According to incomplete statistics, in 2014, the tidal grain sales of local food and agriculture accounted for nearly 70% of the total grain purchases in the year. The problem of “tidal food†processing needs to be solved urgently. In 2015, the Provincial Grain Bureau initiated the policy support for the reconstruction and upgrading of grain drying facilities on the basis of the comprehensive collection of grain and the extensive investigation and research conducted last year. In accordance with the actual situation in which our farmers sold and sold “tidal grain†problems last year, our district’s grain departments took the initiative to respond to, actively fight for, overcome difficulties, and dared to take on the responsibility. On May 22, It has successfully listed one of the 30 storage spots supported by the first batch of grain drying facilities in the province. The reconstruction project of the Yangtse branch storage and drying facility was officially launched in June 2015. Through planning, demonstration, construction, equipment procurement, and installation and commissioning, it was ensured that it was officially launched during the autumn grain acquisition period. The new drying equipment adopts advanced low-temperature drying technology, with a daily processing capacity of about 200 tons, which has played a positive role in relieving the local grain and agricultural tidal grain sales. The operation of the sheep-tip grain drying equipment for a month has dried more than 1,700 tons of grain. In the case of continuous rainy weather this year, it effectively solved the problem of farmers selling and selling tidal grains in the region, and won the praise of farmers in the region. Heat Treated Steel Bar And Tube
HEAT TREATED STEEL BAR AND TUBE
Heat treated steel bar is produced by heating and cooling in different temperature based on the steel grades to improve the steel bar mechanical properties or machinability for various industrial applications. Heat treated steel bar includes annealed steel bars, Normalized Steel Bar, quenched and temper qt steel bar.
Annealed Steel Bar has better ductility and lower hardness, which can be easier to be machined. The annealing processing is usually widely used for steel grade with higher carbon content above 0.5%. However, some low carbon steel also requires to do annealing for special usage such as 20CrMnTi gear steel. For some special material such as 20CrMnTi gear steel and GCr15 such bearing steel, spheroidizing annealing is often required.
Normalized steel bar sometime is also one kind of annealing processing. It mainly changes the grain to remove the impurities in steel and improves the strength and hardness. For some hot rolled steel bars, to keep the basic mechanical properties, normalizing is often used.
Quenching and Tempering, abbreviated as Q&T is a king of processing that strengthen or harden steel bars by heating the materials and then cooling in water, oil or other liquid medium, that rapidly the change from austenite to perlite to get the proper properties for various usage. The quenched & tempered steel bar materials are usually with carbon from 0.30% - 0.60%, it is widely used as merchant bars in components of various machines.
Our advantages on producing heat treated 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
