Application Of Cemented Carbide Composite Roll Ring On Small Rolling Mill
The cemented carbide composite roll ring is used in the finishing and intermediate rolling stands of small rolling mills. Generally used in 2-10 stands abroad, at least two stands, namely the finished product and the front stand of the finished product, can be used at the same time. The best performance and benefits of the rolling mill are conducive to ensuring good working conditions of the composite roll ring of the finished stand, and improving the single groove rolling life and the quality of the rolled material.
The groove life of cemented carbide composite roll rings is about 10-20 times that of ordinary cast iron rolls, and the grinding amount is only 1/2 to 1/3 of that of cast iron rolls. Therefore, compared with traditional cast iron rolls, composite rolls The total rolling volume of the ring is 20-40 times that of ordinary rolls.
The application range of cemented carbide composite roll rings is very wide. The production of wire rods, bars, pipes and other small materials, such as square steel, hexagonal steel, flat steel, angle steel, etc., can be applied to this technology, which will greatly improve the performance of the rolling mill. Good results have been received. For example, when rolling 12ram rebar, the single groove rolling volume of the cemented carbide composite roll ring is more than 1300 tons, which is 16 times more than the single groove rolling volume of 80 tons of ordinary cast iron rolls; The grinding amount is 1.5-2.0mm, which is 1/2-1/3 of the cast iron roll 5-6ram. When rolling 20*3 spring flat steel, the single groove rolling volume of the composite roll ring is more than 1,000 tons, while the cast iron roll is 70-90 tons, a difference of more than 10 times.
