Composite alloy roller

Abstract

The invention discloses a composite alloy roller, which comprises five layers of structure forms sequentially including a chromium metal layer, a bonding agent layer, a hard alloy tungsten carbide roller ring, a nickel metal layer and an inner layer ductile cast iron layer from top to bottom, wherein reinforcing clamps are arranged among the five layers of structures, shock absorption blocks are connected under the inner layer ductile cast iron layer, and a groove is formed between the shock absorption blocks. The composite alloy roller has the advantages that the steel rolling operation rate is high, the rejection rate is reduced, in addition, the control of the steel rolling process is accurate, and the surface quality of steel rolling finished products is improved.

Description

technical field [0001] The invention relates to the field of alloy roll devices, in particular to a composite alloy roll. Background technique [0002] In the process of rolling round steel, square steel, bar, and wire, alloy rolls are used. Alloy rolls are also commonly known as alloy roll rings. Usually alloy rolls are made of cast iron, which has strong wear resistance and has a certain Toughness, alloy rolls are mainly used in the field of machine tools and pulverizers. In the production of machine tool steel rolling, alloy rolls are also continuously consumed and worn out. When the wear reaches a certain level, the alloy rolls need to be scrapped or replaced. If the wear is uneven, during the rolling process There will also be hazards. [0003] The life of traditional alloy rolls is relatively short in harsh environments, so that the rolling mill needs to be replaced after a period of time. For this reason, the present invention provides a composite alloy roll, which...

Problems solved by technology

[0002] In the process of rolling round steel, square steel, bar, and wire, alloy rolls are used. Alloy rolls are also commonly known as alloy roll rings. Usually alloy rolls use Made of cast iron, it has strong anti-wear ability and certain toughness. Alloy rolls are mainly used in the field of machine tools and pulverizers. In the production of machine tool steel rolling, alloy rolls are also constantly consumed and worn. When the wear reaches a certain level, Alloy rolls need to be scrapped or replaced. If the wear is uneven, there will be dangers in the rolling process.

[0003] Traditional alloy rolls have relatively short service life in harsh environments, making the rolling mill work for a period of time before replacing alloy rolls. For this reason, the present invention provides a composite alloy roll , which greatly improves the service life of alloy rolls and reduces the frequency and time of changing rolls
