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 … Daha fazla oku

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 … Daha fazla oku

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 … Daha fazla oku

Characteristics and Application of Common Bearing Materials

As we all know, there are many kinds of bearing materials in the market. There are three kinds of common bearing materials: metal materials, porous metal materials, and non-metamaterials. Table of Contents Metal MaterialsBearing alloycopper alloyAluminum-based alloyGrey cast iron and wear-resistant cast ironNonmetallic MaterialsPorous Metal Materials Metal Materials Bearing alloys, bronze, aluminum-based alloys, zinc-based alloys, etc. are all metal materials. Among them, bearing alloys, also known as white alloys, are mainly alloys of lead, tin, antimony or other metals, which have low strength under heavy load and high-speed conditions. The reason is because of its characteristics, such as good wear resistance, … Daha fazla oku


Quenching crack is a common quenching defect, which is caused by many factors. Because the defects of heat treatment begin with product design, the work of preventing cracks should start with product design. It is necessary to select materials correctly and design structures rationally, put forward appropriate technical requirements for heat treatment, properly arrange technological route, select reasonable heating temperature, holding time, heating medium, cooling medium, cooling method and operation mode, etc. Table of Contents Material aspectStructural Design of PartsTechnical Conditions for Heat TreatmentQuenching CrackForging cracks Material aspect 1.
