General Comparison between Cast Iron and Steel

Cast iron and steel may look very similar on the surface, and they have different advantages and disadvantages from production to application. Understanding these advantages and disadvantages, and choosing the right ones may mean unforgivable differences between strength and durability and cracked or deformed parts, which can quickly lose luster. Carbon content Both iron and steel are ferrous metals mainly composed of iron atoms. In manufacturing, however, it’s not that simple. There are many different alloys and grades. In fact, carbon composition is the main difference between cast iron and steel. Cast iron usually contains more than 2.5% carbon, while … Waca liyane

Application of Grain Growth Inhibitors in Cemented Carbide

When WC grains in cemented carbide are less than 0.5 μ m, the finer the grains are, the fewer the defects are, and the higher the bending strength and hardness are The particle size of WC powder used to produce ultrafine cemented carbide is much smaller than that of WC powder used in general cemented carbide. The WC powder has high activity and is easy to cause grain growth in the sintering process, which is one of the crack sources. At present, there are two main methods to control the grain size: First, a new sintering process is adopted. The … Waca liyane

Something Informative about Metallurgy

Powder metallurgy is the technology of making metal powder or using metal powder (or mixture of metal powder and non-metal powder) as raw material, through forming, sintering, and manufacturing metal materials and various types of products. There are some similarities between powder metallurgy and ceramic production, which belong to powder sintering technology. Therefore, The metallurgy technology can also be used in the preparation of ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solve the problem of new materials and plays an important role in the development of new materials. Application fields of powder metallurgy First of … Waca liyane

What You Should Know about 3D Printing

With pricing of 3D printers comes down in modern time, it’s safe to say everybody have gotten the access to exert the machine for their own purpose. Before purchasing your own 3D printer, you are probably interested in 3D printer’s history and development. What is 3D printing? Comparing to material removal forming method such as drilling, it’s a process to adding material, which is called additive manufacturing, rapid prototyping, and solid free form fabrication, rather than removing excess material from workpiece. It was introduced for commercially use in the late 1900s by Charles Hull. Which is followed by many 3D industrial … Waca liyane

What-to-know about carbide parts commonly consumed in modern mining industry?

Someday you may feel the urge to learn about mining inserts and various drill bits tipped with them, whether you work for crude&gas industry, mining industry, or construction. I can see why it comes cause you realize works in these industries, more knowledge of tools you obtain, less hazardous condition and risk your guys will confront. As a manufacturer with exportation of mining tips gradually taking up one fourth of our whole annual throughput, we are thrilled to write this blog sharing some fundamental stuff about carbide mining tips that we are fabricating and familiar with. It couldn’t be better if it assists in knowing … Waca liyane

Do You Know the Cause of Failure of Mining Pick and the Way to Improve Its Performance?

Mining pick is one of the vulnerable parts in coal mining and roadway driving machinery, and it is the main tool for coal falling and coal breaking. Its performance directly affects the production capacity of coal mining machinery, power consumption, working stability and the service life of other related parts. With the increase of people’s demand for energy, especially for coal, in order to improve the mining efficiency, the power of the shearer is increasing, and the quality of the pick is required to be higher and higher. As the material of the shearer pick, it is required to have … Waca liyane

The Straightforward and Informative Intro about Common Elements Added into Alloy Steel

As is familiar to us, elements to be put into some kind of steel alloy for improving or altering its properties are regarded as alloy elements. Commonly used alloying elements are chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, silicon, manganese, aluminium, copper, boron, rare earth, etc. Phosphorus, sulphur and nitrogen also play the role of alloys in some cases. Cr Chromium can increase hardenability and secondary hardening of steel. It can improve hardness and wear resistance of carbon steel without brittleness of steel. When the content exceeds 12%, the steel has good high temperature oxidation resistance and oxidation … Waca liyane

Structure and Classification of Titanium Alloys

Base knowledge of titanium Titanium is an important structural metal developed in the 1950s. Titanium alloys are widely used in various fields because of their high specific strength, good corrosion resistance and high heat resistance. Many countries in the world have recognized the importance of titanium alloy materials, and have successively studied and developed them, and obtained practical application. Titanium is the fourth B element in the periodic table. It looks like steel and has a melting point of 1 672 C. It is a refractory metal. Titanium is abundant in the crust, far higher than common metals such as … Waca liyane

Is cold upsetting the same as cold extrusion? What’s the difference between them?

Let ‘s just cut into the case. What is cold extrusion? Cold extrusion of cold extrusion workpiece is to place metal blank in the cold extrusion die cavity. At room temperature, pressure is exerted on the blank through the fixed punch on the press, so that the metal blank can produce plastic deformation and the processing method of parts is made. Obviously, cold extrusion processing relies on the die to control the metal flow, and depends on the large volume of metal to rotate. Move to form parts. In terms of extrusion equipment, our country has the ability to design … Waca liyane
