Hrb500 stainless steel rebar. HRB500 tropical rib bar is old called four grade rebar, now also commonly called HRB500 thread bar, HRB500 is a hot rolled ribbed bar. In the construction industry, the grade of hot rolled ribbed steel bar consists of HRBS and the minimum yield point of that grade. HRB500 deformed steel bar in strength, ductility, high temperature resistance, low temperature performance, seismic performance and fatigue performance have been greatly improved than HRB400, mainly used in super high-rise buildings, high-rise buildings, long-span Bridges and other high standard construction projects, is the international engineering standards actively recommended and widely used in developed countries. The application of HRB500 steel bar shows that it can save a lot of steel and has obvious economic and social benefits. (www.zhishanginternational.com)

QUALITY IS THE BEST BUSINESS PLAN...A GLOBAL REPUTATION FOR LEADING-EDGE MANUFACTURING TECHNOLOGY. Suizhou Gaincin Machinery Co.,Ltd(info#GAINCIN.com.cn & showroom: gaincin.store.bossgoo.com)'s steel grinding media is a valuable commodity widely used in power stations for coal grinding, limestone grinding for flue gas desulphurisation, cement production, aerated building block manufacturing and in the mining industry, especially in gold, silver, copper and zinc mines.We also produce mild steel balls for use in ornamental ironwork to act as decorative finials on steel gates and railings. Rolled Steel Balls The major advantage of precision ball rolling, compared with traditional forging methods, is the uninterrupted grain flow. Grinding balls are rolled from selected carbon and alloy steels, produced to a customer’s precise specifications. A special feature of GAINCIN’s manufacturing process is the computerised quench facility, giving uniform surface hardness and controlled cross-sectional hardness essential for very even wear. Quality Control and Hardness Measurement In the long term, the effectiveness of grinding media must be measured by the final cost per tonne of product efficiently ground.GAINCIN's advanced manufacturing methods and materials guarantee the maintenance of the geometrical tolerances and correct structures vital to reliable, consistent performance and long life. GAINCIN’s products are rigorouslytested to ensure that they meet the agreed specifications. BALL HARDNESS:THRU HARD’OR‘TOUGH CORE’ GAINCIN’s expertise will ensure that you specify the most suitable grinding media for your particular application. GAINCIN’s ‘thru hard’ ball has a uniform high hardness from surface to core, thus maintaining very good wear properties down to very small diameters.The ‘tough core’ ball has a hard outer layer for long life, coupled with a tough, resilient core giving good impact resistance. Presenting the Hard Facts on Average Volumetric Hardness How hard is hard? The illustrations shown below tell an interesting story. Illustration ‘A’ shows an analysis of the cross sectional hardness of GAINCIN ‘thru hard’ ball. Illustration ‘B’ below shows the same analysis carried out on a ball from another major grinding media manufacturer. The ball in illustration ‘B’ has the same AVH figure as The GAINCIN’s ball and will wear out at the same time. Yet there the similarity ends. After three quarters of the radius, the hardness of the ‘B’ ball dips below that of GAINCIN’s ball. This brings into focus the area of greatest discussion about using AVH values. Over 72% of the final value is made up from the surface and 3/4 radius hardness readings. So AVH tells us relatively little about how a ball is going to perform once it has worn past that stage. The cross sectional hardness profile tells the full ‘inside story’. Q What kind of performance will the ball in illustration ‘B’ below give? A Once the ball has worn down to approximately 2/3 diameter, the remainder will wear away very quickly. Q How will this affect the mill output? A The rapidly wearing grinding media will give rise to an unstable and imbalanced ball charge, resulting in the possibility of more than one top up size being required to ensure the correct mesh of grind. Q How will GAINCIN’s ball perform? A The cross sectional hardness profile shows that GAINCIN’s ‘thru hard’ ball will wear evenly throughout its life. This will give a better size distribution in the mill, and avoid ‘dead zone grinding’. The shape of the ball will be preserved for much longer, giving a far more efficient grind. AVH =0.289 x Surface Hardness (S) + 0.437 x Hardness 3⁄4 R + 0.203 x Hardness 1⁄2 R + 0.063 x Hardness 1⁄4 R + 0.008 x Centre Hardness (C) The conclusions are obvious. High quality such as GAINCIN offers always saves money in the long run.

A GLOBAL REPUTATION FOR LEADING-EDGE MANUFACTURING TECHNOLOGY. Suizhou Gaincin Machinery Co.,Ltd(info#GAINCIN.com.cn & showroom: gaincin.store.bossgoo.com)'s steel grinding media is a valuable commodity widely used in power stations for coal grinding, limestone grinding for flue gas desulphurisation, cement production, aerated building block manufacturing and in the mining industry, especially in gold, silver, copper and zinc mines.We also produce mild steel balls for use in ornamental ironwork to act as decorative finials on steel gates and railings. Rolled Steel Balls The major advantage of precision ball rolling, compared with traditional forging methods, is the uninterrupted grain flow. Grinding balls are rolled from selected carbon and alloy steels, produced to a customer’s precise specifications. A special feature of GAINCIN’s manufacturing process is the computerised quench facility, giving uniform surface hardness and controlled cross-sectional hardness essential for very even wear. Quality Control and Hardness Measurement In the long term, the effectiveness of grinding media must be measured by the final cost per tonne of product efficiently ground.GAINCIN's advanced manufacturing methods and materials guarantee the maintenance of the geometrical tolerances and correct structures vital to reliable, consistent performance and long life. GAINCIN’s products are rigorouslytested to ensure that they meet the agreed specifications. BALL HARDNESS:THRU HARD’OR‘TOUGH CORE’ GAINCIN’s expertise will ensure that you specify the most suitable grinding media for your particular application. GAINCIN’s ‘thru hard’ ball has a uniform high hardness from surface to core, thus maintaining very good wear properties down to very small diameters.The ‘tough core’ ball has a hard outer layer for long life, coupled with a tough, resilient core giving good impact resistance. Presenting the Hard Facts on Average Volumetric Hardness How hard is hard? The illustrations shown below tell an interesting story. Illustration ‘A’ shows an analysis of the cross sectional hardness of GAINCIN ‘thru hard’ ball. Illustration ‘B’ below shows the same analysis carried out on a ball from another major grinding media manufacturer. The ball in illustration ‘B’ has the same AVH figure as The GAINCIN’s ball and will wear out at the same time. Yet there the similarity ends. After three quarters of the radius, the hardness of the ‘B’ ball dips below that of GAINCIN’s ball. This brings into focus the area of greatest discussion about using AVH values. Over 72% of the final value is made up from the surface and 3/4 radius hardness readings. So AVH tells us relatively little about how a ball is going to perform once it has worn past that stage. The cross sectional hardness profile tells the full ‘inside story’. Q What kind of performance will the ball in illustration ‘B’ below give? A Once the ball has worn down to approximately 2/3 diameter, the remainder will wear away very quickly. Q How will this affect the mill output? A The rapidly wearing grinding media will give rise to an unstable and imbalanced ball charge, resulting in the possibility of more than one top up size being required to ensure the correct mesh of grind. Q How will GAINCIN’s ball perform? A The cross sectional hardness profile shows that GAINCIN’s ‘thru hard’ ball will wear evenly throughout its life. This will give a better size distribution in the mill, and avoid ‘dead zone grinding’. The shape of the ball will be preserved for much longer, giving a far more efficient grind. AVH =0.289 x Surface Hardness (S) + 0.437 x Hardness 3⁄4 R + 0.203 x Hardness 1⁄2 R + 0.063 x Hardness 1⁄4 R + 0.008 x Centre Hardness (C) The conclusions are obvious. High quality such as GAINCIN offers always saves money in the long run.
