good quality price rate 3-split high speed bar hot rolling mill

the best quality in China at good price Chinese manufacturers. good quality, with ISO certification.

I have one good friend from south america that is looking for a partner/partners from inside china or from outside of china for the following project:

1. Buying a blast furnace factory with 4 BF (blast furnaces) on the basis of divided payments within several years.  (payment by instalments; hire purchase; instalment plan

keep up instalments)       the 1st BF got into operation ready for 1.5 year, the 2nd one for half a year. The 3rd one is ready to get into operation. The 4th one got 60% built. Their previous product is pig iron mould casting. now my friend plans to set up converter to make pig iron become steel and cast square billet for debar/round bar hot rolling.

2. buying a hot rolling mill (HRM) that was ready built but did not get into operation. The buying will be on basis of divided payments within 10 years.  (payment by instalments; hire purchase; instalment plan; keep up instalments) The HRM is from Germany. Production capacity is 300kt/y for making dia 12- 32mm bar.

3. the bar selling market is very good in that country: there are only 2 bar makers in that country, and the country is not small.

Technological process:

The bar will use cold billet or hot billet for production. They will be directly hoisted in rows to feeding roller way, then sent to the billet pushing roller way in rows for entering the billet-pushing type heating furnace for heating.

According to the different heating method and heating requirement for different kinds of steel, the billets will be heated to 1100 -- 1200 centidegrees, then sent to roughing rolling mill assembly for rolling via furnace delivery table.

The whole rolling line is composed of 17 stands of rolling mill, including roughing rolling, intermediate rolling and final rolling. The roughing rolling mill assembly and intermediate rolling assembly consist 11 stands of 2-roller high rigidity rolling mills with one DC motor driving 2 stands. The final rolling assembly is composed of 6 stands of high rigidity short stress line mills among which one stand is horizontal-vertical mill, all driven by DC motors individually. The roughing milling and intermediate milling adopt slight tension rolling for ensuring high quality product. In addition, for the sake of the work pieces getting into the rolling mills and for the sake of easy solving of accidents, before the final rolling assembly, one set of continuous fly shear is equipped to cut the head, tail of the work pieces and cut the work pieces in accidents.

For different kinds of products, the billets are rolled for 9 to 17 times to be Φ10Φ36 mm round bar, debar or small section steel. The max rolling speed of the finished product is 15m/s.

The debar coming out from the final rolling mill assembly goes through the reinforced bar penetrating-through-cooling-water-device, after on-line heat treatment, is sent to finished product multiple length fly shear for cutting. The water cooling device before the multiple length fly shear and the frequency inverting roller way are both loaded on a mobile carrier that can move transversely. According to production plan, the frequency inverting roller way or water cooling control device can be moved into or out from the position left for them so that super thin steel and alloy steel can be rolled.

The bar cut into multiple length,via cooling bed,is conveyed onto frequency inverting roller way and auto steel loading device for being sent to walking beam type notch-bar cooling bed to be straightened and cooled. At the side near the outlet of the cooling bed, there is a head aligning roller way to align the front end of bars.

After the bar is cooled to around 200 on the cooling bed, they will be collected in rows by a set of steel unloading device installed at the exit of the cooling bed. The cooling beds output roller way will send the bars in rows to the fixed cold shear for cut-to-length of 12 m or 9 m. the bars after cutting will be sent to the inspection table by roller way or finished product conveying chain for steel conveying and inspection. Qualified cut-to-length bar will be packed in bundles, weighed, name plate put and sent into warehouse.
