 90% of raw materials, and save 74% of energy. What are the sources of steel scrap in steel mills? The steel scrap produced in the process of steel products and industrial manufacturing accounts for about 20-25% of the total scrap steel, mainly including the trimmed head, trimmed tail, chips, scraps, etc. of steel materials. Various waste equipment, steel structural parts, “scrap” locomotives, vehicles, rails, automobiles, ships, tools, utensils, etc., also generate a large amount of “depreciation scrap”. The scrap steel above...
What Products Can the Hot Rolling Mill Machine Roll?
2023-03-06
With the development of the steel rolling industry, the hot rolling mill machine is widely used in the continuous casting and rolling production line. Due to the excellent properties of high strength, good toughness, easy processing, and good weldability, hot-rolled steel products are widely used in manufacturing industries such as ships, automobiles, bridges, constructions, machinery, and pressure vessels. Hot rolling is to use slabs (mainly continuous casting slabs) as raw materials, and after heating, the rough rolling unit and the finishing rolling unit are used to make strip steel or steel bars. With the increasing maturity of new control technologies such as hot-rolled dimensional accuracy, plate shape, and surface quality, and the continuous emergence of new products, hot-rolled steel sheets and strip products have been more and more widely used and have become more and more competitively in the market. So, what products can the hot rolling mill machine roll? Hot Rolling Mill Machine Final Products There are many products that can be rolled by hot-rolled steel machines. According to the material and performance of rolled products, they can be divided into the following categories. a) Ordinary carbon structural steel b) low alloy steel c) alloy steel According to the...
Common Malfunctions and Treatment Methods in Steel Bar Production Line
2023-03-01
In the steel bar production line, there are various malfunctions occurring during production, such as the billet failing to enter the rolling mill, steel billets stacking before the rolling mill, and the rolled pieces being pulled to break. These malfunctions can seriously affect the efficiency of the steel bar production line. So, how to deal with these faults in the steel bar production line? Today, Luoyang Hongteng will introduce you in detail. Rolled Piece Fails to Enter the Rolling Mill Causes Rotten head, split head, blackhead, etc. of the rolled piece; incorrect or too small installation of the inlet guide; sticky iron or foreign matter in the inlet guide; too large or too small turning angle of the rolled piece; rolling guide wheel does not turn Or the bearing is burned out; the roll does not rotate due to fracture or connection; the roll gap is not adjusted properly or the size of the incoming material does not meet the requirements; the friction coefficient of the rolling pass is too small (new pass), etc. Analysis, Treatment, and Preventive Measures 1. Analyze the reasons for the non-feeding of the rolled pieces, strengthen the inspection of the head defects of the...
What Determines the Cost and Price of an Induction Furnace?
2023-02-20
Induction furnaces are widely used in the forging industry and the casting industry. The induction furnace is divided into the induction melting furnace and the induction heating furnace. The inductive melting furnace is used to melt the metal, and the induction heating furnace is applied to metal ingredient heating. In the metallurgical and casting industry, an induction furnace has become an indispensable production equipment. So, what is the cost and price of the induction furnace? Why is the price of induction furnaces in the market a huge difference? Today, Luoyang Hongteng analyzes in detail for everyone. 1. First of all, there are countless manufacturers selling inductive furnace equipment in the market. The price of induction furnaces produced by different manufacturers will definitely be different. Even, sometimes the price of the heating furnace is very different, and the price is large and uniform. One of the important reasons is that each manufacturer’s pricing standards for the product are different. 2. The sensor furnace model is different and the price is different. There are many models of steel rod induction heating furnaces, and different models of steel rod heating furnaces are very different. For example, the price of the 1 ton induction...
How to Scientifically Maintain the Stainless Steel Melting Furnace?
2023-02-17
The stainless steel melting furnace is an important piece of equipment for most steel mills. Its long-term safe use is inseparable from our scientific maintenance. So, how to scientifically maintain a stainless steel melting furnace? Today, Luoyang Hongteng is here to introduce it briefly. Several Points for Starting and Shutting Down the Stainless Steel Melting Furnace In the early stage of use, the sintering layer is thin, and it should be used to avoid high-power delivery as much as possible. Excessive electromagnetic stirring is generated to cause injuries to the furnace. Usually, it does not exceed 60-80%of the total power within the first 48h. After the work of the electric furnace, regardless of any reason, the cooling water system should be circulated by 4-5h, and at the same time, the temperature in the furnace is lower than 200C, otherwise, it will cause damage to the furnace lining and inductive coil and even scrap. The method of cooling the furnace is the iron liquid, and the natural cooling or cooling down with a fan and a duct. The cooling furnace cooling is convenient for the next inspection to open the furnace. Each time to start the furnace, you should clear the...
