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.

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. Table of Contents CrNickel (Ni)MoWolfram(W)Vanadium(V) 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 … Waca liyane

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

Let ‘s just cut into the case. Table of Contents What is cold extrusion?Advantages of cold extrusion processWhat is cold heading?Advantages of cold heading processIs cold heading the same as cold extrusion? What’s the difference? 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 … Waca liyane

Characteristics and Application of Common Bearing Materials
