Abstract

The invention provides a method of producing an alloy plate hammer based on quenching and liquid die forging, belongs to the field of manufacturing of the plate hammer of a crusher, and is realized ona liquid die forcing machine based on a special alloy plate hammer die. The alloy plate hammer prepared through adopting the special alloy plate hammer die comprises the following steps of 1, smelting liquid steel; 2, preheating a die; 3, closing the die and performing cooling water circulation flow; 4, casting; 5, performing liquid extrusion; 6, performing demolding of blanks; 7, inspecting andfinishing; 8, performing process treatment of five-stage quenching + wind quenching + spray quenching; and 9, tempering. Technical performance indexes of the prepared alloy plate hammer are presentedas follows that 1, the hardness is improved by 10%-15%; 2, the tissue toughness of a casting is improved by 160%; 3, the weight is increased by 8%-15%; and 4, the service life is prolonged by 2 times.

Description

technical field

[0001] The invention belongs to the field of manufacturing blow bars of crushers, in particular to a method for producing alloy blow bars based on chilling and liquid die forging. Background technique

[0002] my country's metallurgy, building materials, road and bridge, mining, construction and electric power industries have a large number of large-scale crusher equipment of different specifications. During the working process, the crusher directly contacts with sand, soil, rock, minerals, etc., especially for granite and basalt. The strength is about 200MPa, and the fine-grained granite can be as high as 300MPa or more. The industrial and mining conditions are very harsh, and the blow bars are seriously worn out and fail, and the consumption is large. In metallurgy, building materials, mining, construction and electric power and other industries, the annual consumption of various metal wear-resistant materials in the country is more than millions of tons.
