With the continuous development of the industry, Henan Raymond Mill has become the main equipment for grinding industry in China's powder industry. “High reliability, energy saving, precision, and automation are inevitable trends of its development. Experts believe that Henan Raymond Mill Machine The powder industry will mainly develop high reliability, energy saving, precise, automatic condition monitoring and automatic control, etc. It can adopt thyristor power supply, AC frequency conversion, grease lubrication, shock absorption and other measures, and Condition monitoring and microcomputer automatic control devices, among which the high reliability needs to rationally study the wear resistance of reinforced rings, lower glands and the like through the mechanical principle, and improve the lubrication of the machine before the continuous operation of the bearings. Monitoring and automatic control need to increase the intelligent electronic control system inside the Raymond Mill to automatically control the entry, exit, grinding, and dosing of materials, etc. The operator only needs to perform button control in the operation room. The accuracy of the machine.
Cold drawn steel bar is produced by hot rolled steel bar or wire rod to get smooth surface, more precision size, higher mechanical properties, which improves machining characteristics. It can also get various sections and sizes. So cold drawn steel bar is a better choice for machining users.
According to different steel grade, the production line is usually different. The Basic production line is as below:
For high carbon steel or alloy steel bars, to avoid the cracks in inner or surface, the bars are usually required to be annealed before cold drawing.
To get different mechanical properties or hardness depending on final usage, the cold drawn bars will also be heat treated such as annealed, normalized or quenched and tempered(Q&T).
For CNC machines usage, to get much more precision sizes or much more better surface roughness for chrome plating, the cold drawn steel bars can also be centerless ground or polished.
We have more advantages on producing cold drawn steel bars:
1) Big stocks of hot rolled round bars or wire rods as raw materials
2) Wide range of cold drawn steel bar sizes: from 10mm to 150mm
3) Different cold drawing medias powder or oil to get different surface
4) Straightening machines to get better straightness up to 0.5mm/m
5) Grinding and polishing machines to get better roughness upto 0.4um
6) Heat treating furnaces to adjust the mechanical properties
7) Full sets of testing equipment to test the sizes, mechanical properties and microstructure.
8) Multiple packages to avoid broken packages and anti-rusty
